Posted by preform nicole on September 11th, 2018

Blow molding can be formed from a hollow plastic. It consists of a series of processes, including the production of hollow materials from thermoplastics. It has three main types, extrusion, injection and stretch blow molding. When the plastic with holes at both ends melts, the whole process begins. The hole is where air passes to form a blow mold.
Although blow molding Pet Bottle Preform molds have undergone a series of changes in history, some techniques have been developed to increase production.
