When investing in an oven enamel production line, there are critical features to demand. 1. A Two-Coat, Two-Fire System: Insist on a line designed for both a ground coat and a cover coat for maximum durability. 2. Robotic Application: Look for advanced robotic systems with lance-movers capable of reaching all interior corners of the cavity. 3. High-Performance Furnace: The furnace must guarantee exceptional temperature uniformity (±5°C) for a consistent cure. 4. Integrated Process Control: Demand a single, centralized control system that synchronizes the entire line. 5. Turnkey Provider: Choose a partner like TIMS COATING who can design, build, and commission the entire oven enamel production line as a single, integrated project.

Enamel chipping inside an oven is a serious quality failure, usually caused by poor adhesion that cannot withstand the stress of constant heat cycling. This is prevented with a high-quality oven enamel production line that perfects two key stages. First is meticulous pretreatment. A rigorous cleaning and etching process creates a microscopic anchor profile for the enamel to grip. The second is the application of a dedicated ground coat. This special layer acts as a flexible, high-adhesion interface between the steel and the top coat. A TIMS COATING oven enamel production line ensures both of these foundational steps are perfectly controlled, creating a powerful, lasting bond that eliminates chipping.

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.

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.
