Active Molding delivers precision micro-molding solutions from our USA facility. With 20+ years of expertise, we manufacture high-tolerance plastic components from micro-parts under 0.1 grams to production runs up to 25 oz. Our in-house tooling and vertically integrated operations ensure quality control at every step.
At Active Molding, we specialize in custom precision injection molding, in-house tooling, and secondary machining. Our precision injection molding machines range from 28 to 200-ton capacity and produce high-precision micro-parts weighing less than 1/10th gram, to parts as large as 25 oz.
With over 20 years of experience in the custom plastic injection molding industry, our molds are designed, constructed, and maintained internally at our in-house tooling facility. We also partner with outside tooling sources for larger projects that have industry-leading experience and facilities.
Our employees take great pride in caring for your molds, the equipment and ultimately the end product. We offer value added secondary services including machining, prototyping, and light assembly. Our goal is to achieve maximum efficiency and to continually improve our operations, which provides us with a competitive advantage that benefits our clients.


From concept to production, we deliver precision micro-molding solutions for the world's most demanding applications. 100% USA manufacturing with tolerances measured in microns.
