Methods of Plastic Fabrication


In your day to day activities, you are surrounded by products that are the result of plastic fabrication. Plastic fabrication is readily used for various types of items and is now more frequently used compared to the likes of glass or metal. This is because plastic can be manipulated for shapes and sizes much easier, whilst also being a more durable type of material to use than glass (depending on how it has been fabricated). Here are the different methods of plastic fabrication available to acrylic plastic manufacturers nowadays.

Plastic Extrusion – The method of plastic extrusion is well known for being used to construct the likes of tubes, pipes and sheeting parts in various shapes and sizes. There are commonly two forms in which the method of plastic extrusion is carried out: profile extrusion and sheet extrusion.

Both forms are extremely similar. The process consists of using one screw extruder to then melt plastic pellets. From there, molten plastic is transferred through a mechanism that is pressurized. For profile extrusion, the molten plastic is then pried into an annular die where the molten plastic solidifies around a sleeve to create shapes like tubes or pipes to a bespoke fabrication. Differently, with sheet extrusion they are solidified to create different forms of sheeting (depending on the customers requirements).

Plastic Foaming – The method of plastic foaming tends to be used in the manufacturing of insulation for industries like construction. It will usually consist of using polystyrene and/or polyurethane being used to form products such as solid plank or bun stock forms.

This process of moulded plastic fabrication usually consists of chemical blowing the materials into the shape or size that you desire, then incorporating additives to make it resistant to the likes of fire.

Plastic Welding – The method of this is much like the welding of metal; plastic welding or moulded plastic fabrication uses heat to its advantage in binding two plastics together.

This method will tend to use thermoplastics in the process, joining them together (usually with some kind of filler material). The types of welding that tend to be used in plastic welding are ultra-sonic welding, speed tip welding, contact welding and high-frequency vibration welding. The use of thermoplastics is due to the fact that they cannot be fused through the use of adhesives.

Plastic Lamination – The method of plastic lamination consists of adding a protective layer to your bespoke fabrication. This will usually be done to an acrylic plastic design, plastic design or actually many types of materials to add style and toughness to the design, especially whereas the product may be able to easily break. Examples of materials that plastic lamination can be done to are foam, paper and metal sheets.

The process for this method will tend to consist of putting pressurised heat onto a film that will then be placed over the layer of material to be covered. Of the two types of plastic lamination that can be done (film and resin), film is better for creating a protective cover on the outside of a material, whilst resin is more effective through playing a lamination layer between two different materials.

Compounding – The method of compounding consists of plastic fabrication through binding two types of plastic into a single product through forming them into a bespoke shape or size. Compounding uses moulding and heating methods to reach melting point.

The combining of two plastic materials means the chance to also combine the strengths of both metals, therefore creating a consolidation that makes a new product that is stronger and more effective than when the materials were not connected. Compounding is commonly done to form compound plastics such as base resins and pigment master batches to name a few.
