Product Q&A

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

The MOQ is 1 set.

Q:What is the lead time for delivery?

Lead time varies by size and type. For nitriding single screws, it ranges from 40 to over 70 days. For parallel twin screws, it is 45-60 days. For conical twin screws, it is 35-60 days. Bimetallic versions require an additional 5 days.

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

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

Q:Can you customize the screw and barrel design?

Yes, we offer engineering-led customization. We can revise or redesign screws and barrels to improve output or melt quality based on your specific raw materials and production requirements.

Q:How do you ensure product quality?

We perform 100% inspection of hardness, concentricity, and dimensional tolerance. We also provide test reports for material, heat treatment, and tolerance before shipping.
