Plastic Injection Moulding is one of the most prevalent methods for mass producing plastic components. The technology involves the feeding of plastic material into a heated barrel. The material is mixed and then forced into a mould cavity, where it takes the shape of the cavity and solidifies into the final product.
Plastic injection moulding has a multitude of benefits over comparative plastic processing and manufacturing methods.
Here’s a look at the top 10:
Plastic injection moulding is such a precise method that it can engineer nearly any type of plastic part. There are certain design restrictions, but the moulds that are made allow the finished product to be very exact. Accuracy can be within 0.005 inches.
There is a reason why plastic injection moulding is one, if not the most common technologies for long manufacturing runs, it’s fast. How fast? While the speed very much depends on the complexity of the mould itself, generally only about 15 to 30 seconds’ pass between cycle times.
3) Low labour costs
Injection moulding equipment usually runs with a self-gating, automatic tool to keep operations streamlined and production ongoing, thus requiring minimal supervision.
Plastic injection moulding is not only an efficient, effective process, but it is also resourceful. That’s because a) only as much plastic necessary is used to create the component part and b) excess plastic can be ground up and recycled.
Aside from being an accurate production process, plastic injection moulding is also a flexible one. It is simple to change the type of material that is being produced as well as the colour.
6) Ideal for creating high-strength component
Another benefit of plastic injection moulding is that fillers can be added to components during processing, reducing the density of the liquid plastic while adding enhanced strength to the finished part. Plastic injection moulding is an ideal process for industries or products where parts need to be robust.
7) Smooth finished appearance
Plastic injection moulding is a process, whereby produced components need little to no end finishing. That’s because all parts that come out of the mould are about the closest thing to the finished appearance.
8) Co-injection moulding
Injection moulding machines can process two or more different plastics at the same time.
9) Cheaper than plastic machining in the long-term
The initial creation of a mould can be costly, however once the mould is created you can produce a very large volume of plastic components at minimal cost. For this reason, large production runs using plastic machining can cost up to 25 times more than that of plastic injection moulding.
10) Widely used
Plastic injection moulding is one of the most prevalent plastic manufacturing processes. If you look around, you are likely to see lots of products that have been made via the plastic injection moulding process.
