It can, if the steel is real, the DFM is done before cutting, and someone checks the T1 parts against your drawing instead of against the mold.<\/p><p>That is the whole job of mould tooling here. We design the tool, cut and fit it in our Huangyan shop, sample it on our own presses, and ship the mold or run production for you. Every China injection mold we build comes with a steel spec, a T1 dimensional report and weekly progress photos.<\/p><p>Need parts rather than a tool?
