Injection Blow Molds

The expert of MLT monitor injection blow molding carefully and follow the each step sincerely.

 

  • 1. In Injection Blow Molding method, a parison is produced by injecting a polymer into a hot injection mold around a blow tube or core rod.
  • 2. Then the blow tube together with the parison is removed from the injection mold and transferred to a blow mold.
  • 3. Air is injected under pressure blowing the polymer against the mold walls where it cools and freezes as with extrusion blow molding.

 

Injection Blow Molding is a more accurate and controllable process as compared to the Extrusion Blow Molding. It allows producing more complicated products from a wider range of polymer materials. However production rate of Injection Blow Molding method is lower than that of Extrusion Blow Molding.
