Polymer Holding

Polymer has manufactured close-tolerance plastic parts and assemblies for blue-chip customers with demanding applications worldwide.

In 1979, two brothers formed what is now Polymer Corporation to pioneer a unique Liquid Resin Casting process to meet the needs of Boston’s high-tech companies for low-volume, quick-turn, close-tolerance plastic parts. Polymer today has evolved from that small, family-owned business into a substantial company owned by management and Prospect Partners, a leading private equity firm that is backed by a premier group of major institutional investors (www.prospect-partners.com). Focused exclusively on manufacturing high-precision plastic parts and assemblies, in quantities ranging from less than a hundred to hundreds of thousands per year, they offer Liquid Resin Casting, injection molding, machining, rapid prototypes produced using leading-edge additive manufacturing technologies, and fully functional quick-turn ProtoParts.
