How about MOQ:1pcs is available.2. What is the lead time?Lead time varies based on size and bimetallic status.40-50 days for nitriding single screw and barrel (Φ20-Φ90)50-60 days for nitriding single screw and barrel (Φ90-Φ180)60-70 days for nitriding single screw and barrel (Φ180-Φ250).Over 70 days for nitriding single screw and barrel (Φ250-Φ500).45-50 days for nitriding parallel twin screw and barrel (Φ45-Φ90).50-60 days for nitriding parallel twin screw and barrel (Φ90-Φ135).Over 60 days for nitriding parallel twin screw and barrel (Φ135-Φ350).35-45 days for nitriding conical twin screw and barrel (Φ25/50-Φ80/156).50-60 days for nitriding conical twin screw and barrel (Φ92/188-Φ110/220).Over 60 days for nitriding conical twin screw and barrel (Φ115/230-Φ185/340).Bimetallic screw and barrel require an additional 5 days.3. What is the lifespan of the screw and barrel?Lifespan varies with formula and heat treatment. For 30phr nitriding, expect 3-5 years.Bimetallic screw and barrel have an extended lifespan.4. How to submit an inquiry?Feel free to contact via email or WhatsApp. Visiting our factory is recommended.5. How can we ensure your quality?We partner with many extruder and screw & barrel makers in Europe and Asia, all satisfied with our quality.Before shipping, we provide test reports for material, heat treatment, and tolerance.6. Can I improve the current screw and barrel properties?For unsatisfactory output or melt quality, our engineers can revise or redesign your screw and barrel.Customized solutions are available.
