After we study the PPSU character, we should know how to choose the steel for the mold, since the mold teperature is about 300 °C-400°C during production, the first important to make the good cooling systems on mold making,if the mold temparature is always high because of poor cooling system, the mold life will be affected, the second the the flowability of PPSU is not good as ABS, PA, we always avoid point gate and make the gate as big as possible.the thrid, produce this kind of mold, we should equiped special screw and nozzle in the injection machine, the high temperature will hurt the normal machine.
