Product Description
High-Conductivity Copper Die-Castings For EV Chargers
Core Product Value: Outstanding Performance Forged by High-Pressure Technology
This series of die-cast components is built on the core technology of high-pressure and high-speed die-casting process. Molten metal is injected into custom molds at an initial speed of 0.5-70 m/s under a pressure ranging from several megapascals to dozens of megapascals, followed by instantaneous filling (0.01-0.03 seconds) and rapid cooling for molding.
Density & Toughness: The grain structure solidified under pressure is refined, with a porosity controllable below 1%. Its strength and hardness are far superior to traditional cast parts, and its corrosion resistance and fatigue resistance are significantly enhanced.
High Efficiency & Economy: Mechanized and automated production enables short-cycle mass manufacturing. Compared with processes like forging, the cost is reduced by more than 30%, the metal utilization rate reaches 95%, and waste materials can be 100% recycled and remelted.
Flexible Customization: It can meet full-size requirements from micro thin-walled parts to extra-large structural components, supporting integrated molding of complex curved surfaces, ribs, threads, etc., and reducing subsequent assembly processes.
Diverse Material Systems: Accurately Matching Scenario Requirements
Based on differences in application environments, we provide four categories of core material solutions, covering all types of scenarios from general industry to high-end manufacturing.
Aluminum Alloy: As a widely used die-casting material, it has a density of only 2.7 g/cm³, which is 60% lighter than steel. Meanwhile, it possesses excellent corrosion resistance, superior electrical and thermal conductivity, and can be fully recycled and reused. In practical applications, it is often used in key components such as automobile engine blocks, 5G base station radiators, and high-speed rail seat frames.
Zinc Alloy: It is distinguished by good ductility and a smooth surface texture, capable of accurately forming thin-walled parts with a thickness of only 0.3 mm. Moreover, it causes less wear to molds during production, effectively extending the service life of molds.
Magnesium Alloy: It is an ideal choice for scenarios requiring lightweight properties, with a density as low as 1.8 g/cm³. While ensuring lightweight, it has an extremely high strength-to-weight ratio and excellent shock absorption performance.
Copper Alloy: Its core advantage lies in excellent electrical conductivity, with a conductivity of up to 85% IACS. At the same time, it has high toughness, capable of withstanding a certain degree of impact and wear, and possesses good corrosion resistance.
Note: Lead-tin alloy is only used in non-food contact scenarios, and is mostly used as an alloy additive to improve corrosion resistance.
Precision Process Control: Defining Industry Precision Standards
Relying on full-process digital management and control, precise control from mold design to finished product delivery is achieved:
Dimensional Precision: Reaching IT8-IT11 grade, the tolerance can be controlled within ±0.1 mm, the minimum cast hole diameter is only 0.7 mm.
Surface Quality: After high-pressure filling and mold polishing, the surface finish can reach Ra1.6 μm, supporting subsequent surface strengthening treatments.
Process Upgrading: Vacuum die-casting technology can be optionally adopted to reduce pore defects, increasing the fatigue life of components by 3-5 times.
Full-Field Applications: Empowering the Upgrade of High-End Manufacturing
Automotive Industry: Integrated die-cast body floor panels, battery casings, and motor housings, achieving a dual improvement of 30%-50% weight reduction and sealing performance.
Transportation & High-End Equipment: Bogie gearbox casings and brake system components, meeting the EN 45545 fire protection standard and the requirements of high-frequency vibration working conditions.
Electronics & Precision Manufacturing: Thin-walled die-cast radiators (with a wall thickness of 0.5 mm) and mobile phone middle frames, realizing efficient heat conduction and electromagnetic shielding.
