15 Facts About Injection moulding

Injection moulding is a manufacturing process for producing parts by injecting molten material into a mould, or mold.

Injection moulding can be performed with a host of materials mainly including metals, glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers.

Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars.

Injection moulding uses a special-purpose machine that has three parts: the injection unit, the mould and the clamp.

The versatility of injection moulding is facilitated by this breadth of design considerations and possibilities.

Injection moulding is used to create many things such as wire spools, packaging, bottle caps, automotive parts and components, toys, pocket combs, some musical instruments, one-piece chairs and small tables, storage containers, mechanical parts, and most other plastic products available today.

Injection moulding is the most common modern method of manufacturing plastic parts; it is ideal for producing high volumes of the same object.

Injection moulding uses a ram or screw-type plunger to force molten plastic or rubber material into a mould cavity; this solidifies into a shape that has conformed to the contour of the mould.

Plastic injection moulding industry has evolved over the years from producing combs and buttons to producing a vast array of products for many industries including automotive, medical, aerospace, consumer products, toys, plumbing, packaging, and construction.

Since 1995, the total number of available materials for injection moulding has increased at a rate of 750 per year; there were approximately 18,000 materials available when that trend began.

Injection moulding machines consist of a material hopper, an injection ram or screw-type plunger, and a heating unit.

Rubber injection moulding process produces a high yield of durable products, making it the most efficient and cost-effective method of moulding.

Traditionally, the injection portion of the moulding process was done at one constant pressure to fill and pack the cavity.

Injection moulding is a complex technology with possible production problems.

Power required for this process of injection moulding depends on many things and varies between materials used.
