FAQ 

1. How about the MOQ:

1 piece is available.

2. What is the lead time?

Lead time varies depending 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 assemblies (Φ180–Φ250).

Over 70 days for nitriding single screw and barrel (Φ250–Φ500).

45–50 days for nitriding parallel twin-screw and barrel assemblies (Φ45–Φ90).

50–60 days for nitriding parallel twin-screw and barrel assemblies (Φ90–Φ135).

Over 60 days for nitriding parallel twin-screw and barrel assemblies (Φ135–Φ350).

35-45 days for nitrided conical twin screw and barrel (Φ25/50–Φ80/156).
