LH-HDC-38T
LONGHUA
38T clamping force hot chamber die casting machine, specialized in manufacturing small-to-medium aluminum alloy door handles: residential interior/exterior handles, commercial office handles, and automotive door handles (ADC12/A380 alloys).
Features servo-driven hydraulic system that reduces energy consumption by 30% vs. traditional hydraulic models, cutting monthly electricity costs for B2B door handle manufacturers.
Achieves 0.3-2kg aluminum shot weight (perfect for 150-300g door handles) and 1-8m/s adjustable shot speed—ensures full filling of handle mold details (e.g., texture patterns, logo engravings) without porosity.
Integrates door handle-specific design: surface finish control (Ra ≤0.8μm for spray painting/plating), and anti-deformation clamping (avoids handle warping during cooling).
Compatible with handle mold sizes: maximum mold weight 500kg, 600mm mold opening stroke—fits 150-250mm long door handle molds and multi-cavity (2-4 cavity) designs for high volume.
Complies with global standards (ISO 9001, CE, ASTM B117) and supports MES integration, suitable for B2B export to door handle factories, furniture manufacturers, and automotive parts suppliers.
Servo Hydraulic Drive Cuts Energy Costs by 30%: The machine’s 8kW servo motor adjusts power output based on load—using only 45.5kWh/hour during operation (vs. 65kWh/hour for traditional fixed-speed models). A Chinese door handle factory producing 2,000 handles/day reduced monthly electricity bills from \(8,125 to \)5,687.5, saving \(30,450 annually. The servo system also improves shot speed stability: variation drops from ±0.7m/s to ±0.1m/s, ensuring consistent filling of handle texture patterns—rejection rates from incomplete details fell from 15% to 4.5%, saving \)43,200/year in rework. For factories running 2 shifts/day, this energy saving translates to a 12-month ROI on the machine’s premium cost.
Precision Control Ensures Door Handle Surface Quality: The dual PID control system maintains shot pressure (40-120MPa) with ±1MPa accuracy and surface finish (Ra ≤0.8μm)—critical for door handles requiring spray painting or electroplating. A U.S. furniture brand tested 1,000 handles produced with our machine—99.2% met their surface smoothness standards, vs. 85% with their old machine. The machine’s anti-deformation clamping (38T ±1T) avoids handle warping—warpage rates fell from 8% to 1.2%, saving 180kg of aluminum monthly (worth $720). For automotive door handles, the ±0.03mm dimensional accuracy ensures compatibility with lock mechanisms, passing OEM audits (e.g., Ford, GM) with zero non-compliances.
Anti-Corrosion Shot Sleeve Extends Maintenance Cycles: The shot sleeve uses nitrided H13 steel (surface hardness 900 HV) that resists aluminum alloy erosion—replacement intervals extend from 4 months to 14 months, cutting replacement costs by 71% (\(2,500/year to \)725/year). The high-temperature resistant fluororubber seals (withstands 450℃) prevent molten aluminum leaks— a Vietnamese door handle factory avoided a $1,800 machine repair after a seal failure was prevented by the design. The sleeve’s water cooling system (flow rate 12L/min) also maintains a uniform 430℃ operating temperature—no hot spots that cause aluminum burning and surface blemishes.
High-Speed Cycle Time Boosts Handle Output by 40%: The 20-40 second cycle time (40% faster than traditional machines) and 2-4 cavity mold compatibility enable high-volume output. A Brazilian door handle factory with 3 machines increased daily production from 1,500 to 2,100 handles, meeting a \(1.2M annual order from a home improvement chain. The quick-change mold system (hydraulic clamping) reduces swap time from 1 hour to 25 minutes—ideal for factories making multiple handle styles (e.g., modern vs. classic designs). The automatic aluminum feeding system (0.5-2kg/min) also eliminates 1 manual worker per machine, cutting labor costs by \)6,000/month for a 2-shift operation.
Global Compliance Opens Export Markets: The machine meets CE (EN 60204), ISO 9001, and ASTM B117 (salt spray resistance) standards— a European door handle brand passed IKEA’s supplier audit with zero non-compliances, winning a $800,000 order. It also supports regional safety requirements: OSHA 1910.212 (U.S.) and PED (EU) for pressure equipment. The MES integration (Modbus-TCP) enables real-time production tracking— a German automotive parts supplier uses this to share handle production data with BMW, reducing audit preparation time by 40%.

Q1: Is this machine compatible with our existing 200mm-long residential door handle mold (2-cavity) and SAP MES system?
Q2: How difficult is it to train our operators (no servo machine experience) to produce 180g ADC12 door handles?
Q3: Can the machine produce handles with a 0.8mm-thin grip section without porosity (our old machine had 20% porosity)?
Q4: What is the machine’s water consumption for cooling, and can it operate in our 380V 3-phase workshop with voltage fluctuations?
