A Polish converter cutting 12 µm BOPP film at 600 m/min was burning through 4 D2 slitters per week. The fix was a 2-week field audit, a steel-grade change, an edge-prep change, and a coolant-nozzle relocation. This case study walks through the diagnostic, the trial, and the result — a 6× service life improvement that paid back the entire project cost in 11 weeks.
AISI D2 and JIS SKD11 are the most-quoted cold-work tool steels in industrial blade manufacturing. They share a spec sheet — but the heat treatment, dimensional consistency and field performance are not identical. Here is the engineering comparison.
A slitting blade is the most-asked-about consumable on a converting line. The life of the knife is set by the substrate, the steel grade, the edge prep, the heat-treat quality and the in-process care — not by luck. This maintenance guide walks through the seven variables that actually drive service life.
A structured method our engineers use to match substrate, geometry, hardness target, edge preparation and operating speed to a production line — without second-guessing the steel grade.
