Quality Policy

Our Quality Commitment

At Ming Hong Industrial, we firmly believe that quality is the core competitiveness of our enterprise. We uphold a quality policy of "Precision Manufacturing, Stable Quality, and Continuous Improvement." From raw material inspection and production processes to final shipment, we implement rigorous checks at every stage to ensure every product meets our customers' strict standards.

We understand that every micron of precision impacts product performance and safety. Therefore, we continuously invest in precision measurement equipment and inspection technology, implementing comprehensive ISO 9001 and IATF 16949 quality management systems. Combined with a systematic quality management framework, we build a highly reliable and stable product supply capability.

🛡️ Professional Systems・International Certifications

We are certified for:

  • ISO 9001: Quality Management System — Ensuring every process and procedure is documented and traceable.
  • IATF 16949: Automotive Quality Management System Standard — Meeting the high-reliability production requirements for automotive and motorcycle components.

We also ensure our quality control processes are predictable and consistent through continuous internal audits and improvement.

🔬 Measurement & Inspection Equipment Capabilities

We possess over 600 units of professional measuring instruments and gauges across more than 50 categories, covering geometric dimension inspection, material hardness testing, surface treatment verification, and microstructural analysis. This allows us to meet every quality assurance requirement, from incoming material inspection (IQC) and in-process control (IPQC) to final shipment (FQC):

Dimensional Accuracy Control

  • Coordinate Measuring Machine (CMM) (CRT-AC9106)
  • Roundness / Surface Roughness Testers (RA-2100AS, SJ400, SJ210)
  • Profile Projectors, Inside/Outside Micrometers, Dial Indicators, and various standard gauges (caliper gauges, height gauges, ring gauges, thread gauges, etc.)

Material & Strength Testing

  • Universal Strength Testing Machine (HT-9102)
  • Friction Tester, Tension Gauges (Push-Pull Gauges), Standard Weights
  • Hardness Testers (Rockwell, Brinell), Salt Spray Tester (SH-90)

Surface Treatment & Environmental Testing

  • Coating Thickness Gauges (various models), pH Meter, Gloss Meter (HORIBA)
  • Thermometers and Controllers, Infrared Thermometer, X-RAY Inspection Instrument

Specialized Inspection Equipment

  • Spectrometer (SPECTROMAXX), 3D Profile Measurement System (VR-6200)
  • Oven Temperature Tracker, Bubble Level, Electronic Scales, and Digital Salinometer

Furthermore, for precision products and mass-produced parts, we can provide quality assurance documentation, including First Article Inspection (FAI) reports, customer-specified inspection checklists, and incoming/outgoing inspection records, ensuring fully traceable quality assurance.
