High standard purity specifications with regard to component surfaces made from metal or plastic require optimum processes. In combination with relevant cleaning agents and under consideration of material, component geometry and contaminants, we determine a suitable process to ensure that the necessary cleaning quality is met.

In close collaboration with the client, we are testing out the ideal cleaning process at our technical centre.

For 27 years, we have been cleaning components made from a variety of materials for the automotive industry, OEM’s and their contractors. High standard cleanliness requirements are no foreign terms to us.

Spray cleaning

  • Water-based cleaning agents are systematically sprayed onto the component by means of nozzles.
  • The high kinetic energy of the water jet loosens the dirt.
  • The pressure of the water jet can reach 1 to 60 bar (low pressure cleaning), or 100 to 200 bar (high pressure cleaning/deburring)
  • The geometry of the nozzles has a positive effect on the cleaning performance: impact, jet angle, droplet size
  • The alignment of the nozzles to the component plays an important role
  • Relative motion may be required, depending on the component. This may be needed for e.g. blind holes or undercuts. Either the component or the nozzle is moving in the process.
  • Area of application: suitable for components of all kind

Dip cleaning

  • The workpiece is dipped into a cleaning agent.
  • Contamination, such as oils, greases, metal chips, ... are dissolved by the chemical effect of the cleaning agent.
  • Mechanically induced motions of the component in the dipping bath increase the cleaning effect.
  • Supporting processes: Ultrasound and injection pressure flood cleaning
  • Area of application: Batches, bulk material, individual components, tray goods, etc.

Ultrasound cleaning

  • The workpiece is immersed into a cleaning agent (water + chemical cleaning agent), while ultrasonic waves are delivered by an ultrasonic oscillator
  • In doing so, cavitation is having an effect: Initiated by the ultrasonic waves, steam bubbles are formed on the component surface which collapse again (implode), and thus loosen the dirt in the process.
  • As a result, the cavitation effect depends on the anergy (amplitude), frequency of the ultrasonic waves, and the duration of the ultrasonic process. These parameters are accurately coordinated according to the component concerned.
  • Area of application: Intricate and precision mechanical components with persistent contamination and highest cleaning standard requirements are cleaned here.

Injection flood washing

  • During the injection flood washing process, the workpiece is flooded with the cleaning agent (water + chemical) in a cleaning chamber or bath.
  • At the same time, nozzles randomly add an air flow (pressures of up to 40 bar) into the flooded chamber / container causing strong currents and turbulences within the media.
  • These forces act on the workpiece and thus remove contamination from the component.
  • Area of application: Intricate components with hard to reach areas

High pressure water jet deburring

  • Depending on the component, a water jet with a pressure of up to 2000 bar is applied in either a targeted or random manner.
  • The high kinetic energy of the water jet loosens the burrs adhering to the component in form of removable ridges after processing.
  • Area of application: Clearing of removable burrs
  • Deburring of areas where other processes encounter technical or economic limitations.

Combination of cleaning + deburring

  • High pressure water jet deburring and cleaning can also be performed in a single process.
  • The high kinetic energy of the water jet loosens the burrs adhering to the component in form of removable ridges after processing.
  • Furthermore, persistent contamination is removed with the use of appropriate cleaning agents and lower pressures, if necessary.
  • Area of application: Components for diesel injector systems, cylinder heads, pump bodies, die cast aluminium components, ...

Preservation (Protection treatment)

The preservative is applied to the component during the dipping or spraying process to avoid rust formation.

Depending on the preservative and process used, rust protection can be guaranteed for up to 2 years.

Components: diverse components made from steel or cast iron.
