Safety Mark

For cleats and 3mm thick sidewall:

Delay time: set it at 3s

Welding time: 50s

(u can adjust the time according to real case when the material is too thick or too thin,slowly by 5s interval )

Cooling time: 45s

Rise time: 3s

Counter: 0.5-0.6 for PVC cleats and sidewall 0.8-1.0 for PU cleats and sidewall.

Profile Moulds

HF machine need mould to finish welding work, regarding the mould, we list some normal size as you choose, and standard mould length is 500mm.
