Fan mould

we have made many of fan mould sets, the most important point  is the fan blade mould, it need the very even injection points to keep the plastic filling the blade moulds’  at the same pressure and same distances. at the same time, we have to know that the different  moulding area’s temperature will caused the filling not even. this will cause the fan blade parts’gravity point not in the center, so when the blade turning, there will have ugly noise. We know how to make injection even and cooling effects on the moulding areas  and makre sure they are at same value.
