Ultrasonic Cleaning Molds
Maintenance and Refurbishment of Molds
Moroni offers systems for ultrasonic mold washing as a viable alternative to other types of treatments such as abrasive sandblasting, cryogenic sandblasting, bead blasting, or immersion/spraying with acidic liquids. This process is less aggressive, especially for delicate parts such as edges, surfaces, or mating surfaces.
Our extensive experience in the field enables us to design washing systems for mold cleaning during maintenance and refurbishment, which can be applied across various industries. These systems find applications in sectors such as rubber, plastic, and aluminum production, the food industry, die casting, sheet metal shredding, and the agri-food industry.
For mold washing, we utilize LIFTER systems, which are suitable for cleaning molds as well as heavy marine engine components weighing over 1,000 kg.
Another example of washing in heavy mechanics: washing molds
The molds are loaded onto a platform. At START command, automatic:
- the platform goes down,
- the cover closes,
- the ultrasound lights
- starts a “up and down” movement (tilting) at the end of which
- opens the lid and the platform is in the loading / unloading position
Cleaning the melds with ultrasounds has significant advantages over other systems (sandblasting and pallinating, high pressure water jet, nitrogen or other):
- Uniform treatment without abrasion of edges and surfaces
- access to the most hidden and unreachable points
- Use of normal alkaline detergents against the use of acids
- zero labour
After washing ultrasonic molds generally no other treatments such as rinses, protection or drying are required. For washing purposes, Moroni Ultrasuoni employs a low-concentration alkaline aqueous detergent, which often eliminates the need for rinsing or protecting the metal. Additionally, the hot parts typically dry autonomously within a few minutes.
In other cases, mild washing often requires a complex treatment sequence, for example:
- prewash
- ultrasound
- rinse
- protection
- drying
This is all automated due to the heaviness of the baskets loaded with the melds.
