- [Defect control in matte finishes: achieving Primer Coat success](https://j3dvision.com/en/matte-paint-defect-control-primer-coat/): In the car body painting process, the Primer Coat (primer surfacer) is a critical stage: it determines the leveling, adhesion, and aesthetic outcome of all subsequent layers. Unlike the final finish (Top Coat/Clear Coat), primer typically features low gloss and a texture that complicates visual inspection and reduces the performance of conventional machine vision. A common plant approach is to intensify inspection during the Top Coat phase. However, many defects originating in the primer—such as pinholes, craters, lack of coverage, or contamination—can propagate, affecting the final finish and leading to costly rework. The most efficient strategy is not «detection at […]
- [Underbody Inspection: preventing assembly errors in automotive manufacturing](https://j3dvision.com/en/underbody-inspection-preventing-assembly-errors/): In the automotive industry, many of the most critical issues remain invisible… until the vehicle is already on the road. The Underbody is home to elements vital for a vehicle’s safety, durability, and watertightness. A minor error in this area can manifest months later as cabin noise, water leaks, corrosion, or even structural failure. Historically, Underbody Inspection has been one of the most challenging phases of automotive quality control. Restricted access, irregular geometries, poor lighting, and unreliable manual processes have allowed far too many defects to slip through the cracks. Today, automated Underbody Inspection is no longer an optional upgrade. […]
- [ELPO Coating Inspection: Anti-Corrosion Protection in Automotive Manufacturing](https://j3dvision.com/en/elpo-coating-inspection-automotive/): In automotive manufacturing, corrosion is rarely visible at first—until it becomes a serious problem. When structural failures finally appear, their root cause is often found much earlier in the paint process, at a critical and frequently underestimated stage: the ELPO coating. Electrodeposition coating (ELPO) is the first real protective barrier of a car body. If this layer fails, no subsequent process—neither primer coat nor top coat—can truly compensate for it. For this reason, ELPO coating inspection has become a key control point for manufacturers seeking long-term durability, stable quality, and zero surprises in later production stages. At J3D Vision, we […]
