What Makes Plastic Injection Moulding Better Than Other Plastic Moulding Methods?

10 May 2022

Most parts and products nowadays are made from plastic. Manufacturers opt for plastic as one of their main materials since it is strong and long-lasting. The resistance of plastic against high pressure and extreme environment makes it likeable among manufacturers. It is also easier to process and use.

Many processes can be carried out to alter the dimensions, shapes, and other characteristics of plastic. Some intend to strengthen their durable qualities, while others are designed to alter their physical characteristics. One process, however, that many manufacturers utilise is plastic injection moulding. Plastic injection mould is the process of melting plastic pellets before they are injected into a mould cavity. As the materials fill the mould, they are solidified until the final product is produced.

A lot more processes can be used in changing the properties of plastics. But through the following qualities, manufacturers still utilise plastic injection moulding over other methods.

Increased Strength

One reason plastic injection moulding is better than other plastic moulding methods is it can provide stronger parts and components. When conducting this process, the designer would normally determine the required properties of the products before they are generated. They likewise acquire all the application details of the products before proceeding with the process. The purpose of doing these things is to ensure that the manufacturers do not produce weak and unstable plastic products.

Quick Production

Another reason why plastic injection moulding is more preferred by industries as opposed to others is it can produce products very quickly. Plastic injection moulding is the most efficient form of moulding as it can generate many products in a short time. The process does not even yield high costs despite manufacturing products in a short duration. On average, the cycle time of this process passes about 15 to 120 seconds, which depends on the complexity of the mould.

Complicated Parts

And speaking of mould complexity, plastic injection moulding is utilised by many manufacturers compared to others since it can handle and produce complex parts. Not all moulding processes can yield complicated parts. Without using the right process, industries may waste resources and generate mediocre products. Plastic injection moulding can produce complex parts in large volumes as long as the designer obtains the right part design.

Flexible Properties

Not all plastics are similar. Hence, the materials would possess colours and other qualities that will be different from one another. Fortunately, plastic injection moulding can process almost all types of plastics. The advances in polymer even enhance the flexibility of the process, allowing industries to obtain parts and products that boast not only great appearance but also stronger properties. Plastic parts out of plastic injection moulding can possess varying impact strength, tensile strength, and colours.

All these properties of plastic injection moulding allow businesses to minimise waste and save a lot of resources. To know more about this process, you can contact us at Sandabe Industries.
