Cold Forging Heat Sink 

Cold forging is a technique for the material forming at a temperature that is lower than the material's recrystallization temperature (typically means room temperature). Typically used cold forging materials include aluminum and its alloys, copper and its alloys which have a smaller resistance to deformation under room temperature and have higher plasticity. During the forming process, cold forging allows work hardening (strain hardening) so that both the strength and hardness are enhanced. The cold forging technique has been widely used by heat sink manufacturers in the production of light source heat sinks and LED heat sinks.

Cold forging material is mostly below room temperature deformation resistance is lesser, plasticity better aluminum and partial alloy, copper and partial alloy, cold forging can make profile produces work hardening in processing process (strain hardening), can make intensity and hardness increase.

Cold forging heat sinks have better mechanical performance, higher throughput and higher material utilization rate. Therefore, it is especially suitable for large batch productions in order to reduce production costs.

1. Feature: the process of cold forging is forging the raw material without heating it up and shape will be formed by tooling. The shapeable and softer material is suitable for cold forging, which like aluminum, copper, copper alloy, etc.

2. Advantage:

1). Surface quality is better, accurate dimension; 

2). Cold forging can reinforce the strength of the material; 

3). The production process is efficient, suitable for high-value products, and low unit cost.

3. Capability: Max. product size: W250 * L250 * H150 mm.
