Vibrating table: what is it for and how it works
The uniformity and quality of the powder coating depends on several important factors: compliance with the rules for storing paint, preparing it for application, preparing the product for painting and the correct application of the coating.
In previous articles, we have already written about paint storage, surface preparation, and paint spraying technology. Now it’s time to prepare the paint for spraying. The vibrating table plays an important role at this stage. It sifts the paint, removing large particles, lumps and possible dirt from it. This is necessary in order to put into work the powder that was not applied to the product for the first time.
Reuse of paint saves significant costs on powder coating. All powder coating equipment works on the principle of recyclable paint. Therefore, despite the fact that the purchase of all the aggregates necessary for powder painting takes a considerable amount, as a result, the cost of applying such a coating is lower than a liquid one.
The principle of operation of the vibrating table
There are two types of vibrating tables: mechanical and automatic. In the production of vibrating tables, two types of this device were specially provided so that they could meet the different needs of customers.
In the first version, the paint is poured into the vibrating table by the painter. Plugs the device into a power outlet. After that, the rhythmic vibration of the metal mesh begins. The paint that has passed the mesh goes in a special reservoir. You can take powder from it and pour it into the pistol. Waste remains on top of the net that can be thrown away. Vibrating tables can work for a very long time without interruption. But to prolong the life of the equipment, it is better to pause it for 40 minutes every 4 hours. Although it is able to work twice longer without any interruptions.
With a constant supply of powder the reservoir with the paint fills completely within an hour. Anyone can use this device. You don’t need much experience to work with it. Before buying such a vibrating table, think about whether it is worth installing an automatic version.
The automatic vibrating table is built into the automatic line. For automatic powder feeding, it has a special cone at the top. When powder falls on the table, the lid clicks. Thus, the paint is protected from possible ingress of unwanted components into it. The paint is sifted in this vibrating sieve using air, which is fed into it under pressure. The sifted paint automatically goes into the compartment, from which the sprayers pick it up and reapply to the painting surface.
Some craftsmen try to make their own vibrating tables for sifting paint. There are a lot of links on the Internet to “video vibrating table” where you can see how to make a camera. However, such devices should not be expected to work properly and provide sufficient sieved paint quality.
Professional equipment will definitely meet all the necessary standards and production needs.
The device must be selected based on paint type and painting volumes. It is better to consult with specialists on this matter. Choosing a vibrating table, keep in mind that its price may vary. Basically, it all depends on the installed mesh inside.
