In order for the paint to be adequately deposited, this process is used. Electrocoating is a process that gives rise to some beautiful products which are of high quality as well. For the paint to be successfully deposited, the use of electrical energy is applied.
The process is very beneficial because a product is able to tolerate corrosion for longer lengths of time as compared to those that have not undergone through the process. The main principle of “opposites attract” is the main element of this whole process. A dc charge is usually released to a metallic part. Immersion of the metallic part into paint granules baths that have opposite charges. The metal attracts the paint particles which attach on to the metal.
The painting process may take a considerable amount of time, although there are quite a number of factors act a determinant factors on the amount of time that the whole process should take. The speed at which the paint is deposited will be highly dependent on the supply of power that is released to. Additionally, the optimum speed of painting can be determined by the machine model that is in use. Of importance to note is that the paint’s thickness will also be able to influence the duration of the whole process.
Depending on the kind of charge that is applied on the metal, anodic or cathodic painting can be achieved. Anodic process is as a result of voltage being introduced to a positive element and negative if introduced to a negative element. In this instance however, the paint should be negatively charged.
A combination of four different steps makes up the whole process. Pretreatment is the first step. In this step, the metallic surface undergoes cleansing and phosphate too. High quality products are the end products that can be expected from the procedure.
A standard bath is required for the metal where it is bathed in paint solids and water that has been ionized. These are the main components of a bath that is considered standard. The particles are allowed to move through water. Resin and pigments are the main components where resin is usually used to enhance a product’s durability; pigment is mainly used for achieving the color that is desired.
Post rinsing is then done after the element has been painted. The process involves rinsing out of the paint that got attached to the component. The paint is directed back to the tank. The items appearance will now appear stunning as the process is considered a success.
After going through rinsing, they are taken into a bake oven. The temperature within the bake oven is quite high, which enables the layer of paint to dry up well. When the whole process is complete, the client is able to receive their goods in a carefully packaged delivery.
