Examples of Polymers Best Suited for Injection Moulding

Injection moulding is a industrialized procedure for creating parts from elastic material. The melted plastic is inserted at high pressure into a mould, which is the inverse of the desired shape.

The mould is commonly made by mould manufacturer from metal, either aluminum or steel. It uses precision mechanisms to come up with the excellent features of your desired part. In addition to this, injection moulding is extensively used for developing different parts. This includes the smallest component to whole body panes of vehicles. 

Services offered by providers of liquid injection moulding include:

  • Design assistance
  • Bonding
  • Mould or tool making 
  • Graphics  
  • Market entry or prototype  
  • High volume production 
  • Low volume production 
  • Large part moulding 
  • Micro moulding 
  • Insert moulding 
  • Stamping services
  • Two-short injection 
  • Just-in-time capability 
  • Assembly services 
  • Packaging and shipping

The term injection moulding may be unfamiliar to most of us.  But this technology has helped in improving our lives by creating components that are difficult to be created by our hands. 

Plastic can be reshaped when it is heated. By injecting the molten plastic grains into the mould, it produces a new part. This process is widely used in big factories, mainly to manufacture parts for products. 

It saves up labor costs, minimizes errors that can be done by men, and is able to produce the same parts over a short time. It is good for mass production.

To some smaller companies, injection moulding seems  costly. This is because  it requires big investments on moulding machines.

Best Suited Polymers for Injection Moulding

Polymers can be used in elastomers, thermosets and thermoplastics. The available materials include blends of developed materials or alloys.  So product designers can select the material with the best set of properties from a wide selection. 

The common examples of polymers like phenolic and epoxy are great examples of thermosetting plastics. Polystyrene, polyethylene and nylon are good examples of thermoplastic. 

The moulds used by these moulding machines are designed by engineers. These are then made by mould-makers out of aluminum and steel to increase the durability of the moulds. The common products made by injection moulding are electrical components, bottles and milk cartons. 

With this marvelous technology, you can save labor costs. After all, people do get bored of doing redundant chores over and over again, but machines don't. For more details about injection moulding, having a research or browsing the web can be a big help.
