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.

2026 Procurement Insider: How to Avoid the Low-Price Trap When Selecting Leak Testing Equipment

This article exposes the hidden cost pitfalls associated with low-cost, domestically produced airtightness testers, pointing out that while initial savings of a few thousand yuan in procurement costs may seem attractive, they can lead to subsequent losses of hundreds of thousands of yuan due to misjudgments, customer complaints, returns, and failed factory audits. Using JCGK as an example, the article highlights the core advantages of established suppliers in terms of software algorithm stability, customized delivery, after-sales response, and international certifications, urging manufacturing companies to focus on the total cost of ownership rather than simply the initial price.
