Layout:

PVC Raw material+additive→Mixing Unit→Auto Feeder→Conical Twin-screw Extruder→-Moulds→Vacuum Calibration Tank→Haul-off&Cutting Machine→Stacker

Features specifications:

1.PVC Profile Extrusion Line is mainly used for the PVC corners, small boards and conduits extrusion. also can be used to produce ABS,PP,PS,PC profiles making after changing the extruder.

2.PVC Profile Extrusion Line Screw adopts oil cooling system. Barrel uses a special air cooling system .Plastics mixing uniformity, high output, wide application range, high reliability. Gear box, distribution box specially designed reinforced thrust bearings, drive torque and long service life.

3.The major part mainly adopts imported components and has a number of fault alarm function, simple operation, easy maintenance,etc.

4.The profile cutting also adopt the PLC control system, ensured the length tolerance in control.

Main technical parameter:

Use and maintenance:

Plastic profile extrusion die is the core part of extrusion production. The technical state of plastic profile extrusion die is directly related to the stability of extrusion production, the quality of extrusion products, the efficiency of extrusion production and the service life of the die itself. Therefore, the correct use and maintenance of plastic profile extrusion dies is very important.
1. Unpacking inspection of plastic profile extrusion die after arrival
Unpacking inspection, the packaging is intact: After unpacking, take out the packing list, the instruction manual and other technical documents, and build the parts, accessories and special tools according to the contents of the packing list.
2. Half technical requirements and status of plastic profile extrusion dies
>> Plastic profile extrusion die, especially when the extruded material is modified polyvinyl chloride, the molded parts are generally made of corrosion-resistant materials such as stainless steel, and tempered to HRC24 or above to ensure a certain service life.
>> The working surface of the die, the shaping die and its parts should be smooth, and there should be no defects such as bumps, scratches, burrs, attachments and rust.
>> The die runner system should be gentle along the direction of the melt flow, avoiding sudden changes in the cross section and the stagnant zone.
>> There should be reliable positioning between the templates. The repetitive error of the corresponding position between the templates is not more than 0.03mm. The joint surfaces of the plastic extrusion die and the splicing splicing should be in close contact with each other. Must not be greater than 0.02mm.
>> The cooling system and vacuum system of the fixed mold should be smooth and not leaking. Under normal circumstances, the water and gas systems should not collude with each other. The water pipe joint of the plastic profile extrusion die sizing die, the vacuum pipe joint shall have obvious signs and shall not affect the connection of the pipeline.
>> Plastic profile extrusion die setting die should be flexible and flexible, and the sections in the fixed die and water tank should ensure a certain degree of coaxiality.
