FAQ
1. Why choose forged aluminum over cast or machined parts for
transmission applications?
Superior Strength: Forging aligns grain structure for 20-30% higher
fatigue resistance vs casting
Weight Savings: 35-50% lighter than steel while maintaining
comparable load capacity
Reliability: Eliminates porosity risks found in cast parts,
critical for dynamic loads
2. What alloys do you recommend for high-stress transmission
components?
7075-T73: Best for extreme loads (570MPa tensile) with good
stress-corrosion resistance
6061-T6: Cost-effective for moderate loads (310MPa) with excellent
machinability
Custom Alloys: Available for specialized thermal/chemical
environments
3. What tolerances can you maintain on forged connecting rods?
As-Forged: ±0.3mm
Machined Features: ±0.05mm (standard), ±0.02mm (high-precision)
Bore/Thread Finishes: Ra 0.8μm achievable for bearing surfaces
4. How do you ensure quality in forged components?
Process Controls:
Post-Forging Checks:
100% dimensional inspection (CMM)
Lot-sample destructive testing
Surface crack detection (dye penetrant)
5. Can you produce complex geometries like tapered or hollow rods?
Yes, our capabilities include:
Multi-directional forging for tapered profiles
Precision piercing for hollow sections
Flashless forging for near-net-shape parts
6. What surface treatments improve component lifespan?
Hard Anodizing (50-70μm): For wear resistance
Shot Peening: Increases fatigue life by 25-40%
Dry Film Lubricants: For maintenance-free joints
7. What’s your typical production lead time?
Prototypes: 2-3 weeks (including tooling)
Production: 4-6 weeks for first batch (100-1,000pcs)
High Volume: 8-10 weeks (10,000+ pcs with staggered deliveries)
