Our Blow Molding Process

From product design and material selection to tooling and production, we help turn your container concept into a practical manufacturing solution. Our injection stretch blow molding process produces consistent, high-quality hollow parts in three controlled stages.

Preform Molding

Molten resin is injection molded into a preform, establishing the container's neck finish.

Stretch & Blow

The warm preform is stretched and expanded with air against the blow mold.

Cooling & Removal

The formed container cools, is removed from the mold and is checked against product requirements.
