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.

Design of conformal cooling channels for an automotive part
International Journal of Automotive Technology, 2009The cooling system plays a crucial role in determining the productivity and quality of an injection molding process. With the current growth of Solid Freeform Fabrication (SFF) techniques, mold designers have been striving for not only improvement in cooling system performance but also for a method to do so automatically.

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

Manufacturing optimization of laminated tooling with conformal cooling channels
Rapid Prototyping Journal, 2011PurposeThis paper proposes sheet thickness determination in manufacturing of laminated dies as an optimization problem. The aim of this optimization procedure is finding the best set of thicknesses which minimizes the volume deviation between actual computer‐aided design (CAD) model and assembled slices.Design/methodology/approachThis works uses a ...

Variable Radius Conformal Cooling Channel for Rapid Tool
Materials Science Forum, 2006The cooling system of a plastic injection mould is important as it affects the quality and productivity of the polymeric components or assemblies. Contemporary cooling channel design is confined to simple configurations of straight-drilled coolant passageway around the mould insert.

Analysis and Manufacturing of Conformal Cooling Channels in Injection Mold
Applied Mechanics and Materials, 2014In view of the cooling difficulty in complex injection mold, the difference between conventional cooling channels and Conformal Cooling Channels (CCC) is researched. CCC is superior to conventional cooling channels on cooling effect according to the simulation analysis of plastic flow based on Autodesk Moldflow Insight software.

Design of Conformal Cooling/Heating Channels for Layered Tooling
2008 International Conference on Smart Manufacturing Application, 2008One of the advantages of Rapid tooling (RT) methods is flexibility in building conformal cooling/heating channels within a mold for enhanced thermal control, but tool size is currently limited. But Profiled Edge Laminae (PEL) method, which is a thick-layer laminated RT method intended for large-scale tooling applications, could allow more challengeable
