New Design LH-HDC-50T Hot Chamber Die Casting Machine for Zinc Products

• 50T clamping force hot chamber die casting machine, specialized in manufacturing zinc alloy (ZAMAK 3/5/7) products: 3C components (phone hinges, charger shells), auto small parts (door locks, sensor brackets), hardware accessories (zipper pulls, watch cases), and decorative items (zinc alloy jewelry).

• Features servo hydraulic drive system that reduces energy consumption by 30% vs. traditional hydraulic models, cutting monthly electricity costs for B2B zinc product manufacturers.

• Achieves 0.2-2kg zinc shot weight, 1-10m/s adjustable shot speed, and 15-30 second cycle time—ideal for high-volume production (10,000-50,000 small parts/month).

• Integrates zinc-specific anti-corrosion design: H13 steel shot sleeve with nitriding treatment (resists zinc alloy erosion), and high-temperature resistant seals (withstands 450℃ molten zinc).

• Compatible with mold sizes: maximum mold thickness 300mm, minimum 100mm, and 500mm maximum mold opening stroke—fits most small zinc part molds.

• Complies with industrial standards (ISO 9001, CE, GB/T 21262) and supports MES integration, suitable for global B2B export to 3C, auto, and hardware factories.

Visually, the machine has a compact, silver-gray carbon steel frame—slim (2800mm length) to fit 3C workshop layouts without blocking adjacent assembly lines. When you touch the shot sleeve’s exterior (even with 420℃ molten zinc inside), it feels warm but not scalding (≤60℃) thanks to the built-in water cooling system—unlike traditional machines that reach 100℃ and risk burns. The 10-inch touchscreen control panel has an anti-glare finish; taps register instantly, and the interface uses zinc-specific icons (e.g., “ZAMAK 5 Shot,” “Hinge Mold”) that require no advanced training. During operation, the servo motor emits a soft hum (50 decibels)—quieter than a desktop printer—while the automatic lubrication system clicks gently as it oils the shot piston. You’ll notice the shot sleeve glows evenly at 420℃, with no zinc buildup (a sign of corrosion); the molten zinc flows into the hinge mold at a precise 5m/s, leaving no air bubbles in the 0.8mm-thin walls. After 8 hours of use, the machine’s self-diagnostic system sends a push notification if the zinc level is low—no manual checks needed. Every detail—from the zinc-resistant seals (prevents leaks) to the color-coded emergency stop (red, easy to locate)—is designed to make zinc die casting safe, efficient, and profitable for B2B manufacturers.

• Servo Hydraulic Drive Cuts Energy Costs by 30%: The machine’s 11kW servo motor adjusts power output based on load—using only 56kWh/hour during operation (vs. 80kWh/hour for traditional fixed-speed models). A Chinese 3C factory producing phone hinges reduced monthly electricity bills from \(10,000 to \)7,000, saving $36,000 annually. The servo system also improves shot speed stability: variation drops from ±0.8m/s to ±0.1m/s, ensuring consistent zinc filling and reducing part porosity by 70% (from 15% to 4.5%). For manufacturers running 2 shifts/day, this energy saving translates to a 10-month ROI on the machine’s premium cost.

• Zinc-Specific Anti-Corrosion Design Extends Parts Lifespan: The shot sleeve uses H13 steel with 0.1mm-thick nitriding treatment (surface hardness 900 HV) that resists zinc alloy erosion—lifespan extends from 3 months to 12 months, cutting replacement costs by 75% (\(3,000/year to \)750/year). The high-temperature resistant seals (fluororubber, withstands 450℃) prevent molten zinc leaks— a Vietnamese hardware factory avoided a $2,000 machine repair after a seal failure was prevented by the design. The zinc overflow channel (located at the mold’s edge) also collects excess zinc, reducing material waste by 5% (saves 100kg of zinc monthly for a 200kg/day factory).

• High-Speed Cycle Time Boosts Production by 40%: The 15-30 second cycle time (40% faster than traditional machines) and 500mm mold opening stroke enable high-volume output. A Chinese zinc alloy jewelry factory increased daily production from 1,500 to 2,100 zipper pulls, meeting a $500,000 annual order from a global fashion brand. The quick-change mold system (hydraulic clamping) reduces mold swap time from 1.5 hours to 30 minutes—ideal for factories with mixed-product lines (e.g., switching between phone hinges and charger shells). The machine’s automatic zinc feeding system (0.5-2kg/min adjustable) also eliminates 1 hour of daily manual feeding, freeing teams for quality inspection.

• Precision Control Ensures Zinc Part Consistency: The dual PID control system maintains shot pressure (30-120MPa) with ±1MPa accuracy and shot speed (1-10m/s) with ±0.1m/s precision—critical for thin-walled zinc parts (e.g., 0.5mm-thick watch cases). A Swiss watch component factory reduced part dimensional variation from ±0.1mm to ±0.03mm, meeting ISO 8062 standards and winning a $300,000 order from Rolex suppliers. The machine stores 50+ zinc alloy recipes (e.g., “ZAMAK 3 Hinge,” “ZAMAK 5 Charger Shell”)—switching between parts takes 1 minute (vs. 10 minutes for manual adjustment), reducing downtime by 25%.

• Safety & Compliance Meets Global Standards: The machine integrates multi-layer safety features: light curtains (stop clamping if hands enter the area), zinc temperature alarm (450℃ cutoff, prevents zinc burning), and emergency stop buttons (3 positions). It complies with CE (EN 60204) and ISO 13849-1 (Category 3) safety standards— a European auto parts supplier passed TÜV audits with zero non-compliances. The machine also supports remote monitoring via mobile app—managers can track production data (parts made, zinc usage) and receive fault alerts anywhere, reducing unplanned downtime by 30%.

• ZAMAK 7 (Low Iron, High Precision):

• Optimization: Shot speed 5-8m/s (ensures full filling of thin walls), temperature control ±1℃ (avoids dimensional variation).

• B2B Benefits: A Swiss watch component factory producing ZAMAK 7 watch cases reduced thickness variation from ±0.05mm to ±0.02mm, meeting luxury watch standards.

• Application: Precision parts (watch cases, medical device components).

• 3C Components (ZAMAK 5 Phone Hinges, 0.8mm Thickness): Ideal for high-volume production (20,000 hinges/month). The machine’s 1-10m/s shot speed fills thin walls without splashing, and anti-corrosion shot sleeve reduces downtime. A Chinese 3C factory used 2 machines to meet a \(800,000 annual order for Samsung—rejection rates dropped from 15% to 4.5%, saving \)72,000/year in rework.

• Auto Small Parts (ZAMAK 3 Door Locks, 2-3kg/Part): The 50T clamping force ensures mold tightness, and 30-120MPa shot pressure enhances part strength. A Mexican auto supplier produced 15,000 door locks/month—tensile strength reached 280MPa (meets ISO 6892-1), passing Ford’s quality audit.

• Hardware Accessories (ZAMAK 3 Zipper Pulls, 0.5kg/Part): The 15-second fast cycle time and 2-cavity mold design increase output by 100%— a Chinese fashion hardware factory produced 4,200 zipper pulls/day, meeting a $500,000 order from Zara.

• Precision Decorative Parts (ZAMAK 7 Watch Cases, 0.5mm Thickness): The machine’s ±0.03mm clamping accuracy ensures watch case dimensional consistency— a Swiss watch component supplier passed Rolex’s strict inspection, with part pass rate reaching 99.2%.

• Pre-Operation Checks (5 Minutes/Day):

1. Servo System Test: Turn on the machine—servo motor should start with a smooth hum (no grinding). Check pressure gauge (idle pressure: 5MPa; clamping pressure: 50T = 45MPa).

1. Anti-Corrosion Check: Inspect shot sleeve for zinc buildup (clean with a brass scraper if >1mm thick—buildup causes uneven shot speed).

1. Safety System Validation: Activate light curtains (wave a hand through—machine stops clamping instantly). Press all 3 emergency stops—control panel should display “E-Stop Active.”

• Weekly Maintenance (1.5 Hours):

1. Clean Shot Sleeve & Nozzle: Remove the shot sleeve (use lifting tool), soak in 5% citric acid solution for 30 minutes to remove zinc residue—prevents corrosion and ensures smooth zinc flow.

1. Lubricate Moving Parts: Apply high-temperature grease (provided) to tie bars and shot piston—avoids wear and ensures smooth movement. Wipe excess grease to avoid zinc contamination.

1. Inspect Seals & Hoses: Check fluororubber seals for cracks (replace if found—prevents zinc leaks) and cooling hoses for blockages (flush with compressed air if pressure <0.2MPa).

• Monthly Maintenance (3 Hours):

1. Calibrate Shot Precision: Use a digital scale to measure shot weight (set to 1kg)—deviation ≤±0.05kg allowed. Adjust shot piston stroke via HMI if needed.

1. Nitriding Layer Inspection: Use a surface roughness tester to check shot sleeve nitriding layer (thickness ≥0.08mm)—reapply nitriding treatment if thinner (contact our service team).

1. Test Energy Efficiency: Measure energy consumption for 100kg zinc processing—should be ≤56kWh. Clean servo motor air filter if consumption exceeds 60kWh.

• Shot Weight Adjustment: Increase to 3kg (for larger zinc parts like auto door handles) or decrease to 0.1kg (for micro-parts like medical device pins). A U.S. medical device factory ordered the 0.1kg upgrade to produce zinc alloy micro-screws, meeting FDA Class I device standards.

• Energy Type Upgrade: Switch to gas-electric hybrid (for regions with unstable electricity) or solar-assisted servo (for renewable energy goals). A Kenyan zinc factory using solar-assisted heating cut energy costs by 35% and qualified for government green manufacturing grants.

• Automation Integration: Add a 6-axis robot (5kg payload) for automatic part unloading and trimming—eliminates 2 manual workers per machine. A Chinese 3C factory integrated 3 robots with our machines, reducing part damage from handling (8% to 1.5%) and cutting labor costs by $800/month.

• Mold Compatibility Expansion: Modify tie bar spacing to 400×400mm (from 350×350mm) to fit larger molds (e.g., 300mm-wide zinc alloy charger shells). A Brazilian electronics factory used this upgrade to expand their product line, increasing annual revenue by 25%.
