Our product range

Standard parallel twin screw barrel

Our standard parallel twin screw barrel is a versatile solution suitable for a wide range of applications. It excels in processing general-purpose materials and provides consistent and reliable extrusion results for industries such as plastics, rubber, and more.


Co-rotating parallel twin screw barrel

The co-rotating parallel twin screw barrel is designed for simultaneous rotation of both screws in the same direction. This configuration enables efficient mixing, compounding, and excellent self-cleaning properties, making it ideal for compounding and masterbatch production.


Counter-rotating parallel twin screw barrel

In contrast to the co-rotating design, the counter-rotating parallel twin screw barrel has screws that rotate in opposite directions. This design offers enhanced shear and mixing capabilities, making it suitable for processing materials with different viscosities and complex formulations.


High-wear-resistant parallel twin screw barrel

When processing abrasive materials or harsh environments, our high-wear-resistant parallel twin screw barrel is the ideal solution. This product is engineered with wear-resistant materials and coatings, ensuring extended service life and reduced maintenance costs.


Customized parallel twin screw barrel

We offer customized solutions tailored to your specific needs. Our engineering team will collaborate closely with you to develop a parallel twin screw barrel that perfectly aligns with your extrusion process goals.
