Die-casting workshop

Equipment configuration: Using Toshiba’s 8,000-ton fully automatic die-casting island (including 160-400-ton models) and a robotic arm automatic pick-up system to achieve 24-hour unmanned production;

Process accuracy: mold accuracy ±0.02mm (industry average ±0.05mm), combined with ultrasonic dewaxing process to completely remove mold residues;

Quality inspection: X-ray flaw detection (in accordance with ISO 17636 standards) detects internal porosity <0.1%, and the yield rate exceeds 99.5%;

CNC machining workshop

Equipment combination: VMC850E five-axis linkage machining center (repeat positioning accuracy ±0.005mm) + online laser measurement system (Renishaw RMP60);

Processing capability: precision machining of special-shaped curved surfaces (roundness ≤ 0.002mm), supporting difficult-to-cut materials such as titanium alloy and nickel-based alloy;

Closed-loop control: real-time compensation of thermal deformation errors through the Heidenhain TNC system, and the key dimensional tolerance is stable at ±0.01mm;

Surface treatment workshop

Anodizing: hard anodizing process (film thickness 25-30μm, hardness HV ≥ 180), salt spray resistance test up to 120 hours;

Environmental protection process: cyanide-free electroplating line (nickel layer thickness 5-8μm), wastewater treated by RTO regenerative incinerator (VOC removal rate > 98%);

Intelligent spraying: seven-axis robot electrostatic spraying (film thickness 50±5μm), color difference ΔE＜1.5 (automotive industry requires ΔE＜1.7);

Certification guarantee: passed SGS environmental protection testing (RoHS, REACH), and obtained ISO 14001:2015 certification.

Assembly and welding workshop

Welding technology: IPG YLS-5000 fiber laser welding (weld depth-to-width ratio ≥6:1), argon arc welding automation rate reaches 80% (six-axis robot);


Seal detection: Helium mass spectrometer leak detector sensitivity 1×10⁻⁹ Pa·m³/s, leakage rate <1×10⁻⁸ Pa·m³/s (automotive grade standard);


Reliability test: Passed 100,000 vibration tests (frequency 10-50Hz, acceleration 5g), key component life > 50,000 hours;

Testing and quality inspection workshop

Environmental simulation: high and low temperature cycle test chamber (-40℃~150℃, heating and cooling rate 10℃/min), simulating extremely cold/hot environment;

Salt spray test: neutral salt spray test machine (48 hours without white rust, automotive parts additional copper accelerated acetic acid salt spray test CASS 72 hours);

Failure analysis: CNAS L11297 laboratory supports SEM scanning electron microscopy (resolution 1nm), EDS energy spectrum analysis (element detection limit 0.1%);

Traceability system: MES system records 200+ process parameters, and quality problems are located to specific processes within 30 minutes.

Fully automatic production line

Cold needle winding: Japan Sodick R series winding machine (accuracy ±0.02mm), supports 0.1mm ultra-fine nickel-chromium wire winding;


Production rhythm: Fully automatic cold needle winding wire production capacity is 1,200 pieces/hour, and the efficiency is 50% higher than that of manual work;


Intelligent traceability: MES system scans the code to bind the production batch (including material furnace number, operator ID), and supports full life cycle traceability;


Capacity data: Monthly production capacity is 3 million pieces (single shift), and urgent orders can be delivered within 72 hours (48 hours notice is required in advance).
