Injection moulding is a widely used manufacturing process that is often used to produce plastic products which are used in automotive interior & exterior field,household applicance, medical devices and industrial field, like car lighting, coffee machines and detector for security. 

This process allows even shapes of high-complexity to be produced extremely quickly from both thermoplastic and thermosetting polymers, making it a highly efficient and cost-effective manufacturing option. In addition to plastics, injection moulding can be used with other materials.

How does plastic injection moulding work?

In simple terms, injection moulding  (plastic manufacturing) works by heating the polymer until it becomes liquefied, before injecting the molten plastic into a mould. This is then compressed and cooled to produce the final product.

The injection moulding process

Let's look in more detail at the injection moulding process and examine the different stages involved in producing the end product:

Stage 1: A moulding in the shape of the product is produced and split into two halves.

Stage 2: At the beginning of the manufacturing process, the two halves of the mould are clamped together tightly by the moulding machine.

Stage 3: Plastic pellets are loaded into the machine via a hopper, which then travel through a heater and are melted down into molten plastic.

Stage 4: The molten plastic is injected into the mould so that it completely fills it, before being cooled and turned into a solid form.

Stage 5: The two clamps are separated, with the finished product then being ejected from the moulding machine.

Injection moulding has become one of the most popular manufacturing processes used in the world today. It offers numerous benefits.
