Purging your blow molding machine is necessary to ensure optimal performance and a superior end product. While there are some differences between standard and custom blow molders, the blow molding design is similar enough that there is no real impact on the purging process. Even when it comes to extrusion blow molding vs. injection blow molding, purging is essential.
Of the many different machines used for manufacturing products, the blow molding machine is one of the most fascinating and useful. Known as extrusion blow molding, the simple explanation as to how this blow mold design works is that air is blown into a parison, shaping the hollow bottle as it inflates. However, there is much more to the plastic extrusion blow molding process.
