If you need a hollow, thin wall bottle, tank or enclosure made from plastic, then you’ll need to have it blow molded. During the blow molding process, the plastic resin material is melted and then formed to create your desired hollow part. There are three blow molding processes we specialize in: extrusion blow molding, injection blow molding and stretch blow molded parts.
Blow Molding
Plastic Blow Molding – Extrusion, Injection & Stretch Blow Moulds – LDPE HDPE PET PVC PP
Types of Blow Molding at-a-glance:
- Extrusion Blow Mold (EBM) – A hot tube of plastic, called a parison, is dropped through an extruder into a water-cooled mold. Once the mold is closed, air is blown into the neck until the plastic forms into the desired blow molded part shape. This is the simplest blow moulding method.
- Injection Blow Mold (IBM) – Air is inflated into a hot and hollow parison (tube of plastic), into a mold and inflate it until the plastic conforms to the mold cavity design.
- Stretch Blow Mold (ISBM) – 2-step process where plastic is injection molded into a “perform.” Performs are made with bottle neck with threads on one end. Packaging is wrapped around the perform. Next, the perform is inserted into the blow mold. Air is inflated into the plastic until it it conforms to the mold cavity shape. While this process is more capital intensive and is recommended more for low production volumes and short runs.
