Difference between Sandblasting and Ultrasonic Cleaning Moulds

Sandblasting is slow, labour intensive and destructive to the mould surface, compared to ultrasonic cleaning which is reliable, labour cost saving and the combination of chemical and mechanical cleaning produces a much superior clean.

Ultrasonic cleaning removes stubborn contamination from mould parts made of cast iron, bronze and stainless steel. It cleans e.g. cavities, cooling channels, vacuum channels and pin vents on mould halves, bottom plates, baffles, plungers, neck rings and guider rings. Ultrasonic cleaning methods are applicable also for maintenance cleaning of the forming machine parts.
