Hot Runner System

Mold-Masters Co-injection hot runner systems (formerly Kortec) utilizes industry leading technology to convert mono-layer components to multi-layer while maintaining your existing part quality and productivity levels. The core layer can be either a high performance barrier to improve part performance or a post consumer recycled (PCR) resin to lower part costs. Ideal for a wide range of packaging, medical, consumer goods and automotive applications.
