The two end faces of metallized film capacitor cores are coated with zinc, zinc-tin alloy, or lead-tin alloy to achieve excellent electrical conductivity. The 1’Arc-Fro Gold Spraying Machine produced by Beijing United Coating Technology Co., Ltd. employs a fully closed-loop digital control system, ensuring more stable and reliable coating quality with high consistency and repeatability.
Utilizing innovative processes and proprietary technologies, this machine is especially suitable for spraying various types of low-ESR metallized film capacitors. United Coating also provides a range of automated gold spraying solutions, process development, and complete equipment sets. These systems not only maintain stable production cycles but also feature advanced process designs that minimize contamination of the workpiece during coating.
Moreover, the coating hardness and ductility are adjustable to meet the diverse requirements of different capacitor manufacturing processes.
