PVC Foam Board Manufacturing Process

PVC Foam Board Manufacturing Process

WPC foam board extrusion line consists of automatic feeder, conical twin screw extruder, coat hanger type extrusion die, vacuum calibration mould, vacuum cooling table, embossing unit, multi roller traction machine, edge trimming unit, automatic saw cutter, stacker etc.

Detailed description

Product Description:

PVC foam board manufacturing process is generally consists of automatic feeder, conical twin screw extruder, coat hanger type extrusion die,multi roller traction machine,etc.The front side of the foam board was printed with a color, and a back coat was attached to the back of the film by a back coater. The back coating is made of special materials and is a high-energy affinity agent. It is because of this back coating that the PVC foam board can be tightly blended with the medium-density board or other sheets, and the glue is not opened for a long time. Since the entire production process is carried out at high temperatures, this makes the PVC foam board highly resistant to light and fire, ensuring high quality of the PVC foam board.

In addition, adopting the latest foam technology, and special design the screw and extrusion mould, PVC foam board manufacturing process ensures the high efficiency foam board, quickly calibration,the screw core temperature controlled by oil system, keep the temperature adjusting automatically, which ensures the moisture volatile enough, and makes the foam board harder than that of the traditional normal technology.

Features:

  • Stable work, high reliability, and strong traction ensure the smooth extrusion.

  • The effective L/D ratio allows for adequate residence time, excellent homogenization of natural fiber flour and polymer, and provides a large surface area for optimum heat transfer during foam board manufacturing

  • The extruder is equipped with a multi-ventilation system that removes moisture and volatiles and improves product quality.

  • The volumetric metering system also controls the mixing ratio of polymers, additives, profile grinding waste and pigments as an option for machines.

  • A wide range of products can be produced in different molds.
