At CHIHON MACHINERY, quality isn't just a promise – it's the core of everything we do. For over 30 years, we've been committed to delivering brake components that don’t just meet industry standards but exceed them. Every part we produce is a result of precise craftsmanship, advanced technology, and a relentless focus on quality.

Our Quality Control Process: Excellence in Every Step

1. Rigorous Raw Material Selection

Our quality journey begins with the careful selection of premium materials. We use FC250 cast iron (also known as Grade 250 Cast Iron, GG25, or Class 250 Cast Iron) – a material known for its exceptional strength, durability, and performance under stress. We don’t just accept materials at face value – every batch is tested for durability and consistency, ensuring it’s ready to perform under demanding conditions.

2. Precision Machining & Balancing

Our commitment to precision starts with state-of-the-art machining technology. Every component is manufactured to exact specifications, and we employ advanced balancing techniques to ensure each part performs safely and reliably. Whether it’s for OEM customers or the aftermarket, our precision ensures optimal performance, safety, and longevity.

3. Advanced Surface Finishing

To provide brake components that stand the test of time, we utilize cutting-edge surface finishing technologies. Our process not only enhances corrosion resistance and wear properties but also optimizes friction control. The result? A product that can withstand the harshest environments and provide dependable performance throughout its lifespan.

4. Comprehensive Final Inspections

We don’t just rely on automated machines – our final inspection is a hands-on process, conducted by skilled technicians who understand the importance of every detail. Each product undergoes rigorous testing for:

  • Dimensional accuracy: to ensure every component fits perfectly.
  • Stress testing: simulating real-world conditions to verify durability.
  • Consistency across batches: every product we ship is as reliable as the last.

We don't just meet the standards – we set them.
