Generally there are two steps to injection stretch blow molding. The first step is to injection mold preforms and the second step is to blow mold containers from the preforms. These two steps can be done in one machine in 1-step molding, or two different machines are required for 2-step molding. 1.5-step molding is a unique concept in between these two. ASB supports all three molding processes.
Finished containers are produced directly from plastic resin in one machine. The 1-step 4-station molding process is the core of ASB.
Finished containers are produced directly from plastic resin in one machine. Preform molding and blow molding are divided for efficiency.
2-Step Double Blow
This process enhances heat-resistance of PET containers increasing usability. 2-step double blow heat-set technology from ASB.
ASB's expertise to fullfill customers' various needs. ASB has developed many specialized techniques enabling enormous flexibility of production.
