I. Introduction
Most of the parts used in the engineering and manufacturing industries today are made from plastics. These parts are manufactured through a process called plastic injection molding. Plastic injection molding is a process where a plastic polymer is heated beyond its melting point, and then the molten plastic is forced (injected) into a mold which has the shape of the final desired product. Upon cooling, the plastic hardens assuming the shape of the mold resulting in the desired final part. This process uses complex machinery to ensure that the finished plastic parts meet the required quality and standards.
When looking for a plastic injection molding company for your project, you need to ensure that you select a company that will move with you all the way from the design stage to the finishing of your product. Some of the factors to consider when looking for the best plastic injection molding company in the UK are:
