A Quick Guide to Know About Blow Molding


Blow Molding Machine

The interesting thing about blow molding is that it creates products for everyday use without people even knowing about it. As a prime example, the plastic water bottle that individuals carry around results from a manufacturing process that involves a plastic molding machine.

In the U.S. manufacturing industry, blow molding ranks number three. That means it’s a critical technique for producing all sorts of plastic products. Not only does an injection blow molding machine make life easier for millions of people, but it also saves them money.

What Does a Plastic Molding Machine Do?

With this type of machinery, manufacturing companies can produce a broad range of plastic products. The process involves heating a tube of plastic. This preform or parison reaches a melting point. From there, the melted plastic goes into a mold.

The injection blow molding machine next forces compressed air into the mold, which in turn inflates the molten plastic. You could think of this much like blowing up a balloon. However, the product comes out in the shape of the mold yet hollow on the inside. The two things that determine the thickness of the product include the amount of plastic used and the level of air pressure.

The blow molding process goes back to the 1800s, although, at that time, craftsmen used glass instead of plastic. Over the years, this process has advanced tremendously. That’s why today’s top injection blow molding machine manufacturers can provide their customers with state-of-the-art machinery.

Examples of What a Plastic Molding Machine Produces

For a better understanding of how valuable this machine is to manufacturers, consider some of the end-products it makes:

  • Coolers
  • Construction barrels
  • Fan housings
  • Stadium seats
  • Toys
  • Sporting goods
  • Watering cans

Due to its versatility, multiple manufacturing industries rely on an injection blow molding machine. For instance, it’s critical to the automotive industry. As a safe, reliable, and fast process, these automakers use this process for all kinds of parts and components. That includes fenders, paneling, consoles, ductwork, mudguards, seating, and many more.

Types of Plastic Materials Used

Another advantage of the injection blow molding machine is that manufacturers can use many different types of plastics. Just a few of these options are PVC, PET, nylon, polypropylene, and both low- and high-density polyethylene.

Advantages of Blow Molding

As shown, this process is highly advantageous. It’s safe, reliable, and cost-effective. Manufacturers can also use an injection blow molding machine to produce a single product or for mass production. It’s also ideal for anything that doesn’t require connecting of halves or assembly.
