In the manufacture of plastic injection molds, the first job is to design the products to be manufactured in their various forms, and the designers work in them to give the appropriate shape to the product. Manufacturing is done with the help of computers, as they run programs that control the CNC router, as it plays an important role in the production of the mold. It is assembled to be then prepared for trial, and the completed molds are installed in the plastic injection machine, and the first sample is produced to be sent to the customer, and shipment is made upon approval of the final form.
