Abstract
The spark plug is of a type in which the assembly of metal body (20) and ceramic insulation (10) is achieved by means of rimming the body. According to the invention, the finished body of the spark plug, including collar (24) of reduced thickness (s) is obtained by a pressing operation. Application : spark plugs for internal combustion engines, especially for motor vehicle engines. Advantages : the stamped body provided with a collar does not require any successive turning operation, hence production costs are reduced due to savings in labor and material.
