SLM tooling for die casting with conformal cooling channels [PDF]

The International Journal of Advanced Manufacturing Technology, 2013
The paper reports an experimental study of die-casting dies with conformal cooling fabricated by direct-metal additive techniques. The main objective is to compare the benefits and limitations of the application to what has been widely discussed in literature in the context of plastics injection molding. Selective laser melting was used to fabricate an

Case Study to Illustrate the Potential of Conformal Cooling Channels for Hot Stamping Dies Manufactured Using Hybrid Process of Laser Metal Deposition (LMD) and Milling

Metals, 2018
Hot stamping dies include cooling channels to treat the formed sheet. The optimum cooling channels of dies and molds should adapt to the shape and surface of the dies, so that a homogeneous temperature distribution and cooling are guaranteed ...

Design, Characterisation and Numerical Investigations of Additively Manufactured H10 Hybrid-Forging Dies with Conformal Cooling Channels

Metals, 2022
Internal die cooling during forging can reduce thermal loads, counteracting surface softening, plastic deformation and abrasive die wear. Additive manufacturing has great potential for producing complex geometries of the internal cooling channels.

The design and additive manufacturing of an eco-friendly mold utilized for high productivity based on conformal cooling optimization

Materials & Design, 2022
This study proposes an eco-friendly (ECO) mold that is fabricated using the laser powder bed fusion (LPBF) method, which utilizes a three-dimensional (3D) cooling channel. Unlike previous studies, we designed surface-type conformal cooling channels (CCC)

A Thermomechanical Analysis of Conformal Cooling Channels in 3D Printed Plastic Injection Molds

Applied Sciences, 2018
Plastic injection molding is a versatile process, and a major part of the present plastic manufacturing industry. The traditional die design is limited to straight (drilled) cooling channels, which don’t impart optimal thermal (or thermomechanical)

Automated Design of Honeycomb Conformal Cooling Channels for Improving Injection Molding Quality

Production Engineering Archives, 2023
The study of conformal cooling channel usually has adopted two assumptions in model design: the use of (1) a hot runner system and (2) a one-mold-one-cavity design. These assumptions substantially simplify the research.
