How are the plastic products made of this texture processed?
Plastics processing technologyPlastic forming process. It is a general term for various processes that convert synthetic resins or plastics into plastic products. It is a larger manufacturing sector in the plastics industry. Plastic processing generally includes plastic batching, molding, machining, bonding, modification and assembly. The latter four processes are carried out after the plastic has been molded into products or semi-finished products. It is also called plastic two times processing.Mixed ingredientsPlastic processing of raw materials, in addition to the polymer, usually also added a variety of plastic additives (such as stabilizer, plasticizer, lubricant, coloring agent, reinforcing agent and filler etc.), to improve the performance of molding process and product or reduce the cost of products. The additive and the polymer are mixed and evenly dispersed into powder, also called dry mixed material. Sometimes, the powder is also processed into pellets. The powders and pellets are referred to as synthetic or moulded plastics.
jointThe method of joining a plastic part is welding and bonding. Welding is the use of hot welding electrode welding, hot welding using hot welding, and high-frequency welding, friction welding, induction welding, ultrasonic welding, etc.. Bonding method can be divided into flux, resin solution and hot melt adhesive according to the adhesive used.Surface modificationThe purpose is to beautify the surface of plastic products, usually including: mechanical modification, namely with filing, grinding and polishing process, the removal of parts on edges, burrs, and fixed size; finishing, including coating surface parts, the use of a solvent to surface brightening, covered with patterned thin film surface; colour. Including painting, printing and printing; metal plating, including vacuum coating, electroplating and chemical plating method etc.. Among them, the hot stamping is heated, under pressure, the hot film on the color of aluminum foil (or other pattern film) transferred to the workpiece. Many household appliances and building products, articles and so on use this method to obtain the metal luster or the wood grain and so on the pattern.assemblingThe operation of assembling plastic parts into complete products by means of bonding, welding and mechanical joining. For example: plastic profiles, through sawing, cutting, welding, drilling and other steps, assembled into plastic window frames and plastic doors.
FormingKey links in plastic processing. The various forms of plastic (powder, granular, solution or dispersion) made products or blank of desired shape. As many as 30 kinds of molding method. Its choice is mainly determined by the type of plastic (thermoplastic or thermosetting), the starting form, and the shape and size of the product. The commonly used methods for processing thermoplastics are extrusion, injection molding, calendering, blow molding and thermoforming. Thermosetting plastics are generally molded, delivered and molded by injection molding. Lamination, molding and thermoforming are the processes of forming plastics on a flat surface. The plastic processing method can be used for rubber processing. In addition, there are liquid monomers or polymers as raw materials such as casting. In these methods, extrusion and injection molding are the most widely used and the most basic molding methods.MachiningThe use of metal and wood processing methods, such as the manufacture of very accurate or small amount of plastic products, can also be used as molding auxiliary processes, such as extrusion section sawing. Because the thermal conductivity of plastic and metal and wood properties of different plastics, thermal expansion coefficient, low elastic modulus, when the fixture or tool pressure is too large, easy to cause deformation, cutting heat melting, and easy adhesion on the cutter. Therefore, the plastic processing, the tools used and the corresponding cutting speed, etc., should be adapted to plastic characteristics.The commonly used mechanical processing methods are sawing, cutting, punching, driving, planing, drilling, grinding, polishing, thread processing and so on. In addition, the plastic can also be used laser cutting, punching and welding.
