All component materials are supplied by domestic first-line brands or European professional materials suppliers of twin-screw plastics machines. And check the twin screw extruder screw elements and metallography to ensure that the raw materials are safe and nothing wrong. 100% internal spline is checked with a spline plug gauge to ensure the interchangeability of components. All of our twin screw extruder elements are finished by CNC grinding after heat treatment. The surface roughness of this series is less than Ra0.8, which completely eliminates the influence of heat treatment deformation on the quality of components. Powder high-speed steel is processed by the European HIP process and treated strictly according to the heat treatment process each other, the wear resistance and corrosion resistance of our twin screw extruder China elements are the same as those of foreign first-line brands. As a professional technical team of twin screw extruder screw elements, KY machinery can not only provide timely and accurate twin screw extruder screw elements sample surveying and mapping design, but also provide technical services in twin screw element assembly.
