Methods used in plastic fabrication

The types of different methods used in plastics fabrications

Plastic fabrication is still an important part of everyday life, a process which allows plastic to be changed and altered so that it can be moulded into the different forms required. With many parts of the modern world still being produced in fabric, from computer parts to fridges, televisions and even plasters, there is an urgent need for the skills involved with turning the plastic into a useable product. In Australia, many businesses still rely on plastic for parts, including gaskets and seals, and it is important for a business owner to understand exactly what type of manufacturing is best for the plastic piece that they require.

Plastic extrusion

This is a relatively familiar form of plastics fabrications, where the plastic is pushed out into thin layers, and then used to make tubes and sheets, and a range of complicated shapes. It is also the method which is used to create banners for hoardings at sports and music events. The plastic made this way is designed to be strong and durable, and also to be uniform, with no thin ends that might be weak points. This makes the plastic created in this way tougher and stronger than any other forms.

Lamination

Laminating plastic helps to give it a protective coating, and is often used by manufacturers of large amounts of goods, since it is durable, and also does not need a great deal of maintenance, so it can be run on a regular basis without having to be maintained at regular intervals. This makes it most suited to work where there is constant, repetitive movement of the plastic parts.

Compounding

Plastic which is compounded, or blended, is exactly as the name suggests a mixture of two different types of plastic material. The plastic is melted together, and then poured into a mould. This is then left to cool, so that it blends into a single, uniform piece. This type of fabrication can be used to make new varieties of plastic, and these tend to be stronger than their original materials.

Vacuum forming

One of the most complex forms of plastic moulding is vacuum forming. This is created by heating up the plastic until it is almost molten, and then pulling it into the shape required. The vacuum part is then used to keep the plastic in position, preventing it from changing shape as it cools. This type of fabrication is often used to make medical instruments, and can also make plexiglass.

If you want to know more about the different plastics fabrications, and find out which is best for your product, then you need to talk to your local plastics manufacturer.
