The shape of the plastic bottle affects the hot filling temperature

Plastic bottle molding refers to the process of making final plastic products from polymers made by synthetic resin manufacturers. Processing methods (called primary processing of plastics) include compression molding (compression molding) extrusion (extrusion molding) injection molding (injection molding) blow molding (blow molding) calendering, etc.

The operation can be automated, and injection molding is also known as 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, cooling and solidifying to obtain a product. Injection molding can also be used for the molding of thermosets and foams. The advantages of injection molding are fast production speed and high efficiency. It can form parts with complex shapes, especially suitable for mass production. The disadvantage is that the equipment and mold costs are high, and the injection molding machine is difficult to clean.

The maximum temperature of plastic beverage bottles can reach 121 degrees, but the shape of plastic bottles is different, and the high temperature is also different.

After years of work and research, the plastic bottle manufacturer summed up the experience and shared it with you: then peeled off from the roller of the calender, calendering is to pass the resin and various additives through the expected treatment (kneading, filtration, etc.) or multiple nip rolls turning in opposite directions are processed into films or sheets. A molding method that is then cooled and shaped. Calendering is a molding method mainly used for polyvinyl chloride resin, which can manufacture films, sheets, boards, artificial leather, floor tiles and other products.
