In a survey of health and environmental conditions in the Butterley Foundries (Keatinge and Potter, 1945) one of the principal health risks to which the workers were exposed was found to be pneumoconiosis, and it was estimated that the potential dust risk of fettlers was many times greater than that to which other workers in the foundries were exposed. Sixty foundry men, divided into broad occu...

A device composed of two junctions, but operating as a photodiode is designed and implemented in a pre-production 1 μm complementary-metal-oxide-semiconductor silicon technology foundry service. No process modification is performed. Tests are performed at a wavelength of 783 nm. Rise and fall times in the nanosecond range are reported along with sensitivity and bandwidth measurements. The suita...

Microelectronics is the dominant industrial technology of today. Its rate of innovation, spelled out by Moore’s Law, is exceptional by any commercial metric, especially, as it has been on this trajectory for almost 40 years. It is not surprising, that other industrial sectors are taking advantage of the innovation engine of the semiconductors for its own product innovation: Cars are safer and m...

This cross-sectional study was conducted in a foundry factory to assess the prevalence of respiratory symptoms and occupational asthma in foundry workers. Physical examination, spirometric evaluation, chest radiograph, and a questionnaire related to respiratory symptoms were performed. Monitoring of peak expiratory flow rates, spirometric reversibility test, and high-resolution computed tomogra...

BACKGROUND This study investigated the prevalence of ocular and respiratory symptoms and lung function in foundry workers exposed to isocyanic acid (ICA) and methyl isocyanate (MIC). METHODS Foundry workers (n = 64) using the Hot Box binder technique and referents (n = 134) completed two questionnaires and a spirometry before and after a day shift. Findings were analyzed relating to exposure ...

Casting has various processes like Pre casting Processes, pattern making, core making, molding and mold assembly making, Casting Processes, furnace charging, melting, holding and pouring, and Post casting Processes, shakeout, inspection and dispatch etc. In India there are many foundry have followed conventional and manual operations. Today’s competitive environment has, lower manufacturing cos...

To avoid increasing costs of landfill disposal, it has become increasingly important for U.S. foundries to identify beneficial reuses for the 8 to 12 million tons of waste foundry sand (WFS) generated annually. A major drawback to the reuse of some WFSs as a soil amendment is their high soil strength, under dry conditions, where root growth may be limited. Fifteen WFSs were analyzed for strengt...

BACKGROUND Awareness about lead poisoning in South Korea has increased; however, occupational exposures occurring in small-scale businesses have not been thoroughly investigated. We report two cases of high lead exposure in a leaded bronze ingot foundry. CASE PRESENTATION Two employees, a 54-year-old primary operator and a 46-year-old assistant, at a small-scale metalworking company who had b...
