Answering the "15th Five-Year Plan" Call | VMT's Self-Developed Vacuum Metallurgy Equipment Forges the Backbone of High-End Materials in Chinese Manufacturing

The Outline of the 15th Five-Year Plan for National Economic and Social Development has elevated the acceleration of high-level sci-tech self-reliance and self-improvement, and the cultivation of new quality productive forces, to an unprecedented strategic height. It identifies breakthroughs in core key technologies and the self-sufficiency and controllability of high-end materials as core pillars for building a modernized industrial system. In strategic sectors such as aerospace, new energy, and high-end equipment, truly high-end materials are beyond the reach of ordinary processes—their creation relies on vacuum metallurgy equipment that delivers ultimate purity and precise control. And this is precisely where Shanghai Vacuum Melting Technology Co., Ltd. excels with its hard-core strengths.

I. The Critical Importance of High-End Materials: The Bottleneck Is Not Only Technology, but Also Equipment

Nickel-based superalloys, titanium alloys, special steels, and other high-end metallic materials are the "skeleton and muscles" of a nation's major equipment. Their purity, density, and compositional uniformity directly determine equipment performance and safety. However, core equipment such as Vacuum Induction Melting furnaces (VIM) and Electroslag Remelting furnaces with protective atmosphere (ESR) have long been monopolized by a handful of Western companies. Domestic enterprises face not only high procurement costs and long delivery cycles, but also technological bottlenecks in core processes and control systems—leaving the mass production of high-end materials perpetually dependent on foreign suppliers.

Without self-controllable vacuum metallurgy equipment, there can be no truly high-end materials; without equipment autonomy, sci-tech self-reliance and self-improvement remain out of the question.

II. The "Core" of Weimai Technology: Breaking Foreign Monopoly Through Independent R&D

Shanghai Vacuum Melting Technology Co., Ltd. has long been deeply engaged in the field of vacuum metallurgy equipment. It has assembled an R&D team led by senior industry experts, focusing on core technologies such as vacuum melting, precision casting, and degassing refining. The company has achieved a leap from "following" to "keeping pace" and then to "leading in certain areas," with multiple equipment models reaching internationally advanced performance levels.

1. Core Equipment Matrix: Covering the Entire Process of High-End Material Manufacturing

Weimai Vacuum Melting Power Supply: Models ranging from 125 kW to 1000 kW have been successfully put into production. Incorporating the latest UDS+ technology and variable-frequency unidirectional stirring technology, it enables instant switching between forward and reverse stirring, delivering intense stirring during refining without temperature rise.

Vacuum Induction Melting Furnace (VIM): Through a vacuum environment combined with precise electromagnetic induction temperature control, it efficiently removes harmful impurities such as hydrogen, oxygen, and nitrogen, achieving micron-level precise regulation of alloy composition. It is the "heart" equipment for melting high-end materials such as nickel-based superalloys and titanium alloys.

Vacuum Arc Remelting Furnace (VAR): Performing arc remelting and purification under high vacuum, it significantly improves ingot density and purity. Specially designed for precision remelting of aerospace-grade titanium alloys and special steels, it is equipped with Weimai's self-developed fully automatic droplet control system, ensuring compositional stability and consistent quality.

Vacuum Precision Investment Casting Furnace (VPIC): In a vacuum environment, superalloy master alloys are induction-remelted and poured into ceramic molds to produce precision castings. Primarily used for manufacturing the most advanced superalloy castings, it is widely applied in aerospace, gas turbines, medical devices, power generation, and other fields.

Protective Atmosphere Electroslag Remelting Furnace (ESR): A metallurgical equipment that achieves metal remelting through heat generated by current flowing through high-resistance molten slag. It produces high-end alloy materials such as superalloys, tool and die steels, stainless steels, ultra-high-strength steels, and roll steels. Weimai Technology adopts a micro-positive pressure protective atmosphere detection system, completing electrode remelting in an inert gas environment to avoid metal oxidation and burning loss, and reducing the impact of gaseous elements on melting.

2. Technological Breakthroughs: From "Introduction and Absorption" to "Independent Innovation"

Weimai Technology rejects technological dependence and adheres to full-chain independent R&D:

It has conquered core algorithms such as droplet short-circuit control, constant melting rate swing, and intelligent dual closed-loop control, breaking foreign technological blockades in control systems.
It has developed key components such as high-efficiency vacuum systems, energy-saving water-cooling circuits, and coaxial conductive short networks. Compared with imported equivalent products, equipment energy consumption is reduced by 15%–20%, with stability and service life fully benchmarked against international first-tier brands.

III. The Strength of Chinese Manufacturing: Supporting the Future of High-End Materials Through Equipment Autonomy

Answering the "15th Five-Year Plan" call for sci-tech self-reliance and self-improvement, Weimai Technology takes domestic substitution of imports as its mission, providing "Chinese smart manufacturing" vacuum metallurgy equipment for domestic aerospace, rail transit, new energy, military, and other sectors:

Providing vacuum precision investment casting furnaces for the production of aero-engine blades and aerospace structural components, helping achieve breakthroughs in superalloy parts "from scratch, and from existing to superior."
Providing large-tonnage vacuum induction furnaces for new energy vehicles and energy storage sectors, supporting large-scale mass production of high-strength, lightweight alloy materials, and reducing industrial chain costs.
Providing customized vacuum metallurgy solutions for high-end equipment manufacturing enterprises, solving the "bottleneck" problem of material mass production, and promoting the implementation of new quality productive forces in the materials field.

Conclusion

Sci-tech self-reliance and self-improvement begin with core equipment; the rise of high-end materials is achieved through independent innovation. The blueprint of the "15th Five-Year Plan" has been drawn. Weimai Technology will always uphold its original aspiration of "building China's own vacuum metallurgy equipment," breaking monopolies through hard-core R&D, empowering materials with high-end equipment, and contributing to the leap from Chinese manufacturing to Chinese creation and Chinese smart manufacturing through solid efforts—adding Weimai's strength to the nation's high-level sci-tech self-reliance and the development of new quality productive forces!
