Plastic finished product processingThere are many kinds of crafts, but in actual use, most manufacturers use only so many. Ruiqingxuan as the plastics industryHigh-quality mold injection manufacturerHere we lead you to learn more about several processing methods of plastic products that are common in our lives.

Extrusion: Extrusion is also called extrusion in plastic processing, and extrusion in rubber processing. It refers to a processing method in which materials pass through the action between the barrel and screw of the extruder, while being plasticized by heat, being pushed forward by the screw, and continuously passing through the head to make various cross-section products or semi-products. The extruded products are all continuous profiles, such as tubes, rods, wires, plates, films, wire and cable coatings, etc. The extrusion products produced by Baoyi use a variety of unused raw materials, among which the most commonly used are PC, ABS, PVC, and PS, PE, PP, TPE, TPE, TPU, etc. After the processing is completed, what appears in our lives are LED lampshades, drain pipes, supermarket price tags, and many other plastic products that are processed by extrusion.

Plastic: Thermoplastic injection molding. This method is to melt the plastic material and then inject it into the film cavity. Once the molten plastic enters the mold, it is shaped into a certain shape according to the mold cavity. Injection molded products are also very common in our lives. Our most common products mainly include: computer case shells, connectors, mobile phone shells, keyboards, mice, speakers, etc.

Blow molding: also known as hollow blow molding, a rapidly developing plastic processing method. The tubular plastic parison obtained by extrusion or injection molding of the thermoplastic resin is placed in a split mold while it is hot (or heated to a softened state). After the mold is closed, compressed air is injected into the parison to blow the plastic parison It expands and clings to the inner wall of the mold, and after cooling and demolding, various hollow products are obtained. The common plastic processing technology for bottles, barrels, cans, boxes and all containers for packaging food, beverages, cosmetics, medicines and daily necessities in our lives is blow molding.

Blister: Vacuum forming is called blister, which is a kind of plastic processing technology. The main principle is to heat a flat plastic hard sheet to soften it, then use vacuum to absorb it on the surface of the mold, and then cool it to form. It is mainly divided into two categories: thick blister sheet blister. It is widely used in industries such as automobile accessories, lighting, advertising, decoration, large-scale machinery housing, display type, travel and space type, major appliances, sanitary ware and other industries.
