Shanghai Vacuum Melting Technology Co., Ltd. Celebrates Its Second Anniversary!

Two years ago today, a group of dreamers with years of experience in the special metallurgical equipment field founded Shanghai Vacuum Melting Technology Co., Ltd. on the innovative soil of Shanghai. We deeply understand that high-end special alloys are the "industrial food" for national strategic industries such as aerospace, national defense and military industry, and new energy, while vacuum metallurgical equipment is the "pillar of the nation" for producing these critical materials. For a long time, China’s high-end special metallurgical equipment has been heavily dependent on imports, with core technologies controlled by others.

Driven by the original aspiration to "break foreign monopoly and achieve domestic substitution," VMT has embedded technological innovation into its DNA since its inception. Focusing on core technology areas such as vacuum induction melting, vacuum precision casting, and protective atmosphere electroslag remelting, we have tackled one technical challenge after another, working day and night. In just two years, we have obtained 19 patents and 22 software copyrights, successfully achieving technological breakthroughs in key equipment such as high-temperature single-crystal furnaces, contributing VMT’s strength to the upgrading of China’s special metallurgical equipment industry.

Two years may be but a blink in the long river of history, but for VMT, it has been a journey full of struggle and harvest.

• In June 2024, just two months after its establishment, the company completed its angel round of financing led by Gaoxin Capital, gaining high recognition from the capital market.

• In August 2024, Suzhou Vacuum Melting Technology Co., Ltd. was established, marking the first step in its nationwide layout.

• In 2025, the company won three major honors: National High-Tech Enterprise, National Technology-Based SME, and Provincial Innovative SME.

• In December 2025, the company successively won bids for major equipment procurement projects from China Fifteenth Metallurgical Construction Innovation Research Institute and Central South University’s Advanced Materials Powder Metallurgy Research Institute.

• As of May 2026, the company has participated in dozens of bidding projects, with orders for various furnace types totaling nearly 30 units. Customers include state-owned special steel enterprises, military enterprises, private and listed special steel companies, etc.

Behind these achievements is the hard work of every VMT employee. From repeated experiments in the R&D laboratory to meticulous work in the production workshop; from on-site installation and commissioning to timely after-sales service responses, we have won customer trust with professionalism and focus, and set an industry benchmark with quality and reputation.

Vacuum Induction Melting Furnace (VIM) is a complete set of smelting equipment that melts metals under vacuum using medium-frequency induction heating. It is a complete vacuum metallurgical system for producing superalloys, ultra-high-strength stainless steels, corrosion-resistant alloys, aviation bearing steels, and other high-value special alloys. It consists of a melting chamber, vacuum system, power supply system, etc., with capacities ranging from 0.5 to 30 tonnes. Different capacities correspond to single-chamber batch furnaces and multi-chamber semi-continuous furnaces. It can be classified by melted material into master alloy and wrought alloy melting furnaces, and by furnace type into batch and semi-continuous furnaces.

Vacuum Precision Investment Casting Furnace (VPIC) re-melts superalloy master alloy under vacuum and pours it into ceramic molds to produce precision castings. It is mainly used to produce the most advanced superalloy castings, widely applied in aerospace, gas turbines, medical devices, power generation, and other fields. VMT’s equipment is of the semi-continuous type, available in vertical top-loading and horizontal side-loading three-chamber structures, consisting of a melting chamber, ingot chamber, and loading chamber separated by isolation valves, housing melting components, molds, and completing material loading respectively.

Vacuum Arc Remelting Furnace (VAR) uses a DC arc as a heat source under vacuum conditions for metal melting. It can melt nickel-based, iron-based, and cobalt-based superalloys, reactive and refractory metals such as titanium and zirconium, as well as special steels. It is composed of furnace body, power supply and control system, vacuum and inert gas system, cooling water system, weighing system, X-Y adjustment system, camera system, compressed air and other auxiliary systems, fully automatic melting control system, and safety alarm system.

Protective Atmosphere Electroslag Remelting Furnace (ESR) generates heat by passing current through a high-resistance slag to remelt metals. It produces high-end alloy materials such as superalloys, tool and die steels, stainless steels, ultra-high-strength steels, and roll steels. It mainly consists of furnace body, power supply and conductive system, electrical control system, cooling water system, etc. Melting and solidification are typically carried out under an argon protective atmosphere, and vacuum units can also be equipped for vacuum melting as required. Shanghai Vacuum Melting Technology adopts a micro-positive pressure protective atmosphere detection system to complete electrode remelting in an inert gas environment, avoiding metal oxidation and burn-off, and reducing the impact of gas elements on melting.

Vacuum Induction Melting Degassing Furnace (VCAP) is developed for special applications in the ferrous and non-ferrous metal industries. It inductively melts solid metal under atmospheric conditions. During the refining stage, the molten metal is stirred and degassed under vacuum, or decarburized and refined by top/bottom blowing O₂/Ar, followed by rapid casting under atmospheric or inert gas protection.

Looking ahead, Shanghai Vacuum Melting Technology will continue to shoulder the mission of "Forging the pillar of the nation, empowering high-end manufacturing," and will deeply cultivate and forge ahead in the field of special metallurgical equipment. We believe that with the joint efforts of all VMT employees and the strong support of our partners, Shanghai Vacuum Melting Technology will surely create an even brighter tomorrow and make greater contributions to the high-quality development of China's manufacturing industry.
