Powder-pattern control - use the right tool for the job
Tools are most effective when they're used for tasks they are best suited to. The tools that direct and control the flow of powder as it leaves the tip of the application gun are no exception. It is as difficult to powder coat a part well with the wrong pattern-control device as it is to install a screw with a hammer.
Application-equipment manufacturers have designed a variety of pattern-control devices, each for a specific purpose. When end users employ them for jobs they can't perform, the result is poor coverage and low transfer efficiency. The information this article presents about the correct use of pattern-control devices will help readers overcome these problems.
