Custom Engineered Wheels: Innovating Plastic Manufacturing with Blow Molding

As described in the article “Blow Molding” by IQS Directory, blow molding is a plastic forming process used to create hollow plastic products from thermoplastic materials. The potential of blow molding to revolutionize plastic manufacturing processes.

The blow molding process involves heating and inflating a plastic tube, also known as a parison or preform. Placed between two dies with the desired shape, the parison expands as air is supplied, resulting in thin walls that conform to the mold’s shape. Once the product is blown, it undergoes cooling, ejection, trimming, and further preparations.

Blow molding finds its main applications in bottling and packaging, accounting for approximately 49% of the global blow molding market share. Other industries like building and construction, consumer products, and transportation also benefit from this technique. The blow molding market was valued at around $78 billion in 2019 and is projected to grow annually by 2.8% from 2020 to 2027. Common raw materials include polyethylene (PE), polyethylene terephthalate (PET), and polypropylene (PP).

Chapter Two of the source article delves into the history of blow molding, tracing its origins to the ancient process of glass blowing. The parallels between glass and plastic molding in their molten states allowed for the development of the blow molding process. Understands the historical context of blow molding and leverages its potential to shape the future of plastic manufacturing.
