Kindly see our plastic fruit crate mould. So if you want to make such kind of crate mould, how to ensure the quality?

Selecting a good mould design

In order to ensure the cooling effect of crate mould, the design of the cooling waterway must reasonable and effective. Also for the ejecting system, need to use a hydraulic core pulling system to make the crate drop automatically. We add abundant coolings to directly access the crate surface! In addition, adding copper-beryllium can be great to reduce the cycle. But for sure then the crate mould cost will be much higher.

Selecting a suitable mould steel and mould base
