Amid the wave of electrification and intelligence, automotive cabins are rapidly transitioning from function-driven to experience-driven designs. Interior trim components have evolved from supporting roles to key elements of vehicle design language. Metallic finishes, semi-transparent luminous effects, and multi-functional integration are pushing manufacturing technologies to new heights. Meanwhile, facing challenges in yield management and process consistency during mass production, an increasing number of component manufacturers are reevaluating the adaptability and scalability of their coating equipment.
The ability to stably deposit multi-functional film stacks is becoming a new benchmark in equipment selection.
1. Evolving Interior Trim Design is Reshaping Coating Processes
From headlight reflectors to illuminated logos and ambient light guides, the proportion of automotive interior components requiring coating processes continues to rise. Manufacturers no longer merely demand “coating presence” but rather precise control over brightness, reflectivity, transmittance, high repeatability, substrate compatibility, and reliability validation.
This shift is phasing out traditional single-layer metal coating + spraying methods, replacing them with multi-layer film stacks. In terms of deposition processes, controlling interlayer adhesion matching and deposition rate stability has become the most critical challenge in mass production.
Common pain points from customer feedback include “non-uniform coating thickness,” “significant thickness variation between center and edges,” and “inconsistent batch uniformity.” These issues reflect real gaps in equipment design, such as chamber structure, target arrangement, temperature control, and process switching efficiency.
2. From “Capable” to “Consistent”: Equipment Performance Becomes a Priority
As automated production lines become mainstream, the industry demands more from coating systems—not just “deposition capability” but also “batch controllability,” ensuring film uniformity, process repeatability, and equipment stability across every production run.
Under this trend, structural design, process integration, and changeover efficiency are now decisive factors. Customers increasingly prefer solutions that “complete metal + protective layers in a single run” and “eliminate post-coating cleaning” to minimize contamination and improve yield.
A truly future-proof system is not just a deposition tool but a stable, efficient, and flexible hybrid solution.
