- Backup power generators and industrial diesel gensets.
FAQ :
1. What are the advantages of die-forged HPCR parts over cast or
machined parts?
Superior Strength: Die-forging enhances grain structure, offering
higher fatigue resistance.
Better Durability: Withstands extreme pressures (2000+ bar) and
thermal cycling.
Tighter Tolerances: Precision-fit for leak-free performance in fuel
systems.
2. What pressure ranges do these parts support?
Standard: 2000–2500 bar (operating), with burst pressure ≥ 3000
bar.
Custom high-pressure designs available upon request.
3. How do these parts improve engine performance?
Fuel Efficiency: Precise injection reduces fuel waste.
Lower Emissions: Cleaner combustion helps meet Euro VI/EPA Tier 4
standards.
Reliability: Reduced risk of cracks or leaks under high-pressure
stress.
4. What certifications do your products have?
ISO 9001, IATF 16949, and RoHS compliant.
Material test reports (MTRs) and PPAP documentation available.
5. Can you customize parts for specific engines?
6. What’s the typical lifespan of these components?
>10 million pressure cycles under standard conditions.
Lifespan depends on operating pressure, maintenance, and fuel
quality.
