The world's largest hot isostatic pressing (HIP) unit, in terms of hot zone size, which was independently developed by Sichuan Aeronautical Industry Chuanxi Machine Co., Ltd., has successfully completed its pressure testing in Anshun, Guizhou. This unit boasts a hot zone diameter of 2,400 millimeters and a height of 3,500 millimeters, achieving a test pressure of up to 205 megapascals. During the entire testing process, the data collected was comprehensive, and the performance indicators remained stable.

Hot isostatic pressing equipment is a vital component for upgrading high-end manufacturing industries, finding applications across a broad spectrum. Faced with the absence of mature experience to guide this test, the project team committed to independent innovation and surmounted numerous technical hurdles. The successful completion of the pressure test has laid a robust foundation for the subsequent commissioning, delivery, and engineering applications of the equipment. Chuanxi Machine will persist in advancing related endeavors, contributing to the development of China's industrial mother machines and the high-end equipment manufacturing sector.
