Conformal Coating OB-GC450B

OUBEL OB-GC450B – Automatic Selective Conformal Coating Machine

The OUBEL OB-GC450B is an automatic selective conformal coating machine designed to apply protective coatings to printed circuit boards (PCBs) with precision and consistency. Equipped with a dual-valve dispensing system, it supports both pinpoint coating and fine atomised spraying, helping protect electronic assemblies against moisture, dust and corrosion while minimising unnecessary coating application.

Featuring servo-driven X, Y and Z-axis movement, a stainless-steel chain conveyor and adjustable coating controls, the OB-GC450B delivers reliable performance for demanding PCB manufacturing environments. Its adjustable conveyor speed, user-friendly operation and efficient exhaust system help improve coating accuracy, production efficiency and workplace cleanliness.
