FAQ
1. 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.
