Abstract
Metal sleeves are used as carriers for the abrasive layer of sawing beads. Such sawing beads are threaded on a steel cord and are separated by a polymer thus forming a sawing cord for sawing of hard and brittle materials such as stone or concrete. These metal sleeves have a large influence on the overall performance as well as on the cost of the sawing cord. The inventors propose the method of metal injection molding to make the metal sleeves in large quantities with an optimized geometry which is not possible with the current methods for making the metal sleeves. Over and above the inventive sleeves are particularly well suited for application of the abrasive layer by means of laser cladding. Beads made by laser cladding on the inventive metal sleeves as well as sawing cords comprising such beads are therefore part of the invention.
