The both layers are use shunt method, A & B layers proportion are according to your requirements.
The plastic material laminated together in the inside mold, it can ensure A&B layers are melting together well.
The die-head width is 1500 mm, use particular flow channel design, the die-head use by differential adjustment screw to modulate the die-head's size, adjust easy and fast, and it will makes the sheets become clear and even. the thickness is within 25mm.
This production line is capable of continuously producing mono-layer or multi-layer PP/PE plate and sheet with the width less than 3000mm and thickness of 0.25-25mm. The products are widely used in the fields of refrigerator, air conditioner, auto, advertisement, and construction, environmental protection, etc.
Extruder: Appropriate single-screw extruder(exhaust or not) should be chosen on the basis of different materials. Specially designed screw and advanced temperature controlling system ensure the good plasticization, high output and stable extruding.
Screen changer and mould: The quick screen changer of hydraulic system ensures the short course of screen changing without material-leakage. Reasonable structure of mould should be chosen in terms of material, whereas moulds of clothes-rack mode are widely accepted to regulate flow-distribution and guarantee even thickness of plates (sheets).
Three-roller calendaring machine: Inclined and vertical three-roller calendaring machine should be chosen according to the thickness of the plates(sheets). Temperature controller operates separately and gap among the three rollers can be adjusted freely, and the central roller has special design of regulating angle. Both ensure the excellent calendaring effect and even thickness of plates (sheets).
