One of the longest, most technically complex and environmentally demanding processes in modern automobile manufacturing — determining both the aesthetic quality (color, gloss) and the first line of corrosion defense for every vehicle body.
A complete automotive coating system consists of core processes — pretreatment, electrophoresis, sealing/adhesive, primer, basecoat, clearcoat and inspection — organized into six major systems: body transport, pretreatment & electrophoresis, grinding & sealing, spraying, drying oven, and exhaust-gas environmental treatment.
SYZOY designs and integrates turnkey coating lines and brownfield upgrades for passenger cars and commercial vehicles, engineered for production targets from 30 to 120 JPH. Every booth, oven and conveyor is validated with CFD and structural analysis before fabrication.
The pretreatment system delivers a clean metal surface with appropriate roughness for maximum coating adhesion.
The electrophoresis system is the key process ensuring 10+ years of corrosion resistance for the body.
The drying oven cures each coating layer through controlled thermal stages:
The conveyor accurately and stably transfers the white body between process stations. Coating conveyors have evolved from ground chains to pendulum, skid and multifunctional shuttles.
The spraying system is the most core and precise part of the coating workshop — directly determining final color, gloss, brightness and paint utilization. Modern lines are dominated by robotic automatic spraying.
RTO (Regenerative Thermal Oxidizer) is the core environmental equipment for treating painting VOCs (benzene, toluene, xylene) from booths and ovens.
