How is glass processed

Machining process

1. Selection of original pieces: first of all, glass processing must have broken glass original pieces, ordinary glass processing factories do not produce original pieces, only large glass companies produce original pieces, such as Xinyi glass, South Glass Group and other large companies. The thickness of the original glass is not the same, if it is the production of display glass generally choose the thickness between 1mm, 2mm and 3mm, because of the digital products on transmittance requirements are relatively high, so will choose the ultra white glass.

2, glass size cutting: the size of the original piece itself is a large block, generally more than three meters long, two meters wide. Cutting can be said to be the step of glass processing, the staff will calculate how to cut the original piece according to the size of the customer's drawings. The algorithm must take into account the size consumed by the rear glass edging. Hence the term tolerance.

3, glass edge beveling: just cut glass is scraping hand, glass edge will be very sharp, customers will also ask for edge grinding, but there are dews with bright edge grinding, installed in the frame of dews on the line, so that can also reduce the cost, polishing edge is the glass of high aesthetic requirements of the customer. After the edge grinding is chamfering, chamfering also has special chamfering machine, through the chamfering function of the desired R Angle.

4, tempering: tempering has physical tempering and chemical tempering, we talk about physical tempering, physical tempering is the glass in the tempering furnace heating to a certain degree, and then cooling, glass tempered hardness enhancement. Customers require tempered glass to be safe. Tempered glass is also known as safety glass.

5, screen printing: some glass will go through this step, because customers want to print some patterns on the glass, the company logo and so on. Screen printing also has high temperature silk and low temperature screen printing, high temperature screen printing will be in the step before the tempering. The screen printing room is cleaner. So the ink will not be mixed with the magazine. Silkscreen printing will be better.

6, cleaning detection packaging: surface broken glass to pass the detection of the inspector can pass, the glass will be selected, some obsolete, some can be processed again. Good glass through the film machine film, and then kraft paper packaging.

The above is the glass processing factory glass process. A piece of finished glass goes through many processes.
