Aluminum Cold Chamber Die Casting Machine for EV High Voltage Power Distribution Housing

Specialized in manufacturing lightweight, high-rigidity 3-in-1 EV on-board power unit housings, this 400-ton cold chamber die casting machine targets weight reduction demands for new energy vehicles. OBC DC-DC PDU integrated die casting housings must reduce overall weight to extend vehicle driving range, while retaining sufficient structural rigidity to withstand road vibration, impact and high-voltage component loads. This 400T equipment realizes thin-wall integrated high-density forming of aluminum power module shells, cutting component weight without sacrificing structural strength and safety performance, perfectly matching lightweight upgrading trends for new energy vehicles.

Featuring a newly enhanced rigid frame design paired with high-strength alloy tie bars, enlarged thickened anti-wear steel pins and extra-thick high-load platens, the machine delivers greatly improved overall rigidity and ultimate load-bearing capacity at 400 tons of clamping force. The high-stiffness structure minimizes thin-wall mold deformation and molten aluminum splashing during high-pressure forming, ensuring uniform thin-wall thickness and ultra-low internal porosity of on-board charger enclosures. It achieves the ideal balance of lightweight profile and high structural compactness, and supports long-term continuous production of high-standard lightweight new energy power housings with extended equipment service life.

Equipped with an imported German PLC core and full-color HMI touchscreen, the machine supports real-time precise monitoring and dynamic adjustment of injection speed and pressure. Advanced closed-loop control technology enables ultra-fine graded adjustment of the injection process, ensuring fast, uniform filling of large-area thin-wall housing bodies and internal reinforcing rib structures, completely eliminating internal porosity and loose structures. It significantly improves surface flatness and structural rigidity of finished lightweight power distribution housings, reducing subsequent trimming and polishing work. The optimized electrical circuit is simple and stable, adapting to high-temperature industrial production environments, and the intelligent fault display system quickly locates equipment faults to reduce production downtime.

The hydraulic system adopts dual-proportional intelligent control to achieve fast multi-stage thin-wall filling and low-pressure buffered mold clamping, balancing lightweight forming efficiency and mold protection. All hydraulic sealing components are imported from Europe and Japan, with excellent wear resistance, high temperature resistance and leak-proof performance, ensuring long-term stable hydraulic operation under 400-ton clamping force. The hydraulic die height adjustment system enables convenient, efficient mold installation and debugging, saving labor and time costs for lightweight EV power housing mold changeover. The automatic pressure relief energy-saving function reduces system operating load and invalid energy consumption for green, efficient lightweight part production.

The professional clamping and die height adjustment mechanism ensures uniform mold stress and stable positioning accuracy, preventing thin-wall housing deformation and edge warping caused by high-pressure injection. The high-flow valve and precision piston accumulator injection device provides stable, adjustable injection speed and pressure, perfectly adapting to various thin-wall 3-in-1 integrated power unit housing mold designs. The built-in high-efficiency oil cooling system stabilizes hydraulic temperature and ensures consistent lightweight forming quality in long-term production. The equipment has a long service life of 15 to 20 years, and an optional mold sweeping robotic arm is available for automated production upgrade.
