Plaster Casting (Rubber Plaster Mold)
Plaster Casting is the process of making cast metal parts using plaster molds as the "die".
Benefits of Plaster Casting:
- The tooling process is much quicker than permanent mold or die casting tooling processes
- Typical first article lead time is 1-2 weeks (expedited lead times are available)
- Tooling costs are lower than permanent mold and die casting tools
- Prototype to low-volume-production quantities are possible
- Cost effective manufacturing/prototyping solution for quantities of 5-1,000 EAU
- For quantities under 5, our in-house CNC machining department could also be a good fit
- Smooth surface finish - typical as-cast surface roughness of Ra 63 µinch (Ra 16 µm) - very comparable to a die cast process surface finish
- Exceptional part detail is possible - this process can capture detail as fine as a fingerprint in the metal casting
- Thin wall capabilities
- Typical wall thickness of .080"- .100”
- Capable of casting as thin as .030” (.75mm) wall thickness (depending on geometry)
- Parts requiring cores (both simple and complex) are easily done. Many investment cast parts can be manufactured using the plaster casting process
- Simple and very complex parts are achievable
- Capable of manufacturing zero draft geometries (a minimum draft angle of 1-2 degrees is preferred)
- Ability to accurately simulate mechanical, thermal, and corrosion properties typically associated with a die cast process
