Abstract
A method for fabricating a disc drive load/unload ramp incorporates a disc drive compatible lubricant as the mold releasing agent. A mold having a load/unload ramp cavity is sprayed with a predetermined amount of disc drive compatible lubricant so that the finished load/unload ramp exhibits a predetermined thickness of lubricant. Alternatively, a known amount of disc drive compatible lubricant is combined with the load/unload ramp polymer during the melting stage of the molding process to yield a load/unload ramp exhibiting a predetermined thickness of lubricant. In either case, the lubrication of the load/unload ramp is integrated into the fabrication process in order to obtain a one step finished pre-lubricated product.
Claims7
A method of fabricating a load/unload ramp for a disc drive, the method comprising:
- (a) providing a load/unload ramp composition comprising a polymer and a lubricant selected from perfluororpolyether and derivatives thereof;
- and
- (b) injecting the composition into a mold to form a load/unload ramp, wherein the amount of lubricant in the composition is sufficient to provide a layer of lubricant on a surface of the ramp with a thickness of between about 200 Å and about 500 Å.
