Injection moulding is an industrial manufacturing method for creating objects by inserting heated material into a mould by means of an injection needle. Injection molding can be done with a host of different materials mainly consisting of plastics, thermoplastics, thermoform plastics, and more recently thermoplastic and epoxy polymers. The moudings or shells that result from the processes in injection moulding are generally referred to as parts. The process itself is very simple and straightforward. The injection of the material to be molded into the mould is carried out either by manual effort or by an automated system.

There are many different types of injection moulds used today. The most popular are known as cavity injection moulds or cavity casting moudings. A cavity injection mould usually consists of a plastic or rubber mold in a closed chamber that is insulated from the outside world by a thin sheet of plastic. As the plastic melts in the mould, it is forced through a small hole at the top of the cavity so that it fills the entire plastic shell. This is then cooled (usually by water or a cooling agent) before it is inserted into the appropriate cavities within the object to be manufactured.

Plastic injection moulding is most commonly utilised in the manufacture of plastic toys. These come in all shapes, sizes and forms. The first plastic injection moulds were used in Japan in the 1950's, but they were rather primitive by today's standards. Advances in technology have led to significant developments in injection moulding equipment and techniques. Most major manufacturers utilise a process called vacuum deposition or vacuum baking to produce their products. The concept is similar but with a much higher vacuum and lower temperatures.

The advantages of using plastic injection moulding technology are many. One of the primary benefits is that it produces products that are highly resistant to any damage. This is achieved by the use of high quality plastics and alloys that can withstand a great deal of wear. The other major benefit is that plastic materials do not require a large amount of heat to set up and this reduces manufacturing costs drastically. Heat setting up can take a lot of time but once done, the plastic materials are usually very hardwearing.

There are a number of advantages associated with the use of injection moulding. One such advantage is the use of plastics and alloys with low temperature resistance properties. Low temperature resistance properties means that the plastics and alloys can be brought into being quickly during production. In a way this also means that the tools used for injection moulding are also of low cost. It is possible to create a wide range of products if a company uses high quality and low volume plastics and alloys with very low temperature resistance properties.

The other main advantage of the injection moulding process is that it provides greater speed with respect to other manufacturing methods. In other words, the moving half support plate is able to provide the customers with a greater degree of flexibility. This is because the moving half support plate can be adjusted in order to alter the level of support for a particular product.
