Mold Making
Mold making is the first step in the casting process and can determine how much work will need to be done on the back end of the process.
Quality at this step can save you much finishing time and deliver a better overall product. And quality starts with the right products for the right projects.
Traditionally, this process starts with a combination of an aluminum mold frame and sheets of silicone rubber . These sheets are built up under and around the metal master to be cast and then vulcanized.
Another option for this process starts with a glass or plastic mold frames and a liquid molding rubber. The object to be molded is sprued and put inside the mold frame. The liquid is added, and then the frame is vacuum-sealed.
Casting Tip: Need a molding process that allows virtually all materials to be used as master models? Look no further than thiss silicone RTV cold molding process. Use hand carved wax, milled wax, organic models, RP grown models, or metal molds.
A third option is the perfect choice for making molds of resins grown during the CAM process, finely detailed pieces, or pieces that would not react well to the heat and/or pressure of the previously mentioned processes. This Firefly Kit is capable of producing silicone RTV molds or HD casting patterns. It utilizes a hyperbaric light chamber to cure the rubber. Get great results while saving rubber, time, and expense.
During the last step, the mold is cut carefully using mold cutting blades to release the master object.
