Dacromet coating process steps

Posted on 2018-07-24
In the surface processing of products, the application of Dacromet treatment process is very common, especially for metal parts. After its treatment, the oxidation resistance and corrosion resistance are obviously improved. So how do various standard parts perform Dacromet coating? How do the specific process steps unfold?


1. For standard parts such as bolts, nuts, washers, etc., the workpiece can be placed in a frame or basket, immersed in a Dacromet tank, and then transferred to a sputum machine to centrifuge the surface of the workpiece with centrifugal force. When it is dropped, the coating on the working surface is even and thin, and there is no liquid in the groove.


2. For workpieces with high requirements on the appearance quality, the workpiece can be placed on a hanger and then coated by electrostatic spraying.


3. For those large workpieces, the workpiece can be immersed in the coating tank, and then the excess coating on the surface of the workpiece is blown off with an air knife to make the coating uniform.
