Kalotte – a strong profile for the future.
Our services
What we do?
We coat, perforate, profile and customize products for the construction of exhaust systems.
And in the form of domes with a wide range of dimensions. These are hollow forms that are driven into a metal sheet. Hence our name: simple and straightforward, but highly efficient – Kalotte AG.

Sound-absorbing heat protection
Our materials: micro-perforated and dimpled, partly heat-sealed foils and tapes made of stainless steel and aluminum. The benefit? Our products are used as sound-absorbing heat shields. And: the profiling that we do increases the rigidity.
Increase in rigidity
If the carrier material is profiled, its total surface area increases, which leads to greater inherent rigidity.
And where are our products used?
In the automotive industry, in the engine compartment, on and in the exhaust system, and wherever heat is generated. Kalotte products can also be found in the white goods industry, in energy storage, and in efficient heat and power generation.
Kalotte – a valuable player in the future, too.
Yesterday – today – tomorrow
And that is what makes us so valuable: our products are not dependent on any trends.
Whether combustion engine, electric motor or future technologies – our profiles fulfill their function in all devices. Reliable and high-quality.
Kalotte – a valuable player in the future, too.
Our process
Step 1
Coating
During coating, we melt the thermoplastic coating layer. This creates an adhesive bond between the substrate and the carrier film. The benefit? Together with the carrier sheet, a sound-absorbing heat shield is created, i.e. an acoustically and thermally effective insulation layer. On the side facing away from the sound source, there is a protective film with micro-perforations.
Step 2
Micropunching / perforation
In further steps, the carrier materials (heat-seal film, stainless steel, aluminum, steel) are perforated in the micro range of 0.1 – 1 mm, after which profiling is carried out. The universal product then enters the process defined by the customer. After delivery to the customer, the customer can go directly into production to complete the exhaust system or parts of it. Important cost-intensive process steps are outsourced to us.
