Vacuum Casting

Process Description:-
Vacuum Casting is a process used to produce multiple components from a single master model in materials that closely mimic many production plastics. A liquid RTV Silicone rubber is used to encapsulate the master (normally an SLA model), and then once cured, cut open to create the mould tool. The mould is then placed under vacuum, where a 2-component Polyurethane resin is used to fill the cavity and create the casting.
