Dear sleeprcmaro,

I suggest taking a look at your mixing procedure. Improperly mixed injection molding material will have areas of low and high wax concentrations, which means a not uniform binder removal/burnout. The next thing would be the ceramic particle packing. There are additives you can mix with the ceramic lower surface tension, and allow for better mixing.
