The Benefits of Blow Moulding

Posted on 11th February 2016

Blow moulding was developed in the 1930s, but it really took off in the late 1970s when the process was adopted by the soft drinks industry, when they started switching from glass bottles to plastic. By the end of the 20th century over 10 billion plastic bottles were being produced every year by the blow moulding method.


How Does Blow Moulding Work?


The process works by feeding a closed tube of molten plastic called a parison into a mould and then injecting air into the open end of the tube. The injected air causes the parison to expand and form the shape of the mould. Once the plastic has cooled, the mould can be removed and you have your hollow plastic product.


What Is Blow Moulding Used For?  


You can see how useful this process would be when it comes to the mass production of plastic bottles, ducts, flasks, tanks and containers of all kinds. Even some kinds of toys and sporting goods are suitable for this kind of manufacture.

What Are the Benefits of Blow Moulding?


Blow moulding is one of the most cost effective ways to produce your product. It is also a quick way to produce a high volume. If you need a lot of stock in a short amount of time and blow moulding was a suitable way to produce that stock, we would recommend it over injection moulding.
