KTT – Our services

Degreasing, LABS-free cleaning

Contaminants on the surface of the product - LABS in short - can cause defects during subsequent processing, such as painting, as they prevent the surface from being evenly covered. Such substances include silicones, fluorinated (PTFE) materials, certain oils and greases. For a material surface to be properly wetted by paint or adhesive, it must be clean, dry and free of oil and silicone. KTT's products are available in LABS free (LABS-frei) quality, which we provide with our own degreasing and cleaning equipment. We can even offer degreasing as a service, if the dimensions/material of the product allow it.

Contract manufacturing / outsourced production

KTT Sealing Technology, as a company specialising in the manufacture of custom rubber and metal-rubber products, primarily produces its products using its own production equipment and tools. However, it is also possible to manufacture using tools, equipment or material supplied by the customer. This ensures, for example, that previous product approvals can be maintained through a simplified notification process.

Our non-accredited measuring laboratory is equipped with, among other things, a modern 3D optical/tach measuring machine with a 400x400 mm stage for extremely precise measurements.
