China Wholesale Twin Screw Rigid Pvc Sheet Extrusion Heat Profile Suppliers Factories - PVC windows and door profile production line – Qiangsheng Plastic

Features Specifications:

1. Model SJSZ series conical twin screw extruder is a kind of special equipment for extruding PVC compound. With different kinds of molds and auxiliary machines, it can produce all sorts of PVC plastic pipe, profile, plate material, sheet material, bar material and granulation.
2. The conical twin screws have applied oil cooling system. Barrel is cooled by special wind cooling system.
3. The conical twin screw extruder system has applied special computer control. According to customers requirements, most reasonable structure of conical twin screw can be made so as to achieve best plasticity performance and material quality.
4. The conical twin screw is made by high precision special digital screw miller; extruding property can be highly harmonized. It has firstly introduced advanced technique of producing screw with variable pitch and depth, so that the material can be more softly sheared and cut.
5. The distribution box is specially designed, pull force bearing is fully imported, and the drive life span can be prolonged. It can bear larger extruding pressure.
6. The electrical system has mainly applied imported parts, it has multiple alarm system, and there are few problems which can be easily eliminated. The cooling system has applied special design, heat emission area is enlarged, the cooling is rapid, and temperature control tolerance can be ± 1degree.
7.speed controlled by inverter, saving power and easy to adjust speed
8.extruder temperature controlled by Omron intelligent controller, temperature fluctuation self adjusting
9.low power consumption: lowest total production line consumption 25kw/hour
10. economical price, suitable for large scale investment.

Processing：

PVC powder+other addictive→mixing material by mixer→powder feeder→conical double-screw extruder→Die&mould→stainless steel vacuum calibration platform→ hauls-off machine→cutter→stacker.

Application:

The profile has the feature of low waster of energy, good performance, high speed and high efficiency, atc. The finished products produced by this machine has he feature of good surface, stronger compression resistance, light and heat stability, low size-changing and ageing resistance.
