双合金单螺杆和机筒

筒内壁喷涂2-5mm厚的合金涂层,具有优良的耐腐蚀、耐磨性和高工作温度

与普通渗氮管相比,其使用寿命大大提高


The bimetallic barrel for single screw extruder is a kind of barrel spray 2-5mm thick alloy coat on the barrel inner wall which has excellent corrosion resistance, abrasion resistance and high working temperature. And its useful service life is greatly improved contrast to common nitrided barrel. Bimetal has more abvious advantages when processing special plastics to enhance the abrasion life, such as engineering plastics, fluoride plastics, PPO etc.


Our company use special alloy powders being sprayed and welded on the top of screw flights, and use different alloys and welding methods for the screw of different functions.
