Design and optimization of conformal cooling channels for injection molding: a review
The International Journal of Advanced Manufacturing Technology, 2020The recent developments in the additive manufacturing make easier and affordable the fabrication of conformal cooling channels (CCCs) compared with the traditional machining techniques. Conformal cooling channels (CCCs) achieve better cooling performances than the conventional (straight-drilled) channels during the injection molding process since they ...

Development of green conformal cooling channels for rapid tooling
The International Journal of Advanced Manufacturing Technology, 2020The production cost is related to productivity greatly in the mass production. To enhance productivity, the rapid tooling (RT) with conformal cooling channel (CCC) is widely used for small-volume production in the current industry. In this study, green CCC for RT was developed. This study proposes four methods to move polyvinyl butyral (PVB) CCC.

Modeling of cooling times for molds with conformal cooling channels and heat sinks
ICALEO 2000: Proceedings of the Laser Applications in the Automotive Industry Conference, 2000In injection molding and die casting, cycle time of the process is dominated by the heat transfer during the solidification and cooling of the part. Molds with conformal cooling and heat sinks with high thermal conductivity can reduce the cycle time considerably.

Visibility-based conformal cooling channel generation for rapid tooling
Computer-Aided Design, 2011In plastic injection moulding process, cooling channel design is an essential factor that affects the quality of the moulded parts and the productivity of the process. Non-uniform cooling or long cooling cycle time would result if a poorly designed cooling channel is adopted. Due to limitations of traditional machining processes, the cooling channel is
