How to Build a Medical Device Prototype
At Zigitech, we rely on several precision machining techniques to build our clients’ medical prototypes, including:
CNC machining. Our precision CNC machining capabilities, including milling, turning, EDM, wire EDM, and surface grinding, allow us to create complex 3D shapes, geometries, features, and surfaces on metal (including aluminum) and plastic substrates. The machining process produces tight tolerance medical device prototypes and products accurately and repeatedly.
Clear acrylic machining and polishing. Surface finishing operations, such as clear acrylic machining and polishing, alter the surface of the prototype or product to provide a distinct or desired aesthetic or function. These techniques can change the appearance and add other characteristics to the part, such as greater corrosion resistance or conductivity. For acrylic specifically, the machining and polishing operations facilitate the production of products with high clarity and precision, such as lenses and prisms.
Aluminum machining. Aluminum is a low-density, high-strength substance. Machining and polishing the material allows manufacturers to produce high quality, close tolerances, products, and prototypes.
Vacuum casting. Vacuum casting is ideal for creating rigid and flexible parts and prototypes. At Zigitech, we offer hundreds of casting polymers and a variety of color options to select from, as well as turnaround times of 15 days or less for up to 20 parts (depending on part design and volume). Compared to other prototyping methods, such as injection molding, this process provides better surface finishes and is more affordable as the molds are less expensive and more durable.
Reaction injection molding (RIM). Reaction injection molding produces strong, lightweight parts and prototypes. Compared to other injection molding methods, the process allows for more complex and intricate part geometries at a low cost per part. Additionally, in general, the injection molding process enables repeatable, high volume production (into the millions).
