FAQ
1. Product Specifications & Quality
Q: What alloy steel grades do you use for these components?
A: We typically use 4140, 4340, or 42CrMo4 alloy steels for optimal strength and heat resistance. Custom material grades can be sourced upon request.
Q: How does forging improve performance compared to cast/machined parts?
A: Forging aligns the metal’s grain structure, enhancing fatigue resistance, impact strength, and dimensional stability—critical for high-stress engine applications.
Q: What certifications do your products comply with?
A: Our production is ISO 9001 and IATF 16949 certified, with material traceability and full inspection reports (e.g., hardness, tensile tests).
2. Customization & OEM Services
Q: Can you customize dimensions or coatings for specific engines?
A: Yes! We adjust material grades, tolerances (±0.01mm achievable), surface treatments (e.g., DLC coating), and packaging per OEM blueprints.
Q: Do you provide prototype samples before mass production?
A: Prototypes are available for testing. Lead time depends on complexity (typically4–6 weeks).
3. Pricing & Logistics
Q: What’s the MOQ (Minimum Order Quantity)?
A: Standard MOQ is 1000 pieces/order.
Q: What’s the typical delivery time?
A: 30–45 days after order confirmation (varies by quantity and customization). Expedited options available.
4. Performance & Maintenance
Q: How do your balance shafts reduce engine vibration?
A: Precision-forged shafts are dynamically balanced to ≤0.5g·cm, minimizing harmonic vibrations in 4/6/8-cylinder engines.
Q: Are these fuel injectors compatible with biofuels/synthetic fuels?
A: Yes, our nitrided/chrome-plated injectors resist corrosion from E10, biodiesel, and alternative fuels.
