There are many advantages as a result of the technology Foam Lost, not to mention just a few: – Energy savings, – Automatisation and mechanization of the process, – Castings made from a large variety of materials, such as alloys of ferrous metals, alloys based on aluminum and magnesium...
In this technology, is a stock made from foamed polystyrene (EPS). Foaming of the polystyrene out not only to patrons of confidentiality gurations needed to do but also to achieve the required density. Using appropriate glues are tied together patterns to solid assembly, composed of some patterns with gating...
In the past years, the Lost Foam process is widely used worldwide. According to the data published by Vulcan, in 1997, 460,000 tons of castings produced by this technology worldwide, with Europe having a share in 125 tons. In the USA, 40 stores foundry manufactured more than 115,000 tons...
During sand mold casting, in order to be used repeatedly sand casting pattern are made of relatively tough materials. There are many sand casting pattern materials such like wood, metal, and plastic. A parting and releasing agent is applied on the pattern surface so it can provide a easy removal of...
