CORONA TREATMENT OF LENSES:

                                            

                                

Ophthalmic plastic lenses are sophisticated products, and their performance relies very much on the corona surface treatments they are undergoing in the manufacturing process prior to applying i.e., tinted, photo-chromic or hard coatings. Dyne Technology Ltd offers the Tantec developed Corona treatment system to improve quality and productivity of optical lens manufacturing. The new in-line Corona treating units are now making the labour intensive batch pre-treatment very ineffective. The Corona treatment system called "RotoTEC" uses an in-line "o-ring type" belt conveyor with an integrated rotary electrode system to ensure an extreme uniform Corona discharge distribution on the optical surfaces. Surface tensions as high as water wettability (72 mN/m) are achieved, which makes a RotoTEC unit indispensable prior to the lens washing station. As the water spreads evenly on the surface, an ultra-clean surface is presented to the following coating processes. After washing and drying, the Corona treatment effect is more or less gone, therefore the lenses are passing through a second RotoTEC corona treatment unit on the line to re-establish high surface tension before the first coating process. A third RotoTEC corona treating unit is required downstream if a further layer of coating is prescribed e.g. photochromic or hard coatings.

Dyne Technology can supply the Tantec RotoTEC corona treating unit as either a single or double lane  conveyor with an open front design for easy access and quick belt exchange. All belts are changed in around 3 minutes without disassembling any machine parts.
