Sichuan Aviation Industry Chuanxi Machinery, a subsidiary of state aircraft conglomerate AVIC, says its hot isostatic press, the world's largest by hot-zone size, has passed its pressure test. Such presses use heat and high-pressure gas to squeeze internal voids out of metal parts. The hot zone, the heated chamber, caps how large a casting they can treat in one piece. This one measures 2,400 mm (about 7.9 feet) across and 3,500 mm (about 11.5 feet) tall. Presses of this kind densify large titanium and superalloy castings and 3D-printed parts. Sichuan province's special equipment inspection institute monitored the test in Anshun, Guizhou province, where the unit reached 205 MPa, roughly 2,000 times atmospheric pressure.

360 Group's AI vulnerability hunter Tulongfeng is the first product in China to pass a new evaluation by the China Academy of Information and Communications Technology (CAICT), an industry ministry research institute. Such tools can audit code at a scale human teams cannot, and CAICT's first published results give Chinese buyers an official yardstick for judging them. Tulongfeng met all 12 of CAICT's requirements, which cover the range of software examined, task complexity, automation and accuracy. 360 says the system has found more than 15,000 vulnerabilities, including long-hidden Windows and Office flaws that Microsoft credited. More than 500 companies, including operating system makers Kylin Software and UnionTech, use it for security testing.
