Plastic Injection Molding

Plastic Injection molding(moulding) is a method of producing shapes for industrial products. The injection molding process refers to a process of producing a semi-finished part of a certain shape by pressing, injecting, cooling, and detaching the molten raw material.

The injection molding process of plastic parts mainly includes five stages, including mold clamping - filling - holding pressure - cooling - demolding.

The sequence of events during the injection mould of a plastic part is called the injection moulding cycle. The cycle begins when the mould closes, followed by the injection of the polymer into the mould cavity. Once the cavity is filled, a holding pressure is maintained to compensate for material shrinkage. In the next step, the screw turns, feeding the next shot to the front screw. This causes the screw to retract as the next shot is prepared. Once the part is sufficiently cool, the mould opens and the part is ejected


Advantages

The injection molding method are fast production speed, high efficiency, automatic operation, variety of colors, shapes from simple to complex, the size can be from large to small, and the size of the product is accurate, the product is easy to be replaced, and the shape of plastic parts can be complicated. Plastic injection molding is suitable for molding machining such as mass production and complex shapes.


Application

Injection molding is widely used in the following industries:

●  Electronics

●  Electrical appliances,

●  Auto parts

●  Kitchen supplies

●  Medical supplies

●  Cosmetics

●  Sporting goods

●  And more…

Examples of parts made by molding include: Gears, Enclosures, Brackets, Robot Parts, Washers, Front Panels, Motorcycle Parts, Auto Parts, Toy Parts, Knobs, Pulleys, packaging, appliance parts, power tool components, electronic enclosures and valves.
