My team is currently tasked with specifying dimensions for a twenty year old tool under reconstruction. We are only just beginning to put GMP in place where tribal knowlege had ruled. A 1980 tool print calls out a .035 diameter sub-gate with typical geometry. Original design personnel are history and this six cavity tool with two, 180 deg. opposed gates per cav. has a range of openings .053-.078. A co-relation has been shown between those cavities with the largest gates to be most prone to failure in a test mode designed to expose susceptability to linear cracking of the glass-filled nylon parts. Processing data for previously acceptable parts does not exist. We had been wingin' it. Any suggestions that would lessen our trial/test/repeat steps would be greatly appreciated. Thanks. May the Force be with you. :-)
