Injection Molding

From insert molding to over-molding, we specialize in custom injection molding for high-grade thermoplastics.  

Insert molding

Strong prototypes and production parts

Over-molding

High-quality, low volume process for test runs

Have a product design that requires a fully custom mold? Our Nissei Co-Injection injection-molding machine is up for the task. 

We use only virgin thermoplastic resins sourced in the United States to ensure quality. That high-grade input allows us to get high-performance output on every custom mold — single, multi-cavity, and family.

We can also adapt to special requests — from custom sourcing and matching of most plastic materials to 200-400 ton press availability. 

Those same standards of quality and extreme flexibility carry over to our customer service. Your dedicated product specialist stays with you throughout the process, so you never have to re-explain your situation or ask for a transfer. 

Our domestic partner network and international product options guarantee you end up with the best possible custom mold using the materials that make the most sense for your application
