The Advantages and Disadvantages of Using Blow Molding for Plastic Products

Advantages of Using Blow Molding

The blow molding industrial vertical has evolved so that it is almost universally used with plastic. Plastic blow molding is advantageous due to the significant increase in production capabilities.

This allows companies to produce far greater quantities in a shorter period of time. Molding machines allow for three-dimensional moldings, significantly reduced flash, and a much faster production cycle.

The Disadvantages of Blow Molding

Blow molding does have its disadvantages as well. Polymer is a necessary material, which can have adverse affects on the environment. We have all seen the commercials describing the number of plastic water bottles that are used everyday around the world.

The biggest disadvantage may be the negative environmental effect associated with plastic use. Plastic isn’t biodegradable and it typically makes its way in massive quantities into landfills. There is also the concern caused by such a wide use of petroleum. This is a valuable resource that is being reduced by its use in plastic production. However, recycling is available to allow for plastic to be reused.

Techniques Used in Plastic Product Production

There are multiple techniques for plastic production. Perhaps one of the most common is extrusion. The extrusion form is that method mostly associated with glass blowers. Air is used to create the open inside part of the product.
