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.

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.

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

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 ...
