We have made many tools for this customer. Our designers work very effective, for DFM, it can be finished within 1~2 days, 2D layout within 2~4 days, and 3D within 3~5 days depending on mold complexity. When time is very urgent, we normally make 3D drawing directly after DFM, but of course, it must be based on customers’ approval.
