The unique mixer blade design unfolds the investment slurry under vacuum as it mixes. Since the unit is mixing under vacuum, air entrapment is reduced to virtually zero. Both upper and lower stainless steel chambers are vacuum sealed. The stainless steel turntable below is used to position each flask beneath the pouring valves before releasing the investment. Since the mixing and pouring of the silica powder are done inside the chamber, the exposure to dust is minimal to the operator, as well as providing a cleaner work environment.
