The shape of the plastic cosmetic tube affects

Plastic cosmetic tube molding processing refers to the process of making final plastic products from polymers manufactured by synthetic resin manufacturers. Processing methods (called one-time plastic processing) include compression molding (compression molding) extrusion molding (extrusion molding) injection molding (injection molding) blow molding (hollow molding) calendering, etc. The operation can be automated, and 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 then cool and solidify to obtain a product. Injection molding can also be used for the molding of thermosetting plastics and foam plastics.

The advantages of injection molding are fast production speed and high efficiency. It can form parts with complex shapes and 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. The maximum temperature of the plastic beverage cosmetic tube can reach 121 degrees, but the shape of the plastic cosmetic tube is different, and the high temperature is also different.

After years of work and research, manufacturers of plastic cosmetic tubes sum up their experience and share with you: They are then peeled off from the calender roll. Calendering is the process of passing the resin and various additives through the calender after the expected treatment (kneading, filtering, etc.) The gap between two or more oppositely turned calender rolls is processed into a film or sheet.

A molding method that is cooled and shaped. Calendering is a molding method mainly used for polyvinyl chloride resin, which can produce films, sheets, plates, artificial leather, floor tiles and other products.
