We have reached cooperation with Yixing's molding factory, and the shell materials have been transported to Yixing. It may take 1 month to make a mold for shell forming. We try to use the mold of our previous supplier, but we need to confirm whether the mold matches the press of Yixing. If so, we will save the time of forming the shell.I will make a timetable for approval process when confirm the time of shell finished.we have materials for make 50 accumulators.
