Abstract
An improved manufacturing process is provided for surface protective striking tools such as hammers and mallets. An elongate hollow core is fitted with impact heads at opposite ends thereof and filled with a flowable filler material such as small steel pellets prior to placement of the core into a mold cavity for injection mold formation of an outer encasement. During the molding step, the filler material provides a substantially rigid structural backstop which enables a core of lightweight construction to withstand typical injection molding parameters. The molded outer encasement ensheathes a skirt portion of the impact heads and any exposed portion of the core member to bind the impact heads to the core member. The molded outer encasement does not extend over an impact face of each impact head. A handle may also be molded with the outer encasement. A striking tool thus formed is removed from the mold, and some or all of the filler material is drained from the core through an open port. When a handle is provided, a reinforcing rod is inserted centrally within the handle so as to extend the length thereof. The rod may be heated prior to insertion into the handle to help secure the rod in place within the handle.
