DFM and other technical analyses in the early stage of the project development, from the product structure to the feasibility of mold manufacturing, from the realizability of drawing tolerance and the determination of measurement methods, from the discus sion of plastic particles to injection molding process, and the subsequent mass produc tion evaluation of LDs, surface treatment, assembly and other related processes, all reflect our scientific and rigorous attitude towards technology. As a result, we have made great contributions to our customers' QCDS (quality, cost, delivery time and service )!
