Manufacturing process of router’s vacuum pressure casting rapid prototype Mar 28,20 Manufacturing process of router’s vacuum pressure casting rapid prototype Vacuum casting: It refers to making silicone mold under vacuum by using the original template, pouring it with PU material under vacuum, so as to clone the same copy of the original template. Advantages : The time is fast and cost us little, the processing failure probability is small and so on. Production steps of router rapid prototype: Step1: Processing the prototype with CNC or 3D printing. Step2: Surround the prototype with a board, and prepare the hardener for mould the next step. Step3：Using an oxygen extractor to remove the bubbles of the prepared liquid silica gel. After 15 minutes, pour the extracted liquid silica gel into the mold surrounded by a board, cover the prototype completely, and place it for 7-8 hours for the silicone mold to solidify. Step4: Put the solidified mold into the oven and bake, so as to speed up the curing of silicone mold. Step5: Taking the prototype out of the silicone mold. Step6: According to the customer’s requirements the material is poured into the oxygen extractor to copy the product. Step7: After 30 minutes of oxygen extraction, put the mold into the pressure bar to press off the air to prevent bubbles. Step8: Putting it into the oven after the completion of pressing oxygen to accelerate the curing process. Step9: Product drying completed.
