Injection Stretch Blow Molding (ISBM)

Injection Stretch Blow Molding (ISBM) involves molding the plastic into a ‘preform’ using the Injection Molding procedure. When these preforms are produced, they include the necks of the bottles as well as threads, known as the finish. These preforms are then cooled and put through the Blow Molding process. In the ISBM process, the preforms are heated above their glass transition temperature and then using blow molds, they are subjected to high-pressure air and blown into bottles. Typically, the preform is stretched with a core rod during the process.

We have world class Injection Stretch Blow Molding equipment with outputs of over 2000 bph. Creative Group has multiple single stage blow molding capabilites and is providing high quality bottles produced from multi cavity molds.
