Improved Transfer Efficiency Through Powder Equipment Design

摘要

Improving transfer is a hot topic that is only getting hotter. First-pass efficiency has long been a top priority for those powder coating operations trying to maximize their profits and produce better parts. But with today's soaring energy costs and the increased awareness of the environmental impact of wasted energy, the idea of generating greenhouse gases solely to spray powder that falls on the spray booth floor is less acceptable than ever. The idea of transfer efficiency is a simple one: put all of the powder on the part. In practice, however, it is much more complex. It is not a matter of just putting powder on the part, but coating the part uniformly, and at the optimum film thickness needed to achieve certain functional or aesthetic properties (like corrosion resistance or opacity). It does no good to just pile up powder on one edge and leave exposed bare metal on another.
