Top 10 Medium Frequency Furnace Suppliers in China | 2025 Rankings and Comments

With over five decades in the industry, Metallurgical Masters Co., Ltd. is a name that needs no introduction. Based in Shanghai, this veteran supplier has built its reputation on delivering rugged, long-lasting medium frequency electricity furnace equipment that can handle the toughest recycling jobs. What sets them apart? Their ability to integrate their furnaces with complementary systems, like lead acid battery recycling equipment, creating seamless workflows for clients processing scrap batteries into reusable lead.

Metallurgical Masters' furnaces are known for their stability—even when melting mixed metals—and their after-sales service is legendary. Clients often praise their 24/7 technical support, which minimizes downtime. "We've had their 5-ton furnace running for 12 years with only minor repairs," says a scrapyard owner in Germany. "It's the backbone of our operation."

EcoSmelt Technologies is all about green innovation. This Beijing-based supplier has made waves with its medium frequency furnaces that cut energy use by up to 30% compared to traditional models—no small feat in an industry where electricity bills can eat into profits. Their secret? A patented coil design that reduces heat loss and improves melting efficiency.

But EcoSmelt doesn't stop at furnaces. They're also a go-to for air pollution control system equipment, offering scrubbers and filters that ensure compliance with strict emission standards in Europe and North America. "We wanted to expand into Germany, but their laws are tough," explains a recycling plant manager in Jiangsu. "EcoSmelt's furnace plus their air pollution control system let us hit all the targets without sacrificing output."

Not every recycler needs a massive industrial furnace, and RecyclingPro Machinery gets that. This Guangzhou-based supplier specializes in medium frequency furnaces tailored for small to medium enterprises (SMEs), with capacities ranging from 500kg to 2 tons per hour. Their modular designs mean businesses can start small and upgrade as they grow—no need to overinvest upfront.

What's particularly impressive is their foray into li battery recycling equipment, pairing furnaces with lithium-ion battery breaking and separating systems for a one-stop solution. "We started with just a furnace for scrap copper," says a startup recycler in Zhejiang. "A year later, we added their li battery setup, and now we're processing both metals and batteries. The transition was smooth because the systems are designed to work together."

When it comes to heavy lifting, FoundryWorks China is the supplier of choice for many industrial giants. Their medium frequency furnaces are built for brute force, with some models capable of melting 10 tons of metal per hour—ideal for large-scale foundries and scrap yards processing thousands of tons monthly. What's more, they offer custom solutions, tweaking furnace size, power, and controls to fit unique client needs.

Their metal melting furnace equipment is also known for durability; the company claims a 15-year lifespan for their core components, thanks to high-grade refractory materials. "We process old ship parts and construction scrap—tough, dirty work," says a plant manager in Shandong. "FoundryWorks' furnace has been churning through it all for eight years, and we've only replaced minor parts. It's a tank."

For recyclers operating in regions with strict environmental laws, GreenTech Furnaces is a lifesaver. This Hangzhou-based supplier doesn't just sell furnaces—they sell peace of mind. Every medium frequency furnace comes with optional air pollution control machines equipment, including bag filters, electrostatic precipitators, and odor neutralizers, ensuring emissions stay well below legal limits.

They also offer free compliance audits, helping clients navigate complex regulations in markets like the EU and California. "We were hit with fines before switching to GreenTech," admits a recycler in Guangdong. "Now, their team checks our emissions monthly, and we haven't had a single issue. It's worth every penny for the stress relief."

SmartMelt Solutions is where traditional furnace manufacturing meets cutting-edge tech. Their medium frequency furnaces are equipped with AI-driven controls that optimize melting times, adjust power usage in real time, and even predict maintenance needs via IoT sensors. For example, if a coil is overheating, the system alerts operators and automatically reduces power to prevent damage.

They've also expanded into circuit board recycling equipment, integrating furnaces with dry separation systems to recover precious metals like gold and silver from e-waste. "The AI takes the guesswork out," says a tech-savvy recycler in Shenzhen. "I can monitor the furnace from my phone, and it sends me alerts before something breaks. It's like having a 24/7 technician on staff."

Not all recycling happens in fixed plants—some operations need to move where the scrap is. GlobalRecycler Equipment specializes in portable medium frequency furnaces, compact units mounted on trailers or skids that can be transported to construction sites, demolition zones, or remote mining areas. Their PHBM series of portable briquetting machines (like the PHBM-002 and PHBM-003) are also popular, compressing metal powder into briquettes for easier transport to the furnace.

"We work with logging companies that generate a lot of scrap metal from old machinery," explains a client in Yunnan. "GlobalRecycler's portable furnace lets us melt it on-site, turning waste into sellable ingots without hauling heavy scrap long distances. It's saved us thousands in transportation costs."

When purity matters most—say, for recycling medical equipment or high-grade copper wiring—PrecisionMetals Machinery delivers. Their medium frequency furnaces are engineered to minimize contamination, with features like inert gas purging and precision temperature control that ensure metals are melted at exactly the right heat to separate impurities.

They also offer cable recycling equipment, including scrap cable strippers and granulators, that work in tandem with furnaces to recover clean copper and aluminum. "We supply aerospace manufacturers, who demand 99.99% pure aluminum," says a recycler in Tianjin. "PrecisionMetals' furnace gets us there every time. The cable stripper ensures we're feeding it clean scrap, so the final product meets the strictest specs."

Building a new recycling plant from scratch can be overwhelming—there are furnaces, separators, conveyors, and systems to coordinate. AllInOne Recycling Systems simplifies this with turnkey solutions: they design, install, and commission entire recycling lines, including medium frequency furnaces, auxiliary equipment, and even training for staff. Their "one contract, one point of contact" approach has made them popular with first-time plant owners.

"We had no idea where to start when we decided to open a lead acid battery recycling plant," recalls an entrepreneur in Hubei. "AllInOne handled everything—from the furnace to the effluent treatment machine. Six months later, we were up and running, and they still check in monthly to make sure everything's smooth."

NanoMet Furnaces is pushing the boundaries of materials science with their innovative use of nano ceramic balls in furnace linings. These tiny, ultra-durable balls reduce wear and tear, extending lining life by up to 50% compared to traditional materials. Their medium frequency furnaces also feature microcrystalline ceramic components that improve heat retention, further boosting efficiency.

While they're a newer player, their focus on R&D has earned them a loyal following among high-tech recyclers. "We were skeptical about the nano ceramic claims at first," admits a materials engineer in Shanghai. "But after two years, our furnace lining still looks brand new. We've saved so much on replacement costs that the upgrade paid for itself."
