Q&A: Is It Possible to Perform Leak Testing Without Custom Fixtures? A Comprehensive Guide to the Applications of Quick-Change Fixtures

This article outlines strategies for selecting between quick-change fixtures and custom jigs for airtightness testing. Quick-change fixtures are suitable for scenarios such as prototype testing, small-batch trial production, and production line spot checks, offering advantages such as low cost, short lead times, and flexible changeovers; custom tooling, on the other hand, is better suited for high-volume mass production and products with complex structures. Both should be used in combination at different stages of the product lifecycle to achieve cost reduction and efficiency gains.

How to Choose the Right Pressure for Leak Testing? From -95 kPa Vacuum to 5 MPa High Pressure: A Comprehensive Guide to Jingcheng Engineering Solutions

This article systematically analyzes the logic behind pressure selection for airtightness testing, covering four pressure ranges: low pressure (0–100 kPa), medium pressure (100–500 kPa), high pressure (>500 kPa), and ultra-high pressure (>1 MPa), covering core application scenarios such as consumer electronics, new energy vehicles, and hydrogen energy. It also introduces JCGK’s comprehensive pressure testing solutions and their key advantages.

Quick Q&A: What’s the Difference Between Differential Pressure and Flow-Type Leak Detectors? Everything You Need to Know in One Article—Don’t Make the Wrong Choice Again

This article systematically compares the key differences between differential pressure-type and flow-type airtightness testers. Differential pressure-type testers detect micro-leaks by comparing pressure changes between the test specimen and a standard reference chamber. They are resistant to temperature drift, offer high accuracy, and provide excellent repeatability, making them suitable for applications with high sealing requirements, such as new energy battery packs and automotive electronics; Flow-type testers directly measure the volume of gas leaked per unit time. They excel at identifying large leaks, measuring gas flow rates, and detecting blockages, making them suitable for flow performance analysis of valves, nozzles, and permeable membranes. The two types are not ranked as superior or inferior; rather, the choice depends on whether the testing objective is to determine "leakage" or "gas flow."
