Oil management

In 70 to 90 % of cases, damage to hydraulic components is attributable to impurities in the hydraulic system. Through oil management, you can prevent contamination of this kind and permanently improve the availability and reliability of your ALLROUNDER injection moulding machines.

Oil management is not restricted to you as the end user – it already begins from when an injection moulding machine is built. By consistently cleaning and protecting components, we prevent initial contamination of the hydraulic circuit. Moreover, we also commission all new injection moulding machines before they leave our parent factory. The purity class of the oil used is continuously monitored and the oil tank is cleaned out before and after the in-house tests.

What you should do

  • Use oil management to prevent contamination
  • Only use hydraulic oils of the required purity class 18 / 15 / 12 (ISO 4406) or higher
  • Avoid conventional oil from the barrel – it does not conform to the required purity class and results in contamination of the hydraulic system
  • Store hydraulic oils correctly and filter them before use
  • Use micro-filter units for filling and topping up hydraulic oil
  • After filling and topping up: Allow the oil to degasify for at least one hour before first switching on the pump, and bleed the hydraulic system thoroughly by means of slow machine movements
  • Regularly analyse hydraulic oil for contamination – a laboratory report allows you to draw conclusions about possible wear, e.g. to pumps and seals
  • If necessary, clean the hydraulic oil using micro-filter units in the bypass
  • Observe the oil change intervals
