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 ...

Materials Today: Proceedings, 2020
Abstract Cycle time is a significant parameter in injection molding process as it affects the rate of production and governs the quality of part produced. The cycle time can be reduced by minimizing the cooling time. Cooling time contributes to the majority of the cycle time and it can be effectively reduced by proper heat dissipation.

International Journal of Precision Engineering and Manufacturing, 2022
The design principle of an additively manufactured (AMed) lattice structural conformal cooling channel for hot stamping is investigated. AM with selective laser melting is adopted to fabricate a lab-scale rapid cooling die filled with conformal lattice structures, which provide structural stiffness, act as thermal fins, and expedite the occurrence of ...

Hybrid Wire-Arc Additive Manufacturing of Conformal Cooling Channels: A Feasibility Study
International Journal of Precision Engineering and Manufacturing-Green Technology, 2022This paper investigates the feasibility of hybridizing wire-arc additive manufacturing with metal forming to create conformal cooling channels in moulds for hot material processing. An axisymmetric mould is used as a prototype test case and plastic deformation by flaring of the additively deposited inner tubular element is utilized to create the ...

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.

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
