Plastic repairs judged below the surface
Nitrogen welding
We rebuild compatible cracked plastic with controlled heat and material.
Mountings inspected
We check the fixing points that keep bumpers and trims secure.
GRP capability
Suitable composite body sections can be rebuilt and refinished.
Repairing plastic rather than discarding it
A cracked bumper or split trim does not always need complete replacement. We repair suitable plastic vehicle parts affected by scrapes, cracks, splits and distortion, using the material and damage pattern to choose the method. Nitrogen plastic welding can rebuild compatible plastics by joining prepared edges with suitable repair material. We also carry out GRP repair on appropriate composite body sections. Before recommending plastic car repairs, we check the part type, missing areas, shape and mounting points because an intact surface means little if the component cannot be secured properly.
Strength and shape before surface finish
We clean the part and remove contamination before preparing the damaged edges. Cracks may need controlled opening, welding and reinforcement, while distorted sections can require reshaping before the surface is levelled. Mounting-point damage receives separate attention because it affects fit and stability. Once the repair is sound, we prepare and refinish visible surfaces to integrate them with the vehicle. Replacement is discussed when material loss, severe deformation or unsuitable plastic means a repair would not provide a dependable result.
Frequently asked questions
Can a cracked plastic bumper be welded?
Many compatible bumper plastics can be repaired with nitrogen welding, but we must identify the material and inspect the crack, distortion and mounting points. Heavy material loss or an unsuitable plastic may make replacement the safer practical route.
What is nitrogen plastic welding used for?
We use it to join and rebuild prepared areas of compatible thermoplastic components. Controlled hot nitrogen helps heat the repair zone and suitable filler material. The part still needs cleaning, edge preparation, reshaping and finishing around the weld.
Can you repair broken bumper mounting points?
Sometimes. We assess how much of the mounting remains, the load it carries and whether the surrounding plastic is sound. A repair must hold the component in the correct position; if that cannot be achieved reliably, we recommend replacement.
