Top 7 Benefits of Plastic Injection Moulding

Plastic injection moulding is the most common manufacturing process for the fabrication of plastic parts, with approximately 30% of all plastic objects completed in this way. Its origins go back to the mid 1800ís when American Inventor John Wesley Hyatt responded to a request by billiard ballmaker Pheland and Collander to produce a ball which was a substitute for ivory. Wesley Hyatt made new balls by injecting celluloid, which was the first industrial plastic, into a mould.

Plastic injection moulding has seen steady growth over the decades and has evolved from the production of combs and buttons to major consumer plastics, and items now produced in large volumes. The high quality thin walled plastic parts are ideal for casings and housings on automotive dashboards, tools and medical equipment. Here are 7 reasons why itís so popular:

Accurate

Plastic injection moulding is extremely precise and parts produced can be very intricate and detailed. Injection moulds are subjected to extremely high pressures and the plastic within pressed very tight. This means it is possible to incorporate very specific details and designs to within an accuracy of 0.005 inches. Consider that it can fabricate nearly any type of plastic part, and you soon understand its popularity.

Quick

Plastic injection moulding is quick, with minimal turnaround time for mass produced parts. Itís an automated process involving computer aided design and computer aided manufacturing which makes it extremely efficient. A typical mould can be completed in twenty to thirty seconds, saving valuable production time.

Flexibility

One of the major advantages of using plastic injection moulding for manufacturing parts is the ability to use several types of plastics simultaneously. Co-injection moulding means two compatible materials can be put into a single injection mould which can allow for increased strength.

Resourceful

Leftover plastics used in this process can be recycled. Any excess plastic can be ground up and melted over again, thus waste is kept to a minimum. Weíre all encouraged to be more environmentally friendly and resourceful, and injection moulding promotes recycling whilst minimising wastage.

Smooth Finish Appearance

Product parts are complete once they come out of the injection moulding process, so thereís little requirement to conduct any further finishing. Items have excellent surfaced finishes in a wide range of polishes and textures when they are removed from the injection moulds.

Less Expensive than Plastic Machining

The most expensive part of the injection moulding process is making the first mould, and this can take time. Once created, items can be produced in mass volume at minimal cost. Some manufacturers suggest that with large production runs, the use of plastic injection moulds can cost 25 times less than plastic machining.

Colour Flexibility

One mould can produce many variations of your product. Colour and material type are easy to change in injection moulding machines meaning its highly flexible and versatile.
