Plastic injection molding process
Plastic injection molding is the process of melting plastic granules until they are very soft then injecting the melted plastic, under high pressure, into a mold. This results in the plastic taking the exact shape of the mold. After sufficient cooling, the mold is opened releasing the solidified and hardened plastic part. The process is then repeated over and over again until the order quantity is complete.
This process is suitable for the production of a large number of parts. It is a very rapid manufacturing process. The steps followed in plastic molding include;
This is the tightening of the mold to ensure that the plastic melt does not escape when pumped into the mold under pressure.
The melted plastic is pushed from the barrel under pressure into the mold.
This is the application of pressure into the mold to ensure that all the cavities inside it are filled.
The formed plastic part is allowed to cool on its own inside the mold.
Opening of mold
The movable platen is moved away from the fixed platen to open the mold and release the molded product.
The molded product is removed from the mold with the use of air blast, a rod or a plate. J-CAD has state-of-the-art machines and highly skilled mold operators with years of experience to ensure that your products are of very high quality and are outstandingly accurate.
Our presses range from 3 to 30 ton. Our equipment is custom designed for micro-molding. This ensures maximization of parts per second hence minimizing losses and greatly controlling shot size. All of our machines are also highly mechanized to ensure that in-line inspections, insertion and removals of over molding and part removal are very cost- effective. That explains why our services are very affordable.
