Cutting protective glass for smartphones with a laser. Alternative solutions to the problem

Is it possible to cut glass on the phone?

After buying a new smartphone, the user seeks to protect and protect the device from damage as much as possible. In this case, additional accessories and protective elements come to revenue.

Previously, at the peak of popularity, there were protective films that allow to protect the screen from small mechanical damage.

Today, the question is increasingly asking how to stick protective glass on the phone, because today it is precisely it leads in the issue of ensuring the integrity of the display.

What is a protective glass

Uninitiated users do not see much difference between the usual film and protective glass. It is as flexible and elastic. But still it is glass, and an additional hardened and especially durable one, capable of protecting the screen from most possible damage.

The accessory is great for people who often drop smartphones or are afraid to scratch the screen. The coating perfectly strengthens the screen and allows you to maintain the integrity of the display, even if the gadget falls downward.

If, nevertheless, the blow turned out to be very strong, the protective glass will not allow fragments that can be very dangerous.

In connection with more significant characteristics, the cost of such an accessory is much higher than, for example, film.

In this case, the glass cannot be cut under the gadget, so you have to buy finished products adapted for a specific model.

The question of how to stick protective glass on the phone is interested in users due to the fact that it costs extra money in the cabin, but you can cope with the process yourself.

The coating thickness ranges from 0.18-0.33 mm. It can add weight to the device and make it somewhat more voluminous, you need to be prepared for this.

Protective glass consists of several layers:

• Silicone substrate necessary for the most strong fixation of the accessory on the screen;
• The next layer, restraining, fixes glass fragments and does not allow them to crumble in case of a serious blow;
• The protective layer responsible for the strength of the glass itself;
• Anti.focal layer. provides a comfortable use of the gadget even in sunny weather;
• Oleophobic layer is a coating, thanks to which prints do not remain on the display.

Glass does not affect the sensitivity of the sensor, does not spoil the image, that is, allows you to use a gadget with no less comfort. Thanks to all the advantages of such protection, it has become in demand and quite justifies the expectations of the consumer.

How to stick a protective glass on the phone

As mentioned above, you can stick a protective glass on a smartphone yourself. To do this, follow some recommendations.

Materials and tools

Despite the fact that the process is available, you should first prepare the necessary tool so as not to be distracted. In order to independently stick protection on the screen will be needed:

• alcohol napkin, they can be bought at a pharmacy;
• dry soft rag;
• liquid for cleaning displays and TV screens, it can be bought or mixed yourself, for this you will need water, alcohol and a dishwasher;
• vacuumber or tape (to attract dust dust);
• Protective glass itself.

In addition, a plastic bank card may come in handy if there is no special spatula with protection with protection.

Preparation of the workplace

In addition to preparing the tool, it is necessary to prepare a workplace. It is important that it is not dusty.

It is best to carry out the procedure in the kitchen or in the bathroom.

The smaller around the tissue material, the less dust, which will definitely settle on the screen much faster, the more you expect.

The table on which the work will be done should be thoroughly wiped with napkins. Before the start of the process, hands also need to be washed with soap in order to get rid of accumulated fat. After everything is ready, you can start directly to the process.

Sticking algorithm

Not everyone knows how to stick protective glass on the phone, but subject to the recommendations that we describe further, difficulties should not arise.

So, all the inventory is assembled, the workplace and hands of the master are prepared, we move on to the main stage.

• Prepare the gadget display. Remove the old coating, for this, carefully pick up the edges and pull. Regardless of whether the factory film on the device or purchased, it exfoliates very easily.
• Clean the surface of the sensor with an alcohol cloth or a cloth with a screenwriter. It is important to carefully process the entire surface, so as not to leave pollution. The display must be grate to the maximum shine.
• If dust flows remain on the surface, then the line came to use a vacuum cleaner or tape. The whole process is aimed at attracting particles of dust with static electricity (and in no case do not glue the tape on the screen).
• We take out the screen from the package and remove all the protective films from it. Combine all the elements of the screen with holes on the glass (central button and speaker). Make sure that the defense comes down smoothly with the edges of the device and lay down exactly. At the same time, you need to hold the glass by the edges so as not to slap it. If you doubt that you can handle it, it is better to wear medical gloves.
• Fasten the protection by running your fingers from top to bottom the center of the display. Then, using a spatula or credit card, remove the remaining air, characteristic movements from the center to the edge. If small droplets of air are left, this is not a problem. He will come out in a few days himself. Therefore, do not crush excessively on the display.

If all measures are met and recommendations are made, then the user will receive a perfectly even coating without divorces and cloudings. If the latter appeared, then the screen was poorly cleaned. To get rid of jambs, you can peel off the glass and repeat the process.

Is it possible to overlap the protective coating

This question follows from the previous problem. Is it possible to remove the glasses and clean the screen or re.re.protect from one gadget to another. If the surface of the protection is not worn out, then this approach is quite appropriate.

In this case, additional processing of the adhesive silicone layer is required. Use ant alcohol for processing.

You need to carefully remove the glass, and wipe the adhesive side with a rag with a plentifully moistened liquid.

Step.by.step glass sticker instructions

First, the phone is removed from the cover and disabled. Then the old protective coating or glass is removed from the surface.

• Degrease the surface of the screen with a tool for cleaning monitors, an antistatic agent or alcohol (a set from a set).
• Dry, wipe the screen with microfiber fabric to the gloss (a set from a set).
• If dust flows remain on the surface and after that, they are removed with tape.
• The film is removed from the protective glass, pulling the tongue.
• Holding a protective coating at a distance of 1 cm from the screen, make an fitting: speakers and buttons must coincide with the corresponding holes.
• Lower the glass on the display. Since the surface is adhesive, the coating is quickly connected to the display.
• If air bubbles appear under the glass, they are trying to remove them with a microfiber or plastic card. In both cases, they move from the center to the edges.

Glasses are more often produced for specific models of smartphones, less often. universal, designed for a certain diagonally display. But in the first and second cases, you must first provide an fitting and determine how exactly the protective coating should be located on the smartphone.

If the phone on which the protective coating is glued is only bought, then it is not necessary to clean the surface of the display. It is enough to easily remove the factory protective film from the screen.

Smooth glass placement

Not everyone is able to glue the glass even the first time. Ordinary stationery adhesive tape will help to place it correctly. Then they do this:

• A tape is glued along the edge of the smartphone to the rear panel.
• Excess tape from above and below is cut off.
• Glass is exposed exactly how it should be glued to the display, an adhesive surface down.
• With one hand, the glass is fixed on the smartphone, the other glue the tape to the protective coating.
• Glass leaning back like an cover in a book.

After the glass is fixed in the correct position, you can clean the display. After gluing, as described above, tape is removed.

Removing dust

If a snorka is between the surfaces, an air bubble forms around. Only smoothing the microfiber cannot remove it. But you can still fix the situation.

The process of removing dust dust under protective glass

• With a plastic card or tape glued to the coating, the coating is raised to the place where the dust is located.
• A piece of adhesive tape is glued to the monitor glass in the dust area. They abruptly tear off the tape.
• Lower the protective coating in place.

Auxiliary remedy

In order for gluing protective glass to be more comfortable, you can find a gel to fill the air bubbles on sale. Often they are formed along the edge.

Such funds are produced in two forms. in a bag or in a pipette. The liquid is not afraid of temperature differences, so even in the frost is not immersed. One bag is enough for several applications.

Gel to fill the air bubbles that form after gluing protective glass on a smartphone

• Open a pipette. They are smeared with liquid at the edges where glass retreats.
• Let the device lie down so that the liquid spreads under the protective coating.
• The remnants of the product are removed with a dry cloth.

The thinner the applied layer of fastening gel, the better the result.

Cutting protective glass with a laser

This method is suitable for those who have access to a laser engraver of a suitable size. It is the laser cut of protective glass that is originally used in the manufacture of protective glasses from sheet material. This type of cut allows you not to damage the layers present in the protective glass, although this option is quite expensive.

Little by little, we got to the most important thing, namely, to the instructions, how to correctly stick glass on the phone screen. It is worth saying that the task is, although simple, but very responsible, since incorrectly glued glass will not be glued and you will have to buy a new. Therefore, before starting work, carefully read the instructions and make sure that you have all the necessary tools.

Type of glass

2D / flat glass without a frame. glass with rounded edges. This glass completely closes the flat surface of the screen of the mobile device.

2D / flat glass without a frame / hybrid. hybrid glass combines a small thickness of a protective film with high hardness of the glass. Hybrid glass is more flexible compared to ordinary glass, and this makes it more resistant to blows. The disadvantage is a great susceptibility to the appearance of scratches. This glass completely closes the flat surface of the screen of the mobile device.

2.5D / flat glass with a colored frame. the glass completely closes the surface of the curved screen of the mobile device. Glass with a colored frame looks more natural and implicitly on the smartphone screen.

3D. completely repeats the shape of the rounded edges of the device screen, which allows you to protect the screen from mechanical damage as much as possible.

There is a belief that the larger the number D (5D, 9D, 10D), the better. In reality, this is not so. there is no system of evaluating glasses and assigning a certain number to them, it is just a name that each manufacturer comes up with his discretion.

How to cut hot glass?

Only one tool is permissible for cutting hot glass. laser. In the absence of this unit, at home you need to use another technique that implies a preliminary anneal.

The hydrogel film is created from polymer material that absorbs and holds moisture. It has high strength, capable of protecting the smartphone screen from the appearance of scratches and scuffs. Resistant to mechanical damage. Easily glued to the phone screen and quickly removed.

What is the thickness of the protective glass is better?

Modern protective glasses have a thickness of 0.33 mm. this is an optimal indicator in which the stiffness and protection against glass deformation remains, the touch panel of the phone and the edges do not look completely thick.

They are divided into three categories: 2D, 2.5D and 3D. The first includes flat glass with poorly processed faces. Usually they are not polished, since the edges of the accessory will fall deep into the corps. 2.5D models are flat with curved edges, they are designed for phones in which the screen smoothly goes into the case.

How to improve the quality of laser cutting?

Brent Donner, President of DLC Manoufacturing and Fabrication, has almost ten years of experience as a laser cutting consultant. During this time, he allocated several fundamental things that operators can lose sight of: proper cleaning and polishing of optics, nozzle centering and calibration of the focus of a laser beam.

Brent Donner is known for going beyond the borders of the existing boundaries. In the 1990s, he entered college to study metallurgy. This training allowed him to understand the basics of how different metals react to different production methods. He also has a natural ability to ask the right questions and raise experiments.

All this helped him create a reputation as a laser cutting operator, which can very carefully set the settings and create very clean, without a trace of defects, edges when cutting materials with a thickness of 1.5 inches and even thicker, which someone else could hardly do. “For some reason, it has always been natural for me”. Brent said. “I do not know why”.

Since 2007, Donner advised different manufacturers, helping them to squeeze everything that is possible from their laser cutting systems. In 2008, he began working at DLC ManUFACTURING AND FABRICATION. Since then, it remains a small enterprise on which high.class specialists work.

When Donner visits production as a consultant, he often sees how people, working on a laser cutting machine, lose sight of some fundamental things. Therefore, before delving into operating difficulties, he first asks them a few questions.

one.Have you cleaned the lens or protective glass correctly?

Cleaning procedures are divided depending on the type of laser. For a fiber or disk laser, operators need to clean the glass that protects the optics of the cutting head.

According to Donner, when he bought his first fiber machine, he turned to the recommendations of manufacturers. He made some changes in them, creating and improving his cleaning method. Using this method allows it to increase the service life of the protective glass. Its method is patented, but, in general, it carefully studies the protective glass for any residual film after cleaning and uses various ways to remove it. After that, the glass is clean, free from the film and is ready for the cutting process. “At our enterprise, we use a protective glass for a fiber laser from 6 to 8 months, before there is a need to use a new [protective] glass”. Donner said. “But at the same time, the conditions under which cutting is carried out must be correct”.

For carbon dioxide laser, operators need to clean the lenses. Donner and his team clean their lasers using Trumpf polishing. Topol Polish. “Many operators really do not know how to use it”. Donner said. “Often, when I enter the object, I see that the lens is very scratched. Instead of polishing it regularly, they simply invest in a new lens. But, after some time, it can become really expensive. “.

So, how to teach the operator to properly use polishing for lenses? “Each operator acts in its own way”. Donner said. Watching them, he pays attention to their dexterity, the movement with which they purify the lens, then determines how they can improve their lens cleaning technique. They should never put pressure on the lens with excessive power, it can scratch it hard. At the same time, they need to use sufficient strength to effectively remove pollution. You need to be able to observe the balance.

Donner uses a reasonable amount of polishing, removing pollution from the lens in circular movements, but it seems that this technique works only for it. “You need to understand how your operator works”.

In order to really polish the lens, the operator needs to see its shortcomings. Donner advises to purchase a polarizer for carbon dioxide lasers, which costs several hundred dollars. But if you use it properly, then investments in it will pay off as soon as possible. The operator just needs to put the lens on a device that illuminates it from below with bright light. This is somewhat reminiscent of ordinary projector, which is used in schools. “When you turn the polarizer lens, it will polarize the laser lens that you placed upstairs, and if it is in poor condition, you can see internal cracks and other shortcomings”.

Preparation for cutting: important points

In the hands of an inexperienced master who wished to cut hardened glass, the product will instantly fly on many fragments. The only effective option is cutting with a laser. However, at home, you can hardly find such a device. Therefore, you will have to go the other way that requires preliminary annealing. The instruction will be given further.

It is important to consider the fact that, as the re.exposed glass cools, its outer part will cool faster than the internal. If the surface of the glass has already cooled down, this does not confirm the readiness of the internal part of the material. Due to the slow cooling of the glass, the formation of a large number of voltages is prevented in it. Due to this, it becomes possible to obtain a cut of higher quality. This moment must be taken into account with independent cutting of hardened glass.

To complete this difficult work, you will need the following:

• Directly fan.glass.
• Warm water.
• Bake.
• Thermoregulator. The presence of this element is desirable, but you can do without it.
• Marker.
• The square.
• Grinding stone.
• Glass cutter.
• Wooden rod. There will be enough product with a diameter of 6 mm.
• Protective glasses.

Step.by.step instructions for cutting hardened glass

Cutting hardened glass involves preliminary annealing of this material. The process includes uniform heating. The main task of this stage is to eliminate stresses that appeared in the material with previously made hardening. It is these stresses that are the main obstacle to cutting safe glass. Get rid of them. you can realize the planned.

The anneal is performed in the following order. First, the glass is soaked in water with constant temperature. You need to soak until a temperature corresponding to viscosity in the stove is reached. It equals η = 1013 Puaz. The time required for soaking depends on how much a large piece of glass you are going to cut.

Example 2. Turned glass cutting technology.

Glass brands Bullseye, Effetre and Lauscha are soaked at a temperature of 504 degrees Celsius. Borosilicate glass requires a higher soaking temperature, 566 degrees. And for the glass of the Satake brand the optimum temperature is 477 degrees. It takes an average of 20 minutes to soak off small beads. Larger beads must be withstanded for an hour. A large press-fad is withstanding 12 hours or more. Particularly large products weighing 40 kg and more in certain situations require hardening for a period of several months.

Glass must be gradually cooled to a temperature below the deformation temperature. It equals η = 1014.5 Puaz. The process should be performed quite slowly so that additional stresses do not occur. Satake brand glass cooles at a temperature of 399 degrees Celsius. A temperature equal to 427 degrees is suitable for cooling products of other brands. Glass must be cooled in the furnace to room temperature.

Put on the goggles and proceed to cutting anneal glass. Take a square, outline a fishing line for a cutting trimmer. The square must be kept along the left line. Cut the glass cutter along the line. Press with average force, making scratches along the marking line. Along the line, it is allowed to carry out only 1 time.

Next, you need to take a 6 mm wooden rod in diameter, put it under a fishing line for a trimmer cut and attach a quick and sharp pressing force on both sides. If everything is done correctly, the glass will break into 2 neat parts. The edges of the obtained parts must be treated using grinding stone. This will make the product more durable and safe.

If desired, the glass is subjected to repeated hardening. It is better if a professional is engaged in this work. The procedure requires appropriate skills and special equipment, so the newcomer will simply not cope with it.

Due to the fact that the process of cutting hot glass, which is in practice, is a cutting of an excessive glass, is a multi.step, you can simplify your task by buying a simple glass by cutting off the necessary areas or preparing the desired holes and hardening. This will save money, effort and time.

The list of necessary tools and devices mentioned the thermostat. It is needed to maintain temperature in the stove at a constant level. You can do without it, but it is easier with it.

Thus, cutting hot glass is very difficult. If you do not want to spoil the finished product, it is better to order a new hot glass or cut the usual material, and then perform or order it harden. Successful work!

Welcome! Now let’s find out how to stick a protective glass on the phone at home. We will do everything, as they say, “without dust and noise”, but the main thing is that without dust.

Replacing glass on a smartphone is not difficult, but there are “pitfalls” that you need to remember and know how to get around them. Our main task is not to bring a dust or hair under the glass during the gluing process.

We prepare everything you need

Let’s get ready, in addition to a smartphone, we will need: sticky tape or stickers, protective glass and a set of cleaning napkins, special stickers for removing dust dust from a set of an anti.jacket glass with an oleophilic coating.

It seems to me that you have already prepared all this, and if not yet, we order with free delivery to AliExpress. Learn how to buy on AliExpress, it is very profitable. There are good, but inexpensive protective glasses for smartphones or tablets and much more. I recommend preparing a couple of glasses in reserve, as they say in a folk proverb. “The first pancake is always lumpy”.

We find a place where there is less dust and are more comfortable

So, we should have two napkins in envelopes, but do not rush to open them. First you need to find a well.ventilated place where there is no dust in the air, for example by the window. We found a place, wonderful, now, before gluing the protective glass, put the phone on an even surface, it is better on a book, at home it will be so easier and more convenient to do everything.

Make sure that everything you need is at hand and you can start replacing the glass. First, clean the smartphone screen with a napkin saturated with alcohol solution, which comes in the kit. Then wipe dry with a dry cloth from the set, usually a deuce is drawn on the bag. Then take the glass from the cover, but it is early to peel off a transparent film.

How to cut glass without glass cutter

Tool for cutting glass did not always have such widespread as today. In the second half of the last century, people came up with their ways to conquer this capricious material, without the use of glass cutter. In fact, for cutting illegal glass up to 8 mm thick, you can use many improvised objects, you just need to have a little dexterity.

Start listing objects suitable for working with glass is better with determining the types of exposure to this material. Of the main methods, the thermal can be distinguished when the glass is heated in a certain place, and the physical, when it is cut through the effects of gross force. The industry uses a hydro.carbrease method of cutting when glass is processed on expensive equipment under strong water pressure.

To cut the glass by the thermal method, a small segment of twine and a flammable liquid like alcohol or acetone are enough, also a soldering iron and a burning device can be used as a cutter. To cut glass with physical influence, you can use a file, a winning drill, a nail, a thin diamond disk and even ordinary tailor scissors. Of course, some of the listed items are difficult to get a good chip, but with the proper skill, a quite suitable result may come out. Now, knowing how you can cut glass without glass cutter, you can proceed to the process itself.

Basic rules for successful cutting

In order for the cutting of glass to be crowned with success, some conditions must be fulfilled:

• Use a flat and stable base. In professional workshops, the table is protected by felt or felt. On such a surface, the product does not spin and does not scratch with fragments. At home, you can cover the surface of several layers of newspapers.
• Using a good ruler. Professionals use a special line with suction cups. At home, you can stick rubber on a regular ruler. So it will not slide on the product.
• Use only clean glass.
• Cutting tool must be lubricated. Professionals use special compositions. At home, you can use purified kerosene. In some modern glass cutters there is a special hole into which the liquid is poured. It helps when cutting the product.
• No need to press the tool hard.
• The cutting line for the cutting of the cut should be continuous. It is not allowed to draw one line several times with a tool. With such actions you ruin the tool cutting tool.

It is not recommended to perform work without protective equipment

So, we examined the process of cutting glass. You can cut glass at home, the main thing is to know how to do it. For cutting glass, you can use special tools or use improvised means, such as scissors or twine.

How to cut hot glass at home?

Cutting hardened (high.strength, safe, heat.resistant) glass. the process is not bouncer and difficult, requires quite serious preparation. Cut it according to the same principle as the usual one will not work because of its high mechanical strength.

In the process of hardening, the material changes its structure. The matter is also complicated by the fact that “safe” glass with all remarkable strength qualities is a very fragile material. When trying to cut it in the usual way, it will simply crumble into separate pieces.
