HMW Härterei Michael Welser

Pre- and post-treatment

Pre- and post-treatment

To eliminate unacceptable surface layers, we rely on blasting processes. Our multi-stage cleaning systems guarantee the best possible surface preparation for the new coating.

If additional pre- or post-treatment is required, HMW can choose from a wide range of technologies – the most appropriate for this application. If e.g. Residual material in difficult accessible areas must be removed, the high-pressure steam cleaning or degassing in vacuum systems is used.


Loyal HMW partners know that we use the Christmas holidays every year to carry out maintenance and repair work.
We will therefore be closed again this year from 23.12.2023 to 01.01.2024.

Neither collections nor deliveries are possible during this period.
Last delivery: 22.12.2023

We will be back for you on 02.01.2024.
