Quality Assurance
Zhendong understands that CNC machining quality is not only about producing parts, but ensuring every component consistently meets customer requirements.
We follow a strict ISO 9001:2015 quality management system across all prototyping and machining processes. From initial design to final inspection, each step is governed by standardized procedures and advanced testing equipment to ensure consistent quality, continuous improvement, and customer satisfaction.
Precision Measuring Tools
We use a comprehensive range of precision measuring tools to ensure every part meets strict dimensional and quality standards. Our key inspection equipment includes:
-
Granite Surface Plates: 1000×750 mm
-
Digital Height Gauge: Measuring range 0–600 mm
-
Full-Range Vernier Calipers: 0 –100 / 150 / 200 / 300 / 600 / 1000 mm
-
Micrometers (Outside & Inside): 0–25 / 75 / 100 / 125 / 150 mm and 12–20 / 50 / 100 mm
-
Pin & Plug Gauges: 0.5–12 mm / 1.0–100 mm, pitch interval 0.01 mm
-
Surface Roughness Meter & Hardness Tester
Built on a Proven Quality Management System
Our operations are guided by standardized management principles, lean production methods, and a strong commitment to environmental responsibility—ensuring high-quality outcomes at every stage.
VMM Optical Measurement Inspection
Zhendong uses a VMM (Video Measuring Machine) for accurate measurement of complex part features
VMM inspection is suitable for:
-
Precision profiles
-
Hole positions
-
Contour measurement
-
Small components
-
Complex 2D features
-
DFM Review – Ensure designs are optimized for manufacturing.
-
Order Confirmation – Double-check contracts and specs.
-
Production Planning – Align capacity with delivery timelines.
-
Material Inspection – Verify incoming raw materials.
-
In-Process Checks – Monitor parts during production (IPQC).
-
Non-Conformance Handling – Apply corrective and preventive actions.
-
Final QC & Reports – Deliver full inspection and certifications (OQC).
-
Customer Feedback – Conduct satisfaction surveys twice a year.
