Protomold Injection Molding Service

Proto Labs offers customers fast and affordable parts based on supplied 3D CAD models. The Protomold process uses proprietary software that provides an unprecedented degree of standardization and automation. The result is injection-molded parts delivered faster and more economical than anyone else in the world.
As long as your part has a geometry that can be machined, we can injection mold it and in less time than other molders. Protomold works with advanced aluminum alloy molds and precise, high-speed CNC machining to eliminate the costly and time-consuming custom engineering that normally goes into the development of injection-mold tooling. We also support an ever-increasing degree of part size and complexity including many types of undercuts, tall/thin ribs or bosses, off-axis features and more.

Prototyping. Rapid prototyping processes like stereolithography (SLA), fused deposition modeling (FDM) and selective laser sintering (SLS) are fine for testing form and fit, but they are no substitute for testing with real injection-molded parts. With Protomold, you’re able to get injection-molded parts very quickly so you can begin functional testing before going to production.
Tooling. When your production tooling won’t be ready for another three or four months, bridge tooling is a great way to make a run of parts for pilot production or market testing. Bridge tooling through Protomold is ready to go with no additional cost or delay.
Production. If your volume requirements don’t justify expensive steel production tooling, Protomold can supply production parts to meet your full requirements. Multi-cavity aluminum molds can be very cost effective, and Protomold will ensure that the tools last for the life of your project.

When you’re ready to upload your 3D CAD model, our automated ProtoQuote interactive quoting system offers the ability to select the number of cavities, surface finish, selected resin and delivery schedule. Within hours, you’ll receive an interactive quote with moldability analysis and pricing information. Our proprietary software examines your model for potential problems and identifies issues — such as thick walls, sharp corners, undercuts and more — which could impact the manufacturability of your part. When you’re satisfied with the design and price of the part, you can place an order online 24/7.
