Why To Measure The Coating Thickness?

Coating thickness is one of the most essential aspects to determine the quality of the product and to maintain cost control. In every coating procedure, it is very important to make the right choice of equipment for its measurement. A proper coating procedure includes the measurement of its type, size and shape of the part, its thickness and the substrate material.

It is the thickness of the materials that determines its quality and lead buyers to get from its manufacturers. The device used for measuring the thickness of objects like aluminum, brass or copper is coating thickness gauge. This device has been extensively used in the present days by the large number of the industries because it provides surface finishing to the product and makes it appealing. Excessive thickness in paint always leads the coating to become dry while on the other hand inadequate amount of paint is not enough to cover the object properly. Considering this reason, a thickness measuring device is developed with the purpose to save costs. There are different types of gauges available, which provide desired results in terms of thickness. These tools successfully complete any project as the way it measure the thickness of the coat is accurate in quantity. Not only the object, but many car manufacturers also using this device to have full control on the quality as well as the quantity.

From all the devices, some of them also magnets which are generally very cheaper and simple to use. They signify the thickness on the basis of pull-off force in which the paints that are thicker pass low magnetic reaction while thinner paints pass strong magnetic reactions. To get the thickness results in non-metallic surfaces, gets support from pulse-echo technology in device. In this process, electric signals are passed through the coat which in turn, help to determine the thickness. Since years, such devices are being used to acquire the right amount of thickness and to satisfy each and every customer. There are basically three types of gauges to measure thickness and they are wet film thickness, powder film thickness and dry film thickness. Among all these, dry film thickness plays a crucial part in the coating industry. It is measured either on magnetic or non-magnetic surfaces.

Coating surely involves cost, but its absence can turn this cost into expenses. Its thickness cannot be measured directly, but need the main parts of ultrasonic elcometer. This include the host and the transducer. The host display the counted circuit while the transducer transmits sound waves. It measures many samples during the production very easily in a really quick and easy manner.
