Vidromecanica has developed an equipment for the rim finishing process able to carry out stemware and tumblers with a fine rim.

The thin rim characterises the glasses items of high quality.

The rim toughening treatment improves considerably the resistance  of the rim to the shocks.

These improved characteristics is a result of the stress profile that is induced in the glass, at the rim level, on a height of 20 mm from the top of rim.

The glass surface is in compression, while the centre is in tension.
