Blow Forming A Comprehensive Overview
Blow molding is a production technique used to create hollow plastic items, typically substantial ones like bottles, tanks, and car elements. The process involves expanding a preform – a small, heated plastic shape – with compressed air into a cavity. This expansion forces the plastic against the surfaces of the cavity, creating its desired shape. Once the plastic has solidified and stabilized, the component is removed and the die is released for the following cycle, making a generally fast and economical fabrication rate.
