[MW:27285] Welding of uPVC Profiles

Dear Experts,

I am welding uPVC profiles (Thickness 2-3 mm and width 65-70mm) for making doors & windows and after welding at corner joints, the joints are getting cracked at the corner.

The parameters which we are currently following are as follows:

Temp: 245+,- 5deg C

Welding Time: 30 sec

Heating time: 30 sec

Welding Pressure: 6 Bar

Clamping Pressure: 4.5bar

Please advice to join the crack free weld.

Thank you in advance.
