THE REFINING PROCESS – COMPLEX, TIME CONSUMING AND CONST INTENSIVE
Tempered glass manufacturing is complex, time intensive and generates high energy and personnel costs, making it important to detect defects in the early stages of production. Many businesses continue to rely solely on their staff to inspect the glass manually before it is put through the tempering furnace. However, this method can be very unreliable when inspecting horizontally laying panes of glass, especially when the lighting is not sufficient. The place of inspection can have a further negative impact on the production lines’ efficiency, as defective glass cannot be replaced immediately. The full capacity of the tempering furnace can therefore not be exploited, and may even cause supply shortage due to the time consuming re-working of the glass.
THE FIELDS OF APPLICATION
The many options presented by digital image processing replace flawed, manual inspections with automated and quick processes that reliably pin-point even the smallest defects. With the Viprotron systems you can optimize every stage of your tempered glass production line.
After the edge processing
After the Double edger the Quality Scanner inspects the panes for glass and coating defects and for dirt. The defective glass can then be reworked or taken out of manufacturing. The system is therefore placed directly after the washing machine.
An ECO Scanner is also a good choice if you are only looking for high-contrast defects such as bubbles, inclusions or scratches. It also helps you, for example, before printing a pane to check whether the glass for the expensive process also meets the quality requirements.
After drilling or milling, after the washing machine
A Quality Checker SG placed directly after the washing machine is ideal for detecting glass defects, for inspecting the positioning and measurements of the drilling and milling process as well as for checking the exact dimensions of the glass panes.
After the furnace
The Anisotropy Scanner measures at full production speed with polarizing light in transmission and indicates whether the isotropy minimum target value of the single glass has been reached or exceeded. At the same time, the Anisotropy Scanner can provide valuable information for the process control of the furnace to improve the product quality.
After the tempering process, the White Haze Scanner can be used to detect areas where furnace-related damage to the glass surfaces has occurred. These are analysed and localized in real time as soon as they occur, so that the defects can be polished out before delivery to the customer.
