1.The plastic chair mould cooling channel quantities as much as possible and the channel diameter as big as possible. the distance between central line of cooling channel and cavity surface is about 12-15mm commonly, the distance of cooling channels is 3-5 times as cooling channel diameter.the cooling channel diameter is 8mm.
2. The distance between each cooling channel and cavity surface should be same.the cooling should be add if the plastic part thickess is not even.
3. The injection gate should be cooling very well.
4.If the cooling channel go through the insert and other connect mould parts, the important thing is sealing, to avoid any water leakage.
5. The cooling channel hole do not design to locate in the area where is the plastic chair Weld Line.
6. The cooling channel diameter according to the everage thickness of plastic chair,commonly,the cooling channel diameter should less than 14mm.
7. Material: PP
8. Function: set
