Release agent application

Release agents prevent the material from sticking to the press belt and ensure uninterrupted board production.

A controlled and uniform moistening of the top layer of the fiber, particle or chip cake evaporates due to the heat of the press. This steam shock effect activates the adhesive up to 30% faster and thus reduces the correspondingly required pressing time.
This enables higher production speeds.
The precise application of moisture also leads to higher board density (strength), the surface becomes more uniform and, as a result, fewer grinding operations and material removal are necessary.

The decisive factors in moisture and release agent application are uniform application to avoid optical imperfections. This is because a poorer surface appearance must be sanded down again afterwards. Alternative spray application systems sometimes have cloudy and streaky application patterns and vary the application quality, especially at different speeds.

WEKO offers your customers a unique solution by contactless rotor dampening.
The supply unit WEKO-FlowTec and the highly efficient rotors of the WEKO-Sigma ensure an even application of fluids to the mat and the mold base (belt) at a wide range of speeds. The application quantity is simply entered on the touch display, as is the release agent metering quantity.
An optional automatic height adjustment ensures optimum distance to the surface even with different mat thicknesses.
