Advantages and disadvantages of injection moulding - Martin's ...What is injection moulding? Injection moulding is a manufacturing process for producing parts by injecting material into a closed mould. Injection moulding can be performed with a host of materials, including metals, glasses and in our case thermoset elastomers and polymers. Parts to be injection moulded must be carefully designed to facilitate the moulding process. The material used for the part, the desired shape and features of the part, the material and design of the mould, ...

3 Advantages and Disadvantages Of Plastic Injection Molding ...20 Dec 2015 ... This results in a process which becomes even more cost-efficient as the volume of the production run increases. There is very little waste in production. Not only is there a high rate of accuracy in design, but any excess material or scrap can be ground down and reused, since most plastics are recyclable. This is not only a cost-saver, but it also increases the sustainability of the process. It's highly flexible. Injection molding allows for variety in the materials and colors of ...
