FAQ
My machine shows a fault not covered in the troubleshooting tree.
Send the symptom, the material, the screw configuration and the last maintenance date. Photographs of the wear parts help more than photographs of the control panel. We answer most diagnostic enquiries the same week.
Do you provide on-site service outside China?
Yes — commissioning, FAT supervision and breakdown support. For wear parts, the maintenance schedule page lists what to keep on the shelf so a two-week lead time never stops the line.
