" Amulaire's highly flexible metal injection molding processes enable the company to make cold plates with features such as the following:

- - Fins that go in multiple directions on a single cold plate

- - Fins at any angle, curved or in any pattern required

- - More pin fins (to increase the surface area of the cold plate and enhance thermal performance)

- - Microchannels -- with fins as small as 0.15mm wide and 0.7mm high, with 0.15mm spacing -- for very precise liquid cooling solutions"
