Innovative Design for Cost Reduction
ST YOUNGWON is collaborating with customers from the initial stage of facility design to reduce design lead time and minimize problems that may arise when producing separators.
Through 3D simulation, functional elements of the facility can be predicted and thus the performance and stability of the separator facility can be greatly improved.
Given the high CAPEX in separator business, ST YOUNGWON offers various design options – from basic to custom – to help customers optimize costs while meeting their needs.
