Plastic injection molding is simply the process of producing plastic items. It is done through a process that involves the injection of molten plastic into a metal mold of different shapes. This is done using high pressure since plastic has a very high viscosity. After that, it is cooled, and once solidified, a finished product is formed. The process utilizes various plastics, but the most used type of plastic is polyethylene either high or low density.


Plastic injection started in America after John W. Hyatt, an American inventor, made plastic billiard balls. This was something new since the balls were previously made out of ivory. Many investors saw this as an opportunity and soon, companies dealing with plastic injection molding emerged. Today, the industry has grown beyond borders and is known around the world. In this post, we will look at the plastic injection molding companies in Thailand.
