双合金双螺杆和机筒

具有优良的耐腐蚀、耐磨性和较高的工作温度

我公司在螺杆的顶部采用特殊的合金粉末喷涂焊接,针对不同功能的螺杆采用不同的合金和焊接方法

The bimetallic barrel for twin screw extruder is a kind of barrel spary a 1-3mm 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 high calcium carbonate powder PVC mixture to enhance the abrasion life.


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.
