Automated Sealing Solutions for Corrosion Prevention


We enable a reliable and effective automation process.

Your Sealing Solution Provider

tesa sealing solutions help to prevent corrosion that can cause extensive damage to the car body.

We close holes in the car body securely with a lightweight and automated alternative to traditional rubber and plastic plugs. And we offer reactive tapes to seal panel joints and panel edges that are exposed to high physical stress and where conventional PVC reaches its limits. We allow a cosmetic sealing of welding seams in visible areas.


Hole Covering Automation – Products and Processes from One Source

In today’s automotive manufacturing, the car body can have more than 200 holes. To prevent water, dirt, and noise from getting inside the car, these holes have to be sealed securely.

Let’s look at how your individual application process can be designed to ensure a quick and reliable sealing of holes in the car body.

Stop Manual Work with Bad Ergonomics

By automating your hole covering application processes, unhealthy and monotonous production steps can be reduced to an absolute minimum.

This leads not only to an overall improved quality of work, but the risk of missing or misplacing a plug will also be removed.

Furthermore, an increased application speed enables you to reduce cycle time while improving overall sealing quality.
