This 400T multi-functional cold chamber die casting machine is designed for flexible customized production of complex-structured aluminum alloy LED road lighting housings, covering special-shaped street lamp bodies, integrated mounting structure housings, modular lighting fixtures and non-standard customized lamp shells. Standard die casting equipment has poor adaptability to complex and irregular lighting housing structures, prone to incomplete filling and deformation. This 400-ton machine features flexible parameter adjustment and strong mold compatibility, meeting personalized customized production needs of various special and complex LED street light housings. It also supports customized production of related zinc alloy die casting parts for special lighting applications.

The machine is built with a reinforced rigid frame structure, matched with high-strength tie bars, enlarged positioning steel pins and extra-thick machine platens, with greatly improved overall rigidity, shock resistance, and load-bearing performance for 400-ton clamping force. The stable mechanical structure ensures no vibration or displacement during high-pressure die casting, maintaining consistent forming quality whether producing large flat lamp housings or special-shaped curved lighting bodies. It has strong adaptability to medium and large-sized aluminum alloy lighting products with different structures and fine details, and can stably support long-term flexible switching production of customized lighting parts.

Adopting German PLC intelligent control system and high-definition color human-machine interface, the machine supports one-click storage and quick switching of multiple sets of production parameters. Operators can flexibly adjust injection speed and pressure according to different complex street light housing mold characteristics, realizing targeted precision forming for customized products. The closed-loop speed regulation technology ensures stable and accurate injection parameters, avoiding quality fluctuation caused by frequent model switching. The simplified electrical system runs stably in high-temperature environments, and the real-time fault display function ensures rapid fault diagnosis and efficient production recovery.

The dual-proportional hydraulic system has powerful compatibility, supporting multi-stage thin-wall precise injection for decorative lamp housings and high-pressure dense filling for structural lamp bodies, as well as low-pressure protective mold clamping of precision customized molds. Equipped with high-quality European and Japanese oil seals, the hydraulic system operates stably and leak-free for a long time under 400-ton working pressure. The flexible hydraulic die height adjustment system greatly shortens mold replacement and debugging time, improving the efficiency of multi-style lighting housing switching production. The automatic pressure relief energy-saving system intelligently reduces energy consumption during standby and operation, reducing production costs for customized multi-variety processing.

The uniform-stress clamping device and precise die height adjustment system ensure stable mold positioning and uniform force, adapting to various special-shaped and conventional street light housing molds. The injection unit composed of high-flow valves and precision piston accumulators provides accurate and adjustable injection volume and pressure, meeting the forming requirements of diversified customized aluminum alloy lighting housings. Equipped with an efficient oil cooling system, the equipment operates stably for a long time with a service life of 15–20 years. An optional mold sweeping robotic arm can be configured to improve production flexibility and automation level.
