Abstract:

A mixer is disclosed including a sealed mixing chamber having an interior, and a rotating mixing bowl within the interior of the sealed mixing chamber. A stand operatively supports the sealed mixing chamber. The stand includes: a foundation, a mixing chamber base movably coupled to the foundation and positioning the sealed mixing chamber at an angle relative to horizontal, and a linear actuator system configured to move the mixing chamber base relative to the foundation in at least one linear direction. A rotating mixing head is operatively positioned and sealingly disposed within the sealed mixing chamber, the rotating mixing head rotating within the rotating mixing bowl. The mixer and a related method provide for ceramic suspension mixing with reduced cooling and possibly without cooling the suspension.

Abstract:

Vibration systems and systems including vibration systems for filling incomplete components with slurry material are disclosed. The vibration systems may include a vibration platform, and a component retention plate releasably coupled to the vibration platform. The component retention plate may include a plurality of component holders positioned on the component retention plate. Each of the plurality of component holders may receive a distinct, incomplete component in a predetermined orientation. The vibration systems may also include a motor operatively coupled to the vibration platform to vibrate the vibration platform at a predetermined frequency. The predetermined frequency may be based on characteristic(s) of each of the incomplete components.

Abstract:

An injection mold system for injecting slurry into an internal portion of an injection mold component core is disclosed. The system may include a fill clip for injecting slurry into an internal portion of an injection mold component core including a fill member for injecting slurry into the internal portion of the injection mold component core, and a latch member for removably coupling the fill member with the injection mold component core. The system may also include a fill reservoir for collecting excess slurry from the internal portion of the injection mold component core. The fill reservoir may also redistribute the excess slurry back into the internal portion of the injection mold component core.
