Injection moulding stands as a cornerstone in modern plastic manufacturing, revolutionizing the production of various components across industries. Furthermore, It can rapidly produce identical parts by melting plastic granulates and then injecting them into a mould. Injection moulding can produce complex parts at a low price. Despite the low price, Injecting moluding machinery produces a high percentage of the products we use daily.
Since injection moulding enables a a cheap and efficient production of plastic goods that find applications across nearly all industries. This includes food packaging, electronics, household goods, automotive parts, medical products and many more. They facilitate the cheap and efficient production of plastic goods used in almost all industries.
How does Injection Moulding Work?
- Mould Design: You must create a metal mold in the shape of the desired plastic product. Usually, the mould is made of steel of aluminum. It has two halves which come together to form the finish product. The mould is hollow on the inside to allow melted plastic to flow into it. Moulds are specific to each product and needs to be created for each new product.
- Selecting and Preparing Plastic: This process begins with selecting the suitable plastic material which is in the form of plastic pellets. The pellets are fed into a hopper. The material enters an extrusion screw where it is compressed and heated to its melting points. Because different types of plastics have different melting points. Reaching the correct temperature range for a plastic’s melt point is important for a successful result.
- Injecting the Plastic into the Mould: Inject the molten plastic into the mold cavity under high pressure. While under this immense pressure, the mould holds the desired shape and design of the final product. The injection process fills the mould with molten plastic, shaping it precisely to the mould’s configuration.
- Cooling and Finishing: Lastly, Once the plastic has filled the mould, it undergoes cooling to solidify. Next it takes the shape of the mould. Though cooling times vary based on the material and product complexity. After solidification, the mold opens, and the finished product is ejected. Finally, it is then ready for further finishing processes if needed, such as trimming or assembly.

Plastic Types for Injection Moulding
Before the production can begin, selecting the appropriate plastic material is crucial for the injection moulding process.
These are some common types used:
Polyethylene (PE): Versatile and flexible, used in bottles, toys.
Polypropylene (PP): Heat-resistant, ideal for packaging, automotive parts, and medical devices.
Acrylonitrile Butadiene Styrene (ABS): Known for impact resistance, used in keyboards, LEGO bricks, and automotive trim.
Polycarbonate (PC): Transparent and strong, used in eyewear and medical devices.
Polyethylene Terephthalate (PET): Transparent and recyclable, found in beverage bottles and food packaging.
Nylon (PA): Durable and heat-resistant, suitable for mechanical parts and gears.
