The process of Plastic Injection Moulding or PIM dates back to the 19th century. Although the methods, materials and machines have changed with time, the fundamental production principles remain the same. The products made from PIM are things that we use in our day-to-day lives. It is one of the most common methods used by injection moulding manufacturers to produce mass volumes of identical plastic products.
The process of injection moulding is not a complicated one. The entire process begins from thousands of tiny plastic pellets that are tossed into a giant rotating screw. As the pellets travel along, they are subjected to temperatures of around 400 degrees Fahrenheit. Due to the friction and force provided by the screw, the pellets slowly liquify and travel to a valve. This is where the molten plastic is forced under high pressure into a custom-made mould.
When the mould is completely filled, it goes into the next step called the holding phase. Clamps on the mould maintain the holding pressure until the plastic cools to a solid-state. This stage of the process is further aided by coolants that surround the mould. The cooled product is ejected from the mould and moves on to the finishing stages such as decoration, sub-assembly and packaging.
India plays an eminent role in plastic production and consumerism, with approximately 20 million metric tonnes of plastic being produced annually. Increased plastic usage has fueled the demand and growth of injection moulding products. Manufacturers state that there are more advantages that attribute to the popularity of PIM, which we have listed below:
High production output
Once the machine is installed and gets going, thousands of identical products can be made before the machine requires maintenance. A well-maintained mould tool tends to have a very long lifespan and thus boosts the output.
With injection moulding, the pros outweigh the cons. Apart from the few points listed below, there isn’t much to complain about plastic injection moulding.
