What is the Laminate molding?
Laminate molding is a molding processing method in which multiple thin-layer materials are molded by a process of pressurization, heat-hardening, and the like in a mold. According to the shape of the product and the type of resin. It can be a multi-stage pressing method, a normal pressure method, a heated roll pressing method, an autoclave autoclave method, a manual coating method, a vacuum forming method and the like. Depending on the pressure used, forks can be divided into high-pressure and low-pressure methods. In using this method, temperature and pressure conditions must be strictly controlled to prevent internal deformation and other defects.
The commonly used thin layer materials are paper pulp, glass fiber, carbon fiber, synthetic fiber, and paper, cloth, and non-woven fabrics as substrates, and then dip-coated with a resin. The lamination molding process is mainly used for the production of plastic sheets, double copper sheets or structurally simple products with large planar dimensions and large thickness. This type of product cannot be processed by other molding methods, which makes the laminate molding technology is an independent process technology.
|Laminate molding can be multi-layer adhesive material or plastic sheet into the press, by heating and pressing, pressed into laminated plastic products, this product is of good quality, stable performance, its shortcoming is intermittent production, Low production efficiency. The basic process is the process of stacking, feeding, hot pressing, and discharging. The hot press is divided into five stages: preheating, heat preservation, heating, constant temperature, and cooling. Although this process is relatively simple, the quality control of its products is a more complex problem, and therefore its technical operating procedures are very strict. Currently, in China, only plate products can be produced by this process, and the specifications are also limited by the size of the hot plate of the press. Products larger than the hot plate cannot be produced yet.|
