Operator and crew procedures: the small habits that double die life
Ten shop-floor habits, grouped into four routines, that separate a 40K-hit shop from a 120K-hit shop on the same die. None of them require new equipment. All of them require that the crew actually do them, every shift, and log the result.
A closed-die forge runs three shifts on the same crankshaft job, same H13 die, same press, same drawing. Day shift averages 110K hits per die before pull. Night shift averages 65K hits per die. The dies are not different. The drum of lube is not different. The metallurgy reports on the pulled dies are not different. The 45K-hit spread is entirely in what the crew does between the moment they walk in and the moment they walk out.
This lesson is about that gap. Ten habits, none of them new, none of them expensive, none of them requiring equipment the shop does not already own. The shops that hit 120K on a die that the next shop hits 65K on are not running better dies. They are running the same die through ten habits the other shop skips.
The habits group into four routines. Pre-shift, in-cycle, handoff and records, and the maintenance walk-down before teardown. Walk them in order.
