When frequency, power and solution are matched correctly to the mold material, ultrasonic cleaning is generally gentler than aggressive manual brushing, which is more likely to cause surface wear over repeated cycles.
Ultrasonic cavitation can reach into fine mold cavities, vents and detail lines to remove built-up release agents, resin residue and microscopic buildup that a brush often cannot fully access.
This depends on production volume, material used and how quickly residue builds up on the specific mold. Facilities running continuous cycles typically clean more frequently than lower-volume operations.
Yes, with the right settings for each material. Hisashi’s mold cleaning range includes machines built specifically for applications like EVA footwear molds as well as general and die-specific mold cleaning.
Cycle time varies with mold size, soil level and material, so it’s best confirmed against your specific molds during a cleaning trial rather than assumed from a general estimate.
