Barrel Technology – Over 20 Years of Expertise

We have been developing and manufacturing extruder barrels for over two decades. Our barrel systems are now mature and widely used in twin-screw extruders from renowned domestic and international brands such as Coperion, Berstorff, Leistritz, JSW, Toshiba, STEER, and Ikegai.

According to customer requirements, we recommend suitable materials tailored to specific working conditions.
