Product Details
Bimetal machine is to cast a layer of 2-5mm wear-resistant, corrosion-resistant and high temperature resistant alloy on the inner wall of the machine. Its effective service life is greatly improved compared with that of ordinary nitriding machine. The superiority of bimetal is especially obvious for processing engineering plastics, fluoroplastics, polylotion, PPO special types of plastics, etc. The company's production of single-screw bimetallic screw, using special alloy powder in the screw edge part of the spray welding alloy, can be for different functions of the screw using different alloy welding methods.

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 a 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 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).
50–60 days for nitrided conical twin-screw and barrel assemblies (Φ92/188–Φ110/220).
Over 60 days for nitriding conical twin-screw and barrel assemblies (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 depending on the formula and heat treatment. For 30 phr nitriding, expect 3–5 years.
Bimetallic screws and barrels have an extended lifespan.
4. How to submit an inquiry?
Feel free to contact us via email or WhatsApp. Visiting our factory is recommended.
5. How can we ensure your quality?
