Case story about the definition & implementation of an industrial enameling plant for electrical water heaters

An OEM of electrical water heaters aimed to reduce the cost price of their products, while improving its lifetime.

Wished to switch the watertank substrate from copper to mild steel with porcelain enamel coating.

During the definition stage of this project, DTC reviewed whether the product design was suitable for enamel coating.

Once confirmed, we also recommended appropriate enameling processes, provided an indicative CAPEX budget and estimated enameling cost per water heater model.

Upon approval of the investment budget, DTC assisted with the vendor identification & selection and procurement of the necessary enameling machinery.

During starting-up & initial production phase, DTC supplied various process & quality control equipment, provided on-site staff education and assisted with troubleshooting minor quality issues
