1, DingTong will continue focus on new mold/die development,
tooling spare parts, molding and stamping production. To invest
more people, more tooling equipment, stamping press, molding
press etc.
2, In the year of 2009, we set up a 2nd plant in Henan province,
which mainly develop in IC, semiconductor, overmolding, insert
molding and etc. areas. The total investment is reached $6
million. The plant area is around 10000 square meters. We will
continuously expand our plant, enhance production ability and
improve product quality to satisfy our domestic and global
customers requirements.
