Today's vehicles have many different types of fuel-saving materials such as lightweight alloys and plastics. It is important for the auto body shop to be aware of different materials and techniques used for their elimination.
auto body shops and collision repair services to refer to the instruction manuals for the repair of the bumper. different materials require different types of finish materials, removal and installation procedures.
Bumper Repair
When the plastic bumper cracked or has a small hole can be repaired to look like new. Replacing the bumper is wasteful and create unnecessary residues in our landfills. good, eco-friendly auto body shop just would recommend replacing the bumper if the damage is severe enough that the repair time would be considered unreasonable and the quality of results will be unsatisfactory.
the cost to repair small scratches, cracks and holes in the plastic bumper is often much cheaper than replacing parts. Of course, many collision repair technicians prefer to replace the part and charge a fee for the plus mark-up in price partly because they lack the skills of cosmetic repair and it is easier to guarantee the work.
Working with Plastic
the first step to repairing plastic bumpers is to identify materials in order to choose the method of repair. Auto Body shops use ISO codes for identification of parts for different families of plastics. They cross-reference codes with a map of the suppliers or access reference materials on the Internet.
It is important that the collision repair technician determine the type of plastic they are working with, so they know the proper welding procedure to use to avoid damage to parts.
some plastics can be welded with airless welder or a hot air welder, others require a hot glue type of procedure. Tests should be performed and welding procedures must be done properly to avoid the failure of adhesion. Some bumpers will dissolve with little change in color and they will remain sticky in the area where they are melted.
Repair Adhesives
bumper repair technician must identify the type of plastic work with in order to be successful with glue repair. The failure properly to identify the plastic results in adhesion-related problems.
flexibility
Some repair materials based on flexible and rigid plastics. Using the wrong material can cause cracking when the part is bent or can not provide the exact strength of the repair area.
Cleaning and Prep
Proper cleaning and preparation is critical for proper fit and finish. There is a technician repair or replace the bumper, some will need to be cleaned. bumper repaired is likely to be dirty from the road, the new replacement part may have contamination in the manufacturing process
.auto body repair professionals should use low VOC cleaning or special surface of plastic parts for cleaning to prevent solvent going too deeply into the plastic. If the solvents are too harsh, go deep into the plastic and cause adhesion problems after the repairs are done.
This is an overview of the process of working with plastic. Time is money in the auto body industry, therefore, many collision repair technicians decide to replace rather than repair of plastic bumpers and other parts of the
.technology allows us to fix many things that are often replaced. As resources become more scarce and landfills become over-full, we really need to be considered for repair rather than replacement when possible.
