Ultra hard silver plating for EV car charging terminals and connectors (plating technology)

A unique mass production technology born at the same time as the beginning of EV cars! Pursuing hardness and achieving cost reduction! With well-equipped mass production facilities, both wear resistance and conductivity are realized!

This is a hard silver plating that achieves both low cost through wear resistance and reduced film thickness. Even with a thin film thickness, it ensures sufficient hardness. Even if the film thickness is increased, the surface of the plated film maintains smoothness suitable for terminals and connectors (proven: up to 100μ). The thickness and hardness of the silver plating film are managed with measuring instruments, characterized by small variations in measurement values. If silver plating is needed for terminals and connectors... "We need to make the film thick to ensure hardness, which increases the plating cost." "If we make the film thick, the plating film won't be smooth." These challenges can be overcome. We can solve the concern of wanting to reduce the thickness of hard silver plating while still needing hardness. 【Features】 ■ Well-equipped mass production facilities that maintain high quality ■ The surface of the plating film maintains the necessary smoothness for terminals even with increased thickness ■ No cracking or peeling of the plating film ■ Small variations in thickness and hardness of the plating film even in mass production ■ Also used for movable/fixed terminals and seal rings/gaskets (up to φ400) ■ Partial plating is possible, plating only where needed.
