Bumper Repairs & Headlights by Advanced Auto Accident & Repair Ltd, Birmingham

On new vehicles plastic bumpers are now widely used, so repairing them requires a plastic welding technique; we specialise in this here at Advanced Auto using the latest equipment.

Hot Gas Welding

Sometimes can also be known as hot air welding, is a plastic welding technique using heat. A specially designed heat gun, called a hot air welder, produces a jet of hot air that softens both the parts to be joined and a plastic filler rod, all of which must be of the same or a very similar plastic.

Plastic Welding

Plastic welding is welding for semi-finished plastic materials, and is described in ISO 472 as a process of uniting softened surfaces of materials, generally with the aid of heat (except solvent welding). Welding of thermoplastics is accomplished in three sequential stages, namely surface preparation, application of heat and pressure, and cooling. Numerous welding methods have been developed for the joining of semi-finished plastic materials. Based on the mechanism of heat generation at the welding interface, welding methods for thermoplastics can be classified as external and internal heating methods.

Production of a good quality weld can not only depend on the welding methods, but also weldability of base materials. Therefore, the evaluation of weldability is of critical importance before welding operation for plastics.

A plastic welding rod, also known as a thermoplastic welding rod, is a rod with circular or triangular cross-section used to bind two pieces of plastic together. Only the highest quality of plastic welding rods are used to avoid porous voids in the repair

Freehand Welding

With freehand welding, the jet of hot air (or inert gas) from the welder is played on the weld area and the tip of the weld rod at the same time. As the rod softens, it is pushed into the joint and fuses to the parts. This process is slower than most others, but it can be used in almost any situation.

With the price of headlights and bumpers a repair can be a fraction of the cost of a new one, For example, a new front bumper for a Vauxhall Insignia is £453.00 plus paint and fitting, where as a typical repair could be as little as £210.00. A new Vauxhall Insignia headlight is MLP of £408.00, repair to headlight brackets start from as little as £60 so savings can be considerable.
