The use of ultrasonic cleaning equipment for routine mold maintenance has been effectively employed for many years. It provides a number of benefits which may not be achievable using traditional methods. As a non-contact method, mold core / cavity 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 polymers and releases from mechanically active mold components extending their life and can also remove buildups from internal ports and channels, thereby improving polymer flow.
AWhile the chemistry can vary based on the mold material or the type of soil, most molds are cleaned in a buffered alkaline solution. These materials are widely available and very cost effective to use. To help with chemistry and process development, SIBAS maintains a free application evaluation services. Parts submitted to the application laboratory will be cleaned and returned with recommended chemistry, process and equipment to meet your operational needs.
