PP PE PVC ABS PVDF board extrusion line

PP PE PVC ABS PVDF board extrusion line Process Flows

PP PE PVC ABS PVDF board extrusion line Extruder: GWELL as China Plastic Extruder manufacturer, choose single-screw extruder (vented or unvented) according to different materials. The screw adopts special mixing function and precise temperature control system to ensure high plasticization, high output and stable extrusion of plastic.

Temperature control ± 1 ℃ can accurately control the plasticizing process and plate thickness and flat shaping.

Screen change and mold: hydraulic quick screen change device ensures that there is no material leakage and the screen change is fast and effective; According to different materials, different structural forms are selected for the die. The clothes hanger die head adopts the double section flow design of page number, which is convenient for adjusting the uniform flow distribution, and the thickness adjustment of extruded plate is more accurate.

Three roller calender: 45 ° inclined three roller or vertical three roller or horizontal three roller calender is adopted according to the thickness of the plate. The three roller temperature control is independent of each other, the roller gap can be adjusted freely, and the special design of adjustable angle of the middle roller ensures the calendering effect and the thickness uniformity of the plate (sheet).

Plate thickness control adopts screw adjustment and two-way adjustment of pressing wheel, which can accurately control plate thickness. The independently controlled roller temperature control system can accurately control the temperature of the pressing roller barrel to make the thickness of the plate uniform.

Cooling roller support: equipped with corresponding cooling guide roller to make the cooling effect better. In addition, it is equipped with edge cutting device to ensure the fixed width and edge quality of the plate.

Transverse cutting machine: it is used for fixed length cutting, with cutting accuracy less than 2mm. Alloy blade or hard alloy saw blade is used, which is synchronized with the plate during cutting, so as to ensure the cutting quality of the plate and the long-term stability of cutting action.

PP PE PVC ABS PVDF board extrusion line Winder: it adopts high torque motor and friction winding, which can adjust the speed and winding tension at will, and can also provide other forms of winding according to the needs of users.
