glass edge working process

Nowadays, glass has penetrated into people's lives, and glass products can be seen everywhere, such as glass cups for drinking water, glass windows, glass doors, screen protection glass on computer monitors, mobile phone screens, and glass buildings, etc., especially It is the touch screen used in mobile phones and tablet computers, which will occupy a large proportion in future production!

First, briefly understand the glass processing process of electronics and displays

1. Selection of original pieces: First of all, glass original pieces are of course required for glass processing. Ordinary glass processing factories do not produce original pieces, and only large glass companies produce original pieces.

2. Glass size cutting: The size of the original sheet itself is large, generally more than three meters long and two meters wide. Cutting can be said to be the first step in glass processing. The staff will calculate how to cut the original piece according to the size on the customer's drawing.

3. Glass edging and chamfering: the glass that has just been cut will be scratched, the glass edge will be sharp, and customers will also require edging, but the edging is divided into a fogged edge and a bright edge, which are installed in the frame. It is enough to grind the foggy edge, which can also reduce the cost. The polished edge is required by those customers who have high aesthetics of the glass. After edging is chamfering, and there is also a special chamfering machine for chamfering, which can accurately pour out the desired R angle through the chamfering machine.

4. Tempering: tempering is divided into physical tempering and chemical tempering. We are talking about physical tempering here. Physical tempering is to heat the glass to a certain extent in a tempering furnace, and then cool it down. After tempering, the hardness of the glass is enhanced. Tempered glass is also known as safety glass.

5. Silk screen printing: Some glass will go through this step because customers want to print certain patterns, company logos, etc. on the glass. The screen printing room should be relatively clean. This way the ink will not be incorporated into the magazine. The screen printing effect will be better.

6. Cleaning, testing and packaging: the last glass must pass the inspection of the inspector before it can pass the customs. The glass with problems will be selected, some will be discarded, and some can be under-processed. The good glass is filmed through the film machine, and then packed with kraft paper.

The above is the general process of glass processing in glass processing plants. A piece of finished glass goes through many processes. The second and third processes are closely related to our cutting and polishing industry.
