This category includes sand molds, chaff, plastic, plaster, and foundries flour (lost wax method). This method of casting molds include temporary and non-processed for use again.
Foundries in sand molds: Sand is one of the most important and simplest ways foundries that have been used throughout the ages. Sand molds allow access to castings (in small payments) are compared to those made in permanent molds and at a reasonable cost. But cost is not the only positive factor for this method, but also the small size of the workshop. Sand also allows for most metals that Zbk by selecting the type of sand used. [6]. You need casting process in sand molds for several days as a period of productivity for high production rate (1-20 pieces / min per template), which is an effective way to produce large pieces. Consolidating sand stick together thanks to clay (in green sand), or by using the Association of materials, or motor oil. Sand can be used for several times, some of the material is added (the renewal of the bonding material).
