1, extruder

The specially designed screw form and advanced control system ensure excellent high filling plasticizing ability and stable extrusion. And it has a dual machine co extrusion type, and the core layer can use high filling materials orrecyclePlastic is used as raw material for the surface layer to obtain low-cost and high-quality products.

2, network changer

Adopting a four mesh automatic screen changer, multiple mesh plates work alternately, with good sealing, wear resistance, and long service life. To achieve no material leakage, no oil leakage, no fluctuation, no shutdown, continuous operation without stopping, equipped with filter plate preheating and exhaust structure, material pressure, material flow, and material temperature balance are excessive during screen replacement, ensuring stable operation.

2, Mold

The mold is made of high-quality alloy steel（P20, 2211, 2216, 5CrNiMo, etc.) are equipped with built-in stainless steel heating rods for zone independent control, ensuring small errors in process temperature requirements. The internal gas diversion rod of the core rod evenly divides the gas chamber into multiple segmented areas, which can independently adjust the gas flow rate in each area, so that the gas flow can be evenly distributed in a very short time, with temperature output and stable products. The mold structure is optimized and designed based on the production experience of hundreds of sets of molds at home and abroad, ensuring uniform feeding pressure at the inlet and stable dischargeThe thickness of the board is uniform.

4, vacuumfinalize the designtower

The heat exchange and cooling systems of the vacuum shaping table are often effectively used interchangeably with the vacuum system to ensure shaping accuracy. The vacuum system consists of two independent subsystems, each equipped with multiple fixed three-point circulating vacuum pipelines. Equipped with a vacuum regulation system and a vacuum display system, it can achieve uniform and stable vacuum on the surface of the board.

5, traction machine

There are two tractors. The first one is high-power, high speed reduction ratio, multi roller type, low-speed operation, high traction, capable of uniformly and synchronously pulling up the plate from the shaping table. The second one is equipped with an oven to relieve stress and provide conveying services for the cutting machine. In addition, it is also equipped with a trimming device to ensure effective width and smooth trimming.

6, oven

The advanced large-area conductive heating method can effectively eliminate the stress on the board and further improve the flatness of the board. The oven box is made of stainless steel, which can effectively reflect temperature and improve energy efficiency.

7, corona machine

In order to improve the surface tension of the hollow sheet and thus enhance the fastness of the printing inkHollow grid board tablePerform corona treatment on the surface to create micro concave dense pores, roughen the plastic surface, and increase surface activity.

8Cutting machine

Combined with the Autonex counter and controlled by Siemens touch screen, it can accurately perform real-time fixed length cutting and automatic counting. By using alloy steel sharp blades for cutting, high-quality cutting can be achieved with a flat cutting end face.
