How to repair plastic bamper,bamper tuning, of the car is necessary to protect expensive elements of the body from scratches, chips and other damage. It is able to take the impact in a collision at low speeds or while hitting a road obstacle. Bumpers at the dawn of the production of cars were made of metal, as well as other elements of the body, but over time the company abandoned this, preferring plastic. Car plastic repair, is not only functionally useful unit, but also a design element of the machine. That is why it must be maintained in good condition, and in this article we will look.How to repair plastic bamper,with their hands.
Bumper cars, which is called plastic, has a much more complex chemical structure than conventional plastic. It is flexible and maximally protected from external damage, which is important, given the operating environment of the unit. During the movement of the car on the highway or city road, crumbs fly off the bumper from the roadway-sand, stones, and other debris. In the first years of operation of the car these damages are imperceptible, but over time they make themselves felt, and the bumper loses its presentable appearance.

Especially dangerous is the second type of scratches, which can eventually move into the next phase of damage-a crack. Crack. Dangerous through damage of a,bumper,of the car at which its operation is not recommended. When the car is moving, vibration loads are transferred to the bumper, which will lead to an increase in the crack, which will affect the strength of the body part and its operational properties. Dents,cracked plastic car bamper. Repair plastic bumper cover.
Damage, most often caused by strong mechanical impact. Dents are often accompanied by cracks and always lead to scratches in the place of deformation.
Breakouts and chips. Through damage to a large area. Most often occur on the edges of the bumper in a collision with an obstacle at an “uncomfortable” angle. Chip paint without repainting whole bamper. Depending on the degree of damage, different methods of repair are used. Below we will look at ways to repair cracks and breakouts – the most dangerous types of damage. Before proceeding directly to the repair of the bumper, you will need to carry out a number of preparatory procedures: Remove the bumper from the car, as much as possible trying not to aggravate the damage. This is necessary to make it easier to work with the damaged area; Gently with water and a sponge (if necessary, with a cleaning agent), clean the,bamper to bamper,as much as possible from the stuck dirt and dust;
Cleaning the defective area. It is necessary to remove the paint and soil elements from the damaged area, both from the inside and from the outside of the,bamper.It is desirable to clean the paint surface within a radius of 1-2 centimeters from the damaged area; Determine the material from which the bumper is made.
Despite the fact that it is called a plastic part, it can be classified according to the class of material used.
Find the marking onthe inside of the,bamper tuning,and determine from it what quality plastic it is made of: ABS, PA, GF15, GF30: high-quality plastic, resistant to temperatures (Acrylonitrile styrene, polyamide, etc.); PUR: less durable polyurethane; PP, EPDM, PPT: low-cost materials polypropylene and ethylene diene. If the bumper is not marked, which would allow to determine the material, most likely it is made of fiberglass. Please note that when it comes to the base,bamper installed, at the factory, you can find out its material from the reference literature to the car or from the Internet. THE easiest way to self-repair a plastic bumper is using an electric soldering iron. This method of restoring the unit has a minus, which is expressed by the thinning of the part material in the area of damage during work.
You will need: strong staples from the furniture stapler, tape, standard electric soldering iron, drill, grinder with a circle P240. The order of execution of works: Prevent further propagation of a crack using a regular drill. Drill small diameter holes at the ends of the crack; then bring the damaged parts of the part together and tape them on the outside; then turn the bumper over and start working on the inside. Take a soldering iron and start to gently draw it along the crack, thereby reducing it; After several times with a soldering iron, you can begin to strengthen the connection with the help of furniture staples. To do this, take the brackets with tweezers, pre-shortening them if necessary, and hold them in place of melting the plastic,rear bamper protection pipe.
Since the metal of the brackets can begin to rust over time, it is recommended to completely cover it with plastic, soldering it from the area adjacent to the crack. Important: Always follow the thickness of the melting area, so as not to burn a hole in the,repair plastic bamper; When the inner side of the bamper will be soldered, do the same procedure with the front of the part, but without the use of staples, car interior plastic repair.
Next, you need to take a grinding machine with a circle P240 or manual grinding unit and begin to align the part,repair plastic car bumpers.
Attention: If the damage was on a difficult surface to align with the grinder, it is better to close up the remaining irregularities with putty for plastic parts than to thin the unit; If after working with the grinder there are “hairs” of the polymer, they can be removed with a lighter.
Please note that the procedure for repairing the bamper with an electric soldering iron is quite simple, but it is recommended to perform it together, especially at the stage of soldering the bracket, how to repair plastic bamper.
