Sino Mould is a good marker for ventilation system molds,like plastic fan blade molds,plastic grating mold,air handing molds,For those molds need very high precise for the each dimensions, they are high precise in assembling dimension, each holes,each pins of the ventilation system molds, so, some machining need with High speed CNC,SODICK DEM for ventilation system molds, it is keep the product’s precise.

* For some fan blade molds, one kinds of

* For some fan blade molds, one kinds of ventilation system molds, we will keep the blade molds’s plastic filling are same pressure and distances, to keep the filling even or not,because if not even the blade’ gravity point will not in the center, so there will have undesired sound when fan blade running, and not long life for fan blade parts. And without flashs in the blades.

*For the panel of ventilation system molds, it is need high polish,and the surface can not have shrinkage mark.
