Pipe Extrusion Purpose
Pipe Extrusion Purpose Product advantage:
Reasonable structural design, perfect plasticizing effect, high productivity.
Unique formula of double alloy spray welding on the surface of the screw can prolong the service life of the screw effectively.
Effectively avoid black and yellow lines while extruding pipe and profile materials.

Conical twin screw is
● suitable for all kinds of PVC power extruding. It can produce all kinds of PVC plastic pipe material, profiled material, board material, sheet material, bar material, granulation and PE wood plastic.

● The screw has applied oil cooling system. Barrel is cooled by wind cooling system. The screw is made by high precision special digital screw miller. Thus ensure each extruder device be exactly the same.

● The design of the screw has introduced advanced design concept and actual production status, adopt variable pitch, variable fit space, fine computational fluid dynamics and other design concepts. The materials can be more softly sheared, kneaded and compressed while transporting along the screw to meet the requirement of actual production.

1. Material: High quality alloy 38CrMoAlA is bought from from international well-known manufacturers.
2. Heat treatment: the raw material is treated by several heat treatment procedures such as quenching, tempering, qualitative,, nitride treatment, etc. to achieve the technical requirements of HB≥280, Nitride hardness (HV)≥980, Nitride thickness between 0.45mm and 0.65mm, Nitride frangibility≤Class I.
3. New material: To meet requirements from different customers, new materials, such as:SKD11, SKD61, etc., are sent to vacuum quenching treatment, then twice nitride treatments, thus to achieve higher abrasion performance.
4. Abrasive performance: Screw surface is spray welded by nickel-based alloy powder or carbides class alloy powder to improve screw abrasion performance and prolonging its service life.
