The advantage of bimetallic screw: strong abration resistance, good for the 30% glass fiber and reworked materials.
Skin Characteristics.
1. Super hard alloy of high density, low porosity and high hardness.
2. Uniformity heating of power and low strength pressure.
3. With high corrosion resistance, high wear resistance and high temperature resistance properties.
4. Increasing of adhensive force with coating thickness

The bimetallic barrel for single screw is a kind of barrel moulding 2-5mm-thick alloy coat on the barrel inner wall which has excellent corroion resistance, abrasion resistance and high working temperatre. And its useful service life is greatly improved contrast to the common nitided barrel. Bimetallic has more obvious advantages when processing special plastic to enhance the abrasion life, such as engineering plastics, fluorine plastics, PPO, and tec.
