| Our systems utilize advanced air pressure leak tester technology. Depending on your product’s specific requirements, We offer two primary testing methodologies: | Working Principle: | |
| Ideal for a wide range of products. The air leak tester inflates the test part (or a customized mold cavity) to a specific pressure. It then cuts off the air source and monitors the pressure drop over time. | 1. Direct Pressure Decay Method (Gauge Pressure) | |
| Simple Operation: Easy to set up and understand. Cost-Effective: Uses standard air, zero consumable costs. | ||
| Versatile: Works for products with inflation ports (direct filling) or sealed products without ports (using a volumetric sealed chamber/mold). | ||
| Designed for high-precision requirements. The machine simultaneously inflates the test product and a “Standard Reference Part” (a known good product). It measures the pressure difference between the two. | 2. Differential Pressure Method (Comparison) | |
| Higher Accuracy: Eliminates environmental interference (temperature, deformation)｜High Sensitivity: Detects micro-leaks effectively using a 24-bit high-precision pressure converter. | ||
At the heart of our system lies an advanced 24-bit AD converter, Distinguishing our equipment from standard market options. As a leading air leak tester manufacturer, Wewon prioritize measurement accuracy. Whether you are testing medical catheters or automotive die-castings, Our air pressure leak tester detects pressure drops as slight as 0.1 Pa. This high sensitivity ensures that even the most microscopic defects are identified, Guaranteeing that only 100% sealed products leave your production line.
To meet the high-speed demands of modern manufacturing, Wewon offer flexible configurations ranging from single-station to multi-channel systems. Our multi-channel air leak test machine allows for the simultaneous testing of 2 to 4 products, significantly reducing cycle times. Unlike trading companies, We are a direct air leak tester factory. This means we can customize the channel logic and testing sequence to perfectly match your existing automation line, Maximizing your daily output without compromising accuracy !
