In recent years, the field of vacuum melting furnaces has seen continuous technological advancements. For instance, Ningbo Graphene Innovation Center Co., Ltd. applied for a patent in August 2024 titled "A High-Temperature Melt Feeding Device for Vacuum Melting Furnaces" (Grant Publication No. CN 222688790 U); this device utilizes an inclined feed pipe and an anti-clogging mechanism to improve feeding efficiency and reduce the frequency of downtime for cleaning. Similarly, Shanghai Weimai Technology Co., Ltd. obtained a patent in November 2024 for a "Sealing Door for Vacuum Induction Melting Furnace Chambers" (Grant Publication No. CN 222165702 U); this design features a simple structure that lowers production costs while achieving-or even surpassing-the sealing performance of existing technologies.
As industry requirements for equipment performance and regulatory compliance rise, professional third-party testing services have emerged. Institutions such as the CAS Guangxi Chemical Technology Research Institute offer comprehensive testing services for vacuum melting furnaces, covering areas such as structural integrity, thermal performance, safety protection, and environmental impact, all aimed at helping enterprises optimize operations and enhance compliance
Regarding domestic market applications, Guangtai Vacuum Technology Co., Ltd.-a leading player in the rare-earth vacuum equipment sector-holds a significant market share in the domestic rare-earth permanent magnet material industry with its vacuum melting and sintering furnaces. The company plans to boost production capacity for these furnaces through expansion projects and is establishing an R&D center to develop cutting-edge equipment technologies. Meanwhile, downstream enterprises such as Danyang Kaixin Alloy Materials Co., Ltd. put a domestically produced 3.5-ton large-capacity vacuum induction melting furnace into operation in 2025; this equipment employs advanced technology designed to enhance alloy purity, quality, production capacity, and eco-friendly manufacturing standards.
