We offer machining and finishing services to make tools from a variety of materials, and can produce 50 to 100,000+ finished parts in a wide variety of plastics. With advanced material verification and quality processes we can ensure your tools and parts exceed your expectations.

What is Injection Mold?

Plastic injection molding is by far the most common way to produce large volumes of finished plastic parts for every kind of commercial and industrial use. Molten resin is injected under high pressure into the cavity of a metal die and then rapidly cooled, forming a solid shape. A single cycle to make a finished part may take anywhere from a few seconds to minutes depending on part complexity and size.

Advantages Of Injection MoldInjection Molding
