Injection Molding Processes
Make the move from prototyping to on-demand manufacturing for affordable, high-quality molded parts within days. Better yet, your prototyping tool is free once you shift to an on-demand manufacturing tool. Working with a single supplier that provides free design consultation services also massively speeds up the manufacturing process, allowing for greater supply chain flexibility, more consistent parts, and making qualification a breeze.
Plastic Injection Molding
Plastic injection molding is a manufacturing process where resin in a barrel is heated to a molten state, then shot into a mold to form a final production-grade thermoplastic part.
Liquid Silicone Rubber Molding
Liquid silicone rubber molding is a thermoset process that mixes a two-component compound together, which is then heat cured in the mold with a platinum catalyst to produce a final part.
Overmolding & Insert Molding
Overmolding and insert molding are two-part injection molding processes where one material is overlaid onto a second substrate part or metal insert to create a single component.
Consistency and Quality
Tooling Options and Quality Reporting
We have two unique offers that meet your needs wherever you are in the product lifecycle. Our prototype molding process helps you cut product development cycles by weeks—sometimes months—and bridge to production with injection-molded parts within days. Our On-demand Manufacturing process helps you qualify parts quickly and seamlessly transition into production with scientific molding, critical-to-quality FAI and capability studies completed on automated CMM machines, and a full suite of secondary operations to make sure that your end-use production parts show up as expected.
I need to validate my design at Protolabs speeds. I need the flexibility to economically iterate before production.

Why Choose Protolabs for Injection Molding?
“It has been very enlightening to us here at HP that we are able to get parts so rapidly out of the actual materials that we’re going to use in the final production.“
