My Current Primer Fails on Sharp Edges. What Is the Solution?
The tendency for liquid coatings to pull away from sharp edges, leaving a dangerously thin layer, is a well-known phenomenon called "edge pull." This is a major failure point for automotive components. The solution is the superior edge coverage provided by a cathodic automotive parts electrophoresis line. The electrodeposition process naturally builds a consistent film thickness, and specially formulated e-coat paints are designed to maintain this thickness even over sharp corners and edges. A TIMS automotive parts electrophoresis line is engineered to utilize these advanced coatings effectively, ensuring that your parts' most vulnerable areas receive the same robust protection as the flat surfaces.
What Do I Need to Become a Certified Tier 1 Coating Supplier?
Becoming a certified Tier 1 supplier requires more than just good parts; it requires a process that is repeatable, controllable, and verifiable. This is where a professional automotive parts electrophoresis line from TIMS becomes a critical asset. Our systems are designed to provide the rigorous process control that OEMs demand. We give you precise, digital command over every critical variable, from pre-treatment chemical concentrations to e-coat film thickness and cure oven temperatures. Crucially, our PLC systems log this data, providing the verifiable proof of compliance you need to pass stringent OEM audits and achieve top-tier supplier status.
How Can I Stop Field Failures from Corrosion on My Parts?
If you are experiencing costly warranty claims or field failures due to corrosion, it's a direct indication that your current coating process is inadequate. Surface rust on automotive components almost always originates in hard-to-reach areas like weld seams, flanges, and internal cavities where spray paint fails to provide coverage. TIMS solves this problem at its root with a automotive parts electrophoresis line. The immersion-based e-coating process uses an electric current to guarantee 100% coverage, creating a uniform, pinhole-free protective layer over the entire part. This total coverage is the only proven method to eliminate the starting points of corrosion and ensure your parts meet the long-term durability requirements of the automotive industry.
How to Ensure My Primer Adheres Perfectly to the Substrate?
Primer adhesion failure (delamination) is a catastrophic defect that often traces back to poor surface preparation. At TIMS, we believe that a world-class coating starts with world-class pre-treatment. That is why every automotive parts electrophoresis line we build includes a meticulously designed, multi-stage pre-treatment section. We engineer a series of cleaning, rinsing, and conversion coating stages (typically zinc phosphate for steel) that chemically and physically alter the part's surface to create an ideal anchor profile for the e-coat to bond with. This obsession with a perfect foundation is why parts from a TIMS automotive parts electrophoresis line exhibit superior adhesion and long-term durability.

Frequently Asked Question
Do you have any question?
Yes, a modern automotive parts electrophoresis line can be engineered to handle multiple substrates. This requires a sophisticated pre-treatment section with a flexible chemistry that can properly prepare both steel (typically with a zinc phosphate conversion coating) and aluminum (often with a zirconium-based conversion coating). A knowledgeable supplier like TIMS can design a multi-substrate line that allows you to process different parts with optimal adhesion and performance for each.
A vast array of components are processed through an automotive parts electrophoresis line. This includes structural parts like chassis frames, subframes, and cross-members; suspension components like control arms and springs; engine and transmission brackets; seat frames; brake components; and even entire bodies-in-white (BIW) at the OEM level. Essentially, any steel or aluminum part that requires a long-term, high-performance corrosion-resistant primer is a candidate.
OEMs like GM, Ford, Toyota, and VW have extremely strict specifications (e.g., GMW14671, WSS-M2P177) for corrosion protection. An advanced automotive parts electrophoresis line provides the process control needed to meet these standards repeatably. It allows for precise control over film thickness, cure temperature, and pre-treatment quality, all of which are critical parameters audited by OEMs. The ability to provide verifiable data from a well-managed line is often a prerequisite for becoming a certified Tier 1 supplier.
Cathodic e-coating (or CED) is the process where the part to be coated is made the cathode (negatively charged) in the electrical circuit. This is the universal standard for any high-performance automotive parts electrophoresis line. The cathodic process provides dramatically superior adhesion and corrosion resistance compared to the older anodic method, making it the only process that can meet the demanding salt spray and cyclic corrosion test requirements set by automotive OEMs.
Spray priming is a line-of-sight application, meaning it cannot reliably coat complex shapes, internal cavities, or recessed areas common in automotive components. An automotive parts electrophoresis line uses an immersion process where the electric field drives the coating into every crevice, weld seam, and box section. This "throw power" guarantees 100% coverage and a uniform film thickness, providing a complete, uninterrupted barrier against rust, which is something spray painting simply cannot achieve.
An automotive parts electrophoresis line is a sophisticated, multi-stage industrial system designed to apply a primer coating (e-coat) to vehicle components. The process involves submerging the parts in a liquid bath containing an emulsion of epoxy or acrylic resins and pigment. An electric current is passed through the bath, causing the coating particles to deposit uniformly onto every conductive surface of the part. This is followed by rinsing and baking in a curing oven to create a hard, durable, and highly corrosion-resistant finish.
