Injection moulding is a process used for manufacturing parts. Parts can be made in many different shapes, sizes, and colors. They can be made from materials such as metals, electroless nickel, PTFE, nylon, polyurethane, fluoropolymers, rubber, polycarbonate, and different types of plastic.

Injection Moulding Qualities

There are many options to consider in injection moulding. Cost is a primary concern for many manufacturing companies. Cost can be saved in tooling, materials, size and weight of products, and design.

Plastics are commonly used for moulding because they are versatile and generally low in cost. However the tooling can be very expensive for the process. Companies save money on tooling by focusing on micro injections, or small parts made with smaller machines.

The first step in injection moulding is the melting of material. After the material becomes a liquid, it can be poured into a certain mold. The product can be ejected from the mold and used after it has cooled.
