Pre-treatment and painting systems

Lechler nozzles are an integral part in pre-treatment and painting systems

pre-treatment and painting systemsIn pretreatment and painting systems, water jet cleaning is often employed as an automated process.For this application, Lechler supplies many different nozzles and installation possibilities (see MEMOSPRAY, EasyClip and couplings, spacers and end caps for pipe installation).At the end of a painting line, the components pass through a rinsing zone.

Nozzles for water jet cleaning

  • Use of flat spray nozzles and tongue-type nozzles with eyelet clamps for automated spray jet cleaning.
  • Components are treated in different process steps with different liquids (e.g. aqueous / alkaline solutions, deionised water).
  • Eductor nozzles are also used under water, the purpose of which is to prevent sedimentation.

Nozzles and installation possibilities of pre-treatment

  • Different nozzles available, e.g. MEMOSPRAY or EasyClip.
  • Many different possibilities for pipe mounting such as couplings, spacers or end caps are available.

Nozzles for the rinsing zone

  • Nozzles are used at the end of the painting line to wash off surplus paint particles mechanically
  • This is done according to the cascade principle, i.e. in several stages with increasingly clean rinsing agent until deionised water is used.
