What's New

Compounding Line from TPEI is Designed for Quick Cleanup and Concentrate Change

When Breen Color Concentrates, a major supplier of custom color concentrates to the plastics industry, wanted additional capacity, it chose the new state-of-the-art Quick Clean Color Change compounding line from Technical Process and Engineering, Inc. TPEI designed and fabricated the compounding line for quick changeover and cleanup of small lot runs of concentrates that allows for quick cleanup and concentrate change in as little as thirty minutes. The line was shipped as a turnkey system and included the mezzanine, feeders, pre-mixer, interconnecting wiring and pelletizing system permitting the full integration of space, features and footprint all focused on Breen's quality service.
