Single screw extrusion is one of the core operations in polymer processing and is also a key component in many other processing operations. The foremost goal of a single screw extrusion process is to build pressure in a polymer melt so that it can be extruded through a die or injected into a mold. Most machines are plasticating: they bring in solids in pellet or powder form and melt them as well as building pressure.
Different types of extruders With different sorts of molds and auxiliary machines,
it can produce all sorts of PVC plastic pipe material, profiled material, plate material, sliced material, bar material and granulation.
It can also extrude PP.PE pipe at high speed by changing special barrel.
Computer control or conventional control is optional.
According to customer's requirements, most reasonable screw can be made so as to achieve best plasticity state and material quality.
The screw is made by high precision special digital screw miller; extruding property can be highly harmonized.
It has firstly introduced advanced technique of producing screws with variable pitch and depth, so that the material can be more softly sheared and cut.
The distribution box is specially designed, pull force bearing is fully imported, and the drive life span can be prolonged.
