Quality Assurance

Quality control is a fundamental responsibility of everyone at HONGFEI

Quality control is more than a final inspection

Before production of any new or modified item, our sample procedures ensure that the casting will meet Zhejiang Hongfei Machinery Manufacturing Steel’s quality standards. Sample castings receive some or all of these quality tests, as appropriate:

  • Compositional analysis
  • Inspection for flaws or discontinuities
  • Dimensional checking
  • Hardness testing
  • Radiographic analysis
  • Ultrasonic testing
  • Magnetic particle inspection
  • Die penetrant inspection
  • 3D scanner
Metallographic analysis
liquid penetrant testing(PT)
Dimensional checking
Mechanical and hardness analysis
Compositional analysis
3D scanner

We evaluate wear part quality based on casting structural integrity, alloy selection and formulation, heat treatment, and dimensional accuracy of assembly and working surfaces. Once a sample part is tested and approved, its production continues to receive scrutiny by our Quality Assurance Department.

Product performance tracking, manufacturing documentation, and our own high production standards mean our parts are guaranteed for proper fit, performance and customer satisfaction.
