One the most common and recognisable plastic manufacturing processes is injection moulding. Injection moulding uses thermoplastics and most of the plastic products we use in our daily lives are made from using this process.
Injection moulding can be used to produce complicated three-dimensional parts that are both of high quality and consistency. It is well-suited to the mass production of products ranging from cell phone stands to toys.
Most injection moulding processes use thermoplastics because these can be melted and cooled many times to limit wasting material.
That said, special catalysts can be added to create thermoset plastic products during the injection moulding process like cured silicone rubber parts.
