This screw and barrel are generally used on all kinds of plastic machines, such as injection molding machines or extruders etc

SL brings in the most advanced Germany meltallizing jet welding and The centrifugal casting technology and equipments, and jet American alloy powder directly and fully to the surface of the screw and inner hole of barrel. The depth of the bimetallic can be reach more than 1.5mm and the surface of the bimetallic density will be 98-99.5, and during the processing, the screw temperature can be controlled under the low one to avoide hot deformation and hot brittleness. The alloy powder adhensive strength is more than 10, 000 PSI. Therefore, our bimetallic screw has features of anti-abrasion, anti-corrosion and anti-broken. It can provide the best service for the engineer plastic factory.

The bimetallic barrel cylinder is a kind of cylinder with more than 1.5mm an alloyof anti-abrasion, erosion proof and high temperature cast on the inner wall on it. Contrast to common nitrating barrel, its useful service life is greatly improved.

Product Superiority: Wear-proof, corrosion-proof, adding lees than 30% glass fiber and Renewable materials is specially good plastic range applicable: PA, PPT, ABS, PC, PA ETC. The recommended plastic products: PA, ABC, PC.
