BACKGROUND Foundry work is associated with serious occupational hazards. Although several studies have investigated the health risks associated with foundry work, the results of these studies have been inconsistent with the exception of an increased lung cancer risk. The current study evaluated the mortality of Korean foundry workers due to malignant and non-malignant diseases. METHODS This s...

Compared with pure aluminum and wrought alloys, Al foundry alloys are more difficult to be anodized. The high content of alloying elements prevents the uniform growth oxide layer enhances embedding defects in anodic film. microstructure substrate anodizing parameters play a key role final quality layer. Variations chemical composition, casting process, pre‐ post‐anodizing treatments can signifi...

High intensity optical radiation can cause damage to the eye and intense radiation in the range of 770-1400 nm can cause thermal retinal damage. In the workplaces where there are high temperature sources, the workers in front of these hot sources without bright light maybe exposed to the intense IR radiation, thus regular measurement of these radiations seems crucial. Measurement of IR radiatio...

Abstract Specific heat capacity ( C p ), density ρ and thermal conductivity λ ) of phenolic-bonded 3D-printed sand (3DPS) molds have been determined in the temperature range 20–1400 °C using differential scanning calorimeter (DSC), dilatometer, hot wire method. The results used to simulate gradient a mold during casting aluminum commercial simulation software. simulated compared with laboratory...

In the process of industrial evolution, it is a general tendency that companies which specialize in a specific value chain have emerged. These companies should construct a business eco-system based on their own platform to compete successfully with vertically integrated companies and other specialized companies. They continue to sustain their competitive advantage only when they share their abi...

The tensile properties of an alloy can be exploited if detrimental defects and imperfections of the casting are minimized and the microstructural characteristics are optimized through several strategies that involve die design, process management and metal treatments. This paper presents an analysis and comparison of the salient characteristics of the reference dies proposed in the literature, ...

In the global IC industry, business models have evolved into design foundry models and manufacturing foundry service models over the past twenty years. The concept of system-on-a-chip (SoC) refers to integrating all components of a computer or other electronic system in a single integrated circuit (IC). Due to the increasing complexities of SoC devices, it is impossible for one IC design house ...
