In the production of foam boards, the mixed material enters the production line (counter-rotating twin screw extruder) to melt due to friction, shear, and heat. In the end, the extruder acts as a foam generator due to the heat generated. Chemicals are usually used as foaming agents that release carbon dioxide or nitrogen as they heat up. The released gas creates cavities in the PVC that are manageable by controlling the conditions and using processing aids. Then, these materials are passed through the sheet mold and, after exiting, the dimensions of the two plates are stabilized by a calibration system. At the final stage, the edges of the sheet are cut and sawn as required to prepare for packaging.

. PVC plastic artificial marble plate sheet board production line extrusion machine plant making machine electrical system has mainly applied imported parts, it has multiple alarm system, and there are few problems which can be easily eliminated. The cooling system has applied special design, heat emission area is enlarged, the cooling is rapid, and temperature control tolerance can be ± degree.

In the production of PVC foams, physical mixing is generally performed in the mixer in the first stages. In a more advanced method, turbo mixers are used to generate frictional heat with the high rotational speed of paddles. As the PVC powder heats up, the additives find the opportunity to penetrate into the particle surface. The heated powder is then cooled down and stored. This process is generally conceivable for most PVC products.
