Popular and highly versatile, Injection moulding is a manufacturing method used to produce mass-produced plastic parts. The process produces items by injecting molten plastic into a pre-produced mould.  But why is injection moulding so sought after and what are the advantages of using this method?

  1. Complex shapes and small details

Injection moulds are subjected to high pressure, which means that the plastic within the moulds is pressed against the mould with greater force compared to other moulding processes. This high pressure enables the incorporation of specific features and complex geometry into the design. Injection moulding is well suited to creating parts with complex and intricate shapes, which would otherwise have been too complicated and expensive to produce.

  1. Variety of plastics

Injection moulding machinery is suitable for use with a variety of plastic types. Manufacturers can easily change the kind of material and the colour of the product produced. Co-injection can integrate more than one type of plastic into the product during production, adding versatility and flexibility to this type of machine’s list of attributes.

  1. Strength

Strength is a critical consideration when designing a plastic part. Plastic injection moulding allows the use of fillers in the injection moulds. Fillers reduce the density of the plastic and add greater strength to the piece after it has been moulded. This is invaluable for fields that require parts that are strong and durable.

  1. Reduced waste

Environmental concerns remain a priority for many manufacturers. Injection moulding enables manufacturers to re-use the scrap plastic generated during the production process, ensuring that little goes to waste.

  1. High speed

Injection moulding popularity can be partly attributed to quick production speeds. The production speed can differ based on the mould and the machine type, but the general time between cycles is between 15 and 30 seconds.

  1. Inexpensive

The starting costs can be high, as the machinery may be pricey, but the running costs are minimal. Once you have a mould, you can create a high volume of plastic components at low cost. Injection moulding also saves in labour costs, as the machinery generally runs on a self-gating automatic tool; keep operations streamlined and requiring very little supervision.

Injection moulding offers manufacturers a process that is quick and efficient, creating parts that require barely any work after production, are strong and have great detailing. This manufacturing method facilitates a wide range of design options and material options, and it is commonly used to produce items such as packaging, bottle caps, automotive parts and more!
