Characterization of the Strength of a Natural Sand and Artificial Sand Core Manufactured with Inorganic Binder
물유리계 바인더로 제조한 천연주물사와 인공주물사 중자의 강도 특성
Min A Bae, Pan Seong Kim, Kyeong Ho Kim, Man Sig Lee, Jae Ho Baek
배민아, 김판성, 김경호, 이만식, 백재호
Korean J. Met. Mater. 2021;59(4):273-280.   Published online 2021 Mar 24
DOI: https://doi.org/10.3365/KJMM.2021.59.4.273

Abstract
Natural sand and organic binders are commonly used in casting processes, but these ingredients produce environmental problems with dust and harmful TVOC(Total Volatile Organic Carbon) gases. Research on the introduction of artificial sand and inorganic binders to solve these environmental problems is being actively conducted mainly in the casting industry...... More

      
The Effect of the Surface Energy of Water Glass on the Fluidity of Sand
Min A Bae, Man Sig Lee, Jae Ho Baek
Korean J. Met. Mater. 2020;58(5):319-325.   Published online 2020 Apr 20
DOI: https://doi.org/10.3365/KJMM.2020.58.5.319

Abstract
In recent years, the metal casting industry has sought to meet ever more stringent environmental standards. Inorganic binders based on silicate chemistry have many advantages with respect to environmental issues, but often suffer from reduced strength, burn-on and poor water-resistance. In particular, when sand is mixed with a water glass..... More

Effects of Jetting Parameters and Sodium Silicate-Based Binder on Droplet Formation
액적 형성에 미치는 물유리계 바인더의 조성과 토출조건의 영향
Seongeun Pyeon, Man Sig Lee, Dae-Won Park, Jae Ho Baek
편성은, 이만식, 박대원, 백재호
Korean J. Met. Mater. 2020;58(4):278-285.   Published online 2020 Mar 10
DOI: https://doi.org/10.3365/KJMM.2020.58.4.278

Abstract
Binder jetting additive manufacturing is one of the 3D printing technologies currently used to manufacture 3D geometries. In this process, a liquid binder agent is ejected to a desired position of a substrate. The binder’s properties and the jetting condition used for form droplets can affect the formability of the.....
