In its early days, Chainsem acquired some used CX200 to meet repair service needs. Over time, the company gradually became involved in turnkey projects. At present, we have 8 different SEM models from CX200 to G5, totaling 15 units, in our facility. In addition to certain models available for test samples, the rest provide customers from around the world a full range of options, enabling us to deliver comprehensive end-to-end services.
