May 28, 2026 – The 2026 Chongqing International Industrial Expo and the 26th LiJia International Intelligent Equipment Exhibition grandly opened at the Chongqing International Expo Center. Under the theme “Intelligence Drives New Quality, Craftsmanship Gathers Innovation,” the exhibition covered a total area of 90,000 square meters, bringing together 1,300 well‑known leading enterprises from home and abroad. The event showcased 1,100 sets of high‑end equipment weighing over 1 ton each, as well as tens of thousands of precision core functional components. Exhibits comprehensively covered metal‑cutting machine tools, industrial automation, laser sheet metal, new energy vehicle complete equipment, industrial robots, high‑precision quality inspection, and many other fields.

As a technology‑driven enterprise focused on the R&D and application of seal leak detection technology, AMT Leak Testing Technology (Chongqing) Co., Ltd. (hereinafter referred to as “AMT”) made a splendid appearance at the exhibition with its full range of AMT series air tightness testers and complete seal leak detection solutions, attracting considerable attention from professional visitors and industry customers.

Nearly Two Decades of Deep Focus on Leak Detection – AMT Series Products Widely Acclaimed

AMT Leak Testing Technology (Chongqing) Co., Ltd. is a technology‑driven enterprise dedicated to the R&D and application of seal leak detection technology, headquartered in Shapingba District, Chongqing. The company’s technical heritage dates back to 2005, meaning it has been deeply engaged in the field of seal leak detection for nearly 20 years.

At this exhibition, AMT highlighted its AMT series direct pressure/differential pressure air tightness testers, multi‑channel synchronous testing systems, and customized seal testing solutions for industries such as automotive components, new energy batteries, consumer electronics, and gas appliances.

AMT‑700D Differential Pressure Air Tightness Tester – As the core product on display, it is a high‑precision professional‑grade seal leak detection instrument featuring a full‑touchscreen design. Based on the differential pressure method – one of the most popular and highest‑precision sealing test techniques – it can detect extremely small leaks, with a differential pressure sensor resolution reaching 0.01 Pa. AMT series products also support multiple test methods, including positive and negative pressure, flexibly meeting high‑precision test requirements across various industries and scenarios.

AMT‑400 Four‑Channel Direct Pressure Air Tightness Tester – Another star product that attracted great attention. Integrating four independent test stations with high precision and high efficiency, it can perform leak detection on four products or multiple test points simultaneously, greatly improving production line test efficiency. One tester, combined with a switching device, can cover multiple test stations, significantly reducing equipment procurement costs – a solution that drew strong interest from many manufacturing enterprises on site.

In addition, AMT also demonstrated a series of supporting solutions, including multi‑channel synchronous testing systems, non‑standard custom sealing test tooling, and intelligent data management software. Users can flexibly configure test programs according to different product leak rate requirements. The system supports storage of up to 100 test programs and recording of millions of test results, with USB automatic export to Excel format. It can also connect to MES systems for real‑time traceability of test data, providing strong support for users to achieve digital quality management.

High Booth Popularity, Lively On‑Site Exchanges

On the first day of the exhibition, AMT’s booth attracted many professional visitors. Specialists from industries such as automotive components, new energy batteries, consumer electronics, security electronics, and gas appliances came to learn about product performance and technical features, and many enterprise representatives expressed intentions for cooperation on site.

AMT also showcased the lightweight AMT‑300 Portable Direct Pressure Air Tightness Tester for after‑sales maintenance and on‑site testing scenarios. With a mobile integrated box structure, built‑in air pump and PLC controller, it can complete on‑site leak testing independently without an external air source – making it highly suitable for automotive 4S shops, repair shops, refrigeration equipment maintenance sites, and other mobile testing scenarios, becoming a highlight in the after‑sales maintenance field.

Exhibition Continues to Boost Chongqing’s High‑End Equipment Manufacturing Cluster

This year’s LiJia Exhibition was not only a grand showcase of high‑end equipment but also a platform for deep industry‑university‑research integration. More than 60 high‑end industry summits, technical forums, and matchmaking events were held concurrently, bringing together technical experts and industry leaders from aerospace, new energy vehicles, precision components, and other high‑tech application fields. The “2026 Chongqing First (Set) Major Technical Equipment New Product Launch Conference,” hosted by the Chongqing Municipal Commission of Economy and Information Technology, was also held during the exhibition, highlighting Chongqing’s latest breakthroughs in high‑end equipment R&D and industrial upgrading.

As a manufacturing hub, Chongqing has a strong industrial foundation in automobiles, motorcycles, aerospace, and more. Against the backdrop of current manufacturing transformation and upgrading, precision testing instruments are playing an increasingly important role as a key link between “manufacturing” and “intelligent manufacturing.” As a high‑tech enterprise that has grown up locally in Chongqing, AMT’s independently developed air tightness testing solutions not only provide timely and professional localized services to manufacturing enterprises in Southwest China, but also strongly support the quality safety and industrial upgrading of high‑end equipment.

Professional Excellence for Quality, Innovation for the Future

Looking ahead, AMT will continue to uphold its mission of “making leak detection easier” and adhere to its service philosophy of “leading technology, continuous improvement; rapid response, mission accomplished.” The company will keep deepening its expertise in seal leak detection technology, committed to providing more reliable, accurate, and efficient seal testing equipment and automation solutions to industrial enterprises worldwide.
