Take the Guesswork out of Windage with Warpage Simulation
Applying Kentucky windage to a mold is not for the faint of heart. However, if a warpage problem cannot be solved through simulation to improve the mold design or process, then windage may be the last resort. If warpage simulation is conducted properly by experienced simulation engineers, it can be leveraged to take the guesswork out of windage, and reduce or even eliminate the tuning loops needed to bring parts into tolerance.
A lesson on shear induced melt variations ends some confusion regarding balancing runner systems for multi-cavity molds.
A few key mold design strategies can go a long way in improving your mold building operations and customer support.
While both hot runner and cold runner systems have their benefits, for design flexibility as well as reduced cycle times and costs, hot runner systems will probably be the better choice.
