MICON MOULD is a Chinese crate mould manufacturer, we has developed more than 100 sets various crate moulds such like, beer case mould, spare parts box mould, storage box mould…..
A, do you need a high production performance crate moulds?
B, do you need the automatic ejection function for the cola bottle crate mould?
C, do you want to use the recycled plastic material to molding the one-time using crate?
If you need all these question to be solved and clarified, please come to MICON Mould for crate mould and plastic crate molding solutions.
1, How to make a long life running crate mould?
a, Choose the correct steel for mould base and mould main steel. to use a pre-hardened steel with HRC bigger then 33 for mould base and choose the correct steel or material for the durable mould components.make the correct harden treatment to each steel piece and make the steel hardness controlled, you can not make it too hard.And then before shipping, can make nitriding for the sliders. Then this mold can have a mold life from 1Million shots or running for 3years continuously.
b, To make the best optimal cooling effect, for durable plastic crate mould
We should connect the water channel input and output as many circuit as possible. That is mean to make the crate mold with more separate cooling connections.
For the crate mold core, design the cooling channel up to surface 15mm below the molding surface. And the diameter of the crate mold cooling channel should be more than 12mm diameter, so that the water can run flow smoothly in the channel while take away the heat from the core.
For the crate mold sliders, also, make the cooling channel more close to the crate molding area.
For the crate mold cavity cooling, also should design the best cooling for cool down the hot runner tip area.
By doing the above mentioned design of cooling channel, you can reach a standard crate molding cycle time around 45 to 50 seconds.
c, Plastic crate mould design is very important, it is better to use a mechanical system onto the crate mould ejection, in this way, you can make the ejection action when the mould opening. Of course, maybe your machine can work with the 2 hydraulic acting in the same time, then you can do the ejection when the mould opening.
