This process is used to produce a short production run or duplicated products, using the part produced via CNC, or SLA as a master to produce a silicone rubber mold. This silicone rubber mold is used in vacuum casting machine to produce accurate duplicate of original products. RTV equipment has several advantages including high production speeds, good accuracy (including the surface finish) and much lower costs. We are able to duplicate the product in a range of different materials, ABS, clear PC, PMMA, PP, PA simulant, etc.
We have 4 Vacuum Machines with a maximum size of 1200mmx800mmx800mm
Silicone tool – liquid silicone is poured around the master model and cured. Once dry the master is cut from the mold to leave the cavity
Castings – the resin is poured into the cavity to create a production like replica
Advantages of Vacuum Casting
Great for low volumes
Self-coloured parts
Low upfront investment
Production like parts
Massive range of materials
Rubber like parts and over molds
Used for
Low volume prototypes, low volume production, rubber parts, market testing, rapid iterations
