Quick Q&A: With so many domestic manufacturers of airtightness testers, why shouldn’t you base your selection solely on price?

This article focuses on selecting domestic air-tightness testers, covering topics ranging from price traps, testing methods, technical capabilities, brand reputation, and a five-step evaluation method for import substitution to a five-item supplier audit checklist. systematically addresses the six core procurement challenges faced by enterprises. Using JCGK as an example, it helps manufacturing companies select reliable suppliers that meet requirements for accuracy, production cycle times, and data traceability.

Q&A: Can Domestic Leak Testers Replace Imported Equipment? A Guide to Rational Evaluation

This article explains how domestic alternatives to industrial leak detection equipment are becoming a hot topic in manufacturing for reducing costs and improving efficiency, but the discussion often gets bogged down in two extremes: “catching up completely” or “not daring to take risks.” In fact, the answer depends on the specific scenario: the true value of substitution lies in eliminating hidden friction costs—such as spare parts cycles and technical support—and gaining comprehensive adaptation capabilities, including parameter switching, system integration, and customization, rather than simply replacing a single instrument.

Quick Q&A: What Is a Leak Tester Used For? A Must-Read Guide for Beginners—From Principles to Applications

This article describes how airtightness testers use four methods—positive pressure, negative pressure, differential pressure, and flow rate—to perform “controlled gas testing” on products, thereby detecting minute leaks that are invisible to the naked eye. When selecting a model, higher accuracy is not necessarily better; rather, the equipment should be matched to the product’s structure and permissible leak rate. Only through the use of custom fixtures and sample validation can a stable, traceable quality system be established.

A die-cast part with an intact exterior does not necessarily mean it is completely sealed internally

Quick Q&A: How can you quickly identify minor defects—such as porosity, sand holes, and cracks—in die-cast parts?

This article introduces the principles and methods of airtightness testing for die-cast parts. Differential-pressure leak detectors determine whether pores, sand holes, or cracks have formed through-leaks by comparing the pressure difference between a reference part and the part under test; they do not detect all internal defects. In practice, the custom tooling, the balancing phase, and the validation of reference parts are most often overlooked. A mature quality control plan should combine non-destructive testing, airtightness testing, and automated 100% inspection.
