We know the key to producing identical parts is monitoring and controlling a proven, reliable process.

It's hard to tell our parts apart. It's easy to see why. Our "Visual Factory" approach improves communication, part quality, and response times. A central material handling system reduces changeover time, and three 45-foot, two-color display boards display real-time process data from our MATTEC process monitoring system. These boards color code the status of 13 critical parameters of the molding process for everyone to see, enabling our well-trained employees to work together to solve problems, improve productivity, increase production, and reduce operating costs.

Pentair Kaizen Event
Pentair and EPC wanted to develop a system to stabilize Pentair's inventory levels so Pentair would not need to store excess inventory or lose production time when inventory levels came up short.


Engineered Plastics Internal Innovation
EPC was not satisfied with the traditional method they had been using to install brass inserts in their injection molded parts.
