Plastic Injection Molding is a production process for creating large parts by injection molding molten plastic material into a pre-manufactured mold, or mold. Injection molding is done with a variety of materials most frequently including metals, thermoplastics, glass, thermoplastic, and thermoplastics/elastomeric confectionals. Plastic Injection Molding (PIM) is used in a wide range of manufacturing industries including automobiles, military aircraft, toys, furniture, packaging, and even medical devices. Plastic Injection Molding offers a fast production rate and unlimited customization to fit almost every business need.

The process begins with two halves of an empty plastic bottle or container that have been drilled with holes to accept the bulb syringe tip and threaded rods. One half of the container is filled with polyethylene tubing that is attached to a small air pump. The other half of the bottle is filled with plastic material such as polyurethane foam, polystyrene beads, and clear polycarbonate sheets. The second half of the plastic container holds the mold material to be formed into the plastic parts being manufactured. The plastic material and plastic injection molding machine are placed inside the first plastic shell.

The process used in manufacturing parts is similar to those used in assembling assembly line machinery. A process called as Plastic Injection Molding or PMM is followed where the plastic components are placed into the moulds. The plastic material and plastic injection molding machine are priming together using mechanical force. Once the plastic components are in place, they are slowly cooled using liquid nitrogen. Finally the plastic parts are ejected out of the moulds, after which the cooling process is completed.

As discussed above, the process used in manufacturing plastic products is very similar to that used in assembly line production. However, there are several differences in the manufacturing of plastic parts. In the case of injection molding, the plastic components are shot or pressed together in one piece. Once the components are pressed together, they are melted using high temperature by means of a furnace. The hot plastic melts the metal components that are required for making the plastic part.

In the case of producing parts made from plastic instead of metal, the process used is different. In the case of plastic injection molding machine, one or two cylindrical pieces are shot into the cavity with the help of a robotic arm or a rotating drum. A single cylindrical mold is then inserted into the open cavity for forming the plastic part. Once the mold is inserted, it is covered with sheet metal that has been melted on its edges by the closing of an injection mold machine.

In short, the process used in manufacturing plastic products is similar to that of pressing or casting but it is done using a different set of tools. However, the most significant difference between the two processes is that, CNC machinery allows the manufacturers to control the sizes and the shapes of the custom plastic parts. This way, they can ensure that the products come in perfect, standardized sizes so that it can be utilized for a number of applications including automotive, hobby products, toys, etc.
