What is meant by injection moulding?
Injection moulding is a manufacturing process that allows for parts to be produced in large volumes. It works by injecting molten materials into a mould (or ‘mold’ in the United States). It is typically used as a mass production process to manufacture thousands of identical items.
What is injection mold describe its components?
An injection mold is a tool comprised of a series of parts that allows molten plastic to be formed and cooled in such a way as to create a discrete part shape. Mold halves are attached to the molding platens by the clamp plates.
What are injection molds made of?
Injection molds, which are usually made from steel, contain cavities that will form the parts. Melted plastic is injected into the mold, filling the cavities. The mold is cooled, and the parts are ejected by pins. This process is similar to a jello mold which is filled then cooled to create the final product.
What are the advantages of injection moulding?
6 Major Advantages of Plastic Injection Molding
- High Efficiency- Fast Production. There are several good reasons that plastic injection molding is known as the most common and most efficient form of molding.
- Complex Part Design.
- Enhanced Strength.
- Flexibility- Material and Color.
- Reduced Waste.
- Low Labor Costs.
What is sprue bush?
The sprue bush is the connecting member between the machine nozzle and the mold face, and provides suitable aperture through which the material can travel on its way to the mould cavity or the start of the runner system in multi-impression molds.
What is ejector plate?
Also called a push plate. A plate that supports an edge of an ejector pin or a push back pin to eject a part from a mold. It is ejected by an ejector device of a molding machine, and returned to the original position when the edge of a push back pin collides with a cavity plate during mold clamping.
What is injection molding?
Definition of injection molding. : a method of forming articles (as of plastic) by heating the molding material until it can flow and injecting it into a mold.
What is in-injection moulding?

What is the meaning of “molding”?
: a method of forming articles (as of plastic) by heating the molding material until it can flow and injecting it into a mold.
What are the different injection moulding process variations?
There are many different injection moulding process variations, including: Injection moulding can be performed with a variety of different materials including metals, glass, elastomers, confections and, most commonly, thermoplastic and thermosetting polymers.
