Plastic injection moulding

Why consider plastic injection moulding

Nothing beats plastic injection moulding as a production method for producing plastic parts. It outperforms other forms of plastic moulding because the process is less complicated and more reliable. In addition, it has the versatility that intricate engineering designs require and the cost efficiency many businesses seek to keep their bottom line healthy.

Here are some advantages of using plastic injection moulding over other manufacturing methods.

Faster and more efficient production

There are numerous reasons why plastic injection moulding is the most popular and effective form of injection moulding for many businesses. One of the reasons is that the process is the quickest compared to other manufacturing methods. It is also more cost-effective and efficient, resulting in higher production output.

The speed of production, of course, is determined by the complexity of the design and the mould specifications. However, cycle time is typically between 15 – 200 seconds. Because of the short time between cycles, plastic injection moulding can produce more moulds in a shorter period, increasing both sales and profit margins. In addition, because of the high output, this method is more efficient and effective.

More complicated designs

Because injection moulds are subjected to high pressure, the plastic within the patterns is pressed and pushed deeper into the walls. Only the plastic injection moulding process can incorporate all the details into the part compared to other moulding processes. This means there are no restrictions on how much detail should be included in the design. Another vital contribution of high pressure to the process is that plastic moulding can produce intricate details without spending much money. Injection moulding allows for intricate designs while keeping the manufacturing process low-cost.

Increased strength

When planning the production of moulded parts via plastic injection, one of the factors to consider is strength. The designer must understand whether the components must be flexible or rigid to adjust them appropriately. If the designer is aware of the part’s purpose and the environment in which it will be used, they can specify the stability and strength that the product requires. Plastic injection moulding can provide the necessary balance. It is possible to add fillers in the moulds and choose the type of resin to use. Fillers can help reduce the material’s density while adding stability and strength to the product.

Colour and material customisation

The two essential elements in manufacturing parts are colour and material. When both are present, the design possibilities are unlimited. Polymers have made numerous advances in recent years. This is also the driving force behind developing a diverse range of resins. Working with an advanced injection moulding company familiar with various resins and how to use them will yield excellent results. Another advantage of using plastic injection moulding for part manufacturing is the ability to use different types of plastic at the same time using co-injection moulding. Tensile strength, impact strength, elasticity, water absorption, and heat deflection are all important factors to consider when choosing the right plastic. In addition, plastics can be coloured in various ways, each with its own benefits, properties, and drawbacks. Plastics can also be coloured using various techniques such as masterbatches, liquid colour, and pre-coloured resins.

Waste reduction

Companies are going green to demonstrate their dedication to sustainability, quality, and safety. Unfortunately, plastic is at the top of the list of materials that are losing favour. However, the excess plastic can be recycled when using plastic injection moulding. In addition, cutting-edge machinery is available to help reduce waste, packaging, and transportation.

Lower manufacturing costs

Plastic injection moulding has a low labour cost compared to other moulding processes. It can produce the required parts at a higher rate, resulting in a higher output rate. A typical plastic moulding machine is self-gating and works with an automatic tool. It also streamlines operations and allows for minimal supervision. The process is often performed by robotics and devices in automation, and the operator has complete control and management over it. It also contributes to lower manufacturing and labour costs. These can result in lower manufacturing costs for the customer. Automation is also responsible for producing precise and accurate moulds.

Contact Endres Dies & Moulds South Africa for details

Using the plastic injection moulding process ensures that the finished product requires no additional work after it is manufactured. This is because the parts ejected from the moulds are already polished. Please contact our team today for more information about our plastic injection moulding services.
