Lori is a professional supplier of LED cooling solutions and LED heat sink manufacturers. LED light heat sink are various, the common types are aluminum extruded heat sinkLED sunflower heat sink, die-casting heatsink, stamping heatsink,cold forged heat sink,skived heatsink and so on. LORI has rich experience in high-power LED heat dissipation. Currently, Lori has provided LED cooling solutions for LED street lamps, greenhouse vegetable LED lights, LED projection lights, car lights, tunnel lights, solar street lamps and so on. Lori led heat sink types as following:

LED heat sink options:


Extruded aluminum heat sink: This LED heat sink is formed by aluminum extrusion, and by CNC machining, embedded in heat pipe, and finally finished by surface treatment. Led extruded aluminum heat sink is liquid aluminium formed through a fixed mold. Then cut the led heat sink aluminum profile and mchined into the desired shape. The post-processing cost is high, and the fin can be made very thin to increase the heat dissipation area. When the heat sink works, air convection diffusion heat automatically formed, and the heat dissipation effect is good. Common materials used in aluminum extrusion are AL6063 and AL6061.


Die cast aluminum heat sink: Die casting part is a kind of pressure casting parts, it is to use the die casting machine, which installed pressure casting mold , the heating for liquid copper, zinc, aluminum or aluminum alloy into the mouth poured into the die casting machine, die casting machine die casting, casting the shape and size of aluminum or aluminum alloy parts, such parts are usually called aluminum die casting. Die-cast aluminum heat sink are generally large in size, with irregular design and controllable production cost. The heatsinks cannot be made very thin, so it is difficult to maximize the heat dissipation area.The commonly used die casting materials for the LED heat sink  are ADC10 and ADC12.


Stamping heat sink: Stamping heatsink is a forming and processing method that relies on press and mold to exert external force on plate, strip, pipe and profile to produce elastic deformation, plastic deformation or separation, so as to obtain the required shape and size of the stamping heatsink .Stamping and forging belong to the same plastic processing (or pressure processing), collectively known as forging. Stamping materials are mainly hot and cold rolled steel and steel strip. Compared with die casting heat sink and forging heat sink, stamping heatsinks are thin, even, light and strong. The quality of stamping heatsinks is very small, the material utilization rate is high and the production efficiency is high.


Cold forged heat sink: Cold forged heat sink is made by steel, aluminum alloy sheet stamping, pull to rise, make a cup of tube type of heat sink, cold forged heat sink inside and outside perimeter smooth, LED cold forged heat sink commonly used aluminum alloy material is AL5052, AL6061, AL6063, the quality of cold forged heat sink is small, high material utilization, high production efficiency, is a low cost solution. This process is mainly used in the manufacture of LED light heat sink.
