Different Blow Molded Solutions and Technology for Companies

There are several kinds of blow molding technology used to produce jars, jugs, and bottles. The typical options include reheat and blow molding, stretch blow molding, injection blow molding, and extrusion blow molding.

Blow Molded Solutions

Extrusion Blow Molding

Extrusion blow molding is the easiest solution. During the production process, a heated tubing material is lowered into an extruder. Then, a water-cooled mold surrounds the plastic material. When the mold closes, oxygen is shot inside of the neck and the top of the housing like a balloon. The mold freezes shortly after the plastic material expands. As a result, the material keeps its unique shape.

Injection Blow Molding

The heated plastic material is injected at the beginning of the production process during injection blow molding projects. The plastic slowly surrounds the blow stem after it is pulled into the cavity. This procedure establishes the weight of the material by creating the neck. At this point, the material travels to another station so that it can be transformed into a finished container. Injection blow molding is typically used when blow molding plastic companies manufacture small containers.

Stretch Blow Molding

Stretch blow molding helps manufacturers produce P.E.T. bottles, which are containers for juice and water. Most manufacturers produce the bottles with advanced machinery called ISBM. This equipment is only used during extremely large projects.

Reheat Blow Molding

Third-party vendors implement reheat and blow molding procedures. Many big businesses purchase the stock and place it inside of low-tech machines. The equipment blows the stock when the material reaches a certain temperature.

Out of all of these techniques, extrusion blow molding is the most cost-effective. Call Western Case at 877-593-2182 to start your project.
