The mixing of the Investment Powder is vitally important to producing a air bubble free casting with a high quality surface finish.

Gold Star Maxivac Vacuum Mixing Machines provide consistent mixing, leading to a superior surface finish, total elimination of air bubbles and highly accurate pouring, ensuring no wax breakage.

Gold Star's Maxivac 17 and 35 vacuum mixing machines are specified to the exacting conditions required for optimum results of the Investment Powder. The vacuum mixers do this by improving the consistency and quality of the mixed slurry through the reduction of air entrapment, and wetting of the powder during the mixing and pouring process.
