The competition in automotive painting is extending from "comparing coatings" to "comparing production lines".
How should a paint production line be planned and constructed to meet increasingly stringent coating quality requirements while controlling manufacturing costs such as electricity consumption, labor, and factory buildings?
At the "2026 Automotive, Special Purpose Vehicle, and Component Coating Conference" hosted by Paint Procurement Network, Rucca "moved" the entire production line to the venue, and the answer given was: * * Design dispersion and grinding as a process chain, and then deliver the entire line to solve quality and cost in one go. **
##First, stabilize the quality: ensure proper dispersion and grinding
Falling into the workshop, the pressure on the paint production line manifests as a series of old problems: powder bag opening and feeding, dust dispersion, and unorganized VOC emissions; Pre dispersion relies on manual mixing tanks, resulting in uneven wetting, and the sand mill can only grind repeatedly; Change the color and clean the entire line for half a day; The fineness fluctuates between batches, and the stability of the color paste often depends on the supervision of the master craftsman; There are many manual labor, large land occupation, and high electricity costs.
Quality needs to be stable and costs need to be reduced, and the answer obviously does not lie in a single machine.
One of the quality roots of the paint production line lies in the fineness and batch consistency of the color paste.
The traditional method involves dividing the powder feeding, pre dispersion, and grinding into several sections and relying on manual connection. Insufficient wetting results in agglomerates entering the grinding chamber, causing the fineness to fluctuate naturally. Rucca's approach is to achieve dispersion directly online: * *Inline dispersing system-low viscosity IDS * * dust-free feeding, closed powder suction, online high shear, the powder is evenly dispersed before entering the sand mill, reducing agglomeration and "fish eyes" from the source; **DF-High efficiency disk horizontal bead mill * * is designed for stable mass production, with continuous operation for a long time without drifting in quality. When it is necessary to increase production capacity, multiple machines can be connected in series.
More importantly, the coordination between the two processes is crucial.
Rucca does not allow any device to be "ground to the end": dispersing aggregates in the front and focusing on precision grinding in the back, energy is not wasted on repeated depolymerization. When it comes to the production line, it means that after grinding several times, energy consumption has decreased, batch fineness has stabilized, and the downtime for color change and production has been shortened - fineness stability and batch consistency are the basis for coating gloss and color consistency in the color paste.
##Controlling costs again: a line from design to production
What is more impressive than a single machine is the overall line capability.
Many suppliers in the industry come to an end after selling out their equipment, and how to string the production line and match the process often requires customers to spend more energy to solve. Rucca does another business: from raw material transportation and measurement, to dispersion, grinding, painting, filtration, filling, to VOC treatment and safety production, the entire line is planned, built, and delivered together. **
The value of this delivery method for automotive painting, which requires both quantity and frequent color changes, is very practical: materials are first sampled and verified in the laboratory, the process is confirmed, and then scaled up to mass production, with parameters that can be translated; Fully enclosed and automated pipelines, both labor-saving and more stable; The series layout of coarse and fine grinding maximizes production capacity.
The so-called "save investment, save labor, save site" relies on this integrated design - reducing electricity consumption, saving manpower
