Moulding is the process of shaping liquid or soft raw materials by using a fixed frame called a mould or a matrix. The mould is made of a metal container where liquid, plastic, metal, ceramic, or glass is poured. The goal is to create multiple uniform copies of the product as the final product. The liquid cools down and takes the shape of the mould or the container. The product is removed by using release agents or ejection pins. A product can be moulded in different ways. The different types of moulding methods of: Injection Moulding Injection moulding is a manufacturing process in which molten material is injected into a mould. A lot of materials can be used for injecting. For example, metals, glass, elastomers, confections, thermoplastic and thermosetting polymers. The material is placed in a heated barrel, mixed using a helical screw, and injected into a mould cavity. This material is cooled and hardened to the shape of the cavity.
