The plastic processing industry is one of the world's fastest growing industries. The two major plastic processing methods are injection moulding and extrusion. Approximately 40percent of all plastics processed goes through injection molding machine. The advantages of injection molding machine are that the moulded parts can be produced economically in unlimited quantities with little or no finishing operations.

As a result of the perpetual changes in the standard of living and new products required by the market, the demands placed on the processors are arising with each passing day. This drives machinery manufacturer to develop innovative machinery upgrading their machinery. This new generation injection molding machine are expected to meet the processor's requirements because of consistency, accuracy, repeatability, energy efficiency and productivity, which will yield maximum returns.

Since 1872 when the first injection molding machine (Plunger type stuffing machines) was used, the machinery has come a long way. The changing needs reflect the dynamic growth of the industry. Apart from its own normal growth, the injection molding machine technology has been influenced by the advancement of other technologies like hydraulics, electronics, computers, robotics and the demands of modern, engineering-grade moulding materials
