What is injection Moulding step by step?

Injection moulding involves a high pressure injection of a polymer into a mould where it is shaped. The whole injection moulding process usual lasts from 2 seconds to 2 minutes. There are four stages in the cycle. These stages are the clamping, injection, cooling and ejection stages.

How does the clamping unit of an injection Moulding machine move?

The Clamping unit One platen is fixed to the machine bed (the fixed platen). One half of the mould tool (the fixed half) is bolted or clamped onto this platen. This is used to couple to and move devices within the mould tool that force the moulding off the tool once cooled and the mould is open.

What is the process of injection molding?

What is Injection Molding: Injection Molding is a manufacturing process for producing parts in large volume. It is most typically used in mass-production processes where the same part is being created thousands or even millions of times in succession.

What is rapid injection molding?

Rapid injection molding refers to the process of making injection molds for the prototype, bridging, and short production run parts in less time and a reduced cost than full production molds. The injection molds typically made for prolonged production runs are very expensive and time consuming.

What is plastic molding process?

What Is Plastic Molding? Molding, also sometimes spelled moulding, is the process of manufacturing by shaping liquid or pliable material using a rigid frame called a mold or matrix. [ 1] When molding plastics, a powder or liquid polymer such as polyethylene or polypropylene is placed into a hollow mold so the polymer can take its shape.

What is a plastic injection machine?

A plastic injection machine is used to shape liquid plastic into solids. The liquid plastic, made of various resins depending on the desired product, is used to create a wide variety of objects and parts. The machines used to produce the plastics vary in size from very tiny to extremely large, depending on the desired end product.
