ASB’s three unique molding processes for injection stretch blow molded plastic containers.
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 process.
