For elastomers used in industrial applications, ttv offers a range of highquality surface finishings that ensure a reduction in the friction and wear of elastic components. Appropriate coatings are designed to prevent high levels of breakaway torque and stick-slip behaviour in dynamic applications in particular.
These coatings therefore ensure that dynamically loaded seals function in an even more economical and precise manner. Environmental factors are also taken into account, as only water-based finishes are used.
We carry out the finishing processes based precisely on our customers' specific requirements, including the option of using a coloured lubricant varnish to make the parts stand out.
Surface finishings lead to significant cost savings as a result of the following positive effects:

The automated coating of elastomers is a mass procedure with results that comply with Gaussian distribution. A crucial parameter for the process reliability and the monitoring of this reliability is the actual coating thickness, which is 3 to 9 µm at ttv.
There is currently no procedure that can measure the coating thickness on elastomers during the production process Light microscopy can only measure coating thicknesses of up to a few µ.
Procedures carried out on coated metal parts produce only unsatisfactory results when used on base bodies made from elastomer materials. Usable results are only achieved using cuttings measured with electron microscopes or cross sections on embedded samples.
Here at ttv, we carry out coating thickness measurements for you on the cross sections.
