General description:
1. production line‘s features:
The structure is compact; superior performance, screw and barrel nitride alloy steel by optimization design, uniform plasticizing; high yield; long life and other characteristics. The screw adopts special mixing function and high plasticizing capacity. The design of coat hanger die adopts double flow design, the thickness of sheet can be adjusted precisely. The temperature control of 1C. Can accurately control the plasticizing process and sheet thickness and smoothness. Three roller machine adopts horizontal, vertical or inclined 45 degrees, can be freely adjusted. Sheet thickness control using screw adjustment and pressing wheel two-way adjustment control sheet thickness. Separate roller temperature control system to control the temperature of pressing roller plate thickness. Uniform. Slicing machine, sheet length and the number of precision. The winding device, with high torque motors, can adjust the speed and volume of tension. Automatic metering to set the length of product.
