PAGE 1/1 ZAPP TOOLING ALLOYS INC. | CASE STUDY BLANKING PUNCH TOOL TYPE Blanking punch WORK MATERIAL .113" thick High Strength Low Alloy (HSLA) PROBLEM IDENTIFICATION D2 (Rc 60–62) was chipping at the corners after 700 hits resulting in unscheduled downtime, lower production and higher tooling costs. Most narrow point on the part is .143", so a difficult die design. Additional materials were investigated with these results: _ K340 (Rc 58-60) 2,150 parts _ Vanadis (Rc 58-60) 2,340 parts _ Z-Wear PM (Rc 60-62) 3,000 parts _ Caldie (Rc 58-60) 4,500 parts SOLUTION Z-Tuff PM RESULTS Zapp’s Z-Tuff PM (Rc 58-60) successfully ran 17,500 parts before requiring resharpening. Production levels improved dramatically and tooling costs were reduced. TOOLING A
