Bimetallic blow molding machine screw and barrel for HDPE
Manufacturer for blow molding machine screw and barrel
Bimetallic screw: Base material 38CrMoAlA, sprayed alloy powder on the screw flight, prolong life of screw.
Bimetallic barrel: Base material 40Cr, casted a 2-5mm wear resistant and corrosion resistant bimetallic layer
on the barrel inner wall, so it has much longer using life than nitrided barrel.
We can manufacture all types of screws and barrels according to clients' requirement.
