During the following decades, the plastic injection molding industry has evolved and began producing a variety of plastic goods ranging from combs and buttons to an array of technological products for several industries including automotive, medical, and aerospace, consumer products, toys etc. Though there's several different methods used in the manufacture of plastic goods, plastic injection molding is the most popular.

Some striking advantages of plastic injection molding are high production capability; repeatable high tolerances, low labor costs, maximum scrap losses, and not very any need to CNC finished parts after molding.

Injection molding is the most general method of plastic part manufacturing. The demands for plastic products are growing at a fast pace and, today they need plastic injection machines in all industrial sectors.

Earlier, the plastic injection molding machines were by hand and automatically operated but now the machines can be operated in a computerized way. While the earlier versions are known as plastic injection machines, the latter is called as CNC plastic machine. CNC machining has succeeded in solving some of the issues associated with conventional plastic injection molding processes.
