1. A method of manufacturing base plates for miniature hard disc drives comprising:
- a) providing a metal strip to be formed into a plurality of base plates; and
b) feeding the metal strip continuously through an injection molding machine to sequentially injection mold a monolithic body layer of phase change material on one or more surfaces of the metal strip to form said plurality of base plates for miniature hard disc drives, wherein said monolithic body forms body features on each base plate.
