Plastic Beverage Bottle Production Process?

- Aug 08, 2020-

The production process of beverage bottle can be divided into one-step and two-step methods: 1. One step: plastic particles are injected into the bottle embryo mold after heating and melting, and then cooled and shaped into semi-finished products (bottle embryo similar to tube shape, also known as tube embryo). When the bottle embryo is not completely cooled, it is heated and adjusted, and then sent to the blowing mold. After stretching and blowing the bottle, the plastic of the tube embryo is evenly distributed and close to each other Blowing mold: after the high-pressure blowing is completed, the cooling gas is injected. When the cooling is completed, the blowing mold is opened and the beverage bottle is formed. 2. Two steps: embryo injection and bottle blowing. Embryo injection: plastic particles are heated, melted and injected into the bottle embryo mold, and then cooled to form a semi-finished product (bottle embryo similar to tube shape, also known as tube embryo). Bottle blowing: the bottle embryo cooled to normal temperature is heated and adjusted, and then sent to the blowing mold. After stretching the bottle, the plastic of the tube embryo is evenly distributed and close to the blowing mold. After the high-pressure blowing is completed, the blowing mold is opened and the beverage bottle is formed.
