Quality Control
Toolcraft prioritizes the integrity of the Axle Assembly with a dedicated focus on Leak Test Cap performance.
- Cap Functionality: Each Leak Test Cap undergoes a rigorous inspection process to guarantee proper sealing and leak detection capabilities. This ensures the Axle Assembly is thoroughly tested for leaks during the Functional Testing stage (mentioned previously).
Here’s how we achieve this:
- Dimensional Verification: High-precision measuring equipment confirms all critical dimensions of the Leak Test Cap meet exact specifications, guaranteeing a secure fit with the Axle Assembly.
- Material Validation: Material properties are rigorously tested to ensure the Leak Test Cap is constructed from durable, leak-proof materials that can withstand demanding conditions.
By implementing these dedicated Leak Test Cap quality control measures, Toolcraft delivers a reliable solution for ensuring the integrity of every Axle Assembly.
Quality Control
Toolcraft’s comprehensive quality control procedures ensured the Brass Die scraper met stringent performance and reliability standards:
- Dimensional Inspection: Coordinate Measuring Machines (CMM) were used to verify all critical dimensions and tolerances.
- Material Testing: Metallurgical tests were conducted to confirm the material’s properties and compliance with specifications.
- Non-Destructive Testing (NDT): Techniques such as ultrasonic testing and magnetic particle inspection were employed to detect any internal or surface defects.
- Functional Testing: The assembled Brass Die scraper underwent rigorous functional tests to ensure proper operation and integration with Michelin’s manufacturing process.
- Final Inspection: A thorough final inspection was performed to validate the overall quality and readiness of the Brass Die Scraper before delivery to Michelin.
