400T Cold Chamber Die Casting Machine Aluminum Alloy Solar LED Street Light Casing Machine

The machine adopts a newly upgraded fully reinforced frame structure, with high-strength alloy tie bars, enlarged thickened anti-wear steel pins and extra-thick high-load platens, which greatly improves the overall rigidity and ultimate load-bearing capacity of the 400-ton machine. The high-rigidity structural design significantly enhances impact resistance and pressure stability during high-pressure die casting, minimizes mechanical vibration and thin-wall mold deformation during lightweight housing forming. It ensures uniform wall thickness and ultra-low internal porosity of solar street light casings, realizing the perfect combination of lightweight appearance and high structural compactness. The stable mechanical performance supports long-term continuous production of high-standard lightweight lighting housings and extends equipment service life.

Equipped with imported German PLC core and full-color human-machine interaction touch screen, the machine supports real-time precise monitoring and dynamic adjustment of injection speed and pressure. The advanced closed-loop control technology realizes ultra-fine grading adjustment of the injection process, ensuring fast and uniform filling of large-area thin-wall casing cavities, completely eliminating internal porosity and loose structures. It significantly improves surface flatness and structural compactness of finished solar lamp housings, reducing subsequent trimming and polishing workload. 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 realize fast multi-stage thin-wall filling and low-pressure buffer 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 is convenient and efficient for mold installation and debugging, saving labor and time costs for lightweight solar lamp housing mold replacement. The automatic pressure relief energy-saving function reduces system operating load and invalid energy consumption, realizing green and efficient lightweight part production.

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