A Complete Production System from a Single Expert Partner.

This is a common and dangerous myth. The final quality of a part is directly dependent on the engineering and process control capabilities of the electrophoresis production line. A lower-cost line might have inconsistent heating in its oven, poor circulation in its E-coat tank, or manual chemical dosing, all of which lead to variations in finish quality and durability. A high-performance line from TIMS features intelligent sensor feedback, automated process control, and advanced designs for components like anode cells and curing ovens. It is this commitment to precision engineering that ensures a TIMS electrophoresis production line delivers a consistently superior finish with maximum uptime and reliability.

If your current finishing process is a bottleneck, replacing it with a modern electrophoresis production line can provide a dramatic leap in efficiency. Unlike manual spray processes that are limited by operator speed, an automated E-coat line runs at a consistent, optimized pace. The process is highly repeatable, which nearly eliminates the need for time-consuming rework. Furthermore, a well-designed line from TIMS integrates all stages seamlessly, eliminating dead time between processes. Features like high-efficiency ovens and automated chemical dosing also reduce energy and material consumption, making the entire operation more cost-efficient and increasing the overall throughput of your facility.

The process flow of an electrophoresis production line is a highly controlled, sequential journey. It begins with loading parts onto a conveyor system. The parts then enter a multi-stage pretreatment tunnel, where they are sprayed or dipped in a series of cleaning, rinsing, and conversion coating tanks. After pretreatment, they enter the main E-coat tank, where they are submerged and electrically charged to deposit the paint. Following deposition, the parts go through several post-rinse stages to recover excess paint and ensure a clean surface. Finally, they travel through a large curing oven, where the coating is baked at high temperatures to cross-link and harden into its final durable film, before being unloaded from the line.

"Drag-out" is a term used in an electrophoresis production line to describe the liquid paint that clings to a part as it exits the main E-coat tank. This represents a significant loss of expensive paint material if not managed properly. A TIMS line minimizes and recovers drag-out in several ways. First, we design part racking and tilting mechanisms to help the paint drain back into the tank. Second, the part immediately enters a series of post-rinse tanks. These rinses wash off the remaining drag-out. This rinse water is then sent to an ultrafiltration system that separates the paint solids and returns them to the main tank, creating a closed-loop system that ensures nearly 100% of the paint is utilized.
