Low cost targets and practical manufacturing techniques have historically limited heat sink designs. With metal injection molding, engineers can creatively optimize the shape and form of the heatsink to maximize performance without cost consequences. The improved thermal performance is critical with compact, high power devices.

The MIM process allows thin walled heat sinks to be injection molded to maximize surface area in a compact package. Walls can be a thin as 0.3 mm with similar inter-spacing.

This particular design employs a wave pattern which would be impossible to extrude and cost prohibitive to machine. It is an excellent example of the design freedom offered with metal injection molding.
