Aluminum Alloy Cold Chamber Die Casting Machine LED Street Light Fixture Housings Machine

Engineered specifically for producing weatherproof IP-rated aluminum alloy LED street lamp enclosures, this 400T cold chamber die casting machine focuses on porosity-free dense forming for outdoor lighting applications. Outdoor LED street lamp enclosures are exposed to rain, dust, ultraviolet radiation and temperature extremes all year round, requiring a fully dense, void-free casting structure to achieve IP65/IP66 waterproof and dustproof performance. This equipment produces high-compactness aluminum alloy lamp housings with excellent sealing surface flatness, effectively preventing water and dust ingress and ensuring long-term reliable operation of street lamps in harsh outdoor environments. It also supports production of related heavy-duty zinc alloy die casting components for outdoor lighting fixtures.

Built with an upgraded reinforced integral frame structure, matched with high-strength tie bars, thickened steel positioning pins and extra-thick load-bearing platens, the machine delivers outstanding overall rigidity and structural stability under 400-ton clamping force. This high-strength structural design provides superior impact resistance and pressure stability during high-pressure die casting, minimizing machine vibration that could cause internal porosity and surface blemishes on lamp enclosure sealing surfaces. The stable forming platform ensures consistent structural density batch after batch, which is critical for achieving uniform waterproof performance and reliable outdoor weather resistance of aluminum alloy street lamp enclosures.

At its control core is a premium German PLC system paired with a full-color human-machine interface touch screen, enabling precise real-time monitoring and adjustable control over injection speed and injection pressure. Advanced closed-loop control technology enables ultra-fine regulation of injection speed throughout the entire filling cycle, effectively eliminating internal gas pores, shrinkage cavities and surface defects on sealing surfaces. This ensures flawless flatness of housing sealing grooves and mounting surfaces, providing a solid foundation for subsequent waterproof assembly and gasket fitting. The optimized electrical circuit structure ensures stable and reliable operation even in high-temperature workshop environments, and the built-in fault display function allows fast troubleshooting and minimal production interruption.

The hydraulic system adopts mature dual-proportional control technology to realize flexible multi-stage injection and gentle low-pressure mold clamping, which protects precision sealing surface mold cavities from impact damage and preserves fine surface texture over extended production runs. All hydraulic seals are sourced from premium European or Japanese brands to ensure long-term reliable, leak-free operation under heavy 400-ton working load. The hydraulic die height adjustment system enables fast, convenient mold setup, and an automatic pressure relief energy-saving function effectively reduces operational energy consumption for mass outdoor lighting production.

The clamping and die height adjustment mechanism ensures uniform stress distribution across the full platen area and stable mold positioning, while the injection unit with high-flow valves and a precision piston accumulator delivers strong, consistent injection performance optimized for dense forming of weatherproof lamp enclosures. A high-efficiency oil cooling system maintains stable hydraulic temperature for consistent process performance, and the machine is engineered for a service life of 15 to 20 years. An optional mold sweeping robotic arm is available for further automation upgrade.
