(Same standard for Triple Screw Extruder, Twin Screw Extruder and Blend Reactor)
The screw of the Twin Screw Extruder is constructed modularly and composed of a core shaft and screw elements. The screw elements are combined specifically according to the requirements of different materials.
Screw elements and core shaft are manufactured with high precision especially at the intermeshing clearance, so that the cumulative tolerance of the combined screw can meet the requirements of our design. This is the main characteristic of our screw shaft. It is also the basic guarantee that our machine can meet and satisfy the requirements of customers.
Screw shaft elements have two categories: screw thread elements and kneading elements.
The keys to its high quality are its designed shape, material selection, and manufacturing technology.
To specially design screw thread elements and kneading elements according to different materials. What makes us special is that; the structure we designed is based on the characteristics of the polymeric material, and also we have been determined our design plan base on testing and application. These are all derived from the combination of our multi-specialty and also our own factory.
Our selection of materials is abided with the following 3D coordinate principle. As shown in the figure, we have optimized the wear resistance, corrosion resistance and cost, so that the cost for value is scientific and professional.
We especially pay attention to our heat treatment process and the results of components that we produced. As far as we are concerned, these are potential qualities, which are crucial and important.
Special structural design effectively controlled its axial expansion
Our core shaft is produced with high quality material, so the following qualities can be guaranteed:
-- Withstanding of high torsion/torque, which is essential for polymer plasticizing process.
-- Having good fatigue resistance, which is a guarantee for long-term and high-load operation.
-- Having precision gear thread, this matched well with the internal gear thread of the screw shaft elements. This ensures the combination screw can meet the requirements of the require roundness and radial run-out of tolerance.
