What material is primarily associated with injection moulding processes?

The material most commonly associated with injection moulding processes is plastic. Injection moulding is a manufacturing process specifically designed for shaping plastic materials into desired forms.

During this process, plastic pellets are heated until they melt and then injected into a mould under high pressure. This allows for the creation of complex shapes with high precision. Plastics, such as thermoplastics and thermosetting polymers, are extremely versatile and can be produced in a wide variety of forms and finishes, making them ideal for both large-scale production and intricate consumer products.

In contrast, glass, clay, and metal are typically processed using different methods. Glass is often shaped through techniques like blowing or casting; clay is usually formed through hand shaping, pressing, or extrusion; and metal is commonly formed through processes such as forging, casting, or machining. Each of these materials has its own properties and suitable manufacturing processes, but when discussing injection moulding specifically, plastic is the predominant material used.
