The pretreatment stage is the foundation of a durable enamel finish, and on a TIMS enamel production line, it is a seamlessly integrated part of the system. We don't just add a washer at the front; we engineer it as part of the continuous flow. The conveyor speed is precisely calculated to ensure each part receives the exact required immersion time in each chemical stage. The control system for the pretreatment section is part of the line's central brain, allowing for automated monitoring and dosing of chemicals. I have seen many lines fail because the pretreatment was treated as an afterthought. On a TIMS enamel production line, it is treated as the critical, foundational first step to a perfect finish.
