Spiral and conformal cooling in plastic injection molding
CAD Computer Aided Design, 2015 Designing cooling channels for the thermoplastic injection process is a very important step in mold design. A conformal cooling channel can significantly improve the efficiency and the quality of production in plastic injection molding. This paper introduces an approach to generate spiral channels for conformal cooling. The cooling channels designed by

Automatic design of conformal cooling circuits for rapid tooling
CAD Computer Aided Design, 2011 This paper presents an automatic method for designing conformal cooling circuits, which is an essential component that directly affects the quality and timing for products fabricated by rapid tooling. To reduce the time of cooling and to control the uniformity of temperature and volumetric shrinkage, industry expects to have cooling channels that are ...

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 ...

Conformal bubbler cooling for molds by metal deposition process
CAD Computer Aided Design, 2015Molds with conformal bubbler cooling channels have been developed in order to reduce the cycle time of the plastic injection process, which in turn has increased the production rate. In addition, part warpage can be greatly reduced in the injection process because the temperature distribution is uniform over the mold surfaces.

An investigation on conformal cooling in plastic injection moulding
, 2011 One of the most important features of mould cooling in injection moulding is the provision of suitable and adequate cooling arrangements. For many years, mould designers and researcher have been trying to improve the performance of cooling system, despite the fact that cooling system complexity is physically limited by fabrication capability of ...

Conformational study of jet-cooled L-phenylglycine
The Journal of Chemical Physics, 2008We investigated the conformational structures of L-phenylglycine in the gas phase by photoionization and double resonance spectroscopy techniques as well as high-level ab initio calculations. The UV-UV and IR-UV double resonance spectroscopy suggested that there exists only one conformer that has a free OH band for the carboxyl group.

Removable, conforming device for cooling the cortical surface
Brain Research Bulletin, 1979A technique for cooling the cerebral cortex is described. It makes use of a neoprene bladder through which cold fluids is circulated. The flexible bladder is contained within a cylinder permanently attached to the skull. The bladder itself can be quickly installed and removed and conforms to the cortical surface with minimal pressure.
