What are the processing methods for glass?

1. Selection of original film: First of all, glass processing must have glass original film. Ordinary glass processing factory does not produce original film. Only large glass companies produce original film, such as Xinyi Glass and CSG Group. The big company is only producing. The thickness of the original glass sheet is also different. If the glass for the display type is generally selected to have a thickness of between 1 mm, 2 mm, and 3 mm, since the digital products have higher requirements for light transmittance, ultra-white glass is selected.

2, glass size cutting: the size of the original film itself is very large, generally more than three meters long, more than 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. This algorithm must take into account the size consumed by the back edge of the glass. Therefore, there is also a statement of tolerance.

3, glass edging chamfer: just cut glass will be scratched, the glass edge will be very sharp, the customer will also require edging, but the edging has the edge of the fog and the bright side, installed in the box It is also possible to reduce the cost of the fog, which can also reduce the cost, and the polished edge is required by customers who have a relatively high aesthetic appearance. After the edging is chamfering, the chamfer also has a special chamfering machine, through the chamfering machine can accurately pour out the desired R angle.

4, tempering: tempering is divided into physical tempering and chemical tempering. Here we talk about physical tempering. Physical tempering is to heat the glass to a certain extent in the tempering furnace, and then cool it, and the hardness is enhanced after glass tempering. Customers will require glass tempering to be safe. Tempered glass is also known as safety glass.

5, silk screen: some glass will go through this step, because the customer wants to print some patterns on the glass, company logo and so on. Silk screen also has high temperature silk and low temperature silk screen, high temperature silk screen will be carried out in the first step of tempering. The screen printing room should be relatively clean. Thus, the ink does not incorporate impurities. The effect of silk screen printing will be better.

6, cleaning and testing packaging: the back glass to pass the test of the inspector can pass, the problematic glass will be selected, some will be invalid, and some can be processed less. Good glass is filmed by a film machine and then wrapped in kraft paper.
