Abstract
A method of forming an computer component having improved damping capability is described. The method comprises providing a die for forming an computer component, inserting a water soluble salt block having a desired hollowing form into the die, and injecting formable material such as die-castable or thixoformable material in fluid form into the die such that the fluid forms around the salt block and substantially covers the salt block. Once the formable material solidifies to form the computer component, the solid computer component is subjected to pressurized steam to dissolve the salt within the solid component, thus leaving a hollow core of the desired hollowing form. The salt block can have at least one which forms an outlet opening in the solid computer component. The computer component can be, for example, an computer arm or an E-block for a computer hard drive.
