Plastic has photoelectric effect, thermoelectric effect, piezoelectric effect

The development direction of plastics can be summarized as two aspects. The first is to improve performance, that is, to modify existing varieties in various ways.

Its comprehensive performance is improved; the second is the development function, that is, the development of polymer materials with physical functions such as light, electricity, and magnetism, so that plastics can have photoelectric effects, thermoelectric effects, piezoelectric effects, and so on.

The joining of plastic products production Plastic processing methods to join plastic parts are welding and bonding. The welding method is hot air welding using electrodes, hot-melt welding using hot electrodes, and high frequency welding, friction welding, induction welding, ultrasonic welding, and the like. The bonding method can be divided into flux, resin solution and hot-melt adhesive bonding according to the adhesive used.

The purpose of surface modification for the production of plastic products is to beautify the surface of plastic products. Generally, they include: mechanical modification, that is, files, grinding, polishing, etc., to remove burrs, burrs, and correct dimensions on the part; finishing, including coating with paint Solvents are used to brighten the surface of the parts, and the surface of the product is covered with a patterned film; color painting, including painting, printing, and hot stamping; metal plating, including vacuum coating, electroplating, and chemical silver plating. Plastic processing hot stamping is to transfer the colored aluminum foil layer (or other pattern film layer) on the hot stamping film to the product under heat and pressure. Many household appliances and building products, daily necessities, etc., use this method to obtain patterns such as metallic luster or wood grain.

Assembly of plastic product production The process of assembling the finished plastic parts into a complete product by means of bonding, welding and mechanical connection. For example: plastic profiles are assembled into plastic window frames and doors through sawing, welding, drilling and other steps.
