Twin-screw extrusion line

sheetfor PVCfor EVA

This production line is used to produce various sheets and coils with powder or powder as raw materials, with high efficiency, stable production and good yield. Applicable raw materials are PVC powder, EVA powder and various plastic modified materials. The sheet extrusion unit is a combination of extruder, three roll calendar, haul-off unit, winder (including waste sheet winder)and electric control cabinet. The main parts, such as screw, barrel, screen exchanger, T-die adopt superior alloy steel (38 CrMoAIA) with high hardness, strong corrosions resistance and long operating life after nitrogen treatment. The screw adopts big L/D (length/diameter) Ratio, equal plasticization and high plasticizing capability.Non-stop fast screen changer with double-sieve, controlled by hydraulic device, the operation is convenient and improve the production efficiency. The calendar, haul off unit and winder adopt integration design, fine appearance, convenient and fast installation and adjustment. The machine frame adopt square steel, to make sure the machine works stably in high speed. The motor is connected with gear box directly, improve production efficiency and lower energy consumption.
