Die Casting Aluminum Front Lamp Heat Sink Base Machine 280T Cold Chamber Diecast Machine

Tailored for manufacturers producing intricate lamp heat sink bases with fine, dense cooling fin structures, this 280-ton cold chamber die casting machine is engineered to extend mold service life and boost production yield, directly lowering tooling and rework costs for automotive headlight, motorcycle spotlight and rear lamp heat sink production.

The machine is built on a reinforced, stress-relieved frame with high-strength tie bars and thickened platens, delivering exceptional rigidity and stable clamping performance. It is controlled by a premium German PLC system with a full-color touch screen, which allows operators to set, monitor and save precise injection speed and pressure profiles for every lamp heat sink model. Closed-loop control technology delivers fine, real-time adjustment of injection velocity, ensuring complete filling of thin fin structures while reducing internal porosity, which cuts down defect rates and improves first-pass yield.

Its hydraulic system adopts dual-proportional control to enable programmable multi-stage injection and gentle low-pressure mold clamping. This soft clamping approach effectively protects delicate fin cores, thin mold inserts and precision cavity surfaces from impact damage during mold closing, significantly reducing mold repair frequency and extending tool life for lamp heat sink production. All hydraulic seals are sourced from top European or Japanese brands, delivering reliable, leak-free performance and minimal maintenance needs over long-term operation.

The clamping unit with integrated die height adjustment distributes clamping stress evenly across the entire platen, eliminating uneven flash and maintaining accurate mold alignment throughout production runs. The injection system, equipped with high-flow valves and a precision piston accumulator, delivers consistent, repeatable shot performance and works seamlessly with various lamp heat sink mold designs, from single-cavity headlight bases to multi-cavity spotlight housings. The high-efficiency oil cooling system keeps hydraulic temperature stable, supporting a 15–20 year service life even under heavy production loads. An optional mold sweeping robotic arm is available for further automation.
