2025 Ranking of Leading Furnace Factories in China

1. Evergreen Industrial Furnaces: Redefining Metal Melting Efficiency

Tucked away in the industrial hub of Wuxi, Evergreen Industrial Furnaces has quietly become a global name in metal melting— and for good reason. Walk through their facility, and you'll notice something different: the hum of machinery is softer, the air cooler, and the workers speak proudly of "melting more with less." That's the Evergreen promise, and it's backed by their star products: metal melting furnace equipment and medium frequency electricity furnace equipment designed to slash energy use by up to 30% compared to traditional models.

"We started 15 years ago with a simple question," says Zhang Wei, Evergreen's founder and chief engineer. "Why can't melting metal be both powerful and planet-friendly?" Today, that question drives their R&D lab, where a team of 50 engineers tinkers with magnetic induction technology and heat-recovery systems. The result? Their latest medium frequency furnace, the EF-2000, melts 2 tons of steel per hour while using 25% less electricity than competitors. For a small auto parts manufacturer in Changchun, that translated to saving ¥120,000 annually on energy bills—funds they reinvested in hiring 10 new workers.

What truly sets Evergreen apart is their focus on accessibility. They don't just sell furnaces; they partner with clients to optimize workflows. Take their work with a rural foundry in Sichuan, which struggled with inconsistent power supply. Evergreen's engineers retrofitted a standard furnace with a battery backup system, ensuring steady melting even during blackouts. "Now we can meet deadlines without worrying about the grid," says Li Mei, the foundry's operations manager. "Evergreen didn't just give us a machine—they gave us reliability."

2. EcoCycle Tech Solutions: Powering the Battery Recycling Revolution

In Guangzhou, EcoCycle Tech Solutions is on a mission: to turn the tide on battery waste. With over 200 million lead-acid batteries and 100 million lithium-ion batteries reaching end-of-life in China annually, the need for safe, efficient recycling has never been greater. EcoCycle's answer? A suite of lead acid battery recycling equipment and li battery recycling equipment that transforms hazardous waste into reusable materials—all while keeping workers and communities safe.

Step into their demo facility, and you'll see the process in action. A lead-acid battery is fed into a shredder, where it's broken down into plastic, lead plates, and acid. The acid is neutralized and repurposed as fertilizer; the lead is melted in a low-emission furnace (yes, they make those too) and cast into new battery grids. For lithium-ion batteries, their automated separation line uses air classification and electrostatic sorting to recover cobalt, nickel, and lithium—critical materials for new EV batteries.

"Our clients aren't just recyclers—they're pioneers," says Wang Jun, EcoCycle's sales director. "Take GreenCycle Recycling in Shenzhen. They bought our lithium battery line in 2023, and now they process 500 tons of batteries monthly, recovering 95% of valuable metals. That's 500 tons that would've ended up in landfills, poisoning soil and water." For GreenCycle, the investment paid off in 18 months, thanks to high material recovery rates and government subsidies for green tech.

EcoCycle's secret? They don't stop at equipment. They train clients' teams on safety protocols, help navigate environmental regulations, and even assist with marketing their recycled materials to manufacturers. "Recycling is a team sport," Wang adds. "We win when our clients win."

3. CleanAir Systems Group: Breathing Easier with Smart Emission Control

In the industrial city of Tianjin, where factories once choked the sky with smoke, CleanAir Systems Group is writing a new story—one where manufacturing and clean air coexist. Their claim to fame? Air pollution control system equipment that doesn't just meet China's strict standards but exceeds them, turning emissions into a non-issue for clients.

"We believe 'clean' shouldn't be a luxury," says Chen Hua, CleanAir's environmental scientist. "Every factory, big or small, deserves to operate without harming the planet." That belief led to their flagship product: the CAS-5000, an air pollution control system that uses multi-stage filtration (electrostatic precipitators, activated carbon beds, and UV light) to remove 99.7% of particulates and toxic gases. For a copper smelter in Anhui, installing the CAS-5000 meant cutting sulfur dioxide emissions from 500 mg/m³ to just 15 mg/m³—well below the national limit of 30 mg/m³.

What's remarkable about CleanAir is their hands-on approach. When a furniture manufacturer in Hangzhou struggled with volatile organic compounds (VOCs) from paint drying, CleanAir didn't just sell them a filter. They sent a team to audit the entire production line, redesigned the drying process to reduce VOCs at the source, and then installed a tailored control system. "Now, our workers don't cough during shifts, and neighbors no longer complain about the smell," says the manufacturer's owner, Lin Tao. "CleanAir didn't just fix our emissions—they made our factory a better place to work."

4. SmartFoundry Innovations: Empowering Small Businesses with Smart Furnaces

Not all industrial powerhouses are big—some are just smart. SmartFoundry Innovations, based in Ningbo, specializes in making advanced furnaces accessible to small and medium enterprises (SMEs) that can't afford giant, industrial-scale equipment. Their compact metal melting furnace equipment is a game-changer for local foundries, auto repair shops, and artisanal metalworkers.

"SMEs are the backbone of China's economy, but they're often left behind by tech advancements," explains Zhao Li, SmartFoundry's product manager. "Our goal is to level the playing field." Take their MF-500, a medium frequency furnace that fits in a 10x10 meter space and melts 500 kg of aluminum per hour—perfect for a family-run hardware factory in Zhejiang. What makes it smart? An AI-driven control panel that adjusts power and temperature in real time, reducing waste and ensuring consistent melt quality. "Before, we'd lose 10% of metal to overheating or cold spots," says Wu Jian, the factory's owner. "Now, it's less than 2%. We're saving metal, time, and money."

SmartFoundry also offers flexible financing and 24/7 tech support—critical for SMEs with tight budgets and limited technical staff. "A client in Yunnan called us at 2 a.m. because their furnace wouldn't start," Zhao recalls. "Our technician walked them through a diagnostic via video call, and they were back up in 45 minutes. That's the service we pride ourselves on."

5. GlobalRecycle Machinery: Bridging Borders with Compliant Recycling

For businesses exporting recycled materials, compliance is everything. Enter GlobalRecycle Machinery, a Shanghai-based firm that builds recycling equipment to meet the strictest international standards—from the EU's REACH regulations to California's Proposition 65. Their li-ion battery breaking and separating equipment is a hit with clients in Europe and North America, who need to prove every step of their recycling process is safe and traceable.

"We don't just build machines—we build trust," says Sarah Liu, GlobalRecycle's international sales lead. "A German client once told us, 'Your equipment doesn't just separate metals; it separates us from liability.'" Case in point: Their WLR-3000 lithium battery recycling line, which uses dry separation (no water, no chemical waste) to recover 98% of lithium, cobalt, and nickel. Each unit comes with blockchain-enabled tracking software, so clients can show auditors exactly where each material came from and where it's going.

GlobalRecycle also invests in training, hosting workshops for clients in Southeast Asia and Africa on best practices for battery recycling. "Last year, we trained 200 workers in Vietnam," Liu says. "Now their recycling plant meets EU standards, and they're exporting recycled cobalt to European battery makers. That's how we grow—by helping our clients grow globally."
