Product Q&A

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

The MOQ is 1 set/pcs.

Q:What is the lead time for delivery?

Lead time varies by size and type. For nitriding single screw/barrel, it ranges from 40 to over 70 days depending on diameter. Bimetallic versions require an additional 5 days. Twin screws range from 35 to over 60 days.

Q:What is the expected 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: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 before shipping. We also provide test reports for material, heat treatment, and tolerance.
