 Surface modification of plastic products aim is to beautify the plastic surface, typically include: mechanical modifications, namely with filing, grinding, polishing and other processes, the removal of the parts burrs, size, etc. and amendments; finishes, including paint coating system surface, surface brightening with a solvent, with a pattern of thin-film paste with surface coating products; Shi Cai, including painting, printing and stamping; metallization, including vacuum coating, plating, silver plating and chemical method. Stamping plastic processing is heated, under pressure, the hot stamping film, an aluminum foil layer color (or other pattern layer) was transferred to the article. Many household appliances and building products, daily necessities, etc., this method to obtain metallic or wood grain and other patterns. Machining plastic products have borrowed metal and wood processing methods, such as plastic octagonal self seal bags, manufacture very precise size or a small number of plastic self-sealing bags of dumplings octagon, but also as an auxiliary molding processes, such as extrusion Cutting profiles. Since the performance of plastics with different metals and wood, plastics of poor thermal conductivity, thermal expansion coefficient, low elastic modulus, when the pressing jig or tool too, tends to cause deformation, cutting heat easily melted, and easily adhered to the tool on. Therefore coffee octagonal self seal bags, plastic machining, the use of knives and cutting speed would have to adapt to the corresponding plastic characteristics. Conventional machining methods are sawing, shearing, punching, car, plane, drilling, grinding, polishing, thread processing. In addition, the plastic can also be laser cut off, drilling and welding.
