Within the manufacturing industry, powder paint has reached high levels of popularity. The reasons behind this are quite simple; it provides a highly durable industrial finish, its application is efficient, resources can be better used, and it is environmentally friendly.
When you have a high need for production and parts that can be grouped by shape and volume, the best solution is to adopt a continuous paint line. These lines can only consist of a booth and a curing oven, with a chain that carries the pieces to be painted between both teams; or they can also include a pre-treatment system, drying, cabin, oven, and other additional ones such as automated loading/unloading, as well as different options for painting and curing depending on the parts to be treated.
The case that we will talk about today consists of a continuous line with a cleaning process in five stages, a combined oven for drying and curing the parts, a painting booth, and an overhead conveyor.
This line, located in an important manufacturing company from the electricity sector in the State of Mexico, was developed to fulfill the client's need to stop depending on external suppliers for the powder painting service. Since their materials could be easily arranged in racks, it was decided to use a continuous line solution that included a five-stage washing, drying, powder painting, and baking.
Different things were considered for the determination of the washing process; the UL quality requirement that the equipment produced by this company had, the requirements exposed by its customers and the supplier of the process chemicals. In this way, in five stages, it was possible to obtain up to a thousand hours of resistance in a saline chamber.
The design of the dual-purpose oven was born from the need to make efficient use of space, given that the line would be assembled in an existing plant and only had the possibility of relocating a limited amount of equipment.
This line has a single paint booth equipped with a cyclone and a dust collector. This arrangement allows you to paint the main color and recover approximately 90% of the paint (actual amounts) before doing a color change. As it has a cyclone for dust separation, it is not necessary to change the filter cartridges in the cabin. This cabin has two positions for its operators. The paint booth, the cyclone separator, and the dust collector are GTM's own designs.
The curing oven, as mentioned before, results from taking advantage of the heat in this area to heat the drying step. In this way, there is a single combustion chamber, the non-adiabatic dividing wall between both areas allows the calorific power of the burners located at both ends of the equipment to be used to the maximum.
As well as lines made previously, this example is one of our success stories with turnkey equipment. We will gladly develop your project together with your requirements, suppliers, and growth forecasts.
