Lamination is primarily used to produce plastic sheets, copper-clad sheets, or products with simple shapes and large planar dimensions. These types of products cannot be processed using other molding methods, making lamination an independent technological process.
Lamination involves feeding multiple layers of adhesive-coated material or plastic sheets into a press, where they are heated and pressurized to form laminated plastic products. These products offer high quality and stable performance, but their drawback is intermittent production and low efficiency. The basic process includes stacking, feeding (commonly known as "entering the cylinder"), hot pressing, and unloading (also known as "exiting the cylinder"). Hot pressing is further divided into five stages: preheating, heat preservation, heating, temperature control, and cooling.
Although this process is relatively simple, quality control of the finished products is quite complex, thus requiring very strict operational procedures. Currently in my country, this process can only produce sheet products, and the dimensions are limited by the size of the press's hot plate; products larger than the hot plate cannot currently be produced.
