Mold Cleaning: Clean Injection Molds without Damage and with Aqueous Chemistry

The use of ultrasonic cleaning equipment for routine injection mod maintenance has been effectively employed for many years. It provides a number of benefits not achievable using more traditional methods. As a non-contact method, mold detail is not damaged during cleaning and critical tolerances can be maintained, extending mold life. The higher levels of cleanliness attained using ultrasonic cleaning also results in better releases and longer runs while improving productivity and minimizing scrap. The penetrating nature of ultrasonic cleaning removes residual polymer and releases from mechanically active mold components extending their life and can also remove buildups from internal cooling ports and channels, thereby improving polymer flows. Ultrasonic cleaning depends upon cavitation, the rapid formation and violent collapse of minute bubbles or cavities in a cleaning liquid. This activity, when combined with an appropriate cleaning chemistry, creates a unique penetrating action that is highly effective, even in blind holes and tiny crevices. This combination of high energy, deep penetrating, and non-contact gets results. No other process cleans faster, more safely, or more thoroughly.
