                                      Infrared thickness detection                  

 

Huakai group is a pioneer in the PVB industry by using lower layer thickness control to monitor the film thickness after extrusion. The thickness scanner keeps track of the PVB thickness for 24 hours to ensure that the PVB film thickness is within tolerance. This consistency of thickness is the key to minimizing glass defects during lamination.
