Injection moulding refers to a production method for making parts by inserting molten plastic into a mould, which then seals it. Injection moulding is generally done with a variety of different materials such as thermoplastics, glasses, plastics, and most often rubber. The material that is injected into the mould is then heated and cooled until it reaches the necessary thickness, such as when rubber is being poured into moulds. This is used to form part pieces out of a solid material, as well as for the creation of different shapes. Once the object is formed, the mould is closed, and the item is ready for shipping.

Injection moulding has been around for a very long time. There are some people who believe that the first injection moulds were made in ancient China. Another theory is that the first one was developed in France during the early 1800s. The process that was used to make these first injection moulds was using copper pots and pans. However, the first known use of the process was in the manufacturing of guns. Today, the process is used to produce all sorts of items including plastic parts, rubber parts, metal parts, ceramics, glass parts, etc.
When using an injection mould to make an item, a number of methods must be used to ensure that the injection mould doesn’t leak. The first of these methods involves creating a seal between the material being moulded and the outside environment, called the injector wall. This is typically made from a variety of different materials but is typically made up of plastic. The other methods that are used when making these products involve making the plastic component a very solid substance that will not break when heated.
