Car bumper repair and car body plastic parts repair has become a very frequent need thanks to the quality welding improvement of all related technologies, practical advantages and huge cost savings if compared to replacement guaranteed by this type of repair and the ecological need to recycle plastic to meet the general Environmental care.
Plastic welding for car body repair allows today to repair cuts, holes as well as supports and buttonholes so to fully regenerate the damaged parts. This procedure consists in welding by using nitrogen so avoiding premature aging and providing optimal plastic resistance features.
Based on our 42 years wide experience, MWM has recently updated its product range for plastic repair by bringing many improvements aiming to grant highest compactness without limiting the flexibility and plastic welding quality.
In this section of our website we show how to repair a car bumper, more precisely how to rebuild a bumper’s eyelet with MWM Plastic Welders and the technique of plastic welding.
REBUILDING OF A FIXING EYELET OR SUPPORT OF A BUMPER - VIDEO LINK
Clean the bumper damaged area with the cutter (code 31815) scraping away any paint rest so not to pollute the new plastic when melting.
Before starting plastic welding, take the aluminium plates and the clamps (code 31880) and fix them below the area where the plastic strips will be melted and the bumper support will be rebuilt.
Use one of the various MWM plastic welders, choosing between Nitrogen plastic welding or Compressed Air plastic welding.
Heat with the heating gun the area on which the plastic strip will be welded; move slowly with the tip of the heating gun following the plastic strip until the damage on the bumper is fully covered. Check correct grip, including the edges, and check that plastic strips is perfectly welded to plastic bumper.
Weld any further plastic strip to do the finishing and after that use the roller to smooth it out, squeeze air microbubbles which might have been created during the welding and finish.
Repeat the same sequence of operations on both bumper sides to achieve a higher strength and resistance of the repaired part after the repair is made. Press with the clamp after uniformly heating up the material welded.
To optimize bumper holder rebuilding, use the roller to smooth out and furtherly finish with fine sandpaper or glass-paper the surface of the welded part.
