Perforated metal spray process is divided into three steps:

First, pre treatment prior to punching a metal plate, rust, passivation treatment, in order to increase the spray layer adhesion.

Second,electrostatic spraying electrostatic adsorption principle, on the surface of the perforated plate of a uniform layer of powder spray coating.

Third,The high temperature curing coating good perforated plate is pushed into the curing oven and heated to a predetermined temperature (usually 185 degrees), and holding the corresponding time (15 minutes); remove the furnace was cooled to obtain the finished product.
