The parts are gently cleaned in the pyrolysis furnace. Afterwards they are carefully cooled in a controlled cooling chamber.

3. Electronic function control
The heating elements and electronic components are checked for functionality and replaced if necessary.

4. Manual cleaning
Chalk residues are removed with compressed air and the individual components plus all accessories are mechanically cleaned.

5. Polishing
All cleaned components are polished by hand and visually inspected for damage. A chemical inspection checks the condition of the coating.

6. Assembly, measurement & documentation
The die will be remounted and all wearing parts replaced. Defective components are repaired or replaced if necessary. All modules are measured and optimally adjusted. Finally, we hand out the overworked die head together with a documentation including detailed pictures of the full service.
