Abstract

Low voltage varistors having one or more recesses or dimples which reduces the thickness of the varistor in the recessed areas are provided by an improved process which comprises fitting a pressing surface on a die punch with a resilient material, preferably an abhesive material such as polydimethylsiloxane, having one or more nipples whereby during pressing of a metal oxide varistor powder contained in the die cavity the nipple imparts a depression thereby reducing the thickness of the varistor body in said depression. In addition, the resilient material aids in the distribution of the powder during pressing and with the preferred abhesive material aids also in the release of the pressed body from the die.
