400T Cold Chamber Die Casting Machine Aluminum LED Heat Sink Housing Die Casting

Optimized for high-volume mass production of aluminum alloy LED street light fixture housings for municipal engineering and road lighting projects, this 400T cold chamber die casting machine supports large multi-cavity mold setups to deliver outstanding production efficiency and exceptional batch-to-batch consistency. Municipal street lighting projects demand large supply volume, stable dimensional uniformity and low defective rate. This 400-ton equipment solves the key points of low single-cavity output and unstable quality in traditional production, making it the ideal core equipment for large lighting hardware manufacturers fulfilling bulk municipal orders. It is also compatible with related large-sized zinc alloy die casting parts for lighting and construction applications.

Its newly reinforced heavy-duty frame structure, combined with high-strength tie bars, enlarged steel pins and extra-thick platens, significantly enhances overall machine rigidity and load-bearing performance to support 400-ton clamping force. This heavy-duty construction delivers superior impact resistance and load stability under high-pressure casting conditions, minimizing mechanical deformation over long continuous production runs. For mass-produced street light housings, this translates to consistent filling across all mold cavities, controlled flash and stable dimensional accuracy across every production batch, which directly reduces sorting, deburring and secondary machining costs downstream.

Control is managed by a German PLC system with an intuitive color touch screen HMI that provides complete digital oversight of injection speed, pressure and all critical process variables. Production parameters can be saved in reusable recipes and recalled with one click, ensuring consistent process performance shift after shift and excellent uniformity for bulk street light housing orders. The simplified electrical circuit design ensures stable and reliable operation even in high-temperature workshop environments, and the built-in fault display function enables quick diagnosis of electrical issues, minimizing unplanned downtime. Closed-loop control technology delivers precise injection speed regulation, ensuring even filling across every cavity in multi-cavity lamp housing molds and eliminating incomplete fill or weight variation defects.

The dual-proportional hydraulic system enables smooth multi-stage injection filling and gentle low-pressure mold clamping, and is fitted exclusively with high-quality European or Japanese oil seals for dependable, leak-free operation during long continuous production runs. The hydraulic die height adjustment system enables fast, convenient mold setup and changeover, reducing downtime between different street light model runs. An integrated automatic pressure relief energy-saving system effectively reduces operational energy consumption and lowers per-unit production costs for mass-produced aluminum alloy lighting housings.

The clamping unit with precision die height adjustment guarantees uniform clamping stress across the large 400-ton platen and highly accurate mold positioning, while the injection system with high-flow valves and a precision piston accumulator delivers consistent shot volume and velocity for various sizes of multi-cavity street light housing molds. Built with a rugged, stress-relieved machine body and an efficient oil cooling system, the machine is engineered for a service life of 15 to 20 years under continuous multi-shift production. An optional mold sweeping robotic arm is available for further efficiency improvement.
