Breaking Import Dependence: Self-Developed Vacuum Melting Power Supplies by Shanghai Vacuum Melting Technology Empower Vacuum Melting with Chinese Core StrengthIn the field of vacuum melting for high-end special alloys and precision castings, core power supply systems have long been dominated by imported brands. With their technological first-mover advantages, international brands once became the default choice for industrial users. However, high procurement costs, long delivery cycles, inadequate localized services, and restricted supply of key spare parts have long been pain points for domestic enterprises. Today, Shanghai Vacuum Melting Technology Co., Ltd. has broken this deadlock through independent research and development. Our vacuum induction furnace melting power supply series and electromagnetic stirring power supply series are technologically on par with and even surpass international products in performance, providing customers with a more stable, efficient, and reliable Chinese solution as core power equipment. Self-Developed Vacuum Melting Power Supplies: Matching Imports in Performance, Surpassing Them in Advantages.
Wide power range to meet full-scenario melting demandsModels from 125kW to 1000kW are successfully in production, suitable for full-specification vacuum induction furnaces from laboratory trials to industrial mass production. Whether for small and medium-tonnage precision alloy melting or large-tonnage superalloy mass production, we provide matching power solutions without compromising process requirements. Digital intelligent control for exceptional operational stabilityAdopting a DSP+FPGA dual-core digital control architecture combined with a series resonant circuit topology, our power supplies enable load-adaptive regulation. Even with changes in furnace charge conditions and load fluctuations during melting, the system responds in real time and outputs stably, eliminating melting interruptions and temperature instability caused by unstable working conditions in traditional power supplies. Meanwhile, the power factor reaches ≥0.95, greatly reducing reactive power loss, cutting electricity expenses, avoiding power grid penalties for low power factor, and significantly lowering long-term operating costs.
High efficiency and energy saving for higher-quality meltingOur power supplies maintain high efficiency across the entire power range. Compared with imported equipment of the same power rating, unit melting energy consumption is reduced by 5%–8%. For continuously operating industrial furnaces, this results in considerable annual electricity savings, reduces internal heat loss, and extends the service life of key components. Electromagnetic Stirring Power Supplies: Full-spectrum solutions to solve the final quality challenge in meltingMany users focus only on the heating capacity of melting power supplies while ignoring the decisive impact of stirring power supplies on casting quality. We offer two professional stirring solutions to meet diverse process needs:
Both stirring power supplies adopt domestic core control technology, with fast response and high control precision, fully solving the pain points of imported stirring power supplies, such as scarce spare parts and slow service response. Beyond replacement: striving to surpass international benchmarks
