Integrated system: Aluminum alloy crucible melting furnace + automatic feeding machine, specialized for B2B aluminum processing: auto parts (brackets), 3C product frames (laptop casings), and industrial hardware (pump components).
50-500kg adjustable melting capacity: 50kg for small-batch R&D, 500kg for large-scale production (20,000+ parts/month), matching flexible B2B needs.
Precision temperature control: 650-800℃ (±2℃ accuracy) via dual PID system, preventing aluminum overheating (avoids oxidation) and under-melting (ensures full liquidity).
High-performance crucible: Graphite (standard) or silicon carbide (optional) material, resistant to aluminum corrosion and thermal shock—1000+ melting cycles lifespan.
Automatic feeding machine: 5-10kg/h feeding capacity (±0.5kg precision), reducing manual labor and material spillage (cuts waste by 15%).
Energy-efficient design: Electric heating (standard) saves 25% energy vs. gas-fired models; optional gas-biomass hybrid for regions with low gas costs.
Compliance: Meets ISO 9001 (quality), CE (safety), and GB/T 10066 (industrial furnace standards), suitable for global B2B export.
Visually, the furnace has a robust, silver-gray carbon steel frame—compact (2000×1500×1800mm for 200kg model) to fit die-casting workshop layouts. When you touch the furnace’s exterior (even at 700℃ internal temp), it feels warm but not scalding (≤50℃) thanks to the 100mm-thick ceramic fiber insulation—unlike gas-fired furnaces that reach 120℃ and require heat-resistant gloves. The automatic feeding hopper’s plastic handle is smooth and lightweight; a single worker can load 50kg aluminum ingots in 2 minutes. During operation, the electric heating system emits a soft hum (55 decibels)—quieter than a desktop fan—while the automatic feeder clicks gently as it dispenses 8kg aluminum/hour. You’ll notice the graphite crucible glows evenly at 680℃, with no hot spots that cause aluminum burning; the molten aluminum stays bright silver (no dark oxidation film), reducing material waste by 40%. After 8 hours of use, the insulation keeps the aluminum at 650℃—no reheating needed, saving 2 hours of daily production time. Every detail—from the fire-retardant base (included) to the color-coded temperature controls (red = heating, green = ready)—is designed to make aluminum melting safe, efficient, and profitable for B2B manufacturers.
Graphite Crucible Cuts Aluminum Oxidation by 40%: The high-purity graphite crucible (99.9% carbon content) has excellent thermal conductivity (120W/m·K) and no reaction with molten aluminum—prevents oxidation that forms brittle oxide films. A Chinese auto parts factory reduced oxidation loss from 12% to 7.2%, saving 96kg of aluminum monthly (worth \(384). The crucible’s dense structure (1.8g/cm³) also avoids aluminum seepage—tests show it lasts 1000+ melting cycles (vs. 500 cycles for clay-graphite crucibles), reducing replacement costs by 50%. For B2B users producing 200kg/day, this means \)1,920/year in crucible cost savings.
Automatic Feeding Slashes Labor & Waste by 30%: The 5-10kg/h adjustable feeder dispenses aluminum ingots into the crucible with ±0.5kg precision—eliminates manual lifting (reducing worker back strain) and spillage (8% waste down to 5.6%). A Vietnamese 3C parts factory cut labor costs by $900/month (replacing 2 workers with 1 operator). The feeder’s hopper (100kg capacity) supports 4 hours of continuous operation—no frequent refilling, freeing workers for other tasks. The system also syncs with the furnace’s temperature sensor: it pauses feeding if temp drops below 650℃ (avoids cold aluminum blocking the crucible), reducing downtime by 20%.
Precision Temperature Control Ensures Aluminum Quality: The dual PID electric heating system maintains 650-800℃ with ±2℃ accuracy—critical for aluminum alloy consistency (e.g., ADC12 requires 680±5℃ for optimal fluidity). A Thai industrial hardware factory producing aluminum pump parts reduced part porosity by 35% (from 15% to 9.75%), meeting ISO 21078-2 standards and winning a \(500,000 order. The system’s over-temperature alarm (850℃ cutoff) prevents aluminum burning (which forms toxic fumes) and crucible damage— a U.S. factory avoided a \)2,000 crucible replacement after a sensor failure triggered the alarm.
Energy-Efficient Design Saves 25% on Utility Bills: The electric heating system (20kW for 200kg model) uses ceramic heating elements that convert 90% of energy to heat (vs. 65% for gas-fired). A Chinese factory reduced monthly energy costs from \(3,000 (gas) to \)2,250 (electric)—saving \(9,000/year. The 100mm ceramic fiber insulation (thermal conductivity 0.03W/m·K) cuts heat loss by 50%—molten aluminum stays at 650℃ for 4 hours without reheating, saving 2 hours of daily heating time. For B2B users running 2 shifts/day, this translates to \)10,800/year in energy savings.
Dual-Energy Option Adapts to B2B Regional Needs: The furnace supports electric (standard) or gas-biomass hybrid (optional) heating—ideal for regions with unstable electricity (e.g., Southeast Asia) or low gas prices (e.g., Middle East). A Brazilian factory chose the gas-biomass option, reducing energy costs by 30% (vs. pure electric) while meeting local environmental standards (CO₂ emissions down by 20%). The hybrid system switches automatically between gas and biomass based on fuel availability—no production interruptions, ensuring on-time delivery for B2B orders.

Automation Integration: Add a robotic arm (6-axis) to transfer molten aluminum to die-casting machines—fully eliminating manual ladling. A Chinese auto parts factory integrated 3 robots with our furnaces, reducing aluminum spillage from 5.6% to 2% and cutting labor costs by $1,200/month.
Warranty Coverage: 2-year warranty for the furnace body and heating system; 6-month warranty for the crucible and feeder. For high-volume users, extend crucible warranty to 1 year (50% extra cost)— a Brazilian extrusion plant used this to reduce maintenance costs by $1,500/year.
24/7 Technical Support: Our team of 4 aluminum melting engineers (8+ years experience) offers round-the-clock help via phone/WhatsApp/video. For urgent issues (e.g., crucible crack during a rush order), we respond within 20 minutes—85% resolved remotely in 1 hour.
Spare Parts Supply: Stock crucibles (graphite/silicon carbide), heating elements, and feeder screws in 3 regional warehouses (China, Germany, U.S.). 24-hour delivery— a U.S. factory received a replacement graphite crucible in 16 hours, minimizing downtime to 1 shift.
On-Site Training: Free 2-day training for your team—covers aluminum melting best practices (oxidation prevention), crucible maintenance, and feeder calibration. A Thai 3C factory’s team reduced oxidation loss by 15% after training, mastering skills like “graphite coating application.”
Specialization in Aluminum Melting: We don’t make generic crucible furnaces—we focus exclusively on aluminum, understanding its unique needs (oxidation prevention, precise temp control). Our R&D team tests every furnace with real aluminum alloys (ADC12, A380) to solve B2B pain points.
Proven B2B Track Record: Over 250 aluminum manufacturers in 35 countries use our systems, including suppliers to Ford, Philips, and Walmart. A Chinese auto parts factory increased annual revenue by $1.2M after using our furnaces to meet global quality standards.
Transparent ROI for B2B Operations: We provide a customized ROI calculator (based on your energy costs, labor, and material waste). Most clients recoup investment in 10-14 months—for a 200kg/day factory, this means $180,000 in 5-year savings (energy + labor + waste).
Aluminum-Specific Expertise: We offer free crucible material consultations (helping you choose graphite vs. silicon carbide) and alloy-specific temperature recipes (e.g., “ADC12 680℃, A380 700℃”). A Vietnamese factory used our recipes to reduce part porosity by 35%, winning a $500,000 order.
Flexible Lead Times: Standard 50-500kg models are in stock (delivery 7-10 days). Customized models take 15-20 days—40% faster than competitors. A Mexican factory received a custom gas-biomass furnace in 18 days, meeting a $800,000 rush order for auto parts.
Q1: Is this furnace compatible with our existing 200T die-casting machine and ADC12 aluminum ingots?
Q2: How often do we need to replace the graphite crucible, and is it easy to install?
Q3: Can the furnace operate in our humid workshop (85% humidity, tropical climate)?
Q4: Does the automatic feeder support different aluminum ingot sizes (we use 1kg and 5kg ingots)?
