The welding process for plastic window profiles leaves behind welding beads that require mechanical removal. Using advanced CNC cleaning machines equipped with ultra-precise grooving or surface cut-off knives, manufacturers typically achieve one of four distinct groove types:

​

• Concise

• Recessed

• Protruding

• V-groove​
   

If you want to customise your groove appearance, we can engineer the ideal solution for your specific needs. Plus, we easily accommodate diverse machine setups from any manufacturer.
