Understanding Electrocoating And Its Functionality

By Essie Osborn


It is a painting process that needs electrical energy to deliver paint to a specified item. Electrocoating actually allows the production of some high quality products by manufacturers. This will please the many customers through long lasting items through the production of quality and attractive items.

The process is quite advantageous as it enhances the ability of a product to withstand corrosion for an extended period of time. The use of electricity to paint works due to the principle of opposites attracting each other. The process can be achieved by releasing a dc charge directly to a part that is metallic. The metallic part is then immersed into paint granules baths that are oppositely charged. As a result, the paint granules will shift towards the metal and attach themselves to it.

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.

Anodic and cathodic painting can be a success although it will highly depend on the type of charge that is going to be released and applied on the metal. The introduction of voltage to a positive element is referred to an anodic process. Here, however, the paint needs to be negatively charged to achieve the best outcome.

The whole process is composed of four main steps that are combined together. The first stage is called pretreatment step, as most manufacturers could describe it. Here, the metallic surface is cleansed and its surface adequately phosphate. The end product is usually one that is of high quality with a performance level that is quite exceptional.

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.
