A Custom-Designed Line for Your Unique Oven Models.

This is a common misconception. A thicker enamel coat is not necessarily better and can actually be worse. If the enamel is applied too thickly on an oven enamel production line, it can create its own internal stresses during firing and cooling, making it more prone to chipping and cracking under thermal shock. The goal is not thickness, but uniformity at the optimal thickness. A high-performance oven enamel production line from TIMS uses robotic applicators and precise process controls to apply the enamel at the exact thickness specified by the frit manufacturer (often surprisingly thin) to achieve the perfect balance of flexibility and durability.

Sharp edges and rack-support embossments inside an oven cavity are common points of failure for corrosion. A simple spray process often leaves these edges with a very thin, vulnerable layer of coating. A modern oven enamel production line solves this problem using electrostatic applicators. As the enamel is sprayed, the electrically charged particles are naturally drawn to the nearest grounded metal surface, which includes sharp edges. This "wrap-around" effect causes a thicker, more protective layer of enamel to build up on the edges. A well-engineered oven enamel production line from TIMS is designed to maximize this effect, ensuring even the most difficult areas of the cavity are fully protected.

Color inconsistency in oven interiors (e.g., one side looking a slightly different shade) is a quality control issue that originates on the oven enamel production line. The two primary causes are inconsistent application thickness and uneven furnace temperatures. If a robot applies a thicker layer of enamel in one area, it will fire to a deeper, darker color. Similarly, if one part of the furnace is 10 degrees hotter than another, it will also alter the final color. A TIMS COATING oven enamel production line solves this by using precisely programmed robots for absolute application consistency and by engineering our furnaces for exceptional temperature uniformity (±5°C), guaranteeing a perfect, even color throughout the entire oven cavity.

The process performed on an oven enamel production line is a precise, multi-stage sequence. It begins with deep-drawing the steel sheet into the box shape of an oven cavity. This cavity is then loaded onto the line and enters a 1. Pretreatment section to be thoroughly cleaned and etched. 2. Ground Coat Application: A cobalt-rich base coat is applied, typically via robotic spraying. 3. Firing: The cavity is fired in a furnace at ~850°C to fuse the ground coat to the steel. 4. Cover Coat Application: After cooling, the final colored (e.g., blue or black) cover coat is applied. 5. Second Firing: The cavity is fired again to fuse the cover coat, creating the final smooth, durable surface. This complete process is automated on a TIMS COATING oven enamel production line.
