 FAQ:

 Q1: What's injection screw barrel?

A: Injection Screw barrel is the major and most important part for plastic injection molding machines. It provides the plasticization of plastic and eject process of plastic into moulds.

Q2: Who do you supply injection screw barrel for?

A: With our 10 years' development, we have now established stable business with lots of injection molding machine manufacturers like ChenHsong and Yizumi. For most of Chinese based manufacturers, we can suit for their machine. Also we have made customerized screw barrel for some foreign brand like Nessei, JSW and Toshiba brand.  

Q3: Can you process with customerized screw barrel according to our own drawing?

A: Yes, we do process screw barrel according to customerized design drawing.
