Plastic Injection molding, to those less familiar, may be defined as a manufacturing process for creation of products from plastic element. The plastic loses the heat and solidifies to the configuration of the mold cavity after it is forced into a mold cavity pushed into a heated barrel and mixed.

Six years hence, the first screw injection machine was constructed by American inventor James Watson Hendry, which provided greater control over the quality of articles produced and the speed of injection.

Ranging from buttons and combs to an array of technological products for several industries including toys, medical, automotive, consumer products, aerospace, etc., the industry has evolved and started manufacturing a huge range of plastic goods during the ensuing decades. Injection molding China is the most popular although there are various methods used in the manufacture of plastic goods.

Unlike metals, Plastic is lightweight and durable. Plastic is resistant to wearing, corrosion and tearing. Some striking advantages of this technique are no to finish parts after molding, repeatable high tolerances, high production capability, minimum scrap losses, and low labour costs. Of course, its own share of demerits is there in this technique - the process entails the need to design mouldable parts, potentially high operational costs, and high investment in equipment.

However, the rise of the plastic molding industry has occurred due to the steadily increasing demand for plastic products. Today, to those used in critical industry sectors like building construction and aviation, you would find the use of plastic from products of daily use - amongst others.

Most common method of plastic part manufacturing is the plastic injection molding. For mass producing of the same product, it is ideal. Today in almost all industrial sectors, we need machines and the demands for plastic products are growing at a rapid pace.

The latter is called as CNC plastic machine while the earlier versions are known just as plastic injection machines. In solving some of the problems associated, CNC plastic machine has succeeded with conventional molding processes.
