Pre-fluxing using Binder-Based Spray Method

Purpose

To pre-flux sample parts – either on the complete surface or selected surface areas. Different types of flux and binder mixtures can be used. Manual and semi-automated pre-fluxing is possible. Optimal binder and mixture compositions for customer specific parts and brazing configurations can be evaluated.

Procedure

The components are pre-fluxed using manual or semi-automatic equipment which ensures uniform coating and control of the load. By changing the rpm of the rotating table the spraying time for the parts can be varied, thus changing the paint load. Constant rpm and the fixed setting of the spray gun ensure repeatability during testing. The design of the equipment makes it possible to paint large quantities of parts, even up to a few hundred per working day.
