ISO-Certified Quality Management System
Chiheng integrated machining quality control tools
Chiheng's metrology laboratory is equipped with cutting-edge quality control instruments certified to ISO/IEC 17025 standards.
Our precision measurement capabilities include:
• Zeiss Coordinate Measuring Machine (CMM) with accuracy of 0.1μm, enabling 3D dimensional inspection
• Mitutoyo digital height gauges (accuracy ±0.001mm) for precise vertical measurements
• Advanced surface roughness testers capable of measuring Ra values down to 0.01μm
• Digital micrometers and calipers (accuracy ±0.001mm) from leading brands like Mitutoyo and Tesa
• Thread gauge systems for both metric and imperial specifications
• Optical comparators with 50X magnification for profile inspection
• Rockwell hardness testers for material verification








Our quality assurance is powered by a team of certified quality engineers (CQE) and CMM programmers who utilize advanced measurement software for detailed inspection reports. Every component undergoes a rigorous First Article Inspection (FAI) process, with regular in-process checks following AS9100D aerospace standards. The quality control team maintains NIST-traceable calibration records for all measuring equipment, ensuring reliable accuracy. Our state-of-the-art climate-controlled inspection room maintains constant temperature (20±0.5°C) and humidity (50±5%) levels for optimal measurement consistency.
- Do you accommodate low-volume production requests?
Absolutely. While MOQ constraints are common in CNC machining, we specialize in prototype development and small-batch orders starting from 5 piece. Our agile production system ensures equal precision whether you need 50 units or 5,000.
- What payment methods do you accept?
Standard terms require 30-50% T/T advance deposit with balance paid pre-shipment.
For orders under $2,000, we offer flexible payment options:
• PayPal (3.5% fee absorbed by us)
• Credit Card via secure gateway
• Wise/Bank Transfer (No transaction fees) - What specifications are needed for instant quoting?
Accelerate your RFQ process by providing:
• Quantity Range: Projected order volume
• Technical Data: 2D drawings (PDF/DWG) or 3D files (STEP/DXF/IGES)
• Material Preferences: Metal/Plastic specifications
• Surface Finish Requirements(if any)
Prototype orders under 10 units typically receive quotes within 90 minutes.
