Ultrasonic cleaning of glasses frames, optical lenses and components
With regard to optics, in general, and eyeglasses, in particular, ultrasonic cleaning systems have been used widely across the sector, for a number of years.
Each part of metal or acetate frames, following the final phase of polishing with abrasives, must be thoroughly degreased.
The effect of ultrasonic cleaning, in combination with an appropriate water-based detergent, removes all contaminants from the innermost areas which are inaccessible with manual methods, without scratching or, in any way, damaging the surface.
Specifically, the following are the subject of ultrasonic cleaning:
- optical frames after polishing with paste
- optical frames in preparation for powder coating or electrodeposition
- optical lenses before PVD, vacuum treatments
- lenses after processes using oxides, pitch and bonding agents
- rods, fasteners and hinges
Italy is a leading manufacturer in cleaning systems for eyeglasses, optical lenses and related.
For over 50 years, MORONI ULTRASONICS has manufactured ultrasonic cleaning systems, as part of its key role in support of this industry.
Both large and small companies in the sector have adopted our cleaning systems, from the single tank SONOX range to more complex automatic systems in preparation for various processes: powder coating, galvanic, metalisation, engraving, etc.
Major manufacturers in the sector of finishing and cleaning eyewear and related products use our components (generators and transducers) to equip their ultrasonic cleaning tanks.
We supply complete turnkey systems for cleaning eyewear with polishing paste, the preparation of lenses, vacuum metalisation, degreasing metal and plastic frames prior to powder coating.
Cleaning eyewear with water-based detergents
An important step, promoted by MORONI ULTRASONICS, was when it became time to eliminate cleaning systems which used fluorinated solvents (FREON and similar agents) in the processes used to manufacture eyewear. This is due to the known problem of the hole in the ozone layer.
Fluorinated solvents were widely used in the closed distillation cycle, even by us, to clean polishing pastes from frames for eyeglasses.
In a short period of time, we had to develop cleaning cycles which used water-based detergents, followed by appropriate rinses in water which was more or less treated (distilled, demineralised, etc.), and hot air drying systems.
Today, fluorinated solvent systems no longer exist and all cleaning system manufacturers use water exclusively for all their procedures.
