Introduction to Plastic Sheet Extrusion Production Line

The PMMA acrylic sheet production line can continuously produce single-layer and multi-layer sheet products of PP, PE, ABS, PMMA, PC, PS, PVC. The width of the board is below 3000mm, and the thickness is 0.15-50mm.

Composition of plastic sheet extrusion production line

Extruder:

According to the different materials, a single screw extruder (with or without exhaust) is selected. The screw adopts special mixing function and precise temperature control system to ensure high plasticization and stable extrusion of plastics with high output.

Temperature control of ± 1 ℃ can accurately control the plasticizing process and the thickness and flatness of the board.

Mesh changing and mold: Hydraulic quick mesh changing device ensures no material leakage during mesh changing, and mesh changing is fast and effective; According to different materials, different structural forms are selected for the mold. The hanger type mold head adopts a page double flow design, which facilitates the adjustment of uniform flow distribution and more accurate adjustment of extruded sheet thickness.

Three roll calendering machine: Depending on the thickness of the board, a 45 ° oblique three roll, vertical three roll, or horizontal three roll calendering machine is used. The temperature control of the three rolls is independent of each other, and the gap between the rolls can be adjusted freely. The special design of the adjustable angle of the middle roll ensures the calendering effect and the uniformity of the thickness of the board (sheet) material.

The thickness control of the sheet metal can be accurately controlled by adjusting the screw and the pressure wheel in both directions. The independently controlled roller temperature control system can accurately control the temperature of the pressure roller drum to ensure uniform thickness of the sheet metal.

Cooling roller bracket:

Configure corresponding cooling guide rollers to achieve better cooling effect. It is also equipped with a trimming device to ensure the quality of the board's fixed width and edges.

Horizontal cutting machine:

Used for fixed length cutting, with a cutting accuracy of less than 2mm, using alloy blades or hard alloy saw blades. The cutting is synchronized with the sheet metal to ensure the quality of the cut surface and long-term stability of the cutting action.

Winder:Using a high torque motor and friction winding, the speed and winding tension can be adjusted freely, and other forms of winding can also be provided according to user needs.

PMMA sheet (acrylic sheet/GPPS sheet)

Purpose:Widely used in instruments, instrument parts, lighting fixtures, decoration, building materials, aircraft, automotive parts, medical equipment, craft products, electrical insulation materials, specimens, signs, as well as various light industry, cultural and educational, daily necessities, etc.
