FAQ :

1. Why choose die-forged over cast/machined common rail parts?

• Structural Integrity: Die-forging aligns grain flow with part geometry, achieving 30% higher fatigue resistance

• Performance Under Pressure: Withstands 3000+ bar burst pressure (vs. 2200 bar typical for cast parts)

• Longevity: Proven 1.5-2x service life in field tests with European truck fleets

2. What pressure ranges do your components support?

• Standard Series: 2000-2500 bar operating (3000 bar burst)

• High-Performance Series: Up to 3000 bar operating (3500 bar burst) for marine/mining applications

• Custom pressure profiles available with advanced FEM analysis

3. How do your parts help meet emission regulations?

• Precision Matching: ±0.5% fuel flow consistency enables:

  • Euro 6d/China VI compliance

  • EPA Tier 4 Final particulate thresholds

• Biofuel Optimized: Special grades available for B100/FAME compatibility

4. What certifications accompany your products?

• Quality: IATF 16949, ISO 9001:2015

• Material: EN 10204 3.1 mill certificates

• Environmental: REACH/RoHS/IMDS data

5. Can you match OEM specifications exactly?

• Yes, we provide:

  • Reverse engineering for discontinued parts

• Case Example: Successfully replicated MAN D2676 rail with 15% weight reduction

6. What's your lead time for custom orders?
