Advantages Of Vacuum molding                                                                      Low cost for molds Molds can be made in a few days Many types of polyurethane resins are available for casting, including overmolding Cast copies are highly accurate with excellent surface texture Molds are durable for 20 or more copies Perfect for engineering models, samples, rapid prototypes, bridge to production Vacuum Casting Process Prototype Making Before making the silicone mold, Need a Prototype for mold that can be done by 3D Printing or CNC Mold making Fill the liquid silicone into the casting box, heat the casting box unit it is fully cured,then put into the oven to cure. Fill with extra silicone liquid which is also heated&cured. Once it dried, cut open the silicone mold and remove the sample Make the part Finally, poured the resin into the empty cavity to create a copy of the original.The mold can be used for the next production cycle.
