6.2 - PVDF Welding Table
PVDF DVS Welding Times For the Following Machines:
- Miniplast
- Maxiplast
- PM-125
- PM-160
* Cool down time in the clamps can be reduced by 50% provided the parts being welded
are not under duress until the complete cool down time has been achieved
D = Pipe & Fitting O.D.
S = Pipe & Fitting Wall Thickness
Temp = 210° C +/- 10°
PI = Initial Weld Pressure
P2 = Heat Soak Pressure
T2 = Heat Soak Time in Seconds
T3 = Change over Time in Seconds
T4 = Time to Bring up to Full Weld Pressure in seconds
P5 = Ending Weld Pressure
T5 = Cool Down Time in Minutes
