How to glue plastic glasses frames. Do-it-yourself eyeglass frame repair. Causes and types of breakdowns

Glasses are an essential item for all people with poor vision. But this household item is not always treated with care. As a result, they break, break, or lose screws. But this is not a problem, because you can glue plastic glasses at home using glue.

However, to achieve reliable fastening, you need to select an effective adhesive mixture.

What glue can be used to glue glasses - choosing equipment

Gluing plastic glasses yourself is not as difficult as it might seem at first glance.

All the tools you need to repair work, are likely to be easily found in the house:

Mini drill with a thin drill bit (0.3-0.5 mm.);

Needle;
Thread;
Degreasers (alcohol or nail polish remover);
Stationery erasers;
Textile;
Cotton buds;
Ruler;
Glue.

Not every glue is suitable for repairing broken plastic glasses.

To do this, you need to look at one of several types of glue:

Bison Plastic. Effectively used for strong bonding of plastic glasses and a variety of household plastic items such as polycarbonate, plexiglass and PVC. It's also great for renovations. plastic toys, remotes, mobile phones, fastening of plastic auto and bicycle parts, PVC pipes. It is highly durable, waterproof, transparent after drying, and can withstand temperatures in the range from -20 to +100 degrees. Cost of a 25 ml tube: 290 rubles.
Moment Plastic. Glues different kinds plastic (polyurethane, polystyrene, soft and hard polyvinyl chloride) with each other and with other materials. Excellent for fixing hard-to-glue plastics: ABS, polyethylene and polypropylene. Possesses high speed gluing, frost- and moisture-resistant, resistant to solvents, provides a strong adhesive seam that is resistant to aging. Glasses repaired with this glue will last a very long time. Cost of 30 ml tube: 160 rubles.
UHU Plast Special. It can be used to reliably glue glasses and plastic parts. Provides a strong hold on rigid plastics and polystyrene, as well as plastics with other household items. Perfectly fills seams and microcracks thanks to the dispensing needle, which allows you to apply glue in the most hard to reach places. After drying it becomes transparent. Cost of 30 ml tube: 375 rubles.

How to glue glasses frames - step-by-step instructions

Often glasses break in half at the place where the nose bridge is located. When all the equipment is prepared and you buy the necessary glue, start gluing the frame.

Here is an example of repairing glasses frames using Bison Plastic glue:

Use sandpaper to clean and sand the broken surfaces that need to be glued;
Degrease the surfaces to be bonded with nail polish remover gel or alcohol;
Cut a piece of wooden ruler so that its length is the same as the distance between the side parts of the glasses - this will allow you to fix the glasses in one position, which will improve the quality and ease of repair;
To avoid scratches on the lenses, cover them with paper;
Attach a wooden ruler to one half of the glasses, attach them to each other with a rubber band. Do the same with the second half of the glasses, while pressing it tightly against the first half;

Ensure that the two broken parts of the frame fit snugly;
Slowly squeeze the glue into the seam at the fracture site;
Fill the joint completely so that there are no gaps or voids;
Use a cotton swab to wipe off any remaining glue before it dries;
Leave the glasses in this position for 2 hours until the glue dries completely;
On the nose bridge, on both sides of the joint, make one hole with a drill;
Around the joint, pull the thread through drilled holes. To do this, use a needle. The color of the thread should match the color of the frame;
Pass the thread through both holes until they are filled tightly;

Cover the holes with a large amount of glue so that the thread is saturated;
Remove the remaining adhesive mixture with a cotton swab and cut off the excess thread;
Set the glasses aside for a day to allow the glue to dry completely.

Gluing the temple of the glasses

Often problems arise due to a broken earpiece.

If they break in half, there is effective method glue the temple of the glasses tightly:

In the middle of the ends of both broken parts of the bow, drill one longitudinal hole;
In each broken part of the bow, next to the ends, make two through holes so that they create a square around the joint, and the longitudinal hole is in the center of this square;
Between the pairs of upper and lower through holes, using a chisel, cut small grooves into which you will later need to lay the wire;
Fill both longitudinal holes drilled at the ends of the bow with epoxy glue or glue containing acetone;
Insert a steel wire rod into one of the longitudinal holes so that it protrudes slightly outward;
Apply a thin layer of glue to both split ends of the temples;
Connect both broken parts by placing one half of the bow on the rod protruding from the other half;
The joint must be tight, do not allow voids;
Wipe off excess glue with a cotton swab;
Roll the seam nichrome wire, pulling it through the through holes;
Use it to tighten the split parts to increase the bonding strength;
Hide the protruding wire into the previously cut grooves;
Twist the ends of the wire, making a turn;
Cut off the remaining wire with wire cutters;
Let the glasses dry for another day, after which you can continue wearing them.

Glasses that are constantly worn are most often exposed to extreme conditions, and therefore sooner or later get damaged. In this case, it is customary to contact a repair shop, paying considerable sums to restore the frame. But it turns out that you can repair glasses yourself, if you first understand their structure and learn the basic restoration techniques. In some cases, soldering of glasses will be required, but often you can do without it.

Main structural element, holding the temples and frames of glasses together is a hinge unit, which can have two designs.

In one of them, the bow is attached using the usual screw connection. A more complex design is the design, in which a special spring-loaded mechanism called a flex is used for fastening.

In the simplest case, when the malfunction is associated with unscrewing a screw from the fastening unit, it is enough to simply return it to its place using a clock screwdriver or a well-sharpened knife. No soldering is needed here.

Glasses with flexes

If there is a flex, the repair of glasses becomes significantly more complicated, since the fixing screw in this case passes through the movable bar, and when it falls out, it is pulled into the cavity behind the ear.

In this case, two mounting holes that coincide in the normal state, after this breakdown, due to the action of the spring, lose alignment, so that the screw cannot be returned to its place. The only possible way out of this situation is to move the bar back into place and screw the mounting screw into the hole.

To return the bar, the easiest way is to use an awl or a needle, which allows you to catch on a small protrusion extending beyond the temple of the glasses. To carry out this operation, two hands are usually not enough, so you will need either outside help or a small vice (clamp).

In the second case, the temple body is first clamped, after which you can try to screw the screw into place. In the case when the material of the earhooks is very soft, it is advisable to pad them with a piece of leather.

If the screw is damaged or lost, it can be replaced with any suitable size and thread. If the diameter does not match, it is screwed with force into the mounting hole, thereby cutting a new thread. You can also use a piece of copper wire suitable section, which, after installation in the hole, is riveted on both sides.

Flex repair

For some glasses, the earpiece (arm) breaks at the point where the hinge is attached to the flex itself, which forces you to choose one of two solutions: complete replacement or repair. Since this part can only be changed together with the glasses, let’s look at the structure of the unit and the procedure for restoring it in more detail.

A careful study of the design shows that at the end of the temple there is a rectangular groove into which a steel strip about 1 mm thick fits. It usually breaks when this part of the glasses is damaged and needs repair.

A possible option for restoring it is to connect it in the broken place using a rivet.

As such a part, you can use a brass sewing pin with a head about a millimeter in diameter, for which you need to drill holes in the parts to be connected. When marking, one of them is marked in the center of the ear hook (arm) so that it coincides with the center line of the strip fixed in the hinge. Only after attaching this part will it be possible to clearly mark and then drill holes in both halves being connected.

Lens mount

In some models of glasses, the lenses have a rigid mount in half the rim, and their open part is held in the frame by a fishing line recessed in a special groove. This method of fixing the lenses makes the glasses more elegant in appearance and comfortable to wear by reducing the weight of the frame.

But all these advantages come at the cost of the inconvenience that they can easily break if neglected. Here, just like when repairing flexes, the following two options are possible:

if the lens jumps out of the mount, but the fishing line remains in its place, due to its elasticity, the optical element of the glasses can be easily installed in its previous position;
in a situation where the fishing line has completely fallen off the frame, it will need to be completely replaced.

In the latter case, you should not be upset and immediately contact the workshop, since such a malfunction can easily be fixed with your own hands. This problem can be solved with the help of a strong fishing line with a cross-section of 0.8 mm, from a skein of which a piece of approximately ten centimeters in length is cut.

After removing the old line, you should make sure that the ends of the new piece easily fit into the fixing holes, and if not, then sharpen them a little (cut along an oblique line). If in this case the fishing line does not fit into the holes, it is necessary to expand them in some way (sometimes you even have to drill out this part of the fastening).

After the ends are inserted into the holes, and the size is measured strictly along the length of the arc of the lens, you should heat the ends with a soldering iron, then securely fix the optics in the frame. This is a case of using soldering to repair glasses.

If the frame is metal and the metal of the lens holder has broken, then soldering can be used for repair. The holder is soldered using rosin as a flux (for stainless steel and steel, zinc chloride is better), and the solder is chosen either tin-lead or in accordance with the characteristics of the metal of the frame.

Repair of earhook and temple

There are often cases when one of the temples of glasses breaks into two parts, and the breakdown occurs in the area of \u200b\u200bthe junction of the metal and the plastic tip, fixed to the pin with a screw. In this case, of course, you can use the method of laser soldering of metals, but this option is difficult to implement at home.

It is much easier to use for this purpose a brass plate of the appropriate shape and thickness of 1 mm, connecting both halves ground at the point of contact.

Two holes are drilled in the cover, and there are fixing bends on each side. The size of one of the holes coincides with the relief grooves in the openwork pattern of the metal part, while the second is made arbitrary. After assembling the temple into a single unit, it takes on a completely wearable appearance.

The frame of the temple can be restored using the same methods as the temples. However, in this case, it would be wiser to purchase a new, not very expensive frame that matches the color and structure of the metal. Rearranging it instead of the old broken part will not be difficult.

Metal frame bezel

If the metal rim of the frame breaks, serious repairs will be required, since this place experiences strong deformation loads.

The simplest solution is to glue the metal frame directly to the lenses of the glasses. At the same time, the gluing area increases significantly, which ensures the necessary strength of the formed connection.

For these purposes, the well-known brand of universal glue “Contact” is optimally suited, the strength of which only increases over time. To prevent glue from getting on the plastic lenses, a strip of tape must be glued on both sides of the connecting seam. If the lenses are glass, then you can do without this, since the glue from the glass comes off quite easily.

Plastic frame (rim)

To solder glasses frames or rims made of thermoplastic material, you will need a soldering iron or similar heating device. They are necessary for heating the plastic in the area of fastening broken parts that are joined in a molten state. This is not soldering in the full sense of the word, since solder is not used here.

You can do without soldering tools if you use dichloroethane or benzene, which melts the plastic to the desired state at normal temperatures.

Regardless of the chosen heating method, the parts of the frame, softened to the required state, are tightly pressed against one another and held for some time sufficient to obtain a reliable diffusion connection.

Laser repair

The laser soldering method belongs to the category latest technologies allowing for very fine repairs of metal frames of any shape. The local heating of the contact zone makes it possible to preserve the adjacent areas in an undeformed form.

Laser restoration of parts is carried out using a special microscope, which affects the cost of all repair operations.

You can solder using this method both in a vacuum and on outdoors; Moreover, the use of fluxes in this case is not at all necessary. When soldering glasses, it is preferable to use the pulsed operating mode of the laser device, using solders that match the steel grade of the arms or rim.

Professionals solder titanium, composite and steel frames and know how to choose the right solder. Laser soldering low power can lead to parts of the glasses falling apart again after a while, so the choice of device power plays a big role.

How to save your glasses

In order to protect your glasses from breakage, you need to adhere to the following recommendations:

It is best to wear them with a special safety cord to prevent the product from falling and being damaged;
before removing clothes, do not forget to take off your glasses to avoid breaking them;
It is better to store them in a case specially designed for this purpose.

We also note that when not in use, it is advisable to fold the temples, without leaving the glasses in a dangerous and unstable position.

Today I crushed my favorite glasses.
I thought I’d come home and glue the frame. but the Indian people's dwelling is figvam. Dichloroethane does not take this plastic. In general, I have little idea what kind of plastic glasses frames are made from in general and this “Nina Ritchie Made in France” in particular.

Therefore QUESTIONS:
1. Is it possible to repair/glue/weld such a fracture in such a place?

if not, then

GRbIzLi max 27-05-2011 16:02

Soldering iron?

ag111 27-05-2011 16:07

You can melt it with glue for glue guns, I solder it like tin with a soldering iron. But it will be thick and ugly. Maybe UHU-300 epoxy will hold it in place.

No you can not. Great strength is needed in this place, and this glue has very poor adhesion. Also keep in mind that these are glasses - an object that is close to human skin, and it will be very difficult to degrease the seam area. TS says that dichloroethane did not take this crap, which means that most adhesives nervously smoke. If only superglue, but it will leave ugly marks.

2. Where is the most affordable place (these glasses are from Lizmaster many years ago and are not cheap at all) you can choose a frame + order glasses with tinting (or sun protection with diopters)

Probably in the salon of the same name "Ochkarik". In general, steel frames rule

LazyLionR 27-05-2011 16:27

steel frames

I don’t know, then (about 10 years ago) I spent a long, long time choosing this lensmaker (they gave me a discount card to use, so I went there) I liked these Nina Riches the most.

So, from then on, they lived with me, until, damn it, I crushed them today

vgrom 27-05-2011 21:32

buy new ones - after all, they will last for 3-5 years and don’t bother

There is a two-component adhesive for repairing bumpers. even glues polyethylene. after polymerization it acquires a milky color. The problem is that it is very expensive and the lifetime before polymerization is 5 seconds. I don’t remember the catalog number, but the manufacturer is an “evil painter”. look around, car forums...

c00xer 28-05-2011 13:30

Well, obviously cheaper than a new frame.

But this is the problem. Because during this time it is unlikely to be applied evenly and beautifully. I glued it with similar glue - it was terrible - a droplet that had dried to the steel surface could not be removed. Cut it with a Dremel. There is such a double syringe, it is inconvenient for gluing small parts. It also gets very hot when it freezes.

ag111 28-05-2011 13:37

Yes, in 5 seconds, you have to be a speed fakir.

very expensive how much is it? I googled 3M eFPieReM and found that it comes in 25ml and 150ml packages. But I didn’t google the price... Actually, 25 ml is enough for that place - you need to seal it sooo many times...

At one time I glued it with superglue, and then from the inside I pressed something like a stapler clip into the frame with a soldering iron, only small and cut off. It looked normal on the outside, but on the inside, of course, it wasn’t great.

There is a similar one. Yesterday I bought a moment for 70 rubles. I used to use Canadian, but now I've switched to Chinese.
BTW, I read the composition - a hardener based on polymercaptan. But how would you depolymerize it, huh? It will be a funny thing

We need a jeweler who can fit the pin inside.
Or rather, you need a thin drill and a Dremel. Drill holes 1-2 mm deep from the ends. Take a piece of paper clip. Sand this piece with coarse sandpaper so that the glue adheres better. Dip it in super glue, for example, or something else, and carefully push it inside.
IMHO it will last forever.)))

PS I would go and buy new glasses.)))

LazyLionR 30-05-2011 16:29

The question has been temporarily removed. my wife gave me "super-duper second glue." in general, naturally, cyanoacrylate, BondMagic super glue three-gram tube made in Taiwan.
I smeared it and pressed it. it seems to have stuck together. I removed a small drip from the frame with a scraper.
Moreover, it didn’t stick quite “as it was,” that is, with a tiny step, almost imperceptible.
I thought that when I inserted the glass, then everything would be decided. I insert it, I feel that it “spreads the frame, pulls... pulls, and... silk, the glass is in place. The frame is “intact”. We will continue to observe.

Are your glasses broken? You can take them to a workshop or buy new ones, or you can repair the glasses yourself, using materials and tools that can be found in every home. Our instructions will tell you how to repair plastic glasses.

Materials and tools for repairing glasses:

drill with a very small drill bit
needle with thread
Super glue
nail polish remover
cotton buds
wax paper or soft cloth
stationery erasers
wooden slats

1. To repair glasses, clean, sand and degrease the plastic at the break point.

2. Prepare a jig (a device that allows you to secure the frame parts in a certain position) to fix the glasses.

A wooden strip or an old ruler will serve as a conductor. Cut the rail so long that its length is slightly less than the width of the glasses.

Wrap the piece of wood in waxed paper or a soft cloth. This is necessary in order to protect the lenses from contact with the surface of the conductor.

3. Secure the glasses to the conductor. Attach a fragment of the frame to the rail and wrap it several times with a rubber band.

First make sure that the rubber bands are clean and will not stain the lenses of your glasses. Then attach the second half of the glasses, pressing it well to the first. Use the rubber band again.

Align the parts of the glasses with each other, making sure once again that they are touching.

4. Apply glue to the place where the glasses broke. This is the most critical stage of repair, so everything must be done very carefully.

Fill the broken area with glue, make sure there are no voids or air bubbles.

Quickly wipe the surface with a cotton swab to remove excess glue.

Let the glue dry for an hour.

5. Drill holes to attach the bandage. After the glue has dried, you need to drill one hole in the frame on each side of the break.

Put your glasses on soft cloth. Drill very carefully so that the connection does not break. Try to make the holes not too close and not too far apart.

In our example they are placed too close.

A bandage is simply a thread pulled through drilled holes and wound tightly over a glued joint. The bandage is needed to strengthen the connection.

Pull the thread into a thin needle. The length of the thread folded in half should be about 60 cm.

First, pull the thread through the drilled holes as many times as possible. If the needle no longer goes through, you can start winding the threads around the bow. Wind the thread tightly, but do not overdo it, so as not to break the glasses again.

6. Apply glue to the bandage. Use a needle to remove air bubbles if they form. Let the thread soak and remove excess glue with a cotton swab. Let the glue dry for 15 minutes, trim off any protruding ends.

7. Take a long thread and glue one end of it to the bow with masking tape.

Wrap the temple of your glasses completely.

Glue the free end of the thread to the frame.

Treat the resulting joint with glue, blot it and let it dry a little.

8. Wind the thread in the opposite direction. After the glue has dried, release the end of the thread that you secured with masking tape and wind it around the bow, moving in the opposite direction. As a result, the upper and lower loops should lie crosswise - this way the connection will be as strong as possible.

Treat the threads with glue again and let it dry. Trim the ends.

Do not use glasses for 24 hours to allow the glue to completely dry and set.
