Injection molding process is commonly used to produce automotive components. Injection molding of polymer components facesx000D
increasing demands for part quality and production rate. Proper thermal management of the injection molding tooling is key tox000D
achieving simultaneous improvements in rate and quality. The devised cooling passages in the tooling manage the heat flow out ofx000D
the plastic. Current fabrication methods place severe limitations on the configuration of the cooling channels used for heatx000D
withdrawal.x000D
The freedom to create internal geometry by the use of Additive Manufacturing (AM) allows for fabrication of molds with complexx000D
internal cooling passages. These cooling channels can be designed to be conformal to the molding cavity. Conformal coolingx000D
channels produced by the AM process provide the ability to more accurately control the temperature of the molding cavityx000D
throughout the process cycle. Such temperature control has the potential to shorten cycle time and to produce parts with lowerx000D
residual stresses.x000D
CO-EX-TEC is keen to move the AM technology forward to open the door for more flexibility in designing tools and molds withx000D
conformal cooling channels that reduce the total cycle time of fabrication and improve the cooling performance of the tool duringx000D
production. This project in partnership with McMaster University, will provide an excellent opportunity for process improvementx000D
resulting in the use of AM technology to produce high performance dies with conformal cooling channels. Upon successfulx000D
completion, the results of this research collaboration will enhance the competitive positioning of CO-EX-TEC in the automotivex000D
supplier market place.
