Product Q&A

Q:What is the minimum order quantity?

1 piece is available.

Q:What is the lead time for delivery?

Lead time varies by size and type: 40-50 days for small nitriding single screws, 50-70+ days for larger sizes, 45-60+ days for parallel twin screws, and 35-60+ days for conical twin screws. Bimetallic screws require an additional 5 days.

Q:How long is the lifespan of the screw and barrel?

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

Q:How do you ensure product quality?

We partner with major manufacturers in Europe and Asia. Before shipping, we provide test reports for material, heat treatment, and tolerance.

Q:Can you improve existing screw and barrel properties?

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