I am in need of a little help in the design of a gate system for a ceramic part that we are injection molding. we have tried various gates to try and elimante a cracking problem. the cracks occurs when the material flows around a core in the mold but does not "weld" at this point, after debinding and sintering a "crack" appears at this point. does anyone have any suggestions on what type of gate would help to fill the cavity better.
