Testing Technologies and Methods

Test Components

Includes air source treatment unit, pressure regulation module, and precision sensors, forming a complete closed-loop detection system.

Internal Pressure Test Method

By injecting a specific pressure gas inside the tested workpiece, the pressure variation is detected to assess sealing performance, suitable for enclosed cavity testing.

Direct Pressure (Pressure Drop) Test Method

Directly applies test pressure and monitors pressure decay, suitable for production scenarios with high testing speed requirements.

Core Advantages

High-Precision Detection

Uses imported high-precision pressure sensors (accuracy ±0.1% F.S) and 24-bit AD acquisition chips; detection sensitivity can reach 0.1Pa, ensuring accurate and reliable test results.

High Testing Speed

Optimized inflation and testing process design combined with a fast-response sensing system; the testing cycle for a single product can be shortened to under 1 second, improving production efficiency.

Flexible Testing Modes

Supports both positive and negative pressure testing modes; built-in multiple test programs; customizable test parameters based on different product characteristics to meet diverse needs.
