In order to obtain high productivity and quality control, synchronization of selective Ni plating with machine and assembly process was developed. It is composed of three technical parts.
(1) Synchronizing system of Ni plating at same tact of spark plug manufacturing line.
(2) High speed plating by rotation method.
(3) Selective Ni plating without masking.
This manufacturing system of spark plug has been operated by this new system.
