Twin Screw Element For Plastic Masterbetch Machine Production Line
1. Descriptions
All component materials are supplied by domestic first-line brands or European professional materials suppliers of twin-screw plastics machines. And check the extruder screw elements and metallography to ensure that the raw materials are e 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.
