Conductive rubber tread materials offer excellent electrical discharging throughout the tread and across the whole contact surface. The steel bracket is Zinc coating so the whole caster is electrical conductive. The caster will then producing a continuous and safe discharging to ensure the safety of electronic devices.

Harms of static electricity in production: Films, bottles and jars are adhered to dust, products do not line up. Or cause sparks leading to fire and explosion. The ink is smudged (crow's feet, beard pulling...). The amount of waste increases due to static electricity causing position deviation when machining.
