Injection molding is a manufacturing process for  producing parts by injecting material into a mold. In injection  molding process,both injection mould and inejection machin â¦ e will be  used. Injection molding is for producing plastic products, such as  chairs, tables, pipe fittings, etc.njection molding plastic is a tool used to mold hard material through thermal heat, for example steel or aluminum are not metals that could be heated using the tool which mak â¦ es the material easier to manipulate or mold into varies of shapes.
