The rollout is backed by ZKONG’s 40,000 square metres of smart manufacturing, with an annual capacity of over 50 million ESLs.
Fully automated SMT, moulding, assembly, and testing lines ensure stable, large-scale production and fast global delivery of all products.
Four-Colour ESLs

The upgraded ESL series is fully compatible with ZKONG’s cloud-native SaaS platform, supporting flexible and seamless template customisation along with centralised management, ensuring consistent pricing and promotion management across stores.
