INSPECTION
Inspection Capabilities
Dimensional Inspection
Verify critical dimensions and features against customer drawings, CAD models, and technical specifications.
Geometric Tolerance Verification
Inspect complex features including position, alignment, and form tolerances to ensure manufacturing accuracy.
Surface & Feature Inspection
Check surface conditions, profiles, holes, and detailed features to maintain consistent part quality.
Inspection Equipment
| Equipment | Application | Inspection Capability |
| Coordinate Measuring Machine (CMM) | Complex precision components | Dimensional accuracy, geometric tolerances, and feature verification. |
| 2.5D Video Measuring System (VMS-4030F) | Flat parts and detailed features | Size, hole position, angle, and profile measurement. |

Inspection FAQs
When is inspection performed during production?
Inspection can be performed at different stages, including incoming material inspection, in-process inspection, and final inspection before shipment.
Can you inspect parts manufactured by different processes?
Yes. We provide inspection support for CNC machining, sheet metal fabrication, injection molding, casting, and other manufacturing processes.
Do you inspect every part before delivery?
Inspection methods depend on part complexity, production quantity, and customer requirements. Critical dimensions and key features are verified based on the quality control plan.
Can you provide inspection reports?
Yes. We can provide dimensional inspection reports, first article inspection (FAI) reports, and other quality documents according to project requirements.
What inspection equipment do you use?
Our inspection equipment includes Coordinate Measuring Machines (CMM), 2.5D Video Measuring Systems, and Linear Height Gauges to verify part dimensions and geometric requirements.
What inspection services do you provide?
We provide dimensional inspection, CMM measurement, video measurement, height measurement, and quality documentation for prototype and production parts.
