Quality Assurance

Our Quality Assurance Process

At GBM, our comprehensive quality assurance process integrates precise measurements and rigorous testing at every stage of production, ensuring exceptional product reliability and performance.

Material Validation & Steel Hardness Testing

At GBM, quality assurance begins with comprehensive material testing. We validate all incoming materials against strict specifications to ensure they meet our high standards. Our steel hardness testing is performed using advanced Rockwell hardness testers, allowing us to verify the exact hardness of every steel component.

This critical first step ensures that only materials with the proper mechanical properties enter our production process. Our technicians measure multiple points on each sample, guaranteeing uniform hardness throughout the material. This meticulous approach prevents potential failures during machining and ensures the longevity of the final product.

3D Coordinate Measuring Machine (CMM) Inspection

Our state-of-the-art 3D Coordinate Measuring Machines provide precision measurement with accuracy down to 0.001mm. Every critical dimension is systematically verified against the engineering specifications during and after the machining process.

The CMM creates a digital map of the manufactured component and compares it to the original CAD design, generating comprehensive inspection reports. This allows us to detect even the slightest deviations and make necessary adjustments before components move to the next production phase. Our technicians are trained to interpret these results and implement corrective actions efficiently.

Functional Testing & Final Inspection

Before any product leaves our facility, it undergoes rigorous functional testing designed to simulate real-world conditions. Our water flow testing for fluid components ensures proper operation under various pressure conditions, while assembly verification confirms that all components integrate perfectly.

The final inspection includes visual examination for surface finish quality, comprehensive documentation review, and confirmation that all quality requirements have been met. Only after passing this multi-point final inspection process does a product receive approval for shipment. This systematic approach ensures that our customers receive only the highest quality components that will perform reliably in their applications.
