Powder Coating Process
Powder coating is a multi-step surface finishing process suitable for metal and non-metal substrates. The method includes a preparation, application, and curing stage, and, at a minimum, utilizes a spray gun, spray booth, and curing oven.
In contrast to the liquid coating process, which utilizes a liquid coating suspension, powder coating is a dry finishing process which employs powdered coating material. During the process, the powder is applied to a substrate’s pre-treated surface, melted, and then dried and hardened into a protective/decorative coating. There are three stages: surface preparation, coating application, and heat curing.
The particularities and characteristics of the powder coating process’s curing stage are mainly determined by the method in which the dry powder is applied, as well as the type of powder coating material employed.
Once the powder coated part is cool enough to handle, the part can be, if necessary, assembled, packaged, and shipped.
Zinc Plating Process
(Electroplating)
Zinc plating (also known as Electroplating), is a process also known as galvanization, is the deposition of a thin layer of aluminum onto a metal component to provide a protective layer. The outer surface of the zinc coating oxidizes to form zinc oxide, which results in a matte silver-coloured finish.
Electroplating process starts with carefully cleaning the fastener surface in alkaline detergent type solutions. It is then treated with acid, in order to remove any rust or surface scales. Thorough cleanliness is essential as the molecular layers of oil or rust can prevent adhesion of the coating to the metal surface.
Electroplating is done by the process of electro deposition. The fasteners are dipped in a chemical bath containing dissolved zinc. When direct current is applied, the zinc metal at the anode begins to dissolve, and the free metalions reach the cathode to form a thin layer of coating on the fastener. The thickness of zinc plating depends on the time spent in the plating bath, the amount of electric current, and the chemical composition of bath
