The process begins by heating thermoplastic materials until they melt, allowing them to flow easily. This molten plastic is then injected under high pressure into a precisely designed mould, which shapes the material into the desired form.

Once the plastic cools and solidifies, the mould opens, and the finished part is ejected. Thermoplastics are favoured for their ability to be reheated and reshaped, making them recyclable and versatile. The process enables high production rates, intricate designs, and tight tolerances, making it ideal for various applications, from consumer goods to automotive components.

Key advantages include reduced waste, lower energy consumption compared to other methods, and consistent part quality. Injection moulding of thermoplastics is a cornerstone of modern manufacturing, contributing to efficiency and innovation across multiple industries.
