Doublefacer Gun Drilled Hot Plates

Upgrade Application

Applicable to most doublefacers.

Upgrade Description

Gun drilled hot plates replace existing hot plates to permit more effective heat transfer, while maintaining a higher surface temperature. This increased surface temperature minimizes plate deflection and edge crush. Board quality also improves from this temperature increase. MarquipWardUnited will provide standard 25 mm (1 in) steam inlet and outlet. Customer is responsible for steam piping and installation.

An Infusion-Capable hot plate option adds InfusionTM steam passages to provide even greater process control in the doublefacer.
