The conventional mechanical and manual method of cleaning of moulds and extrusion tools is slow and labour-intensive. At worst, it can also be abrasive and destructive to the mould surface. Ultrasonic mould cleaning is based on combination of chemical and mechanical cleaning and it is thus able to remove both dry and wet contamination. Ultrasonic cavitation removes stubborn contamination from metallic surfaces, yet is gentle and non-abrasive on the base material even as the mould goes through a countless number of cleaning cycles. Users of ultrasonic cleaning have typically reported 40-50% cost savings in mould maintenance compared to traditional methods.
