Benefits of Blow Mold Manufacturing

This method of manufacturing offers many benefits when compared to other methods. It’s quick and efficient, and it can produce complex shapes with minimal cost. Blow molding also produces consistent parts with smooth surfaces that are often more durable than those created with other methods. It’s also capable of producing large amounts of products in a short amount of time. Furthermore, blow mold manufacturing is environmental friendly as most plastic materials used in the process are recyclable and reusable. All these factors make blow molding one of the most popular choices for mass production and a great option for businesses looking to save money while creating quality products.

Blow Mold Process

The plastic blow molding process is a popular manufacturing technique used to create hollow parts from melted plastic. It works by feeding plastic resin pellets into a heated barrel, then forcing the molten material through an extruder where it is pushed out of a die and into a closed mold. The part is then inflated, often with compressed air, until it takes its desired shape. Iceberg has advanced our technique over the last 2 decades. We've got state of the art blow molding machines that are well maintained and a team of experts onsite in Sturgis, Michigan ready to get to work for you. Watch the process in action.
