Product DetailsWhy Kum Yang
One of the Few True Manufacturers
We manufacture ceramic balls ourselves rather than simply distributing them. Our own factory, approx. 4,628㎡ (1,400 pyeong), houses four large kilns and four electric furnaces, handling everything in-house from raw material blending to firing and inspection.
Over Half of Revenue from Exports
We export 50-60% of our ceramic ball sales to more than 20 countries. Our clients include an alkaline water producer in the United States, Nestlé's alkaline water plant in France, and Vietnam's largest water purifier manufacturer.
Proven Quality
We hold ISO 9001, ISO 14001, FDA registration, and RoHS certification, backed by 25 test reports. Our antibacterial balls have been verified to eliminate over 99.9% of E. coli.
Custom Production Down to 1 mm
Producing balls in 1mm increments across a 1-30mm range is a technology unique to Kum Yang. We also offer contract manufacturing, redesigning raw material blends and firing conditions to meet each customer's exact specifications.
Loess Ball Acupressure Park Projects
We have built barefoot acupressure paths at major parks across Korea, including Haneul Park in Seoul's World Cup Park, Naju Railroad Park, and Gyeongnam Arboretum.
