Housings for glow plugs for diesel engines

  • High volumes – multi-spindle machines
  • 100% control
  • Surface treatment
  • Gun drilling up to 30xD
  • Tangential thread rolling
  • Drilling of holes (tolerances 18µm, Rz8)

A family of housings is produced in different dimensions, but they are all surface treated in barrels. After the surface treatment, a 100% control is performed, and when needed also thread rolling.

Slovenian technical wisdom: a smart glow plug, developed by our valued partner Hidria. A new generation of diesel engines with lower fuel consumption and cleaner exhaust:

  • System for cold starting of diesel engines and powerful sensors for monitoring engine operation
  • Spark plug reduces emissions of nitrogen oxides
  • Housing as an integral part of a smart glow plug
