Detailed

The process of extrusion blow molding generally includes the following 6 steps:

1. The extruder melts the plastic raw material, and shapes the melt sent to the die into a tubular parison.

2. After the parison is delivered to the set length, the clamping mechanism closes the blow mold and sandwiches the plastic parison between the two half-moulds.

3. Inject compressed air into the plastic parison through the blowing hole to inflate the parison to make it close to the mold cavity.

4. Wait for cooling and shaping.

5. The mold is opened, and the cooled product is taken out; (6) The product is decorated and the waste is recycled for reuse
