Manufacturing a custom carrying case requires careful consideration of the materials used to construct it. Each material offers different strengths, protective qualities, and design flexibility.
In this guide, we explore three primary material groups commonly used in case manufacturing:
Polymers, valued for their durability, impact resistance, and lightweight properties.
Textiles, designed for flexibility, portability, and user comfort.
Metals, used when maximum strength, durability, and environmental resistance are required.
Understanding the characteristics of these materials allows device manufacturers to choose solutions that align with both technical requirements and product positioning.
Selecting the right materials for a medical device carrying case is essential for protecting sensitive equipment while maintaining usability, durability, and brand quality.
At Shell-Case, we understand that your devices represent the result of extensive research, innovation, and engineering. A well-designed carrying case does more than protect your device. It reinforces reliability, supports compliance requirements, and reflects the quality of your brand.
Our Material Selection Guide for Case Manufacturing helps medical device manufacturers understand the primary materials used in custom carrying cases and how each material contributes to performance, portability, and protection.

The materials used in carrying cases directly affect protection levels, product weight, manufacturability, and overall user experience. The three main material categories used in medical device case manufacturing include polymers, textiles, and metals.
Polymers are among the most widely used materials in custom carrying case manufacturing. Materials such as polycarbonate, ABS, polypropylene, polyethylene, and nylon provide a balance of durability, flexibility, and cost efficiency.
These materials offer strong impact resistance, lightweight construction, and excellent cleanability, making them well suited for portable medical devices and diagnostic equipment. Polymers can also be easily molded and customized, allowing manufacturers to incorporate brand colors, textures, and ergonomic design features.
Polymer-based cases are commonly used to protect devices that must withstand frequent transportation, environmental exposure, and everyday handling while maintaining reliable protection.
Textile materials provide a flexible and lightweight alternative for carrying cases designed for portability and user comfort. Materials such as polyester, nylon, cotton, polypropylene, and linen offer breathable, adaptable solutions that can be combined with internal protective structures such as EVA or foam.
Textile cases are particularly suitable for devices that are frequently carried by clinicians, technicians, or patients. Their lightweight construction improves mobility, while their flexibility allows for convenient storage compartments and ergonomic designs.
Because textile solutions typically require less production tooling, they can also allow for faster project timelines and adaptable case dimensions.
Metal materials provide exceptional strength and durability for carrying cases that require maximum structural protection. Common metals used in case manufacturing include aluminum, steel, zinc, brass, and magnesium.
These materials offer excellent resistance to environmental conditions and can support specialized requirements such as autoclave sterilization, electromagnetic shielding, and extreme durability. Metal components are also often used for structural elements such as handles, hinges, or strap connectors in high-performance cases.
Metal cases are typically selected for high-value medical equipment or devices that operate in demanding environments where protection and reliability are critical.
Choosing the right material for a custom carrying case involves balancing practical requirements with the broader goals of your product.
Manufacturers should evaluate several key considerations when selecting materials.
Protection and durability
The case must protect sensitive equipment from impacts, environmental conditions, and repeated use.
Compliance and standards
Material selection should support relevant regulatory and manufacturing standards, including ISO 13485 and other applicable requirements.
Manufacturability and scalability
Different materials influence production processes, tooling requirements, and long-term manufacturing efficiency.
By carefully evaluating these factors, manufacturers can select materials that not only protect their device but also support usability, reliability, and product presentation.
