Our Quality Inspection Process
Quality Control Throughout Production
Pre-Production
Before production begins, our engineering team conducts a detailed review of your design. This includes evaluating materials, surface finishes, structural integrity, and processing requirements based on your 3D and 2D drawings.
- DFM Analysis
- Material Verification
- Process Planning
In-Production
During the production process, our quality control team conducts regular inspections to ensure that each product is manufactured according to precise standards and SOPs.
- Real-Time Monitoring
- In-Process Inspections
- Process Validation
Final-Production
Upon request, we provide a comprehensive dimensional inspection report for every order. This includes critical measurements, threads, tolerances, material thicknesses, depths, and part appearance to confirm the final product meets your exact specifications.
- Dimensional Inspection
- Surface Finish Evaluation
- Functional Testing

Why Choose Us for Quality Control
Visual Inspection
We inspect each product's appearance, verifying that it meets your standards for color, texture, and overall finish. Our team ensures that there are no visible defects, ensuring the product aligns with your expectations.
Dimensional Inspection
We use tools like vernier calipers, micrometers, and CMM to perform detailed dimensional inspections, ensuring each part meets the specified measurements, including hole sizes, depth, and other critical features.
Performance Inspection
We test the functionality of components to ensure they work as intended. For example, threaded holes are checked to ensure they align and fit during assembly. This step ensures the parts will function seamlessly in their final application.
First Article Inspection
Before mass production begins, we perform a thorough First Article Inspection (FAI). This report documents all inspection processes and results, ensuring the first batch meets all design requirements before full-scale production.
