Mask Cleaning Unit

Easy to operate

The TES mask-cleaning unit is unique in the CD industry. The unit offers easy operation, is simply to keep clean and all proceedings with masks do remain on one spot. The cassettes for the masks in the caustic soda bath can be manufactured to the requirements of the customer. The chance of mask damages from this cassette is minimal because it is made of Polypropylene. The acid is kept on a fixed temperature (50 degrees Celsius adjustable). The evaporated water will be supplied by an automatic filling device together with a level regulator (only on the acid bath).

Safety

The unit is equipped with high side-panels around the baths to keep splashes inside. Filling of the baths takes place at the bottom of the bath to prevent unnecessary splashing. As a standard the unit is equipped with an exhaust-pipe for the gasses on both the caustic soda and the acid bath. The covers can optionally be equipped with switches to actuate a two speed extractor (cover closed, fan low, cover open, fan high). An eye shower is standard.

Compact design, yet easy access to all components.

Construction

The unit is completely made of Polypropylene, the legs and the frame are reinforced with steel profiles.

Operation

The masks to be processed are placed into the left bath with the caustic soda. After a few hours when the aluminium has come off, the mask can be taken out of the bath and rinsed with the hand shower. After this the mask is put into the acid bath for 1 or 2 minutes in order to remove stains. When the mask is rinsed and dried it is ready for use. We recommend to sandblast the mask every fourth time to maintain aluminium adhesive properties of the mask. The operator can wash his hands at the right hand side of the unit, the eye shower is positioned on the tap.

Filling the baths

The caustic soda bath is filled with a hand operated water valve. The filling takes place at the bottom of the bath, this is done to prevent splashing. The acid bath will be filled automatically.

Emptying

Emptying both baths takes place through a valve under the baths. A pipe can be screwed on the valve so the fluids can be drained into a barrel.
