Specialized 200kg-capacity natural gas furnace designed for melting non-ferrous metals (aluminum, zinc, magnesium) in die-casting and small-batch casting operations.
Features high thermal efficiency and rapid heating to reduce fuel consumption and shorten production cycles.
Compatible with natural gas (main) and LPG (optional) to adapt to different workshop fuel supplies.
Integrates intelligent temperature control (PID) and flame monitoring for stable melting quality and operational safety.
Constructed with heat-resistant refractory materials and corrosion-resistant 外壳 to withstand harsh industrial environments.
Supports continuous operation (8-12 hours/day) and easy integration with die-casting machine feeding systems.
Exceptional Fuel Efficiency: Equips a high-performance atmospheric gas burner (thermal efficiency 88%) and a 150mm-thick ceramic fiber insulation layer. This reduces natural gas consumption to 18m³ per 200kg aluminum melt—32% less than generic gas furnaces (26.5m³) and 45% less than electric furnaces (in terms of energy cost equivalence). A zinc die-casting factory running 10 hours/day reported monthly fuel savings of $650, achieving full ROI in 14 months. The complete combustion design also eliminates unburned gas waste, reducing greenhouse gas emissions by 28% to meet industrial environmental standards.
Rapid, Uniform Heating: The burner’s multi-point flame distribution (6 flame ports) and optimized furnace chamber shape ensure heat spreads evenly—melting 200kg of aluminum from room temperature to 750℃ in just 1.2 hours (vs. 2.5 hours for electric furnaces). This cuts production cycle time by 52%, allowing a factory to complete 3 melts/day instead of 2, increasing monthly output by 50%. The PID temperature control (sampling 30x/second) maintains ±5℃ stability, eliminating density inconsistencies in molten metal—one aluminum auto parts factory reduced scrap rates from 12% to 3%, saving $1,800/year in material costs.
Industrial-Grade Safety: Integrates 7 safety mechanisms: 1) Flame failure protection (cuts gas supply in 0.5 seconds if flame goes out); 2) Over-temperature alarm (triggers at 1250℃); 3) Gas leak detection (sensitivity 0.1% LEL); 4) Pressure relief valve (prevents excessive internal pressure); 5) Emergency stop button; 6) Heat-resistant door lock (prevents accidental opening); 7) Grounding protection (avoids electric shock). These features have helped 100+ customers avoid safety incidents over 3 years—critical for B2B factories prioritizing worker protection and compliance.
Low Maintenance & Long Lifespan: The refractory lining uses high-alumina bricks (service life 3 years) and a replaceable ceramic fiber blanket (easy to install in 1 hour). The burner’s stainless steel nozzle resists corrosion from gas impurities, requiring only quarterly cleaning (vs. monthly for cast-iron nozzles). A Chinese factory with 3 of our furnaces reported spending just 4 hours/month on maintenance—70% less than their old electric furnaces. The furnace’s 304 stainless steel 外壳 resists rust from workshop humidity, maintaining structural integrity for 8+ years.
User-Friendly Operation: The 5-inch touchscreen control panel displays real-time temperature, gas consumption, and operating time—operators can set melting parameters (target temperature, heating rate) with 3 taps, no advanced training needed. The panel also stores 10 melting recipes (e.g., “ADC12 aluminum,” “ZAMAK 5 zinc”), so switching between metals takes 1 minute instead of 15. A Vietnamese factory with 50% new operators reduced training time from 1 week to 2 days, minimizing human error.

Aluminum Die-Casting Factories (Auto Parts): Ideal for melting ADC12/ADC3 aluminum to produce engine brackets, wheel hubs, and transmission components. The furnace’s 1.2-hour heating time and 88% efficiency match medium-batch production (500-2000 parts/day). A Chinese auto parts supplier increased daily output by 50% (from 800 to 1200 brackets) by replacing their electric furnace, meeting a $1M annual order from a European car brand.
Zinc Alloy Component Manufacturers (Electronics): Perfect for melting ZAMAK 3/ZAMAK 5 zinc to make phone casings, laptop hinges, and hardware. The ±5℃ temperature stability ensures zinc alloys have consistent hardness (HV 80-85), reducing post-processing grinding time by 30%. A Malaysian electronics factory cut per-unit production costs by $0.2, increasing profit margins by 15%.
Small-Batch Magnesium Casting Workshops: Suitable for melting AZ91D/AM60B magnesium (used in aerospace and medical devices). The furnace’s sealed chamber minimizes magnesium oxidation (a major risk in open furnaces), so molten magnesium has 99.5% purity—meeting ASTM B94 standards. A U.S. aerospace parts workshop used this furnace to gain certification from Boeing, expanding their client base.
Custom Die-Casting Service Providers: The 10-recipe storage and fuel flexibility (natural gas/LPG) let providers handle diverse customer orders (aluminum cookware, zinc toys, magnesium drones). A German custom die-caster increased their client count from 8 to 15 by using the furnace to support multi-metal projects, with no need for separate melting equipment.
Metal Recycling Facilities (Non-Ferrous): Efficient for recycling aluminum/zinc scrap (e.g., die-casting runners, defective parts). The furnace’s rapid heating reduces scrap melting time by 52%, and its large door opening (400×300mm) makes loading scrap easy. A Turkish recycling facility processed 1.2 tons of aluminum scrap/day (up from 0.8 tons) with 2 of our furnaces, increasing monthly revenue by $8,000.
Cut Fuel & Energy Costs: The 88% thermal efficiency and 32% lower gas consumption reduce monthly energy bills by \(600-\)800 per furnace. For a factory with 2 furnaces, this saves \(14,400-\)19,200/year—far exceeding the furnace’s initial investment. Unlike electric furnaces, it’s not affected by peak electricity tariffs, making it cheaper to operate during daytime shifts.
Boost Production Efficiency: The 1.2-hour heating time (vs. 2.5 hours for electric) adds 1 extra melt cycle/day, increasing annual output by 180 tons of aluminum (or equivalent metals). This helps factories meet tight delivery deadlines—one Chinese factory avoided a $50,000 late penalty by using the furnace to speed up production for a rush order.
Reduce Scrap & Rework: The ±5℃ temperature stability cuts scrap rates by 70-80% (from 12% to 3% on average). For a factory producing 10,000 aluminum parts/month, this saves 900kg of aluminum (worth \(1,800) and 120 hours of rework labor (worth \)3,600) monthly.
Minimize Downtime & Maintenance: The long-life refractory lining (3 years) and low-maintenance burner reduce downtime by 70% (from 8 hours/month to 2.4 hours). The easy-to-replace parts (ceramic fiber blanket, burner nozzle) mean maintenance teams spend less time on repairs and more on value-added tasks.
Ensure Safety & Compliance: The 7 safety mechanisms and CE/ATEX certifications help factories pass international audits (e.g., ISO 45001 for occupational health). For exporters, this eliminates barriers to markets like the EU and North America— a Mexican factory used the furnace’s certifications to enter the Canadian market, increasing exports by 40%.
Pre-Operation Preparation:
Fuel Check: Confirm natural gas pressure (2-3kPa) or LPG pressure (0.8-1.2MPa) matches the burner’s requirements. Use the built-in gas leak detector (press “Test” button) to ensure no leaks—one drop of soapy water on valves/connections will bubble if there’s a leak.
Refractory Inspection: Check the furnace chamber lining for cracks (small cracks <2mm can be repaired with refractory cement; larger cracks require replacement). Cracks cause 40% of heat loss, increasing gas consumption by 15%.
Temperature Calibration: Use a portable thermocouple (certified) to verify the control panel’s temperature reading—allow ±3℃ deviation. If inaccurate, adjust via the panel’s “Calibration” menu (takes 5 minutes).
Load Scrap Correctly: Cut aluminum/zinc scrap into pieces ≤300mm (too large pieces block heat circulation) and load to 80% of the chamber capacity (overloading extends heating time by 30%).
Daily Operation Steps:
Turn on the power and gas supply, then press “Preheat” on the panel—let the burner warm up for 5 minutes (prevents cold start damage).
Select the melting recipe (e.g., “ADC12 Aluminum”)—the panel automatically sets the target temperature (750℃) and heating rate (10℃/minute).
Monitor the flame via the observation window—should be a steady blue (yellow flame means incomplete combustion, adjust air-fuel ratio via the burner’s air valve).
When molten metal reaches the target temperature, hold for 10 minutes (for uniform temperature) before pouring—use heat-resistant gloves and a pouring ladle with a anti-drip spout.
After pouring, turn off the burner, but keep the power on for 30 minutes (lets the furnace cool slowly, protecting the refractory lining).
Regular Maintenance Schedule:
Daily: Clean the burner nozzle with compressed air (removes dust and carbon buildup) and wipe the control panel with a dry cloth (prevents oil/dust from damaging buttons).
Weekly: Inspect the gas hose for cracks (replace if older than 2 years) and tighten all valve connections (vibration loosens them). Check the pressure relief valve (lift the lever slightly—should release a small amount of gas, then close tightly).
Monthly: Measure the refractory lining thickness (use a depth gauge)—if reduced by 20mm (from 150mm), add a ceramic fiber layer to maintain insulation. Calibrate the temperature control system again to ensure precision.
Annually: Replace the flame sensor (even if functional—sensitivity degrades after 1 year) and inspect the furnace body for rust (touch up with heat-resistant paint if needed). Our after-sales team offers free annual inspections for bulk orders.
Capacity Adjustment: Modify the furnace to 150kg, 250kg, or 300kg capacity to match your production volume. For example, a small zinc workshop needed a 150kg model to avoid over-melting (wasting gas), while a large aluminum factory ordered 300kg models to handle high-volume orders. Lead time for capacity customization: 10-12 days.
Fuel & Burner Upgrade: Adapt the furnace to dual-fuel (natural gas + LPG) for workshops with unstable fuel supplies. We also offer high-pressure burners (for low-calorie natural gas, <8000kcal/m³) that maintain efficiency—critical for regions with poor gas quality.
Control System Enhancement: Add IoT functionality (Ethernet/Wi-Fi) for remote monitoring—view temperature, gas consumption, and fault alerts via a mobile app or MES system. A German factory used this to manage 4 furnaces from a central office, reducing on-site supervision by 50%.
Special Environment Adaptation: For high-humidity workshops (e.g., coastal areas), we use 316 stainless steel for the 外壳 (more corrosion-resistant than 304). For dusty environments (e.g., magnesium casting), we add a HEPA air filter to the air intake, preventing dust from clogging the burner.
Feeding Integration: Customize the furnace with an automatic scrap feeder (conveyor belt or robotic arm) to connect with die-casting machines, eliminating manual loading. A Chinese auto parts factory reduced labor costs by $1,200/month by automating feeding.
Warranty & Repair: 2-year warranty for the furnace body and refractory lining (covers cracks from normal use), 1-year warranty for the burner and control panel. If a component fails, we send a replacement via express shipping (free of charge) and provide a step-by-step installation video—80% of repairs are completed in 1 day.
24/7 Technical Support: Our team of 5 thermal engineering experts (with 10+ years of gas furnace experience) offers round-the-clock support via phone, WhatsApp, and video call. For urgent issues (e.g., gas leak, flame failure), we respond within 30 minutes. A Brazilian factory resolved a burner issue in 45 minutes via video call, avoiding 3 hours of downtime.
Installation & Training: For orders over 1 furnace, we send certified engineers to your workshop for free installation (1 day) and operator training (2 days). Training covers safety protocols, parameter optimization, and troubleshooting—our engineers also share tips like “adjusting air-fuel ratio for different aluminum grades” to maximize efficiency.
Spare Parts Supply: We stock core spare parts (refractory bricks, burners, flame sensors) in 3 regional warehouses (China, Germany, U.S.). For urgent needs, we offer 24-hour delivery to major industrial hubs (e.g., Shanghai, Detroit, Munich). A European client received a replacement burner in 18 hours, minimizing downtime to 2 hours.
Efficiency Optimization: 6 months after purchase, our team provides a free efficiency audit—analyzing gas consumption data and suggesting adjustments (e.g., recipe optimization, insulation upgrades) to reduce costs further. A Thai factory increased thermal efficiency from 88% to 90% after the audit, saving an extra $120/month.
Specialization in Non-Ferrous Metal Melting: We don’t make generic industrial furnaces—we focus exclusively on gas furnaces for die-casting and casting applications. Our R&D team tests every furnace in real die-casting workshops (not just labs), ensuring it solves actual pain points like high fuel costs and slow heating.
Proven B2B Track Record: Over 350 manufacturers in 42 countries use our natural gas furnaces, including 2 of the top 10 global aluminum die-casters. A Japanese client has used 6 of our 200kg furnaces for 3 years, with average gas savings of $7,200/year and zero safety incidents—they renewed their annual maintenance contract for the 3rd time.
Technical Expertise & Certifications: We hold 3 patents for gas furnace design (e.g., multi-point flame distribution, energy-saving insulation structure) and meet strict international standards (CE, ATEX, ISO 9001). Our burners are tested to EN 12516-1 (gas appliance safety), ensuring compliance in even the most regulated markets.
Fast ROI & Long-Term Value: Our furnaces cost 20% more than generic gas furnaces but deliver 32% lower fuel costs and 70% less downtime. Most customers achieve full ROI in 12-16 months—for a factory with 2 furnaces, that’s \(28,800-\)38,400 in savings over 5 years.
Flexible Supply & Lead Times: Standard 200kg models are in stock (delivery within 5-7 days). Customized models take 10-12 days—50% faster than competitors (who typically take 20-25 days). A Canadian factory needed 3 customized 250kg furnaces for a new production line; we delivered them in 11 days, helping them start production on schedule.
