In the plastic manufacturing industry, there are different ways to manufacture plastic parts. However, we have two popular methods of forming plastic parts. The two methods are injection molding and vacuum forming methods.
Are there things that are similar or different from these methods? Does one method have an advantage over the other? We will know these and more at the end of this article.
Let’s dive straight into the two plastic forming methods to know more about them.
Vacuum forming is a form of thermoforming that requires the placing of tinny plastic sheeting in an oven of industrial size. They are exposed to a high temperature to cause the material to soften and stretch.
There is pulling off the melted sheet against the mold by the air in the vacuum. The mold shapes the plastic. There is a cooling of the plastic to harden for release from the mold.
There are various advantages of the vacuum forming method. Some of them are:
Injection molding is a form that requires the feeding of plastic pellets in the hopper. The pellets are heated to melt into a liquid form. Under high pressure, the materials are injected into the mold on the double side where it cools and solidified.
When the cooling is complete, the two molds are opened simultaneously to release the parts.
Some of the advantages of Injection forming are:
Some of the similarities are:
Both are good for the production of plastic. However, we consider the part and specific requirements. Thus, the parts and requirements determine the best method to use.
