Design and fabrication of conformal cooling channels in molds

International Journal of Heat and Mass Transfer, 2021
Conformal cooling (CC) channels are a series of cooling channels that are equidistant from the mold cavity surfaces. CC systems show great promise to substitute conventional straight-drilled cooling systems as the former can provide more uniform and efficient cooling effects and thus improve the production quality and efficiency significantly. Although

Automatic design of conformal cooling channels in injection molding tooling

IOP Conference Series: Materials Science and Engineering, 2018
The generation of cooling system plays an important role in injection molding design. A conformal cooling system can effectively improve molding efficiency and product quality. This paper provides a generic approach for building conformal cooling channels. The centrelines of these channels are generated in two steps.

Design and optimization of conformal cooling channels for injection molding: a review

The International Journal of Advanced Manufacturing Technology, 2020
The 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 ...

Design for Additive Manufacturing: Thermoforming Mold Optimization via Conformal Cooling Channel Technology

Procedia Manufacturing, 2020
Abstract The cooling system of thermoplastic mold plays a critical role during the production process because it not only affects part quality but also its cycle time. Traditionally, due to the limitations of conventional drilling methods, the cooling system of the thermoforming mold usually consists of simple paralleled straight channels that ...
