Shanghai, October 4, 2026 — Shanghai Size Test & Control Technology Co., Ltd. (STT) announced that a wheel hub helium leak testing system has completed factory commissioning and acceptance, and has been officially loaded for shipment to India. The equipment will be delivered to a well-known wheel hub manufacturing plant. This marks another significant delivery by STT following years of deep cultivation in the Indian market, underscoring the growing recognition of the company's helium mass spectrometry leak detection technology within overseas automotive component supply chains.

Helium Mass Spectrometry Technology Safeguards Wheel Hub Airtightness

The wheel hub helium leak testing equipment shipped on this occasion is based on the principle of helium mass spectrometry detection, utilizing helium as a tracer gas to perform high-precision airtightness testing on aluminum alloy wheel hubs. Through processes including vacuum evacuation, helium charging, and mass spectrometric analysis, the equipment can precisely identify microscopic leak points that may arise during the wheel hub casting process, achieving detection precision at an industry-leading level. As a core component for vehicle load-bearing and driving safety, the sealing performance of wheel hubs directly affects driving safety and product service life. Compared with traditional water immersion testing or pressure differential leak detection, the helium testing method offers advantages such as the elimination of human error, faster testing cycle times, and full automation capability, aligning with the Indian wheel hub factory's requirements for high quality and large-scale production.

Deepening Presence in the Indian Market: From "Customer Coverage" to "Batch Delivery"

Since its founding in 2008, STT has accumulated nearly two decades of technical expertise in the field of airtightness testing. The company has been recognized as a "National High-Tech Enterprise" and a "Specialized and Sophisticated Enterprise," and holds more than fifty patents cumulatively. STT's products have previously entered sixteen countries and regions, including India, the United States, South Korea, Singapore, Malaysia, Mexico, and Dubai, with the Indian market being one of its key overseas strategic regions.

India's automotive industry is currently in a phase of rapid expansion in alloy wheel hub production capacity. According to industry information, major Indian wheel hub manufacturers have continued to increase investment in aluminum alloy wheel hub capacity in recent years to meet the growing demand from the domestic passenger vehicle market and export orders. Alongside capacity expansion, there are heightened requirements for precision and automation levels in the airtightness testing process for finished wheel hubs. The equipment delivered by STT on this occasion was specifically customized to address the practical needs of Indian wheel hub factories in enhancing inspection efficiency and consistency during large-scale production.

The shipment of this wheel hub helium leak testing equipment to India represents not merely a single equipment export delivery, but rather signifies that STT's helium leak testing process standards and automated inspection capabilities are being incorporated into the quality control systems of an increasing number of overseas manufacturing enterprises. During the window of continued capacity expansion in India's wheel hub sector, high-precision and high-stability testing equipment will become a critical element for local factories in ensuring product yield rates and export competitiveness.
