The client needed 250;000 units per year of small (65mm \u00d7 38mm \u00d7 12mm) stamping brackets for a reusable surgical instrument sterilizer rack.
. <\/p>\n\n\n\n

The bracket held critical alignment pins and was exposed to:
<\/p>\n\n\n\n

 Daily autoclave sterilization (steam at 134\u00b0C \/ 273\u00b0F; high humidity).
.<\/p>\n\n\n\n

Hospital grade disinfectants (bleach and quaternary ammonium compounds).
.<\/p>\n\n\n\n

 Physical impact from repeatedly loading heavy surgical trays.
.<\/p>\n\n\n\n

The original part was machined from solid 316L bar stock.
. <\/p>\n\n\n\n

While functional; machining had three major problems:
<\/strong><\/p>\n\n\n\n

Cost:<\/strong> $4.20 per unit (too expensive for a semiconsumable bracket).
.<\/p>\n\n\n\n

Lead time:<\/strong> 8 weeks for 5;000 units (machining was too slow).
.<\/p>\n\n\n\n

Material waste:<\/strong> 65% of the 316L bar was turned into chips and scrap.
.<\/p>\n\n\n\n

MT requested: stamping brackets alternative at \u2264$1.80 per unit; with zero porosity; corrosion resistance equal to machined 316L; and a smooth; cleanable surface (no crevices for bacterial growth).

The Flow Wing Metal Execution
<\/strong>:<\/p>\n\n\n\n

Step 1: Design for Stamping (DFS) Engineering
<\/strong><\/p>\n\n\n\n

Flow Wing Metal\u2019s engineering team reviewed the 3D model and redesigned the stamping brackets:
<\/p>\n\n\n\n

 Material change removed: Replaced machined bar with 1.2mm thick 316L stainless steel coil (fullhard temper for springback control; then annealed poststamp).
.<\/p>\n\n\n\n

 Geometry optimization: Added 0.5mm fillets to all internal corners (previously sharp 90\u00b0) to prevent stress cracking during forming.
.<\/p>\n\n\n\n

 Hole tolerances: Specified punched holes at +0.05mm \/ 0.00mm for precision pin alignment (achievable with fineblanking techniques).
.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Step 2: Tooling Fabrication
<\/strong><\/p>\n\n\n\n

 Die type: Progressive die with 8 stations.
.<\/p>\n\n\n\n

 Die material: Powdered metallurgy tool steel (CPM 10V) with titanium aluminumnitride (TiAlN) coating for wear resistance against workhardening 316L.
.<\/p>\n\n\n\n

 Press: 200ton Bruderer highspeed stamping press.
.<\/p>\n\n\n\n

 Stations included:
<\/strong><\/p>\n\n\n\n

Pilot hole piercing<\/p>\n\n\n\n

Main hole piercing (\u00d74)<\/p>\n\n\n\n

Lancing: partial cut for clearance feature<\/p>\n\n\n\n

First 45\u00b0 bend<\/p>\n\n\n\n

Second 90\u00b0 bend<\/p>\n\n\n\n

Coining: flattening of mounting surface.<\/p>\n\n\n\n

Blanking: part cut from carrier strip<\/p>\n\n\n\n

Scrap cutoff<\/p>\n\n\n\n

<\/p>\n\n\n\n

Step 3: Process Development & Testing
<\/strong><\/p>\n\n\n\n

 Trial run: 500 parts produced using mild steel (for die validation).
.<\/p>\n\n\n\n

 Stainless trial: 1;000 parts in 316L with specialized chlorinated extremepressure stamping lubricant to prevent galling.
.<\/p>\n\n\n\n

 Adjustments: Increased press speed from 40 to 55 SPM (strokes per minute); added air blast to clear small slugs from piercing stations.
.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Step 4: Post Stamping Brackets Operations
<\/strong><\/p>\n\n\n\n

 Degreasing: Automated threestage spray washer (alkaline wash \u2192 rinse \u2192 rust inhibitor rinse).
.<\/p>\n\n\n\n

 Deburring: Light vibratory tumbling with ceramic triangles (15 minutes) to remove punchentry burrs (<0.05mm remaining).
.<\/p>\n\n\n\n

 Passivation: Citric acid bath (20% concentration; 25 minutes at 55\u00b0C) to restore chromium oxide layer \u2013 critical for autoclave resistance.
.<\/p>\n\n\n\n

 Inspection: 100% go\/nogo gauge for pin holes; laser micrometer for bend angle tolerance (\u00b10.5\u00b0).
.<\/p>\n\n\n\n

<\/p>\n\n\n\n

 Cost savings: 64% reduction per unit ($4.20 \u2192 $1.52) = $670;000 annual savings for the client.
.<\/p>\n\n\n\n

 Production speed: From 8 weeks for 5;000 units (machined) to 2 weeks for 25;000 units (stamped).
.<\/p>\n\n\n\n

 Material utilization: Increased from 35% (machined) to 82% (stamped from coil).
.<\/p>\n\n\n\n
