How is the common plastic product produced with automated production?

  Plastic products have been in our daily life everywhere, plastic bottles can be said that we are most familiar with one of the plastic products. How is the plastic bottles made that we see everyday?

  Blow molding is a process for the manufacture of plastics, by means of gas pressure to close the mold in the hot melt billet inflation to form hollow plastic products.

  The blow molding process includes several standard steps:
  The parison is mounted on the machine's nozzle and then placed in the mold, the mold is divided into two halves.
  • Hot air passes through the blank to expand into the shape of the mold.
  • Cool in the mold for a few seconds before cooling before stripping.
  • Clear the extra material at both ends and finish the finished product.

  Blowing is mainly used for the production of thin-walled hollow plastic products, such as water or soda bottles, pipes, car bumpers and so on. Most thermoplastics include materials such as PET, PS and PC that can be blown processed and glass. For the production of asymmetric parts, injection molding is usually used. During the blow molding process, the injection molding is in the parison and then moved to the blow molding machine injection blow molding process.

  For economic reasons, the need to produce hundreds to thousands of pieces per hour production, blow molding is generally mass production. With the increase in the level of automation equipment costs decline, a worker can control the operation of multiple automation equipment, low labor costs.
