The investing procedure remains the same for vacuum mixing and conventional hand mixing using the same standard equipment currently used in any jewellery manufacturing operations.
The Water / Powder ratio recommended for best results is between 36 – 38 parts water to 100 parts powder (36-38:100) for machine mixing or between 38 – 40 parts water to 100 parts powder (38-40:100) for hand mixing.
Burnout cycle remains the same as regular investment powder, meaning casters do not have to modify any burnout procedure. Can be used in all current burnout furnaces.
