7 Principle of Cooling Channel Planner Heat spot calculation At uniform distance from the mould surface Cooling channel grid Cooling channel search strategy Shortest path Heat seeking Longest path Channel validation Pressure drop Radius validation Modelling of cooling channel in PowerSHAPE Drive curve surface command

8 Cooling Channel Planner Channel strategies Shortest path Heat seeking Longest path Uses Dykstra algorithm Uses distance Minimize length of channel For connection of regions Uses modified Dykstra Heat replaces distance Hot points cost less effort For cooling of hot zones New algorithm Avoid moving closer to exit Uniform cooling of regions

9 CCP: difficulties How to cope with multiple channels? Crossing of multiple channels (e.g. jumping across channels) Keeping channels within a region Etc. Two sections: Yellow heat seeking Green is shortest path Two sections: Green changed to longest path How to control the behaviour? Two channels, no jumping: First one is limiting second

10 CCP: solution + new functionality Work in regions of the mould rather than complete mould Model sections (or parts) of channels Each section can use different channel diameter Each section can use different strategy Connect sections using separate connection grid Multiple solutions for connecting sections Parallel connection Serial connection Old New #1 New #2 New #3

18 D3.2 Determine of the conditions for the Hipermoulding process Design of Experiments The objective of the work package is to establish a base line by measuring the performance of a ‘HIPERMOULDING’ insert in order to compare it with the conventional insert tested in WP 3.1. To achieve a direct comparison the work was carried out with the same equipment as that used for the tests on the conventional inserts: Moulding Machine Mould temperature controllers Thermocouples Flow sensors Pressure sensor The same make and grade of materials were also used.

19 Comparison Between Conventional and LBMM Inserts Both the steel used for the conventional insert and the DM20 material used in the LBMM insert have similar thermal conductivity (~ 30 W/mK) The water flow through both inserts is also similar: This, in conjunction with the information shown in the graphs, suggests that the conformal cooled inserts could facilitate a reduction in the cycle time of a mould; in addition, by broadening the process window, the quality and repeatability of the mouldings may also be improved.
