Bimetallic Alloy Screw Barrel

Product Introduction:

The effective service life of Jed double alloy screw barrle is greatly improved than that of ordinary nitriding cylinder. For the processing of engineering plastics, fluorine plastics, polysulfone, PPO special type of plastics, the advantage of bimetal is particularly obvious.

Special alloy powder is used for spray welding of bimetallic single and twin screws in the screw edge part. Different alloys and spray welding methods can be used for different studious screws. For the single screw barrel through the inner hole centrifugal casting, for the taper double barrel outlet wear parts of imported alloy steel, after special treatment, can effectively improve the wear resistance of the barrel, improve the service life.

Centrifugal casting of double metal in the inner hole of the barrel has the advantages of wear resistance, corrosion resistance, high temperature resistance and high pressure resistance.

Zhoushan Jed Machinery Co., LTD. Main products are precision screw barrel (nitriding screw barrel, double alloy screw barrel, stainless steel screw barrel, fully hardened screw barrel, high-speed tool steel screw barrel), injection molding machine screw barrel, extruder screw barrel, blow molding machine screw barrel, chemical fiber screw barrel, single screw barrel, parallel twin screw barrel, conical twin screw barrel, Screw pipe accessories; Product selection 38CrMoALA; SACM645 ; SKD11; SKD61; 9Cr18MoV materials, after conditioning, molding, the surface can be nitriding, hard chrome plating, spray welding carbide and other processes. The product has the advantages of high wear resistance, corrosion resistance and long service life. It can replace imported products.
