In major cities with a lively movement, minor damage to the body due to light clashes are common. To correct the dents obtained in this way, it is usually necessary to conduct, among other things, painting works. At the same time, the original factory paint coating of the machine case suffers.

Many motorists not to spoil the coverage, agree for a long time to drive through the streets of the city by car with a damaged body. It will be nice to know that now they have the opportunity to quickly get rid of the traces of these unpleasant "kisses" on the corps of their car. At the same time, even the slightest trail will not remain from dents, and the paint coating will not suffer at all.

PDR technology (DOL)

Paintless Dent Repair (in Russian - removal of dents without painting) is a relatively new service for the Russian market provided by some car services. But those who managed to use it, remained very pleased with the result.

This method was proposed in the distant 50s by German Oscar Flyge. PDR was used by the Mercedes-Bens plant. In those years, several factors have preserved the spread of this technology: secrecy, high cost of equipment, high metal thickness used by the then auto industry to create bodyworks.

In the 90s of the last century, these obstacles disappeared and the PDR began to spread over Europe and the United States.

With minimal time costs and costs of consumables, this technology gives a stunning effect. Therefore, it may be destined to replace the remaining ways to eliminate minor car body dents.

Essence of technology

The process of the careless removal of the dentin is that the technological holes of the machine under the body are introduced levers of various configurations. These levers managed by technician have pressure on the inside of the body. Also applied additional methods that "pull" dents outside. To do this, a special fungus is glued to the dent area. Pulling this fungus, the master aligns dents. The special glue used for this is removed from the car's surface, without leaving any traces.

When performing these works, there is no putty or richt. Such a technology allows you to restore the body to the original, factory type, completely removing all traces of dents, without resorting to painting a damaged area. Thus, the appearance of the car is completely restored.

The PDR technology can be applied to restore the geometry of the parts of the car body parts only when the dent has not resulted in damage to the factory paint and varnish coating. This is the only condition that allows you to make a care of the restoration of the geometry of the parts of the machine.

PDR due to the use of a smaller consumables than other repair technologies dents are a more advantageous way in terms of savings. In addition, a consumer repairs takes significantly less time than for repairs with painting. The small dent, left in an easily accessible place, can be corrected in just 15 minutes. Of course, this is the easiest case. But even the most difficult repair (large areas of dents, hard-to-reach places) on PRD technology will take no more than 2-4 hours. For motorists, this is a certain plus - it does not arise to part with its vehicle for a long time.




N.pDR technology tool

As for the cost, it decreases by about two times, compared with the price, which will be repaired with similar damage to traditional technology. Selection of the necessary paintwork and its use on the body - quite expensive pleasure. There are often the situation when the necessary paint is not in the service station. In these cases, sometimes you have to wait a few weeks until the necessary materials arrive.

In addition, this procedure requires replacement of the factory coating. And the presence of repainted parts in the design of the car significantly reduces the cost of the machine during its resale. Even if it turns out to be perfectly pick up the paint and the composition of the varnish, and the externally painted place will not stand out on the background of the entire body, there is a special device that determines the thickness of the paint coating that cannot be deceived. So repainting the damaged area in any case will be noticeable. This is another indispensable plus PDR technology for a car owner who needed to eliminate dents.

Also, PDR technology usually does not require dismantling the body parts of the car. Only in exceptional situations (when there is no physical ability to get to the damaged elements) such a need arises. The smaller probability of disabling the integrity of the factory assembly is another advantage of a robust removal of dents.

What is PDR technology?

How does equipment for removing dents without painting work?

Unfortunately, each owner of the car, even the most accurate, sooner or later faces such an obvious problem as a dent. It can be a dent from flying garbage on the road, from non-accurate parking, falling snow from the roof, or from such natural disasters as a hail. No matter! The fact remains a fact, there is a small dent, and I don't want to paint it in any way. Yes, and no money is asked for it, and dyeing the whole item ... In general, some disorders.

But technology is developing, including body repair. So imagine for a second that the dent can not be painted, but simply squeeze. Do not believe? Let me tell you the story of such an exciting technology to remove dents without painting called Paintless Dent Repair (PDR or Russian PDR).

History of the emergence of PDR technology

This story began in the 60s. Oscar Flyg and Enrichh Nyusla were employees of the Mercedes plant. During the regular exhibition, they repaired cars. which were damaged by visitors during the exhibition. Oscar Flaig squeezed out small dents of the hammer handle, preparing a car to paint, but he managed to do so jewelry that further painting was not required (up to this point all body defects demanded painting). It was one of the first cases of the application of this technology on the painted elements and became the starting point in its development.

Of course, at the moment the technology does not stand still and how the tools looked before and from what the technology is now two different things. So, what the technology looks like now and what systems it includes:

Hooks system

The first system that we meet is (the most obvious) hook system. When working with hooks, the straightening of dents occurs by impact on the defect on the inside of the part (extruding dents).

Adhesive system

Next, most popular among beginners self-painting deletion without painting is a glue system, one of the easiest. The glue system includes such components like glue, adapter, reverse hammer, miniylifer, reverse hammer and many other auxiliary tools. In this case, the straightening of dents occurs by impact on the part on the outside, in other words, gluing in a dent. One of the top tools in this system is cold glue, very popular among experienced masters.

SEATING SYSTEM

Of course, when extruding and pulling, dents can be faced with the fact that they appear bodies, peak pluses. The sedimentation system is designed to remove these unnecessary convexities. When hesitating, cores, stemmers, hammers for blending are actively used. The sedimentation system works by the attack of the Naskov, that is, the impact on the outside.

Blending

Blending is a sedimentation subsystem, an impact on a dent from the outside by the method of sedenting the Naskov at a distance, due to which the lifting of dents occurs.

Overvoltage system

The following system is a surge system. It includes ironers and countertops, or pillows for lifting. Works by implaccation by flashing on the tangent surface of the metal with the creation of the stop from the inside of the dent.

Accessories for PDR

For comfortable work, it is certainly not to do without the widest component - these are accessories. This includes such important and indispensable equipment as various links, tape winding, stops, tightening, screens, nozzles, plugs and much more.

Deval removal device without painting

An innovative solution when working with cars with a large zone of small damage, for example, as after hail, was the device induction effect on dent. The induction device of the THOT BOX Swiss production has proven itself as the most reliable and convenient in work. The principle of the inductance is in the magnetic head and the point heating of the metal, due to which dents are stretched. The main advantage when removing dents using the inductor is the absence of reinforcement work, since the impact on the defect is only on the outside of the part.

Lighting to remove dents using PDR technology

Well, last, but one of the most important components of a set to remove dents without painting is of course lighting. Why? Everything is very simple, if you do not see the defect, then you do not refill it. Currently, the German manufacturer of the company Nussle has been a breakthrough in the light direction, namely a six-band lamp with an innovative scatterer and thoughtful to the smallestly tripod and control system. With reliable and professional light, you will see and eliminate even the most insignificant defect.

The main advantage Technologies are the fact that the dent is removed without painting the part, and therefore, when resale, no one can see that you had a dent, the car does not go to the status of the bat.

Second important moment it Repair speed and its cost. On average, the repair of one dent takes 15-30 minutes, which is much faster even local painting. And the cost of repair is many times less, as practically no consumables.

No risks of color mismatch, Outputs and thick layer of putty.

Not required special boxesand a large place. One box is enough for the entire tool, and for repair.

Removal technology dents without painting - These are new features in body repair with a huge amount of benefits for both customers and masters.

Sooner or later, but even the most neat driver on the car will appear dents. What to do in this case is understandable. You need to drive the car to a hundred, leave there for several days and get the already denied Iron Horse.

But you can go and other way - faster, easy and cheap. What? Make it all yourself using PDR technology.

Pulling dent with PDR

Principle of technology

Initially, it should be noted that the PDR technology is applicable only if damage is shallow, and you can do without painting. To determine this, read the classification:

• shallow dents up to 5 millimeters, rounded shape, without metal chances and damage to the LCP;
• deep - from 5 to 10 millimeters, improper geometric shape, with metal chances and damage to the coating.

If mechanical damage on your machine can be attributed to the first group, the PDR method will save the situation.

Celers are fixed by car using special hooks. By pressing damage to the place of damage, the metal is straightened. The PDR set looks around this way:

The number of levers can reach up to 40 pieces and more. But such kits are already for professional auto repair shops.

In addition to special levers, a device is required in the form of a desk lamp. It is necessary in order to accurately determine the scale of dent and properly straighten the metal. In general, this work is independently easy.

Preparatory stage

Before starting repair work to remove dents without painting, you need to carefully inspect the damaged surface of the car. Do it better with bright lighting. Also during the diagnosis, carefully inspect the condition of the paint coating. If it is badly damaged, then the metal straightening using PDR technology will not work. In this case, you should use the classic method of Richtovka with the subsequent painting.

Also note that the PDR method is not applicable if Richtovka has already been produced in the field of mechanical damage, and a putty was used. During the work, she just fell off.

You can distinguish such factors in which the technology without painting is not applicable:

• if damage is more than 5 millimeters, and there are strong metal chances;
• damaged LKP;
• the car has an old trim;
• there is no possibility of working on the inside;
• previous work was carried out poorly.

In all other cases, this method can be safely applied in practice.

Elimination of dents by PDR

Richtovka process

First you need to provide free access to the inside of the machine. It is necessary to remove everything too much: the trim, mirrors, handles, etc. After the surface of the car is "free", you can start repair.

A special "lamp" is installed on the surface. As a rule, it is included:

Lamp with PDR set

Next, the lever of the optimal length is selected. Smooth gradual movements with the help of the selected lever, pressing the metal from the inner side in the dent area. It is necessary to do it very carefully and gradually, so as not to "pass" the metal. It is for this that a special lamp is installed. Thus, you can see a clearly surface of the car.

Schematically repair process can be displayed as follows:

Repair scheme

After the dent is "squeezed" up, the surface should be treated - make it perfectly smooth. This uses a special hammer and plastic cone. The damaged surface is cut. Thus, the metal is completely aligned.

If the scale of dents is large, it is better to carry out such a repair, alternating work with a lever and a hammer.

After the surface of the car is completely dedicated, and the dents will not remain, you need to spend the last repair work - put in order a car. This can be done on the principle of polishing the body.

Richtovka lever process

The final stage

For polishing after such a repair without painting, you will need:

• abrasive paste;
• small abrasive.

Through small abrasive, small defects are eliminated after leveling. And with the help of abrasive paste, the body is polished, the machine is returned by the original appearance. Thus, spending a minimum of time and money for repairs, you can put your vehicle with your own hands without painting.

Abrasive polishing body

Advantages of technology

In this case, it is possible without exaggerations to say that the PDR technology without painting does not have drawbacks. The only thing that can stop the car enthusiast is the price of a set of levers. But the cost of the PDR set completely pays for itself.

After an inaccurate parking on your car formed a dent? Or was there a hail and left damage to the roof? According to classical technology, spatlement is needed for alignment, and then the painting of the repaired part. And even at all replacing the tin item with an imminent subsequent color. Although in this case there is quite likely to reduce the price of the car in the secondary market, because Leave traces of repair. At least in the form of a thicker paintwork, which, in our time, is easily checked by a special device.

But you can repair PDR, and painting will not need. The advantages are obvious - the traces of repair will not remain, nor in the form of a thickened layer of paint (and putty), nor in the places of parts of the details. At the same time, the total time spent on the repair will be lower. After all, it is not necessary to expect a drying of painting materials. And you can use the car immediately after repairing "on the full coil." Because the mode of gentle operation is not required while the paint is fresh.

Essence of technology

The essence of PDR technology is to straighten damaged parts to the initial state, without the destruction of the paint layer. The technology itself looks quite simple - using a special tool, the deformation is simply fused back. But this apparent simplicity.

With glue

Although a number of so-called "clams" or dents outside inside out of bends and ribbies can rather straighten anything in the car. For this, special clips are used and various piston sized, which are glued with specialized glue to the conditional center of dents.

It is necessary to determine correctly and accurately - where to glue the piston. And this is not a geometric center of dents at all. It all depends on the stresses in the metal, and the ability to determine the right place comes only with experience.

Yes, and the character character itself requires not a small skill. After all, it is impossible to just pull the piston and return the original condition. A number of actions are required, jewelry quality. Otherwise, the pulmoned metal along the edges of the dent will be partitioned somewhat that it will not have a positive effect on aesthetics. Metal must "hold" along the way of obtaining dents in the opposite direction. Only in this case the traces will not remain. It is impossible to damage the paintwork, because otherwise the repair of dents on the PDR principle is no longer anything. Therefore, often, it seems to be a simple dent, straighten up into several techniques. But on the part, it all looks simple and akin to magic.

And at a successful completion, the glued piston needs to be removed. For this purpose, a special solvent is used, which affects only glue without affecting paint. The same solvent was washed off traces of glue.

Thermal recovery

Another option of repairing PDR some types of damage is a simple heating. Of course, in this way, it is possible to eliminate all kinds of damage, as a rule, these are ordinary dents with a small degree of deformation.

But the process itself is simple. After a specialist has established the ability to equalize dents in this way - the damaged place is simply heated by an industrial hairdryer. Metal, expanding on temperature and increasing its plasticity, restores the form itself.

However, here knowledge and experience are necessary for success, otherwise you can exacerbate the problem on the contrary. For example, if he is heated by a plot that is damaged more seriously and is not suitable for the recovery in a thermal manner, then additional damage to the boundary layer is made. It is more complicated to straighten.

Direct mechanical impact

Everything is not so simple here. This method is used when deforming the roiber of rigidity or bends of elements. Usually the impact is made from the inside, sometimes even with partial disassembly of the car.

From the first technology is distinguished by using a plurality of different devices, in the form of hooks and clubs. It can be combined with the adhesive method. The special tool is extruded from the inside to several receptions. Repeating the metal path in obtaining deformation, only in the opposite direction. Because Celers can be serious, and when restoring a form at the edges there may be a trace, then even "inflection" is used in the opposite direction, followed by a refund. This method achieves metal returns along the edges of dents to the initial state.

Of course, this procedure is already longer and requires sufficient effort from the Master. But still it is faster than classical technology.

Also, in some cases, pulling is used. This is characteristic when damage gained power elements with a complex form. Return them to the original form effectively precipitating.

What instruments will need?

For work on correction, dents for PDR technology will require special tools and a special room.

ABE instrument, where do not buy for a penny. For it, special alloys are used with high strength. Indeed, it is often a subtle twist, which prolazes into the processing hole, to conduct a significant effort. Yes, and the glue is used by the company, which is compatible with paint and varnish coatings used in the automotive industry, has high adhesion and can be easily removed using branded materials. Therefore, such a set is about 90 tr. Yes, and produce them only in the United States and Germany.

The repair room should also be specially equipped. After all, just a special contrast backlight with parallel lines will help to accurately see the relief of dents. According to their reflections in the area of \u200b\u200bdents you can accurately see the relief. In small areas, a fairly portable option, but for repair, for example, roofs, you need a backlight over the entire wall. Moreover, the contrast lines must be strictly parallel and equivalent on the observation point.

In addition, just to purchase tools and start producing repair with your own hands is unlikely to succeed. Own experience to comprehend the Aza technology will have a fairly long time, so that at least something began to get. Professional training is necessary. And it is worth it.

How to choose Masters

According to the reasons described above, the presence of special tools and trained master in the technical center does not give any guarantee of high-quality work. After all, a consuming experience is played here. The process of this repair is complicated, requires patience, many knowledge and experience.

Therefore, the main selection criterion is which master will produce work. It is reasonable to take advantage of the recommendations of friends and acquaintances that have already made repairs from any master. The rest of the exhortation is inappreciative.

In which cases is worth doing this repair?

The ability to restore the former form depends on the degree of damage. And both the metal and paint and varnish coating itself. Metal in a damaged place should not have breaks. Also, the attachment points (point welding or gluing) should not be damaged. If on the paintwork of damage, which cannot be eliminated by polishing - then the meaning in repairing the PDR principle is lost. Paint should not be damaged.

That is, ordinary dents on the roof or doors, or wings are not a problem, with a holistic paint condition. Of course, if they are not extensive and not fatal (metal whole). Such damage is corrected.

Another thing, if the blow came on bending, angle or butt of elements. It all depends on the nature of damage and is determined by the Master individually. In any case, a specialist before starting repair will explore all the damage and will lead the verdict - what can be corrected, and what will not work.

A serious obstacle is the deformation of the power cell of the car body, made of high-strength metal with an enlarged thickness. In some cases, these elements of recovery on such technology are not subject to. In this embodiment, it is necessary to apply classical repair methods. Therefore, recovery after a serious accident using PDR technology is unlikely.

But most of the small damage, with small contact accidents, internships in the parking lot or in the fall of items on the roof of the car are solved without problems. But it is precisely such damage, according to statistics, most. In addition, after such a repair, his traces does not remain. The car seemed never and did not receive damage, which positively affects the cost when selling.

Reasons for the appearance of dents on the car without damage to the paint and varnish coating: a rue of the elements, say, hail or storm, fallen from the roof of a neighboring house snow canopy or a mel At all adequate individuals.

Almost every car owner faced such damage, but not everyone knows that such damage can be easily repaired without resorting to standard body repair, followed by straightening and painting items. In general, everything and how we are used to.

Nine out of ten such damage can be quickly eliminated with the help of unique consumer Removal Technologies PDR dent (Paintless Dent Repair). The main condition for the implementation of such a repair is not a disturbed paintwork coating of the car body in a place of dents.

This technology was invented in Germany, at the Mercedes-Benz plant, in 1952 and is currently common both in Europe and in the United States. Finally, our craftsmen got to her!

To remove dents, small levers of different configuration and length are used. With their help, it turns out pressure on the inner part of the metal through the technological holes of the machine.

If it is impossible to get to dents from the reverse side of the iron, then special suckers are used (piston fungi), as well as special adhesive compositions and levers - called microlifers.

PDR technology itself

Under the example below, the photos and drawings will try to simply tell about the complex - one of the ways to remove dents without painting.

So, for straightening a simple dent, for example, on the hood, you need a hammer, a plastic cone, fit in the form of a kocherg, focus in the form of a wooden bar, a plate with contrast lines and of course a good light.

In the photo, it can be seen below how the master is out of the exemplary radius of dents and installed on the suction cup plate with contrast lines (black and yellow). It is needed for better control of the process when straightening, focusing on changing the reflection of these strips in the repair area.

By installing the "poker" to the emphasis and using it as a lever, the master begins to squeeze a dent upward.
Figure below shows that any dent has a formally similar to a volcano or crater, i.e. Not just a failure down, but the protrusions are formed.

Having squeezed a little to the top, it is necessary to cleanse its perimeter from above using a light hammer and a plastic cone that does not cause strong damage to paint and varnish coating.

Thus, acting alternately on the distance from the bottom, and then, taking it with its radius, as a result, we must achieve the perfectly smooth surface of the body part.

Having achieved the desired result, the traces remaining from repair should be removed, namely, to carry out work, which is usually done when polishing the body after painting.

To do this, you need a small abrasive, approximately P2000 and abrasive polishing paste. With grinding we remove small defects that have arisen after the kindling, and return the original brilliance of the body part.

In this video, you can watch one of the techniques of a specialist with PDR technology - repair with the help of "piston fungi".

Repair of the dentin case without painting is one only advantages in theoretically absolute absence of shortcomings. There is no need to leave your vehicle for several days in the workshop, the auto repair is performed quickly, the work takes, as a rule, from 30 minutes to 4 hours, in the most running cases.

In most cases, repair on this technology will cost several times cheaper than with typical body repair. The factory LCP is maintained on the vehicle, and your car does not automatically switch to the discharge "painted", and this can rather affect its price in the future.

However, there is one practical very significant disadvantage - this is of course the cost of tools and consumables for such a repair.

The price of the basic set is about 70-80 thousand rubles *. Approximate set, you can see in the picture below.

And this is a special adaptation, called microlift. With it, the pistons or fungi are glued to the surface of dents are pulled out the metal outward. In some cases, they resort to the help of a special reverse hammer.

But here, the folk craftsmen came up with how to save.
Maching from the subwoofers purchased in construction stores consumables and adjusions.

In general, if you decide to make small body repair with Consumer removal technologies PDR dents,you first should be familiar with the tools, which are very much, as well as the very technique of removing dents with these cunning fittings.

I consider this article as a familiarization. I think that this technology (PDR) of the body repair without damage to the paintwork will continue to develop.
