Several questions about chair and table mould.
- Can you tell your chair mould running cycle time?
If the cooling water temperature is from 8 to 12 centigrade degree, if the chair weight from 1700g to 2400g, the cycle time should be 35s to 50s. If the machine plastic melt and injection is with accumulators. Please check how they make the cooling channel? If the cooling channel is extra in and out? If the cooling channel is one according with the chair shape?
- How you guarantee your chair mould run shorts?
Many people will say that they will have one millions guaranteed. But God now how can they guarantee. The guarantee for a mould run 1 million shorts without any flashes? Because if you accept to cut the flash by your workers heavy labor, I think you can use this mould for 10 millions shorts. So you need to check the steel hardness, and in the mould if there is any parting area were welded. Normally the steel hardness should be HRC33.
