ASA is a copolymer of styrene, acrylonitrile, and acrylic rubber. Technically speaking, ASA not only maintains the main characteristics of ABS, but also combines the advantages of acrylic weather resistance, making the product applicable for outdoor use. ASA film products contain a high content of ASA rubber powder raw materials, and the products have passed a 12000 hour weather resistance test. The color retention performance is many times higher than that of co extruded materials currently on the market. The uniformity of ASA film is higher than that of co extruded material, with no thin spots or color differences, and no waste of edge materials. Therefore, the ASA cast film production line has become a development trend at present.

The characteristics of the ASA cast film production line equipment produced by our company are:

1. The entire equipment adopts PLC, closed control, one click acceleration, and easy operation.

2. The special screw design of the extruder ensures plastic melting, uniform color, and high extrusion volume

3. The fully automatic mold, combined with a thickness gauge, can effectively fine tune the thickness deviation of the melt on the transverse width of the mold head, ensuring a thickness uniformity of ± 1 thread.

4. The casting roller adopts an internal channel integral machining method to ensure temperature control of plus or minus 1 degree and rolling surface control accuracy of plus or minus 1 thread, ensuring more accurate thickness of the casting film.

5. Using tension sensors and control systems to ensure tension control is positive or negative by 1 Newton.

6. A complete set of servo motors, combined with servo controllers, make the equipment operate more accurately.

7. The fully automatic cutting and rewinding machine has two functions: contact rewinding and gap rewinding. The rewinding has taper tension control and an adjustment range of 5-200N/M
