1 Products Description

              Ø  Main profiles: multi-chamber structure, separate drainage chamber;

Ø  This system can be connected through the couplings of *0°,**5°,**0°ordinary or enhanced and arbitrary angle;

Ø  Glazing beads are reasonably complete. Single glass, double and triple insulating glasses are varisized and can be installed;

Ø  Our upvc profiles are along with the gaskets, it cannot shrink and has better gas tightness.

2.3 Welding parameters and Considerations

Pvc welding of plastic doors and windows are five main process parameters, five process parameters and control range are as follows:

1. The welding margin :**4mm / single head (typically 3mm)
2. welding temperature: **5 °C ***2 °C (heating plate surface temperature)
3. Heating time: *5s**0s
4. Heating welding pressure :0.**0 .4 MPa
5. Welding pressure holding time: *2s**0s

The 5 parameters composed of a group, each parameter can be changed. According to a lot of practical experience, and generally fixed welding margin of 3mm, heating I welded a pressure of 0.4 MPa, welding packing time *0s.
