Primljeno (Received): 2011-11-07 Prihvaćeno (Accepted): 2012-03-15 Original scientific paper Abstract: Pressure die casting is the method used for forcing molten metal into mould cavities under high pressure and at high speed (10 100 m.s). Pressure die casting is a highly productive method of casting parts with low dimensions tolerance and high surface quality. From the point of view of product...

We present an innovative approach to casting process planning based on case-based reasoning. Process planning involves deciding the methods, materials and machines for various steps in manufacturing. It is an important activity that affects product cost and quality, and requires experience. Such experience can be stored using a knowledge management system, then retrieved and modified for a new ...

The purpose of the work is to evaluate the EMF levels in the surroundings of particular induction heating installations used for melting metals and some methods for mitigating them. The data from measurements in a metal foundry will be presented and discussed with reference to the limits for occupational environment. In some cases the measured levels overcome the ICNIRP limits. For these cases ...

[Purpose] This cross-sectional study aimed to compare foundry workers of the metallurgical industry with high and low exposure time and with a control group. [Subject and Methods] The workers were evaluated for pulmonary function and peak expiratory flow (PEF), respiratory symptoms, smoking habits, and physical activity level. Descriptive statistical analysis and ANOVA one-way test were used. [...

A scheduling problem for an engineer-to-order foundry that manufactures propeller blades for ships is outlined. The main objective for the foundry is to find an efficient production plan that minimizes the total number of days orders are late. This has to be done subject to a set of relatively common constraints related to the scheduling of the present jobs and resources. The constraints on the...

A 20-year follow-up of a population sample of men aged 25-34 has been completed in Staveley, Derbyshire. The sample was based on a private census, with brief industrial histories, that enabled four groups to be established--"non-dusty," "pure coal-mining," "pure foundry," and "other and mixed." The similarity of the mortality rates of non-dusty, coal-mining, and foundry groups is satisfactory, ...

background: foundry workers are occupationally exposed to hazardous substances such as silica dusts and toxic gases. the aim of this study was to examine the effects of simultaneous exposure to complex mixtures of silica dust, formaldehyde, and triethylamine on lung function parameters. study design: a cross-sectional study. methods: this study was conducted on 55 male workers of core making un...
