Bakelite parts are favored and loved by market consumers for their unique advantages. But do you know about bakelite parts? Today, let's follow us and find out how many processing methods are used to produce this product.
- Blisters: Vacuum forming is called blisters. It is a plastic processing technology. The main principle is to first heat the flat plastic cardboard to soften it, then absorb the vacuum to the mold surface and form after cooling. It is mainly divided into two categories: thick plastic sheet and thin plastic sheet. Widely used in automotive accessories, lighting, advertising, decoration, large mechanical enclosures, displays, air travel, electricity, bathroom and other industries.
- Injection: thermoplastic injection molding. The method is to melt the plastic and inject it into the film cavity. After the molten plastic enters the mold, it is molded into a specific shape by cold-pressing the mold cavity. Common products include computer case shells, connectors, phone cases, keyboards, mice, audio, and more.
- Blow molding: also known as hollow blow molding, is a rapidly developing plastic processing method. When heated (or heated to a softened state), a tubular plastic parison obtained by extrusion or injection molding of a thermoplastic resin is placed in a mold opening, and compressed air is introduced into the parison after the mold is closed, thereby making the plastic parison It was blow-molded and firmly adhered to the inner wall of the mold, and then each hollow product was obtained after cooling and demolding. The plastic processing technology for bottles, buckets, cans, boxes and containers used for packaging food, beverages, cosmetics and daily necessities is blow molding.
- Extrusion: Extrusion is also called extrusion in plastic processing, and also called extrusion in rubber processing. It refers to the processing method of heating and plasticizing the material through the interaction between the barrel and the screw of the extruder, which is pushed forward by the screw and continuously passed through the head to make various section products or semi-finished products. product.
