Why does your leak test fail? You've invested in expensive production lines, but every shift brings a new batch of rejects. The root cause often lies in outdated or misapplied air tightness equipment. At Guangdong Hangao Technology Co., Ltd., we've seen it all—and we have the answers.
Imagine a medical device manufacturer facing a 12% failure rate on respiratory valves. Each leak costs $200 in scrap and delays patient care. Or an automotive supplier struggling with inconsistent EV battery pack sealing, risking thermal runaway. These aren't hypotheticals; they're daily realities.
The problem? Many leak test systems use differential pressure decay with poor temperature compensation, leading to false passes. Others rely on mass flow sensors that drift over time. The solution? Modern air tightness equipment that combines high-resolution pressure sensors (0.01% FS), adaptive algorithms, and real-time temperature correction.
Let's dive into three critical pain points and how our technology addresses them.
Pain Point 1: Inconsistent Test Results
Scenario: A Tier-1 automotive supplier tests transmission housings on three identical lines. Line A shows 98% yield, Line B 85%, Line C 92%. Why? Environmental factors—drafts, temperature gradients, operator technique—affect traditional pressure decay tests. Impact: 3% scrap rate increase, costing $500K annually. Solution: Our HG-3000 series uses a patented dual-chamber reference method that cancels environmental drift. Result: Repeatability within ±0.5% across all lines.
Pain Point 2: High Scrap Rates from Over-Testing
Scenario: An electronics manufacturer tests smartphone IP68 seals. To avoid field failures, they set tight limits, but 8% of good units are scrapped. Impact: $2M annual loss. Solution: Our adaptive leak test algorithm uses machine learning to differentiate between real leaks and seal deformation. By analyzing pressure decay curves, it reduces false failures by 60%.
Pain Point 3: Slow Cycle Times
Scenario: A medical device company tests insulin pen cartridges at 10 seconds each. Production target: 5 seconds. Impact: Bottleneck costing $300K in overtime. Solution: Guangdong Hangao Technology Co., Ltd. offers multi-channel simultaneous testing with fast-fill pneumatic circuits. Our HG-5000 system tests 4 cartridges in parallel, achieving 2-second cycle time per unit.

Applications & Partnerships
Our air tightness equipment is deployed in automotive (engine blocks, fuel systems, EV batteries), medical devices (syringes, catheters, implantables), electronics (smartphones, wearables), and packaging (blister packs, food containers). We partner with Bosch Rexroth for pneumatic components and National Instruments for data acquisition, ensuring industry-leading precision.
FAQ
1. Q: How does your equipment compensate for temperature changes? A: We use a reference chamber with identical thermal mass and a PID-controlled heater. The system measures delta temperature and applies a correction factor with ±0.1°C accuracy.
2. Q: What is the minimum detectable leak rate? A: Our HG-7000 can detect leaks as small as 1×10⁻⁶ mbar·L/s using mass flow sensors with 0.01 sccm resolution.
3. Q: Can I integrate with my existing MES? A: Yes, all models support OPC UA, Modbus TCP, and MQTT. We provide SDKs for Python and C#.
4. Q: What maintenance is required? A: Annual calibration of pressure sensors (traceable to NIST) and quarterly replacement of air filters. Our remote diagnostics predict failures.
5. Q: How do you handle high-volume production? A: Our HG-8000 multi-station system tests 32 parts simultaneously with a 3-second cycle. FIFO buffer ensures no bottleneck.
