Medical Device Prototyping Services & Solutions

Medical device prototyping is the process of creating an early physical model of a medical device component to evaluate its design, fit, and function before committing to full production tooling. Using materials like ABS, HDPE, or PETG, manufacturers can test form, identify design issues, and make iterative improvements quickly and cost-effectively, reducing risk and development time significantly.

Building a medical device prototype typically involves defining design specifications, selecting appropriate plastic materials, creating low-cost tooling (such as a CNC-milled wood master pattern), and then thermoforming or fabricating the part to those specifications. At Hill Plastics, we use SolidWorks for CAD design and CNC interface, enabling accurate master pattern creation in just a few weeks depending on design complexity.

Common materials include ABS for its impact resistance and machinability, HDPE for chemical resistance and durability, PETG for clarity and ease of forming, and High-Temperature ABS for applications involving heat sterilization. Hill Plastics evaluates each project's requirements—including chemical exposure, durability, and tensile strength—to recommend the most appropriate material for your specific medical device application.

With Hill Plastics' low-cost wood tooling approach, a CNC-milled master pattern can typically be completed within a few weeks depending on the complexity of the design. Prototype parts can follow shortly after the pattern is mounted on a mold base. This rapid timeline helps medical device development teams stay on schedule without waiting months for traditional hard tooling.

Prototypes are made using low-cost tooling—typically wood or polyurethane—for fast, affordable design validation. Production parts use aluminum molds machined from the approved master pattern, offering greater durability, repeatability, and surface consistency for high-volume runs. Hill Plastics manages both stages seamlessly, ensuring a smooth transition from prototype approval to full-scale production without redesign delays.

Yes. Hill Plastics is equipped for every stage of production, from a single prototype to high-volume manufacturing runs of thousands of parts. The company operates a 4'x7' rotary thermoforming machine with cycle times 2.5 times faster than standard equipment, eight thermoforming machines of varying sizes, and over 20,000 square feet of facility space in Lewisville, TX.

Absolutely. Brad Hill and Cody Hill from the sales and engineering team provide direct assistance with product design, tooling design, and material selection. They evaluate your application requirements—including durability, chemical resistance, and environmental factors—and guide you from initial concept through to a finished, production-ready part, ensuring cost-effective decisions at every stage.

Hill Plastics produces a wide range of custom plastic components for the medical industry, including custom enclosures, housings, material handling trays, OEM parts, and fabricated assemblies. Using thermoforming, vacuum forming, CNC trimming, and precision fabrication, the team can produce components to exact drawing specifications with clean edges, accurate dimensions, and repeatable quality suited to medical-grade standards.
