Release agent application and finishing with powdery substances

The task

Separating layers or producing specific properties

Some composite applications require the separation of individual layers or obtaining certain properties by applying powdery substances. For example, to impregnate or to apply flame protection. The task is to obtain the function required for a particular use through the precision-metered application of powder or a powdery substance.

The release agent application

A very finely metered powder application represents a good choice of creating a thin separating layer.

Finishing with powdery substances

The application of powder-type materials, such as encapsulated substances impregnating the composites, rendering them inflammable or easier to shape or making them more stable can impact the desired type and features of composites.

Antistatic through powder application

Moving film or sheets from synthetic fibres tend to become statically charged. The application of a very thin powder layer can improve many processes.


The solution

Exactly metered application of powdery substances

WEKO-Powder-Application-System (WPA) such as WEKO-AP or WEKO-ESC provide many choices for the production of composites. Even at top speeds and the associated dynamic processes, WPA work with high precision and reliability because of their highly efficient application nozzles. This reduces the required application quantity as well as soiling of the plants and provides maximum quality.

The realisation

Composites need WEKO-AP or WEKO-ESC

The powder systems WEKO-AP and WEKO-ESC are specifically engineered for the high demands of advanced machines for the production of composites. They have been designed specifically for the preparation of a powder-air mixture and an accurately reproducible and extremely uniform powder application. Several compact systems with widths up to four metres are available for you to choose from. In addition, the WEKO-AP200 and WEKO-AP300 offer the VARIOBOX® System for quick powder change.
