Die casting industry solutionsSolving industry problems of micro-leakage in die castings
In the field of automobile manufacturing, die castings are widely used in key parts such as engines, gearboxes, and body structures.Due to the characteristics of the die-casting process, defects such as shrinkage cavities and porosity that may exist inside the casting will form penetrating leakage channels, leading to fluid leakage, pressure loss and other problems, directly affecting the safety and reliability of the assembly system.
For the sealing testing needs of die-casting parts, Hairis provides a dual technical path solution based on a hydrogen-nitrogen mixture leak detector and a helium mass spectrometer leak detector to meet the testing needs of different precisions and budgets, ensuring that each die-casting part meets the design sealing requirements.
Dual paths meet differentiated needs
1. Hydrogen-nitrogen mixture leak detection plan
Using 5% hydrogen and nitrogen mixture as the tracer medium, it is highly safe and environmentally friendly
The detection accuracy can reach 10⁻⁶ mb·L/s level, meeting the detection requirements of most die castings.
Obvious advantages in equipment investment and operating costs, suitable for large-scale production line applications
Fast response speed, support online full inspection, single piece inspection time ≤15 seconds
2. Helium mass spectrometry leak detection solution
Using helium as the tracer gas, the detection accuracy is as high as 10⁻¹¹ mb·L/s
Suitable for inspection of special die castings with ultra-high precision requirements
Excellent repeatability and stability, meeting laboratory-grade standards
Support leak point positioning function to help process improvement
Intelligent detection process
Standardized testing process:
Workpiece preparation: Design special tooling fixtures to ensure rapid positioning and sealing of die castings
Gas filling: filling the inside of the die casting with tracer gas at a specific pressure
Accurate detection:
For hydrogen and nitrogen detection: use high-sensitivity hydrogen sensor for detection
For helium mass spectrometry detection: precise measurement with a mass spectrometer
Result judgment: automatically determines pass/fail, and displays the leakage rate in real time
Data management: Test data is automatically uploaded to the MES system and a quality report is generated.
Production line integration solution:
Support robot automatic loading and unloading to achieve fully automated inspection
Can be integrated into existing production lines to match production rhythm
Modular design for easy maintenance and upgrades
