How ordinary items are made using plastic injection molding

Increasing use of thermoplastics in manufacturing took place during the middle of the past century, coming on especially strong during the war years, 1940-45, where many applications substituted the use of plastics for metal. Even in the sixties it was a booming and yet still infant, emerging technology. The 1967 movie, “The Graduate,” starring Dustin […]

Blow vs Compression vs Extrusion vs Injection Molding Machine

Blow molding – well suited for hollow objects, like bottles The process follows the basic steps found in glass blowing. A parison (heated plastic mass, generally a tube) is inflated by air. The air pushes the plastic against the mold to form the desired shape. Once cooled, the plastic is ejected. The blow molding process […]
