Changing Expansion of C&B Investments May Relate to Time

Are you tired of inconsistent fits from your C&B investment? As you know, many variables can affect the expansion and the fit of your castings — such as mixing liquid-to-water ratios, mixing speeds, and powder-to-liquid ratios. These variables commonly alter consistency. One important variable that is often overlooked when determining inconsistency is mixing time. The chart below relates to different mixing times of Bellavest SH C&B investment. It is easy to see that the difference of 20 seconds mixing can have a big difference in casting expansion and fit.

Most current vacuum mixers have built-in programmable timers making it easier to get consistent mixing times. By attaching a kitchen timer to an older vacuum mixer you can get more consistent results and bring your old mixer up to speed.
