In this article, you will learn more about topics such as:
Plastic fabrication refers to the crafting, production, and assembly of components using plastic materials or composites. In today's world, where an enormous variety of plastic goods exists, numerous plastic fabrication techniques have been developed. Each technique offers unique benefits, catering to specific design requirements. Manufacturers often prefer plastic fabrication due to its cost-effectiveness and adaptability, making it an ideal solution for a wide range of products across diverse industries.
Plastics are broadly classified into thermosetting plastics and thermoplastics, distinguished by their ability to be reshaped under different temperature and pressure conditions. Thermoplastics are characterized by their capacity to be remolded multiple times, as their molecular structure allows for repeated softening, melting, and reformation, unlike thermosets, which are permanent once set.
Within thermoplastics, there are crystalline and amorphous types, chosen depending on the specific application. Crystalline resins include nylon, acetal, thermoplastic polyester, and polyethylenes, while amorphous resins cover PVC, styrene, ABS, and polycarbonate. These resins are adaptable to various fabrication processes, enabling them to be melted, shaped, and joined.
Thermosetting plastics, once fully cured, cannot be melted or reshaped but can be cut, machined, and adhesively bonded. They include robust materials like phenolics, bakelite, G-10, and GPO polyesters, which are prized for their strength and suitability for insulating and structural purposes.
Both thermosets and thermoplastics are further divided into seven categories based on their molecular structure, which also designates their recycling codes. These categories are symbolized by triangles indicating the type of plastic in the material.
Plastic fabrication encompasses a range of processes, each tailored to the specific properties of the material and the desired outcome. The most widely used plastic fabrication techniques include:
Plastic welding, just like any other welding method, involves the melting of the workpieces to be combined in order to create a molecular bond between them. There are three main stages in plastic welding, which include pressing, heating and cooling. In order to fuse plastics, a filler rod is used that is of the same type of plastic as the pieces to be united. The process is performed after the surfaces to be joined have been heated to the plastic state or melted and the filler rod, also heated, is forced into the joint between the combining substrate.
The filler rod acts as an adhesive, bonding the plastics together for enhanced durability. Plastic welding can be performed through various techniques such as contact welding, spinning, high-frequency vibration, hot gas emission, and ultrasonics. Each method varies in terms of cooling processes, mechanical factors, and procedural guidelines. The selection of the appropriate method depends on its benefits and associated costs.
The second plastic fabrication technique is known as compounding, or the blending process. This method involves mixing two or more types of plastics with additives to create a composite material.
Afterward, this mixture is shaped into various parts using molds, dies, and other forming tools. The goal of compounding is to produce a material that is easy to process while meeting specific requirements, as it alters the thermal, physical, electrical, and visual properties of the plastic. Commonly used compounds in this method include polymer fillers, pigment masterbatches, base resins, blowing agents, and purge compounds.
The plastic lamination process involves bonding multiple layers of plastic together to form a protective barrier on the surface of another material. This technique not only enhances the product's durability and appearance but also reduces the likelihood of maintenance by safeguarding materials that are prone to wear and deterioration.
Plastic lamination is commonly performed in two ways: film and resin lamination. Both methods apply heat and pressure to create a protective barrier, but film lamination is often considered more effective. Resin lamination is typically used to create adhesive layers between materials like paper and fabric.
One significant disadvantage of this method is its time-intensive nature, which results in a slower production rate compared to other plastic fabrication techniques. Nonetheless, the plastic produced through lamination offers superior properties, such as enhanced strength, rigidity, and temperature resistance.
Plastic molding is a long-standing and widely used process in the plastic fabrication industry. It involves heating and melting plastic, which is then poured into a mold where it hardens, taking on the desired shape.
Plastic molding has various types, a few of which are discussed below.
Injection molding involves injecting molten plastic into a mold, where it cools and solidifies into the desired shape. This technique is highly versatile, making it suitable for producing both large items like automotive components and smaller products such as medical instruments. While the initial costs are high, the process becomes cost-effective when used for large-scale production. The process can be broken down into six primary steps:
Compression molding involves heating plastic and then using a press to compress it into a mold. This is followed by a curing process to ensure the final product retains its shape and strength. This technique is effective for creating products with varying lengths, thicknesses, and complexities. Items produced through compression molding are typically stronger, lighter, stiffer, and more resistant to corrosion compared to metal parts. Additionally, this method allows for the creation of complex designs. Although it is not as fast as injection molding, it provides a level of detail and intricacy that is hard to match.
This method is used with thermosetting plastics and includes four key steps.
Rotational molding, also known as roto-molding, is a plastic fabrication process used to create hollow components. This technique involves rotating a mold filled with heated plastic, which coats the interior surfaces and gradually builds up layers to form the final product. Compared to other molding methods, rotational molding has lower overhead costs since it operates without pressure, making the molds relatively inexpensive.
This cost-effectiveness extends to short production runs, making it an economical choice for various applications. The method's flexibility in mold shape and size allows for a wide range of products, from canoes and automotive parts to toys and buoys.
Additionally, rotational molding is highly efficient as it generates minimal waste; excess plastic can be reused in the production of subsequent parts.
Blow molding is another plastic fabrication process that involves the heating of plastic and transferring it into a mold. In this method, the tubes of plastic called parison are heated and transferred to the mold, then at the opening of the tube, the air is blown in to inflate the tube into the desired shape.
Blow molding uses thermoplastic pellets such as high-density polyethylene, polypropylene, polystyrene, or polyvinyl chloride. This method includes three primary types: extrusion blow molding, injection blow molding, and injection stretch blow molding. Despite some differences in the specific steps, all these methods share the core principle of blowing air into heated plastic tubes to form the desired shape. Blow molding is commonly used to produce items like bottles and fuel tanks.
One of the key benefits of blow molding is its low cost for tools and dies, coupled with rapid production rates. However, products manufactured using blow molding typically have limited strength.
Plastic extrusion is a continuous process in which raw plastic is heated and pushed through a chamber to be formed into a continuous profile such as pipes, tubes, films, fencings, deck railings, window frames, etc. The melted raw plastic called resin is pulled inside a heated barrel and then pushed out from the mold to get the desired shape. This is a high-volume production process.
The extrusion process begins with plastic granules being fed into the extruder's chamber from a hopper. Inside the chamber, the granules are gradually melted by heat generated from the rotating screw and external heaters. The molten plastic is then forced through a die, which shapes it into the desired form, and subsequently cooled to solidify.
Manufacturers favor plastic extrusion for its speed, consistency, and durability. Products created through this method generally withstand stress better compared to those made with other plastic fabrication techniques, as the continuous profile of extruded plastics lacks seams.
Thermoforming is another plastic fabrication process in which the thermoplastics are heated and reshaped under pressure. It is a unique process that involves the use of very thin plastic and carried out by various techniques including bending plastic sheets and vacuum forming. In this process, the tooling cost is considerably low in comparison to other fabrication processes because the thermoformed part does not need high temperature and pressure conditions to be fabricated.
As a result, molds used in thermoforming are typically constructed from materials such as wood, plaster of Paris, plastic, or aluminum. This process is both versatile and effective, commonly employed in producing packaging for food, disposable cups, toys, aircraft windshields, and cafeteria trays.
Die-cutting, another plastic fabrication process that employs specialized machines and machine tools to convert raw material by cutting, forming, and shearing it into custom shapes and styles. It's a flexible method that supports customization. The die-cutting process is suitable for a good range of geometries. It also has applications in various areas, including die-cutting neoprene, gasket, die-cutting paper, packaging, die-cutting fabric, and producing die-cut foam.
Die-cutting stands out as a highly efficient method for cutting film and thin plastic sheets into final shapes. Common plastics processed through die-cutting include polycarbonate film, polyester film, and HDPE sheets. The benefits of this technique encompass rapid production speeds, suitability for unskilled workers, and economical tooling costs.
Pultrusion involves applying continuous force to fibers as they undergo mechanical movement. Initially, fiber braids are immersed in a resin bath before being drawn through heated metal dies. This process is effective for creating both solid and hollow components, such as flat bars and tubing.
Although pultrusion can be costly due to the specialized tools required, it is valued for producing parts with exceptional smoothness and strength. Depending on the resin composition, products can also be resistant to flame, heat, electricity, chemicals, or environmental factors. Consequently, this method is frequently used in manufacturing furniture and machinery for chemical plants or agricultural settings. It is particularly suited for applications where dimensional precision and high fiber volume fractions are critical.
Advantages of pultrusion include a low waste rate, precise fiber volume control, and excellent alignment. However, the process does have some drawbacks, such as the need for a significant initial investment and skilled labor.
Forging is a plastic fabrication technique where a workpiece is shaped by applying blows from a hammer or other tools. This process enhances the material's strength and toughness, making it more shock-resistant through metallurgical changes.
Forging methods are categorized based on the temperature conditions used: cold forging and hot forging. Hot forging involves heating the workpiece before shaping it. By applying heat above the recrystallization temperature, internal gases are expelled, and the grain structure is refined during recrystallization, resulting in a stronger material.
Conversely, cold forging shapes the material at room temperature. This method provides high precision and increased toughness. Cold forging is commonly used for producing tools, cutlery, and components for vehicles and railroads. Additionally, forging is employed in the production of golf drivers, allowing them to withstand the impact of powerful strokes.
Vacuum casting, also known as polyurethane casting, involves using silicone molds to create plastic and rubber components under vacuum conditions. This versatile process can replicate injection molding techniques, producing intricate parts from polyurethane resins and cast nylon.
The vacuum environment ensures high-quality, bubble-free castings with a smooth surface and no imperfections. Vacuum casting is a cost-effective method for producing high-quality, low-volume plastic parts that closely resemble those made through injection molding. These parts are ideal for form, fit, and performance testing during the design phase, as well as for marketing, user testing, and product design validation.
Various vacuum casting resins are available to meet diverse design specifications, including temperature resistance, surface texture, and hardness. Materials can be chosen to produce parts that are opaque, translucent, or fully transparent. Additionally, high-quality wax for investment casting can be produced using this method, enabling the creation of detailed and intricate features.
Once the part has been produced, it moves on to the finishing stage. This phase may involve additional machining or joining processes depending on the specific needs of the part. While some finishing steps are primarily for aesthetic enhancement, others are essential for achieving particular functional goals. Regardless of the purpose, this final step is crucial and must be completed after the part has been fabricated.
When a joining process is necessary, welding is often the preferred method. This process is similar to metal welding and is used effectively with materials like polyvinyl chloride tanks. Typically, surfaces are joined by bringing them into contact and applying heat either through conduction or electrical means.
For heat sealing, especially in luggage made from blow-extruded polyolefins such as polyethylene and polypropylene, a hot sealing bar is commonly used. PVC, due to its high dielectric loss, can generate heat throughout the material when exposed to a high-frequency, high-voltage field.
Following the machining or joining process (or if they are not required), each part undergoes three finishing stages: de-flashing, cleaning, and coating/decorating. The de-flashing stage involves removing excess material that may remain from previous manufacturing steps. This surplus must be eliminated to ensure the final product meets quality standards.
Next, the cleaning stage addresses any leftover material that may adhere to the surface of the plastic. This residue can impact the effectiveness of the subsequent finishing steps, so thorough cleaning is essential to achieve a pristine surface. Once cleaned, the final stage involves coating or decorating the part, if necessary, based on its intended use.
While decoration may seem purely aesthetic, it plays a crucial role in making the part presentable, particularly when the final product will be visible in its application.
In industrial terminology, machining typically refers to the processes used to shape and form metals through various subtractive methods. This involves employing significant force to cut, trim, drill, and turn a workpiece to achieve a design that meets specific application or design requirements. While machining is commonly associated with metals, it is also applicable to plastic materials.
The need for plastic machining has grown as engineers design more innovative and complex shapes that cannot be easily mass-produced or require limited quantities with precise forms. For small components like gears, insulators, pulleys, and bushings, plastic machining often proves more cost-effective than molding or casting. This consideration is crucial when planning the production of plastic parts.
The techniques used in metal machining are also applied to plastics, including computer numerical control (CNC) machining and its various functions. Given that some plastics have comparable consistency to metals, processes such as drilling, sawing, turning, sanding, and brazing are employed based on the plastic’s hardness and strength. Plastic machining is frequently utilized for secondary processing of parts that have been molded, cast, or forged.
Similar to metal shaping, plastic machining encompasses various techniques, each involving the removal of material from a workpiece to achieve the desired shape. Typically, machining is performed to meet specific tolerances, ensuring that a plastic part fits seamlessly into a larger assembly. This aspect of the process demands precise tolerances and exceptional accuracy, skills that are mastered by trained plastic machinists.
Drilling is a prevalent technique in plastic machining, used to create holes of specific dimensions in a workpiece for various connectors. Drilling, whether performed on metal or plastic, generates significant heat due to friction. However, this effect is more pronounced in plastics. When drilling plastics, it's important to use large, polished flutes with a low helix angle of 14° to 17° to allow for efficient chip removal and prevent overheating and gumming. For high-speed drilling, flutes can have a standard spiral angle.
Effective plastic drilling requires rapid chip removal to avoid friction heat buildup from chips rubbing against the hole's walls. Specialized drills designed specifically for plastic should be used, as old or metal drills can cause binding. Coolants can help manage heat, necessitating frequent pauses to remove chips and dip the drill in the coolant.
Managing heat during plastic drilling is crucial. Optimal drill bit angles range from 9° to 18°, with point angles between 90° and 120°, facilitating efficient chip removal. Controlling factors like cutting speed, feed rate, tool design, tool materials, coolant types, and drill bit sharpness helps reduce heat and prevent damage, ensuring high-quality drilling.
To produce plastic products, various pieces must be joined together, often using methods like threading and tapping. These techniques involve cutting threads into plastic materials such as pipe ends, screws, and bolts.
Threading and tapping are accomplished with taps and dies. A tap creates the female portion of the thread, while a die forms the male portion. For threading plastic, die heads with chasers are recommended as they help remove burrs and ensure clean, smooth threads. Although they are often used to repair damaged threads, chasers are particularly effective for producing even threads in plastic.
As with drilling, using coolants during threading and tapping helps manage heat and prevents thread expansion. It is crucial to use tooling specifically designed for plastic to ensure sharpness and effectiveness, as tools used for other materials may not perform adequately.
Using a lathe for machining plastics follows the same principles as when working with wood or metals. The workpiece is firmly secured to the lathe, and material is removed through rotation and cutting. The lathe rotates the workpiece horizontally while cutting tools shape it to meet the desired specifications. This process yields parts with precise symmetry and tight tolerances.
Lathes are particularly effective for creating round shapes and turning plastics. To achieve various forms and designs, additional equipment can be attached to the lathe. As with other machining techniques, the cutting process generates chips that can clog tools and entangle around the workpiece. To manage this, coolants are used to help clear away chips and maintain smooth operation.
Milling plastics can be performed using both CNC mills and manual mills. During this process, the workpiece is securely fixed while a high-speed steel cutter removes material. CNC milling is often preferred for its precision and speed, as it can be programmed to achieve exact cuts. It is essential to take precautions to prevent chatter marks and movement of the workpiece on the table. Proper clamping is crucial; it must be firm enough to hold the workpiece in place without causing it to spin.
In addition to secure clamping, plastics milling often employs a technique known as climb milling. This method involves the cutter engaging the material at the top of the cut, which helps to reduce chip thickness and enhances the finish. Climb milling allows for a smooth, even surface finish and requires less power from the spindle due to the efficient removal of chips without recutting.
For roughing operations, rough end mills are used, while finish cuts are typically done with two or four-flute mills, depending on the material type and chip characteristics. End mills with rounded corners are often employed for cutting inside pockets to ensure that the final piece does not have sharp corners.
Sawing thick and heavy-duty plastic can generate friction but typically does not require coolant. Fine-toothed saw blades are recommended for this task. For band sawing, skip-tooth blades with four to six teeth per inch are ideal. The sawing machine should have a high-quality blade guide to ensure accurate, square cuts, and the plastic workpiece must be securely clamped to the worktable. Unlike drilling, sawing plastic allows for the use of maximum blade speeds and the full length of the blade. Fine-tooth saws with small teeth are effective for making precise cuts without damaging the material.
For intricate cuts, a table saw can be used. The workpiece should be firmly held and moved slowly toward the blade. To avoid melting the plastic, use a non-melt blade with evenly spaced teeth.
Often, sawing is a secondary finishing process used to trim plastic components formed by other methods. It is rarely performed manually and requires precise control to ensure smooth, even edges and exceptional tolerance.
In the sawing process, the thickness of the plastic affects the number of teeth per inch on the blade. Cutting speeds vary from 1000 ft/min to 5500 ft/min (300 m/min to 1700 m/min), with higher speeds used for thinner plastics. Most plastic machining companies use high-carbon steel blades and frequently employ air blasts to prevent chips from sticking to the blade.
The purpose of grinding is to shear material from a workpiece to achieve a specific surface finish. Water-based coolants are used to manage friction and prevent thermal degradation, which can occur as plastic is ground. These coolants help keep chips smaller and minimize thermal effects.
Grinding is a highly aggressive process and must be carefully controlled to avoid damaging the workpiece. High-quality grinding tools are essential, as grinding can cause rapid tool wear. Grinding forces are applied in small amounts using diamond or carbide grinding tools at appropriate feed rates and speeds. Tubes are positioned at the entrance and exit of the grinding wheel to reduce whip due to the high rotational speed and assist with workpiece alignment. The grinding speed varies depending on the type of stock and the amount of material being removed. The result of grinding is a smooth finish and exceptionally close tolerances.
Regardless of the hardness of a plastic, each type has unique characteristics that must be considered during machining. Proper clamping, holding, and securing of the workpiece are fundamental to avoid deflection away from the machining tool. Dull tools can deform the workpiece, making it crucial to maintain machining tools in peak condition, ensuring that only the cutting edge contacts the workpiece. Rubbing by machining tools creates friction, which can negatively impact the finish and quality of the workpiece.
Coolants are highly beneficial in plastic machining but must be applied correctly. Typically, coolants are sprayed onto the workpiece to keep it cool and prevent thermal expansion. Proper coolant use allows for higher cutting speeds and extends the life of machining tools. Water is preferred over oil as a coolant due to its superior heat removal rate. Controlling and preventing friction is essential for maintaining the quality of plastics, requiring meticulous care.
Although the processes used to machine plastics are similar to those for metals, plastics present unique challenges due to their sensitivity to various conditions, including weather, atmosphere, and environment. Achieving dimensional accuracy with plastics is challenging and often requires stress-relieving processes, with temperature control being a primary concern.
In addition to stability issues, there are safety concerns associated with plastic machining. Heating plastics can release harmful vapors, and plastic dust can cause eye irritation and respiratory issues. To address these concerns, plastic machining companies provide protective gear for their workers and implement measures for emergency care.
The key question now is which fabrication process should be selected for your design. This decision can be guided by evaluating the following specifications:
When selecting a fabrication process, it's crucial to consider the specific requirements and tolerance measurements for each part. These factors significantly influence the choice of fabrication method. Additionally, part geometry is a key consideration, as optimizing the design for manufacturing (DFM) may be necessary to achieve more cost-effective production. Careful attention to these details ensures that the chosen fabrication process aligns with the design needs and production goals.
Moreover, you need to consider what strains or extreme conditions your product will need to withstand before finalizing the manufacturing process. Along with these factors, you must also balance aesthetic and functional requirements with the overall value of the production process.
Another crucial specification is the cost per unit. The volume of parts you plan to produce is essential. Certain methods may involve higher initial costs for setup and tooling but result in lower costs per unit when producing in bulk.
Conversely, some processes suited for low volumes have minimal setup costs but incur a consistent cost per unit due to slower production rates, manual labor, and less automation. Additionally, consider your timeline for receiving the final products. Some methods can deliver initial parts within a day, while others, especially those for high volumes, may require several months for setup and tooling.

Once plastic products are used, they can be recycled not only to benefit the environment but also to lower energy use and production costs. Reclaimed plastics are frequently repurposed into items such as packaging materials, plastic lumber, furniture, and various composite goods. The recycling and reclamation processes involve multiple methods to transform post-consumer plastic into usable material. The initial step in this reclamation process is the Granules Manufacturing Process.
The initial phase in a standard plastic recycling process involves categorizing different types of resin and grouping them accordingly. Once sorted, the plastic items are shredded into particles of varying sizes, depending on the subsequent processing methods. These resin granules serve as the foundational material for manufacturing new products.
The next phase in the plastic recycling process is cleaning. Granulated resin typically requires washing before moving on to the following processing steps. This cleaning is performed either at ambient temperatures or at elevated heat levels. To ensure thorough cleanliness, disinfectants and detergents are often employed.
During the third stage, the cleaned plastic is sorted into reusable and non-reusable materials. This separation is based on the differing density levels of plastic base resin and contaminants. Techniques such as hydro-cyclone systems or water baths are used for this process. In a water bath, the denser resin will settle at the bottom, while lighter impurities rise to the surface.
Finally, once grinding, washing, and separation are finished, the reclaimed plastic is rinsed to remove any residual dirt or disinfectants from earlier stages. Melt filtering is a common post-reclamation step performed at a conversion facility. This process aims to further purify the material by eliminating any non-melting contaminants that may have persisted through the previous granulation, cleaning, and separation steps.
Plastic fabrication offers exceptional versatility and numerous advantages compared to other manufacturing methods like metalworking. It is a dependable, efficient, and relatively straightforward process. Some of its key benefits include:
Plastic boasts a lower melting point compared to many other materials, which, combined with its excellent malleability, facilitates the creation of intricate geometries with relative ease.
Plastic parts can be coated or colored prior to fabrication by mixing color additives directly with the pellets or granules. This pre-coloring process significantly reduces finishing efforts, especially beneficial in mass production scenarios.
Plastic molding and shaping require minimal time, which shortens the cycle time. Reduced cycle time leads to lower lead times and faster production rates.
Plastic has transformed the fabrication industry with its lightweight nature. Being lighter than metal, plastic often outperforms in various applications. This advantage is driving a shift across industries towards plastic fabrication.
Plastics generally exhibit greater resistance to chemical damage compared to metals. They are less susceptible to oxidation and reduction reactions, offering enhanced chemical resistance.
While plastic is often considered an ideal material for many fabrication needs, it does have its drawbacks. Like any material, plastic has its own set of disadvantages.
Plastics tend to have low resistance to high temperatures and can easily melt or deform when exposed to elevated heat levels.
Plastics generally lack resistance to corrosive substances and acidic environments. Exposure to such materials can significantly compromise their structural integrity.
While plastics are utilized for components requiring strength, they often fall short in providing the high structural strength needed for heavy machinery or building structures.
Many plastics are non-degradable and can take a long time to decompose in landfills. As the use of plastic products, especially packaging, increases, the growing volume of plastic waste poses a significant concern for landfill space.
Plastic fabrication has made a substantial impact across various industries. It plays a crucial role in diverse applications, including thermoplastics and thermosetting plastics used in building and construction projects like windows and doors, planting and storage tanks, piping systems, filtration setups, chemical feeders, ventilation systems, and chemical storage solutions. Each industry benefits from the versatility and adaptability of plastic fabrication in unique ways.
Plastics come in a variety of forms and materials, each suited to different applications. For example, polyurethane and polycarbonate are often used for windows and doors due to their durability.
