螺纹元件
Screw elements
螺纹元件是双螺杆挤出机的重要工作部件之一，其品质直接影响了塑料颗粒的质量。螺纹套主要是用于喂入与传送物料，而物料的塑化、混合和分散是靠捏合块来实现。对不同的物料，可以通过改变螺纹元件的组合，来调节混合、剪切、分散和着色的效果。
公司拥有：加工中心、螺纹磨、专用数控锯床、磨床等设备，能够自主加工生产出多品种的耐磨、耐腐与高精度的螺纹元件。
The precise screw element is very important components for the quality of plastic.Our precise screw elements made by CNC tools provide SAT better intermeshing and self-wiping performance which ensures the entire processing no dead corner and better control in RTD(residence time distribution).
Except various screw geometry,we supply several materials of screw elements for different processing purpcse.we also can configure different screw materials in different processing section.
