Product Q&A

Q:What is the minimum order quantity (MOQ)?

The MOQ is 1 set.

Q:What is the lifespan of the screw and barrel?

Lifespan varies with formula and heat treatment. For 30phr nitriding, expect 3-5 years. Bimetallic screws and barrels have an extended lifespan.

Q:How can I ensure your quality?

We provide test reports for material, heat treatment, and tolerance before shipping. Our quality is trusted by many extruder and screw & barrel makers in Europe and Asia.

Q:Can I improve the current screw and barrel properties?

Yes, for unsatisfactory output or melt quality, our engineers can revise or redesign your screw and barrel. Customized solutions are available.

Q:What materials are available for customization?

Custom materials include 38crmoala, 40cr, SKD61, 31crmov9, D2, and Gr12MOV.
