Good afternoon! How to determine the minimum dimensions of the form that can be installed on the injection molding machine?
The distance between the columns is 450x450, I put an injection mold with dimensions of 250x250, is this acceptable? Is there a rule for this? Regulations by ratio ?
Hi,
Generally speaking the mold / machine combination is determined by the tonnage needed to make your part. The smaller mold is just not running as efficiently from a machine hour cost basis in that size of a machine. The machine should have a minimum "Die Height" or distance from the moveable to the stationary platens when it is fully closed. that would determine whether you can run that mold in the machine.
typical rule of thumb, 2/3 coverage of the platen.
hello, usualy the minimum mould dimensions are mentioned in machine drawings. If not, is there a rule, take a minimal distance between ejector holes on moving side and this is minimal toolsize - for full tonage.
minimal distance between ejector holes on moving side...
But Pilot, there is only one hole at ejector side? Which one I should take :D
To Jendalf: tool must be bigger than this hole :-)
