TECHNICAL INFORMATION
Continuous painting process in convection oven
| ENTRY | The input accumulator, without stopping the oven procedure, staples one roll to another giving continuity to the process. |
| WASHER | The necessary cleaning is obtained to achieve an optimal adhesion. Eliminates the antioxidant or rolling oil that comes with the steel sheet, which allows to process a variety of materials regardless of the degree of cleanliness. |
| CHEMICAL TREATMENT | Chrome is applied with roll-coaters to form a uniform layer with good anchoring, which allows the primary paint to adhere to the chemical treatment layer. |
| PAINTER | It is used for the primary paint coat and for the finish coat. The first allows sufficient flexibility in subsequent processes of the sheet, in addition to helping to contain moisture, chemicals and salt from the environment, extending the life of the sheet. The finishing paint coat has excellent adhesion to the first coat of paint and allows the final appearance to be given to the sheet with the color that the customer requires, as well as the characteristics defined for the different applications of the final product. |
| CONVECTION OVEN | It consists of three sections to maintain and control different internal temperatures, thus achieving a controlled heating curve to cure the paint at the metal temperature defined by the paint supplier. Likewise, with its high-efficiency incinerator, it protects the environment from solvents. Once the paint is baked and cooled, material is re-coiled, depending on the customer's specifications. |
| EXIT | The painted material can be embossed just before forming the coil, or, that a layer of polyethylene (plastic) is applied to protect it in subsequent processes, in case the client specifies it. |
