Jolin Mao is a Development Engineer at Aunov with 20 years in new product development for metal deep-drawn and precision stamped parts. He owns the full cycle from customer drawing review and DFM analysis through process design, tool development, sampling and NPI transfer. His scope includes DFM risk prediction, draw-route design, in-house tooling coordination, first-article validation, PPAP/FMEA/control-plan documentation, and closing loop on trial and mass-production defects.
Direct answer: This is a real, anonymised PPAP Level 3 package for a welded 316L stainless sensor tube, 106 mm long with a Ø4 mm ground outside diameter. Nine process steps, nine inspection characteristics on five pieces (45 checks, all accepted), a leak test at 8 bar, gauge R&R of 19.0% of study variation, and…
Precision NTC Ring Terminal SUS304 ring terminal for a European NTC temperature-sensor programme — anonymised PPAP summary. Direct answer: AUNOV produces this 0.25 mm SUS304 ring terminal with a Ø3.2 mm mounting hole on an eight-step route — blanking, stamping, punching, four-hour vibratory polishing, then 100% appearance and sampled dimensional inspection. The PPAP first article passed all…
Blind-Hole Sensor Housing 304 stainless steel pressure/temperature sensor shell — one draw plus ironing. Direct answer: AUNOV draws this 304 stainless steel sensor housing in a single draw on a 200 T press, then irons the wall from 0.8 mm to 0.62 mm to hold ±0.05 mm, with a sealed blind bottom that leaves no leak path. Material 304…
Prismatic Cell Can 5052 aluminium battery can — 0.15 mm wall, multi-stage draw. Direct answer: AUNOV draws 5052 aluminium prismatic cell cans to a 0.15 mm wall and up to 110 mm depth using multi-stage drawing with inter-stage annealing, sized from the measured 5052 limiting draw ratio of 1.80–1.95. Material 5052 aluminium Wall thickness 0.15 mm Draw depth…
316L Implantable Enclosure Small sealed 316L stainless steel capsule for a sterile electronic implant. Direct answer: AUNOV deep-draws this 316L stainless steel implant capsule in a single draw plus light ironing to a 0.4 mm wall and 24 mm depth, holding ±0.05 mm with a clean internal surface and no internal burr. Material 316L stainless steel Draw depth…
Hinged Military Case Zinc-plated DC04 rectangular draw with a formed hinge flange. Direct answer: AUNOV draws this DC04 steel military case as a rectangular shell to 90 mm depth and 1.2 mm wall, then restrikes to hold flange flatness for the lid seal, sized from the measured DC04 limiting draw ratio of 2.1–2.2. Material DC04 steel Draw…
EMI Shield Can Thin 5052 aluminium shield with fine walls and formed tabs. Direct answer: AUNOV produces this 5052 aluminium EMI shield as a shallow draw to 8 mm depth and 0.2 mm wall, pierced in the same tool, holding ±0.05 mm with no spring-back mismatch across the walls. Material 5052 aluminium Wall thickness 0.2 mm Draw depth…
Stainless Pressure Cup 304 stainless steel pressure-vessel end, deep-drawn then ironed. Direct answer: AUNOV deep-draws this 304 stainless steel pressure-vessel end to 120 mm depth, then irons the wall from 1.0 mm to 0.78 mm to hold ±0.02 mm with minimal out-of-round for a pressure-rated part. Material 304 stainless steel Draw depth 120 mm Wall thickness 1.0 → 0.78…
