Alpha Technology (Alpha Technology Service Co., Ltd.), established in 2017 and headquartered in Dachang Hui Autonomous County, Hebei Province, is a national-level specialized “Little Giant” enterprise and a key member of the China Integrated Circuit Innovation Alliance. We are one of China’s leading manufacturers of high-precision edge welded bellows and critical vacuum components, serving the global semiconductor, aerospace, medical, and energy industries.
World-Class Manufacturing Infrastructure
Our facility spans 60,000 square meters with 50,000m² of built-up area, including a 6,000m² Class 10,000 cleanroom dedicated to ultra-clean bellows assembly. This advanced infrastructure — combined with in-house micro-plasma welding, CNC machining, helium mass spectrometer leak detection, and metallurgical testing — enables us to deliver components that meet the most demanding vacuum integrity and reliability standards.
We maintain a comprehensive catalog of over 248 standard bellows models (AT-Series) spanning ODs from 10mm to 1,200mm, with custom configurations available for specialized applications. Explore the complete dimensional database on our Welded Bellows Specs page.
