Powder Coating
Full Factory refurbishment process
Step 1
Removing the wheels from a vehicle
If we have the car on site it will be parked within our secure premises for the duration of the repair. The other option is that spare wheels are temporally fitted so that the car can stay on the road.
Step 2
Removing the tyres, weights & valves
The tyres are removed from the wheels and marked for precision & rotation, and tagged with the customer’s name. (If we spot unsafe tyres we will draw this to your attention. We reserve the right to refuse to refit tyres which are deemed to be unsafe.We then remove all balance weights, valves & sensors (if required).
Step 3
Stripping previous paintwork, grime & dirt
The wheel is then dipped in a special chemical solution to strip away the existing finish and break all dust. After a few hours , the entire wheel is fully stripped back to bare aluminium.
Step 4
Shot blasting - further cleaning of the wheel
The wheel is then sandblasted in a special blasting cabinet for more cleaning, corrosion removal and this also prepares the surface
Step 5
Wheel inspection
Once the wheel is fully cleaned it is much easier to see if there are any cracks or structural damage. The wheels are then tested on a balancing machine to check for any bends or buckles. At this stage , we will notify you if there is any damage to the wheel deemed to be dangerous, and advise if the wheel can be repaired and if any extra repair cost is involved.
Step 6
Structural repairs - straightening, welding (if required)
We have advanced techniques in the straightening of bent, buckled, dented or cracked alloy wheels. The refurbishment is not always necessary when straightening the wheel. If the damage is only small and on the inside of the rim, then we can repair just that area rather than the full refurbishment.
Step 7
Preparing kerbed surface for paint
The next step is selective machining to remove all kerb damage from the surface of the wheel (if the damage is very deep it can be filled with aluminium and welded to return it to its original shape.
Step 8
Painting the wheel
First, the wheel is placed into the oven for the preheating process. After this new powder primer is applied - After the powder is applied the wheels go back into the oven for the curing process. - After the curing process, the wheels are allowed to cool down slightly before the colour application and powder coat clear lacquer. -The wheels are then taken placed back into the oven to harden the coatings and ensure a full cure.
Step 9
Tyre fitting & balancing
Once the wheel is repaired we fit new rubber valves (if the wheels had metal valves or sensors these are re-fitted as before).
The tyre is then refitted to the wheel and balanced using weights stuck to the inside of the wheel.
Step 10
Fitting wheels to the car
The wheels are fitted to the car and final checks are carried out including tyre pressure and wheel bolt torque and tightening.
