280T Cold Chamber Diecast Machine Aluminum LED Lamp Shell Die Casting Machine

Engineered specifically for high-power LED lamp heat sink bases that demand exceptional thermal conductivity and low internal porosity, this 280-ton cold chamber die casting machine produces high-density, porosity-minimized aluminum alloy castings that deliver consistent, reliable heat dissipation performance for high-output automotive and motorcycle lighting systems.

It is equipped with a premium German PLC control system and high-resolution color touch screen, enabling precise, real-time monitoring and adjustment of injection speed and pressure profiles. Advanced closed-loop control technology enables fine-tuned multi-stage injection filling, which effectively reduces gas entrapment and internal porosity, resulting in heat sink bases with uniform internal density and uncompromised thermal conductivity — critical for high-power LED headlights and spotlights that generate significant heat.

The dual-proportional hydraulic system delivers fully programmable multi-stage injection and low-pressure mold clamping, and is fitted with top-grade European or Japanese oil seals for long-term, leak-free reliability. The clamping and die height adjustment unit guarantees even stress distribution and highly accurate mold positioning, while the injection system with high-flow valves and precision piston accumulator delivers fast, stable filling performance that fully forms dense fin structures without cold shuts or porosity defects.

Built with a heavy-duty rigid frame and an efficient oil cooling system to maintain stable process temperatures, the machine delivers consistent high-density casting performance over a 15–20 year service life. A mold sweeping robotic arm is available as an optional upgrade for automated production.

Delivery is completed within 20 days of order confirmation. We offer 2-hour rapid technical response and 24-hour on-site after-sales service, dedicated one-on-one technical support, on-site commissioning by certified process engineers, full technical support for high-density casting process optimization, and we welcome all customers to visit our factory for live casting demonstrations and technical exchange.
