Vacuum castings are precise replicas of the patterns, dimensionally accurate without blemishes, with all profiles and textures faithfully reproduced.
The process includes nine steps:
1.The first step is to produce a pattern using any of the available RP processes (SLA, SLS, FDM, etc.)
2. The pattern is fit with a casting gate and set up on the parting line, and then suspended in a mould casting frame.
3. Once the two-part silicone-rubber is de-aerated and then mixed, it is poured into the mould casting frame around the pattern.
4. The mould is cured inside a heating chamber.
5. The pattern is removed from the silicone mould by cutting along the parting line.
6. The urethane resin is measured, dye is added for coloured components and casting funnels placed. Then, the mould is closed and sealed.
7. The computer-controlled equipment mixes and pour the resin inside the vacuum chamber. Because this takes place in a vacuum, the mould is filled completely without leaving any airpockets or voids.
8. After casting the resin, the mould is moved to the heating chamber for two to four hours to cure the urethane part.
9. After hardening, the casting is removed from the silicone mould. The gate and risers are cut off to make an exact copy of the pattern. If required, the component can be painted or plated.
Vacuum casting is an alternative technique for the production of prototype castings which mimic injection moulded parts such as ABS, PP, PMMA, PA and different grades of rubber. Using the MCP Heated Cup Module, complex, accurate wax models for investment casting can be produced.
