Prototype Injection Molding


Prototype plastic injection molds produce real injection molded parts for functional testing. They can also serve as bridge tooling to fill the manufacturing gap for production tooling.

Prototype molding is built quickly; the part has the shape and functionality a plastic prototype part would need for testing form, fit and function, but may not have fine details like color preference or surface finish. Prototype molds are warrantied for up to 10,000 cycles.

The ICOMold Prototype Mold Difference

 Injection molding colored plastic prototypesWhen it comes to prototype injection molding, a manufacturing industry trend is to use 3D printed parts for prototypes, test, then skip right to production molds. This method can produce less than optimal results because of the limitations of 3D printing, such as the limited plastic materials available compared to injection molding. Injection molded plastic prototypes, on the other hand, are in many cases absolutely necessary for proper testing of plastic material characteristics.

  • No Size Limitations
  • Any Commercially Available Material and Surface Finish

Why Injection Molded Prototypes?  

Prototype production is a necessary part of the injection molding industry because the costs associated with producing a prototype are significantly less than going straight to large scale production. It’s a tried and true method for ensuring your mold is accurately designed and produced prior to reproducing thousands if not millions of copies.  Nothing can compare to holding a close to final version of your product to ensure what you have designed and engineered is indeed what you will get in the end.

Rapid Prototype Mold Testing Saves Time and Money

A prototype mold can produce the same type of parts as a production mold, but it is only warrantied for 10,000 parts due to its tooling materials. This is why the cost of a prototype mold is less than a production mold. 

ICOMold Fast Prototype Molds are What You Need

ICOMold can quickly build prototype molds by using S50C or P20 soft tool steel.

Design modifications with ICOMold couldn’t be easier. Working with your revised file, we can typically rework our steel molds within hours.

We assign a dedicated project manager and engineer for your injection molding projects. Please check out ICOMold’s Online Project Management System.
