Extrusion Blow Molding
Extrusion blow molding is one of the simplest types of blow molding where a hollow tube (parison) is formed. To do this, material is forced between a die and mandrel. The parison is then enclosed by two halves of a mold cavity and the bottom is sealed. The neck of the bottle is formed with blow pins that are inserted into the top of the tube. The parison is then expanded with compressed air to force it against the cooled mold cavity walls. Once cooled off, the container is removed from the mold and trimmed of excess plastic or flash. That flash does not go to waste and is reprocessed.
Advantages of Extrusion Blow Molding:
- Mold tooling costs are lower
- Flexibility of tooling and production
- Interchangeable neck and body sections can be accommodated by the molds.
- Adjustable bottle weights.
- Neck inner diameters can be easily controlled to varying requirements.
- Can accommodate large range of container sizes (less than 1 oz. to more than 55 gallons).
- Wide selection of machine sizes.
- Varying sizes of bottles – long and flat or have handles.
