In the case of Automobile Precision Stamping Parts for new energy vehicles with 0.05mm burrs, high-voltage batteries are the forbidden zone. In the case of hydrogen fuel tanks, which require a deep drawing ratio of 12:1, the EDM mold process is shaping 1500MPa hot-formed steel with a terrifying accuracy of ±0.0018mm, making it as precise as liquid!
When traditional hydraulic presses leave fatal microcracks on ultra-high-strength steel, and when laser cutting causes stress concentration on the door anti-collision beam, our 24-axis intelligent EDM system is using 0.008mm tungsten wire to carve out a 0.1mm reinforcement array on 65HRC mold steel that is more precise than blood vessels! Body structural parts, high-voltage electric drive housings, airbag triggers... These "hell orders" that once made Japanese suppliers kneel down collectively have achieved zero-defect delivery in 12 hours!
● Quantum Pulse Shaping: 0.000015-second discharge control, stamping die roughness reaches Ra0.03μm
● Intelligent Stress Annihilation System: Dynamically track material flow trajectory, 1.5GPa ultra-high strength steel thinning rate locked ±0.8%
● Trillion-ton stamping black box: 7-layer composite sheet deep drawing one-time forming, wrinkle rate zero
● Nano-level life matrix: gradient coating technology allows mold life to exceed 5 million times
● Defect Prediction AI Cloud Brain: 48 hours in advance warning of 0.001mm potential risks
A German luxury car brand hydrogen fuel bipolar plate stamping die requires 0.2mm thick titanium foil 1286 flow channels with zero error. The yield rate of traditional technology is 0%. We launched the multi-axis mixed gas EDM solution and achieved a yield rate of 99.9% in three days, ending the 20-year technology monopoly of Japanese suppliers!
From 0.5mm ultra-thin electric drive yoke to 25mm armor-grade B-pillar, from hydrogen fuel bipolar plate to aerospace-grade suspension module, 21,356 extreme cases roar: When traditional technology faces the dual difficulties of strength and precision, EDM can balance the relationship between the two well!
