The dimensions of cold forging heat sink, 1. Outside Diameter: as your request 2. Total Height: as your request 3. Base Thickness: as your request 4. Pin Height: as your request 5. Color: silver, gold, black, red, as your request GLARY has an extensive range of options to provide the optimal cooling solution for your LED application. Our precision forge process provides unique advantages for LED cooling. Forging can produce round and other non-linear shapes that are preferred for LED applications. The forge process uses high pressure to form the material and provides control over the grain structure to provide superior thermal performance. LED`s are generally convection cooled and our forged pin fin arrays provide the best possible thermal performance in ambient environments. Heat sinks can be forged in either aluminum or copper. Sizes range from 40 mm diameter to 350mm and shapes can be almost any shape you need. Standard or modified standard solutions We can provide a solution from our standard product line and model it to ensure that it will provide adequate cooling for your application. Custom design services Our engineers can also work with you to design and model a custom solution optimized to meet the needs of your application. Note: All machined parts are just for your reference, machined parts can not be provided to you, but the original design can be provided. The machined part is belong to the customer who provide the original machined design.
