Forming and processing technology of detergent bottles

The molding process of detergent bottles refers to the process of making final plastic products from polymers manufactured by synthetic resin manufacturers. Processing methods (commonly referred to as one-time processing of plastics) include compression molding (molding), extrusion molding (extrusion molding), injection molding (injection molding), blow molding (hollow molding), calendering, etc. Blow molding Blow molding is also called hollow blow molding or hollow molding. Blow molding is a method of blowing a hot resin parison closed in a mold into a hollow article by the pressure of compressed air. Blow molding includes two methods: blow molding a film and blow molding a hollow article. Film products, various bottles, barrels, pot containers and children's toys can be produced by blow molding. Extrusion Extrusion molding, also known as extrusion molding, is a method of using an extruder (extruder) to continuously pass the heated resin through a mold to extrude products of the required shape. Extrusion is sometimes used in the molding of thermosetting plastics and can be used in the molding of foam plastics. The advantage of extrusion molding is that it can extrude products of various shapes, with high production efficiency, automatic and continuous production; the disadvantage is that thermosetting plastics cannot be widely processed by this method, and the product size is prone to deviation. compression molding Compression molding is also called compression molding or compression molding. Compression molding is mainly used for the molding of thermosetting plastics such as phenolic resin, urea-formaldehyde resin, unsaturated polyester resin, etc. Injection molding Injection molding is also called injection molding. Injection molding is a method of using an injection molding machine (or injection machine) to inject thermoplastic melt into a mold under high pressure and obtain products by cooling and curing. Injection molding can also be used for the molding of thermosetting plastics and foam plastics. The advantages of injection molding are fast production speed, high efficiency, automatic operation, and can form parts with complex shapes, which is especially suitable for mass production. The disadvantage is that the cost of equipment and molds is high, and it is difficult to clean the injection molding machine.
