To Provide High Quality Die Casting Services For All Industries


The aluminum housing of die-cast LED lighting is generally made of zinc-aluminum alloys by die-casting, and its conductivity is about 80-90W/MK. Many 1-3W low-power spotlights basically use this technology. Its advantages are low production costs and fast production speed.

The aluminum cast lighting parts have the advantages of excellent heat dissipation, long life, low power consumption, more energy-saving and environmental protection, which have uniform lighting effect, flexible connection, flexible use, good waterproofness, and adapts to various occasions.

  1. Good product quality: castings have high dimensional accuracy, generally equivalent to 6~7, or even up to 4; good surface finish, generally equivalent to 5~8; strength and hardness are higher, and the strength is generally 25 higher than sand casting ~30%, but the elongation is reduced by about 70%; the size is stable, and the interchangeability is good; it can die-cast aluminum thin-walled complex castings. For example, the current minimum wall thickness of zinc alloy die-cast aluminum parts can reach 0.3mm; aluminum alloy castings can reach 0.5mm; the minimum casting aperture is 0.7mm; the minimum pitch is 0.75mm.

  2. High production efficiency: high machine productivity, for example, the domestic J Ⅲ 3 horizontal cold air die-casting aluminum machine can die 600-700 times of aluminum in eight hours, and the small hot chamber aluminum die casting machine can die aluminum 3000-7000 times every eight hours.

  3. Long life of die-cast aluminum lighting.

  4. Die-cast aluminum lamp body, simple and elegant appearance, easy to use; The projection angle can be adjusted according to the needs; The integration of lamps and lanterns, the shape is light and beautiful, and the installation is simple; The front opening type replaces the light source, easy to maintain; Dustproof and waterproof.

  5. Applications: cast landscape lighting, cast aluminum outdoor wall light, etc.
