Process: Molten metal is forced into a steel die using a hydraulic or mechanical press in either a cold chamber (for high-melting-point metals like aluminum) or hot chamber (for lower-melting-point metals like zinc) machine. The metal solidifies rapidly (within seconds), and the part is ejected.
Pressure: High pressure ensures the molten metal fills intricate mold details, resulting in precise, smooth-surfaced parts.
Materials: Aluminum alloys (e.g., ADC12, A380) are common in lighting due to their lightweight, corrosion resistance, and excellent thermal conductivity for heat dissipation.
Equipment: Machines range from 180T to 3000T, depending on part size and complexity.
