How Vaccum Casting works: VC (Vacuum Casting) is widely used process in rapid prototyping industry, typically used for making 20 to 40 pieces of functional prototypes out of broad range of polyurethanes and other polymers available. The process starts with creation of an accurate and highly finished master model which can be created using various RP techniques e.g. SLA, FDM, SLS, CNC or existing part. This model is carefully placed in a mold box and liquid silicon rubber is poured over the master. After curing the silicon, mould is cut as per split line established and master model is removed, leaving an accurately formed cavities. Now these mould cavities are used to cast large variety of polyurethane or epoxy materials available. This allows fast production of high quality parts in a short lead time. A broad range of polyurethanes with various physical properties enable the production of prototypes to more closely mimic the functional properties of engineering thermoplastics.
