Hindi karaniwang Precision Forged na Mga Bahagi

1. Automotive Precision Lane

• Closed-die hot + warm forging sa 1 600–8 000 t servo presses, 0.3–15 kg, ±0.1 mm as-forged
• Cold forging station para sa 5 mm-Ø valve seat, 150 ppm, IT7 tolerance, Ra 0.3 µm—walang chips, walang waste
• Micro-alloy steels (46MnVS5, 20MnCr5, 16MnCr5, 34CrNiMo6) + kinokontrol na paglamig → 28-35 HRC core, 1.0 mm case 58 HRC pagkatapos ng induction—tinatanggal ang quench-distortion sa high-speed crankshafts
• Karaniwang hindi karaniwang mga bahagi:
  – Offset crank-pin (±0.02 mm cylindricity)
  – Hollow na constant-velocity stub (timbang −18 %)
  – Dog-bone con-rod na may fractured-split cap (walang broach)
  – Thin-wall clutch hub, 2.5 mm web, AGMA 8 gear teeth net-forged

2. Heavy-Duty Industrial Powerhouse

• Open-die + ring-roll: 15 kg – 25 t; Ø 300 – 5 200 mm singsing, haba ≤ 8 m shafts; forging ratio ≥ 3 upang burahin ang porosity
• Alloy steels: 42CrMo4, 34CrNiMo6, 40CrNiMo, 4140/4340, 30CrNiMo8 – Q&T 28-58 HRC, Charpy 45 J @ –40 °C
• Mabibigat na hindi karaniwang mga halimbawa:
  – Boom hinge eye 350 mm ang kapal, 900 MPa yield, UT SEP 1921 C/c
  – Pangunahing baras ng pandurog 6 m ang haba, 18 t, induction fillet 55 HRC
  – Dragline ring gear Ø 4 m, AGMA 10 accuracy, alloy carburised 2 mm
  – Hydraulic cylinder head, 700 bar proof, bore chrome-plated 100 µm

3. Shared Precision Tool-Box

• 5-axis CNC: 0.8 µm Ra face, ±0.005 mm bore; deep-hole gun-drill Ø 1–40 mm
• Heat at surface: vacuum Q+T, induction harden, carburise 0.8-2.0 mm, nitriding, hot-dip Zn 40-120 µm, Geomet, chrome plate, shot-peen SA 2.5
• QA: 100 % UT/MT, 3-D CMM, magnetic particle sa radii, fatigue & impact test na-verify; ISO 9001, PED, CE, AS9100D kung saan kinakailangan

4. Bilis at Kakayahang umangkop

• Prototype forging: 7-10 araw (automotive), 10-15 araw (pang-industriya)
• Serye ng sasakyan: 3-5 linggo kasama. cold-form tool build
• Malakas na pang-industriya: 20-30 araw; i-export ang steel-frame packing, DDP global
