There are a range of processes involved in the manufacturing of plastic products.
Injection moulding
Injection moulding is a manufacturing process that is commonly used to create a multitude of plastic products. The process is similar to die casting metals. Molten plastic is injected under pressure into a cavity mould and then cooled. The process is popular because it can produce large volumes of complex shapes and components easily, cheaply, and efficiently.
How injection moulding works
3D Printing
3D printing is a relatively new technology. A model or template for object to be created is first scanned or recreated in computer-aided design software (CAD). This information is relayed to the printer which builds up shapes by melting plastic and printing it in layers while in liquid form to create a three dimensional object.
