What are the processes of glass processing?

1, the selection of the original film: first of all to do Dongguan glass processing of course must have the original glass sheet, the ordinary Dongguan glass processing factory is not the production of the original sheet, the thickness of the original glass sheet is not the same, if it is the production of display glass generally choose the thickness between 1mm, 2mm, 3mm, because digital products have relatively high requirements for light transmission, so will choose ultra-white glass.

2. Dongguan glass processing size cutting: The size of the original piece itself is very large, generally more than three meters long and more than two meters wide. Cutting can be said to be the first step in glass processing, and 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 glass edge behind. Therefore, there is also the term tolerance.

3, glass grinding edge chamfer: freshly cut glass will scrape hands, glass edge will be very sharp, customers will also require grinding edge, but grinding edge has grinding fog edge and bright edge, installed in the frame of the grinding fog edge on the line, this can also reduce the cost, polished edge is those customers who have a relatively high aesthetic of glass requirements. After the edging is the chamfer, and the chamfering also has a special chamfering machine, through which the desired R angle can be accurately poured.

4, tempering: tempering is divided into physical tempering and chemical tempering, we talk about physical tempering here, physical tempering is to heat the glass in the tempering furnace to a certain extent, and then cool it, the hardness of the glass is enhanced after tempering. Customers will ask for glass tempering, so that it is safe. 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. Screen printing also has high-temperature silk wire and low-temperature silk screen printing, and high-temperature silk screen printing will be carried out in the first step of tempering. The screen printing room should be relatively clean. In this way, the ink will not be incorporated into the magazine. The effect of silk screen printing will be better.

6. Cleaning and testing packaging: the last glass must pass the inspector's inspection, and the problematic glass will be selected, some will be scrapped, and some can be underprocessed. The good glass is coated by a film applicator and then wrapped in kraft paper.
