Material
High quality Alloy steel
1) Carbide+Alloy
2) WCCo
3) Cr C-Ni Cr
4) 9Cr18MoV
Introduce for bimetallic screw and barrel:
screw and barrel diameter: Φ15~Φ300
For bimetallic barrel, we use Centrifugal casting technology, it can increaseing the useing life of the barrel. For bimetallic barrel, it contain the tungsten30%~50%.
Introduce for Stainless steel screw
The material we use 9Cr18MoV, after treatment, quenching then for using together with bimetallic barrel. Widely apply to processing PMMA, PC etc. To be made of plastics products.
Technical Parameter
Depth of Bimetallic：2.0~3.0mm
Hardness of Bimetallic: HRC59°~65°
Roughness of the surface: Ra 0.4um
Straightness of the screw/barrel:0.015mm
This types screw and barrel apply to: normal plastic, PP, PE, ABS, AS, PS, etc.
Heat treatment:
Nitriding treatment
Special Equipment
Centrifugal casting for barrel
High speed Quenching
