History : innovation and technology

The Beginnings

The company was established in 1949 in Courbevoie, to the West of Paris, manufacturing electric component, plugs, switches, fuses. They built workshops and equipped them with a modern production tool, in particular with a gas oven of 1600°c.

Very quickly, the use of porcelain was overtaken by a new insulating material for electro-technical applications: steatite (chemical name of talc). The qualities of this insulating ceramic led to an increase in demand, which proved difficult to meet.


To differentiate itself from the competition, the company moved the production from semi-finished ceramic components, to completely finished products: fully assembled metal electrodes, incorporating the ceramic component. Presently, our company specializes in the production of finished products “electrode”, intended for the market with manufacturers of boilers and ovens, both industrial and domestic. From this period on the company has therefore targeted major OEM accounts both in France and abroad.

Always in search of an improvement of its products, the company made a major advance – it perfected the processes allowing it to enter the market of ceramics using alumina, (also used for spark plugs in the car industry), of high quality and superior performance. This required however substantial investment, mainly the production of small ignitors for gas stoves and wall water heaters. Since by this time production volumes had increased substantially, the company so moved in 1970 to a new building at site to the of south of the Paris conurbation, called Coudray-Montceaux

As the market advanced to condensing boilers and sealed combustion, Sapco decided to concentrate on a particular market niche: the manufacture of electrodes for condensing boilers, as opposed to atmospheric boilers, as our technology is a best fit for this application .

Noting that the customers have to deal with specific problems such as the electrical arcing, or the Corona effect, the company also developed special connectors and cables to solve these problems and so was able to offer a complete product range for its customers.
