What is plastic welding?

Plastic repair is growing in popularity due to the increased use of plastics in vehicle construction. There are a number of types of plastics commonly used that all have different properties and a range of repair methods. Here we will look at some of the methods commonly used and services we offer.


Adhesives are constantly improving and the need to join composite materials in the aerospace industry has seen high tech adhesives filtering down into the automotive market. In fact the McLaren MP-4 12C has a lot of important components joined to the chassis with adhesive and we are seeing increased use of adhesives for joining body panels in conventional vehicle construction. It is critical when using adhesives to use the correct product for the job.

Plastic Welding

Most plastics used in the automotive market are thermoforming, this means they can be reshaped and joined using heat. Much like welding metals plastic welding melts the surfaces to be joined and uses a filler of a similar material for extra re-enforcement. Done correctly this can be a very effective repair, done wrong it can be extremely weak. 

Hot Stapling 

We use a hot stapler system that adds extra re-enforcement to a panel prior to plastic welding. It is also extremely useful on areas that will come under load and need to flex such as brackets.
