Blow plastic, also known as blow molding, is a manufacturing process that has revolutionized the production of hollow plastic parts. Its origins trace back to the 1930s, but it gained prominence in the mid-20th century with the advent of high-density polyethylene. Today, blow plastic is integral to countless industries, from packaging to automotive. The process involves melting plastic resin and forming it into a parison, which is then inflated inside a mold to create the desired shape. There are several variations, including extrusion blow molding, injection blow molding, and stretch blow molding, each suited to different applications. At Changzhou Pengheng Auto Parts Co., Ltd., we harness the versatility of blow plastic to produce non-standard products that meet complex requirements. Our expertise lies in addressing challenges related to specialized shapes, functions, and materials.
