Wepco Plastics Inc.

Wepco Plastics Inc. Wepco Plastics is a family owned company offering American made parts. Wepco Plastics started in Wally Parmelee’s basement in the early 1980’s.

We specialize in 3D prototyping, rapid prototype aluminum tooling, and short to medium run plastic injection molding with 4 axis aerospace machining, fixturing, and secondaries. Demand for his molds and his desire to expand into injection molding quickly made it apparent that larger space was required. The need for expansion happened again just a few years later and Wepco moved to its current 10,0

00 square foot location in Middlefield, CT. Wepco is the truly the quintessential family owned and run business. In addition to Wally’s son David, who took over as president in 2016, his daughter Cara works for the company. This familial environment has helped to forge a culture at Wepco that centers on taking care of our customers. We specialize in lower volume plastic injection molded parts and rapid aluminum tooling. Our promise is that we will continue to perfect our craft by investing in training and equipment so that we can meet all of your mold building and injection molding needs. From concept and design, through mold manufacturing and part production, we are our customer’s preferred one-stop option for quality plastic parts.
