Producing a powder coating is
a multi-step process. It can be
described as being semi-continuous
because it begins as a batch
process (weighing and pre-mixing)
but evolves into a continuous process
(extrusion and milling). In the last
Technology Interchange article, we
discussed the first steps in manufacturing
a powder coating. This consists
of weighing, premixing and extrusion.
This edition covers what happens
to the flakes generated from the
extrusion process.
