Injection moulding is one of the most widely used manufacturing processes in the medical device industry due to its ability to produce high-precision, repeatable, and contamination-free plastic components. The process involves injecting molten medical-grade polymers into a precisely engineered mould cavity, where the material cools and solidifies into the required shape.<\/p>
