AG glass Screen Protector

What is AG Tempered Glass Screen Protector for Tablet PC?
 AG glass is also called anti-glare glass/non-reflective glass/non-reflective glass/matte glass .AG tempered glass is ordinary glass after "cutting → edging → opening → cleaning → heating into the tempering furnace to near softening point (about 700) → uniform rapid cooling → nano plating coating hardening


 

 Product features introduction

1) The surface strength of etching AG glass is much more outstanding than coating (spraying)AG glass:Etching AG glass is a chemical etching and it's still glass surface after etching(Etching thickness is 0.06~0.08mm).The Scratch-resistant degree is comparable to glass after being strengthened,( the spraying AG glass will be badly scratched after being used for some time),In addition, the tactile sensation of handwriting on etching AG glass is nearly similar to that of ordinary handwriting on paper

2) Longer product life::Because the surface of etching AG glass is still glass,the product life of it is equivalent to tempered glass and It will not cause AG layer to peel off because of environmental and usage factor

3) Outstanding fingerprint proof effect: the surface of etching AG glass has great fingerprint proof performance.

◊  Manufacturing process
1, cutting materials:


Step 1:check the process list( such as: Identify model/material/input/and cutting specifications)



Step 2:Check and confirm materials (Check the material/ materials’ thickness- open the box for air surface / scratches, etc.)

Step 3: Divide: (place the material air faces up and down to the cutting base, with X, Y as the position, start cutting equipment)

Step 4: Mark the air surface”7”: Mark the divided small piece air surface “7” as a the symbol for the subsequent identification of the air surface

Step 5: place to divided glass: place the divided glass air surface down in a plastic frame,mark the number of layers after overlap

Step 6: fill in the process sheet-( date/name/number of material used /.....) 

2, CNC actual operation:

 Step 1: Get materials depend on the order
Step 2: Calibration machine / base parameters:(Test machine running condition / cleaning base and correcting parameters of X/Y axis)
Step 3: caved(Lightly place the raw material on the cutting base, correct the position, start the cutting equipment)
Step 4: take the glass and self-inspection(Take the carved glass out of the base and look up at the light 45 degrees / hand touch the edge of the glass gently)
Step 5:  place divided glass-1: place the divided glass air surface down in a plastic frame, mark the number of layers after overlap
Step6: Cleaning: Insert 7 -face unified into the ultrasonic cleaning
Step7: Secondary dimension measurement:
Step8: Full inspection: place the single piece under incandescent lamp, take top/front/up/side view inspection and record
Step9:place divided glass-2 (storage),place the divided glass air surface down in a plastic frame, mark the number of layers after overlap
Step10: make the record and go into the next process

3,grinding

Step 1: Get materials depend on the order

Step2:Calibration machine(Test machine running condition and cleaning the corresponding suction cup..)

Step3:Mix grinding powder and test machine parameters

Step4: place the glass(7 words face upward, is placed on the grinding disc, open the negative pressure, please manually put the disc into the blanket and start to sweep)

Step 5: Removed the grinded panel,

Step 6:Insert the removed glass piece orderly

Step 7: cleaning: Use the prepared liquid/ultrasonic vibration frequency 2.1-2.2 to clean for 3 minutes, the water temperature is 60-80 degrees

Step8: Full inspection: place the single piece under incandescent lamp, take top/front/up/side view inspection and record

Step9: place the  glass pieces to the shelves slightly

Step 10: Step10: make the record and go into the next process


4,Glass reinforced

Step 1: Get materials according to the order

Step2: Calibration machine

Step 3:Ultrasonic cleaning 10 slots

Step 4: Adjust ultrasonic vibration frequency

Step 5: Parameter Settings,the water cleaning tank temperature is 70-75, and the baking temperature is 120-140

Step 6: verify the non-stick glass:pull the rising glass to keep neat,and the adhesive sheets must be manually isolated

Step 7: Drying :drying 3 minutes, and check the glass is dry or not

Step 8:Preheating/tempering.

Step9:Parameter of tempering:preheating 45minute-1hour temperature more than370degree,tempering 3-4hours,temperature: more than 385 degree

Step10: Soaking , Put the frame slowly into the water and soak for 15-20 minutes.

Step 11:Transfer Soaked glass from the iron frame to the cleaning rack

Step12: write the process sheet and place the glass onto the shelf
