Ultrasonic cleaning

Product applications

Ultrasonic cleaning

High-grade cleaning plays an important role in the care and maintenance of tool moulds, which are typically used for rubber and plastic formed part production. A wide variety of different processes are available for cleaning the parts. Cleaning systems utilising only chemicals frequently do not have a thorough enough effect and require large volumes of cleaning agents. This increases the operating costs and harms the environment. Ultrasonic cleaning systems achieve significantly better cleaning results while using less chemicals.
