The SJP serials parallel twin screw extrusion line is a kind of special equipment for

extruding of PVC powder.

1)With different sorts of molds and auxiliary machines,it can produce all sorts

of PVC plastic pipe material,bar material and granulation.

2)The screw has applied oil system,barrel is cooled by special wind cooling system.

3)The control system has applied computer control.

4)According to customer's requirements,more suitable screw can be made so as to

achieve best plasticity state and material quality.

5)The screw is made by high precision special digital screw miller,extruding property

can be highly harmonized.

6)It has firstly introduced technique of producing screw with variable pitch and depth,

so that the material can be more softly sheared and cut.

7)The distribution box is specialally designed,thrust bearing is fully imported,and the

drive life span can be prolonged.It can bear large extruding pressure.

8)The electrical system has mainly applied imported parts,It has multiple alarm system,

and there are few problems which can be easily eliminated.

9)The cooling system has applied special design,heat emission area is enlarged,the

cooling is rapid
