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
Sandblasting Process
Sandblasting is the act of forcing solid particles of abrasive blasting material (such as sand) against a hard surface to smooth it or roughen it, remove paint or modify its surface characteristics. A sand blaster uses high pressure to accelerate dry silica particles to speeds fast enough to erode metal and other materials at a microscopic level. Sandblasting is commonly used to clean and prepare surfaces, but it can also be used to remove paint or create decorative effects on buildings, signage, boats etc.
There are several methods and tools that fall under the umbrella of sandblasting:
First and foremost, there is abrasive blasting. This method consists of propelling a stream of abrasive material via compressed air at a surface to smooth, roughen or otherwise modify it.
One of the most common alternatives to sandblasting is glass bead blasting or grit blasting. This method uses a stream of very small glass beads propelled by compressed air. The stream of beads impact the surface at high speed and scour it, removing dirt and other unwanted materials. Glass bead blasting is typically used for production work and therefore the glass beads are reused.
Sandblasting is also used in the preparation of surfaces prior to painting — such as removal of old paint or rust — or to roughen a smooth surface, such as concrete, so that sprays or rollers can apply a better bond. In this case, the lower part of the object, where it is less visible, can be "rough-blasted" with large abrasive particles to provide a key for the new paint or coating.
Sandblasting is frequently used as an art form of graffiti removal. Because sandblasting both removes material and imparts a unique finish to surfaces, much fine detail or intricate designs can be achieved in this way, often through the use of templates to guide the blasting.
