Application of JCGK’s Four-Channel Leak Tester in Automated Production Facilities

Quick Q&A: If Your Leak Tester Isn’t Working Well, Should You Switch Brands? Try These 5 Steps First

2026-11-07

This article addresses the question of whether to “repair, upgrade, or replace” airtightness testing equipment when it malfunctions, providing a selection guide through six Q&A sections: First, investigate potential issues with fixtures and parameters. Then, evaluate equipment based on five criteria: accuracy and repeatability, testing principles, fixture customization, automation integration, and after-sales service. Verify performance through four practical tests—repeatability, standard leak holes, actual products, and production cycle time—and recommend pilot testing before full-scale implementation to avoid losses resulting from blindly switching brands.

Quick Q&A: How Should Suppliers of Leak Tightness Testing Equipment Be Evaluated in High-End Manufacturing Bidding and Selection Processes?

2026-10-31

This article explains the logic behind selecting airtightness testers in a “Six Questions, Six Answers” format: High-end manufacturing companies should shift from a price-driven approach to a comprehensive evaluation of suppliers’ technical capabilities, custom tooling, and automation capabilities; specification sheets cannot replace actual testing and verification, and tooling, data traceability, and instruments are equally important; The procurement process must proceed in three phases—technical pre-qualification, sample validation, and production line acceptance—with actual testing and acceptance serving as the key factor in decision-making.

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

2026-10-26

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

2026-10-17

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

2026-10-10

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?

2026-09-30

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.

Q&A: How to Efficiently Inspect Breathable Films of Various Specifications? Jingcheng Engineering’s Single Machine Supports Multiple Product Models

2026-09-21

This article introduces the Jingcheng Engineering JC-WG200 Comprehensive Tester for Waterproof and Breathable Membranes: Addressing the challenge of having to verify the two independent properties—air permeability and water pressure resistance—of ePTFE products separately, this solution uses “one device + multiple test fixtures + independent parameters” to enable testing of multiple products with a single machine, saving both costs and space. It also supports upgrades to automated production lines, providing an efficient and reliable testing solution for R&D, quality control, and procurement.
