Vacuum Casting

The Vacuum Casting ensures the production of a limited number of pieces (1-25) in a material that is very similar to the final for physical characteristics mechanical and aesthetic properties. It starts from a master which is usually made ​​of stereolithography or Polijet which is appropriately suspended in a container. After placement of vents and sprues is coated with liquid silicone previously degassed. At the end of the process, the mold is placed in a special oven for curing. The mold is then cut into two or more parts to obtain a subsequent perfect coupling. The available materials are similar to the more commonly used as Simil rubber (30 to 90 ShoreA) PP, ABS, PC, etc. ..
