Chapter Two – How are Carrying Cases Made?

The design and manufacturing of a carrying case depend on its intended use. Standard off-the-shelf cases, available in department stores and online, differ significantly from custom cases designed for specialized applications, such as carrying scientific instruments and delicate equipment.

Carrying cases can be constructed from a range of materials, including aluminum, plastic, wood, sturdy fabrics, lightweight metals, and leather. The key requirements for any carrying case are durability, flexibility, and ease of portability. Some cases use a combination of materials to improve strength and longevity.

Making Carrying Cases

The construction of a carrying case is tailored to its intended use. For instance, cases designed for air travel must adhere to specific standards concerning materials, thickness, repairability, and latches. Many manufacturers design cases that exceed these basic requirements to ensure enhanced protection and durability.

Carrying Case Materials

Carrying cases are constructed from a variety of materials, including lightweight metals and heavy-duty fabrics such as nylon and neoprene rubber. Plastic cases are often created through blow or rotary molding and may feature cloth or foam padding liners.

Plastic Cases

Among the various materials used for carrying cases—such as wood, aluminum, fabric, and metals—plastic is the most prevalent due to its ease of formability, availability, and durability. Molded plastic carrying cases are the most common on the market, available in sizes ranging from small, hand-held cases to large, wheeled cases for shipping and transporting substantial equipment.

Plastic's versatility allows designers to shape, configure, and engineer cases to meet various conditions, applications, and aesthetic requirements. This adaptability makes plastic an ideal material for carrying cases that must be rugged and durable enough to withstand demanding environments.

The strength of a carrying case largely depends on the type of plastic used. Plastics, derived from petroleum, are processed into small pellets known as resin or into powder form. These materials are melted before being molded and shaped. The term "plastic" encompasses a range of materials with varying densities and molecular structures. For carrying cases, commonly used plastics include high-density polyethylene (HDPE), fiberglass-reinforced polyester (FRP), carbon fiber, rotationally molded polyethylene, and linear low-density polyethylene (LLDPE).

Blow Molded Plastic Cases

In the blow molding process for plastic cases, plastic is blown into a metal mold. The plastic is forced to evenly cover the surface of the mold as air fills the center of the molten plastic. The final case is uniformly shaped without seams or gaps. Plastic case manufacturers use thermoplastic for its durability, pliability, flexibility, and longevity.

Thermoforming Process

The thermoforming process involves heating plastic sheets and using heat, vacuum, or pressure to shape them into three-dimensional objects. Plastic sheets are fed from rolls into a molding machine where they are heated until they become pliable, but not melted. Molds are then pressed against the heated plastic sheets to create the shape of the carrying cases. After molding, the cases are removed, trimmed, inspected, and prepared for further processing.

Thermoforming can be classified into three types: mechanical, vacuum, and pressure. In vacuum thermoforming, negative pressure pulls the preheated sheet into the mold cavity. Pressure thermoforming, on the other hand, uses positive pressure to push the plastic into the mold. Mechanical thermoforming involves the use of both positive and negative molds that are brought together over the preheated plastic sheet.

Injection Molding

Molds used in injection molding are typically crafted from steel to ensure durability and precision for repeated use. In the injection molding process, material is fed into a barrel where it is heated and melted by a helical screw as it progresses along the barrel. The molten plastic is then injected into the mold, as depicted below. Two-shot molding allows for the use of different materials to combine colors and features in the final case. However, injection molding is generally limited to producing cases of certain sizes.

Rotational Molding

Rotational molding is utilized to create very large cases with precise tolerances. The process starts with a mold, typically several feet wide, long, and high. Raw plastic resin is placed into a closed mold that shapes the top and bottom of the case.

The mold is mounted on a frame that can rotate along multiple axes. This assembly is then heated in a chamber until the plastic resin melts. As the frame rotates, the melting resin evenly coats all sections of the mold, forming a consistent layer.

This technique allows for the production of various case designs, including those with double-entry, lift-off, and hinged lids. Most cases produced by rotational molding are custom or special orders. The entire process is illustrated in the image below.

Aluminum Cases

The manufacturing process for aluminum cases resembles thermoforming. It begins with flat aluminum sheets, which are either rolled or extruded to form the case's exterior. These textured aluminum sheets are then bent, shaped, and formed to create the top and bottom parts of the case. A frame is added around the edges of the top and bottom to ensure uniform proportions and a tight seal when the case is closed.

Handles, hinges, and corners are either riveted or welded to ensure strong, secure connections. For medium to large cases, wheels are often included to enhance portability and ease of handling. The primary goal of aluminum carrying cases is to ensure they can endure harsh and demanding conditions.

Neoprene Cases

Neoprene, also known as polychloroprene rubber, is a highly durable, non-conductive, and waterproof material. Its thickness and flexible, cushioned surface make it an excellent choice for protection against punctures, weather conditions, and various types of wear and tear.

Available in various shapes, colors, and sizes, these cases are known for their exceptional durability. They offer tear resistance and retain their shape under diverse conditions, even after years of use.

Leather Cases

Leather carrying cases differ based on the grade of leather used. Full-grain leather, which is the hide of an animal after the hair has been removed, maintains its natural texture and durability without any alterations. Although full-grain leather cases are highly durable, they are also more expensive. In contrast, lower-grade leathers are more affordable but offer less durability.

Wood Cases

Wooden carrying cases are crafted from durable woods such as pine, cherry, birch, or mahogany. They are known for their sturdiness and reusability. The interiors of these cases can be lined with wood, plastic, foam, or fabric, while the exteriors are often finished with leather, plastic veneer, or fabric for added protection and aesthetic appeal.

Carrying Case Design

Designing a carrying case is tailored to meet the specific needs of the customer. Manufacturers work closely with clients to develop prototypes or proposed solutions until the final design aligns with the customer’s requirements. Even seemingly minor details—such as handles, types of hinges, locking mechanisms, material durability, and other small components—are crucial in the design process. Attention to these details is essential for ensuring that the carrying case is both functional and durable.

American Transportation Association (ATA) cases are subject to rigorous design standards. To comply with ATA requirements, these cases must be vibration and shock resistant and can be constructed from various materials, including wood with a plastic veneer, plastic board, aluminum, and certain sheet metals. Handles and latches are often recessed to protect them from damage. The ATA provides a set of standards that determine a case’s classification and durability, ensuring that it meets the necessary performance criteria.
