Cast aluminum light parts, such as light cover, are an electrical housing used to protect the internal light-emitting unit and other electronic components from damage by external harmful elements. In addition, cast aluminum lamp housings share common protection requirements with electrical housings. However, in addition to the above functions, light cover should also have an aesthetic appearance, which is slightly different from electrical housings. In short, the design of lamp parts such as lamp housings should meet the practicality of electrical housings and also consider the aesthetics of lamps. All of this requires lamp designers to have rich experience and also requires strong support from professional lamp parts manufacturers. GLL is a leading aluminum foundry based in China, dedicated to offering seamless support from the initial design phase to the final production of lamp components. What is Aluminum Die Casting? Aluminum die casting is a production technique where molten aluminum is forced into a mold under high pressure. This process enables the creation of intricate and detailed shapes with exceptional precision, making it perfect for industries that demand high-quality, cost-efficient components. The outcome is a lightweight yet durable product with excellent thermal conductivity, corrosion resistance, and structural integrity. Why are LED housings created with die casting? Most LED housings are produced through the aluminium die casting process for a multitude of reasons:
- Excellent surface finish – LED housings require a smooth surface for aesthetic purposes, and aluminium die casting provides just that. Thanks to this, manufacturing costs are reduced, as no further polishing or machining is needed to smoothen the metal parts.
- Complex shapes – With aluminium die casting moulds, 3D LED housings can be as intricate and complex as necessary to meet various needs, whether you’re looking to create wiring channels or heat sinks.
- Dimensional accuracy – LED housings produced by aluminium die casting are uniform and offer nearly unrivalled levels of dimensional precision, making them suitable for assembly with other components in LED systems.
- Cost-effectiveness – Producing a high volume of LED housings using aluminium die casting is highly cost-effective as thousands of metal components are manufactured rapidly, ultimately reducing production costs.
