Method for making phase change material products and system therefor

A method for processing phase change material includes providing pieces of phase change material having a transition temperature, the pieces of phase change material being in a solid phase. A medium is provided which is transformable from a liquid state to a solid state, the medium is in the liquid state and at a temperature which is below the transition temperature of the pieces of phase change material. The pieces of phase change material are combined with the medium to form a mixture. The mixture is supplied to a tool which forms a phase change material product. The medium is then transformed to the solid state.
