I-customize ang Forged Wheel Hubs Automotive

1. Closed-Die Hot Forging Platform

• Saklaw ng pagpindot: 1 600 t – 10 000 t servo-hydraulic, 1-2 cavity family tools
• Timbang ng bahagi: 0.3 kg – 65 kg; OD ≤ 500 mm; taas ≤ 250 mm
• Katumpakan: ±0.25 mm as-forged, machining allowance ≤ 1 mm bawat gilid (makatipid ng 25 % cycle time)
• Forge ratio: ≥ 3, full fiber flow sa paligid ng spoke windows → 30 % fatigue gain vs. cast wheel

3. Mga Tampok ng Net-Shape na We Forge-In

• Spoke window, bolt hole, bearing seat, ABS tone-ring pocket – napeke sa ±0.2 mm, drill-tap time cut 40 %
• Nagsalita ang swept-back para sa clearance ng brake-caliper – walang pangalawang paggiling
• Mga nagpapagaan na bulsa sa likurang bahagi – timbang –12 % kumpara sa machine-from-solid
• Integral spline o key-way – cold-coin pagkatapos ng hot forge, Ra ≤ 1.6 µm

4. Post-Forge Finishing

• CNC turning at milling: 5-axis, run-out ≤ 0.02 mm; bolt-circle ±0.05 mm
• Induction harden: bearing journal 55 ±2 HRC, depth 4-6 mm; fillet compressive stress –180 MPa
• Ibabaw: cathodic e-coat 20 µm + powder top 60 µm, Geomet 320, hard-anodise (Al), polish at brush (SS) – 720 h salt-spray
• Balanse: single-plane ≤ 5 g-cm; twin-plane para sa mga hub ng trak na ≤ 10 g-cm

5. Pagpapatunay at Sertipiko

• Dynamic na bend test: 2 × 10⁶ cycle @ ±3 kN, walang crack ≥ 2 mm
• Epekto: 27 J @ –40 °C para sa 42CrMo4 hub; 45 J para sa duplex stainless
• Porosity: 100 % UT ASTM A388, SEP 1921 Class C/c; 3-D CMM sa bolt pattern
• Mga Pamantayan: IATF 16949, ISO 9001, SAE J175, OEM PPAP level 3

6. Mabilis, Flexible na Supply

• Prototype (forged + machined): 10–12 araw
• Serye 5 k–200 k/yr: 4–6 na linggo kasama. pagbuo ng tool
• Export packing: VCI + EPE + plywood pallet; DDP global, 5-araw na air freight na opsyon
