Complete information about Sand Casting and its process Sand Castings Have you seen gas lines in your home , from the basement to the rest of the house ? The surfaces are very smooth , right? That's because the pipes were thrown by the method of sand casting . Casting Process This method of cast aluminum, brass, iron or other metal tubing will irregular surfaces are slightly rough to the touch . When aesthetics is not an issue , casting sand is the best choice . Briefly, the molten liquid metal is poured into molds made by forming cavities , that are replicas of the desired object , in a mixture of sand . A continuation of cool metal into the mold. Once the sand becomes compact and the molten metal is hardened , then remove the cast to break the sand mold. You can smooth the rough texture on the surface of the plaster with a grinding or polishing and preening hammer. When the mold is broken to get the deal, you have to make a new mold every time you want to convert an object. Cast Iron Items The type of sand and the molding process generally limits the accuracy of objects cast. So you have to improve the finish sanding and polishing. You can launch a large iron bell or a small part of the automotive by sand casting method . Iron foundries use a large amount of sand to lay foundations for tables, bars and locks. Iron tables are often installed in shooting ranges where strength , weight and durability of the table are of paramount importance. Disadvantages of sand casting Although this method of casting is still frequently used for metal pipes and other items , there are drawbacks to their use : 路 Machining and finishing costs . As the surface texture of the cast is uneven, have to incur great expense to improve the article through grinding and polishing machine . 路 Using the material. You have to make a new mold every time you want to launch a new object. This is costly in terms of material used , as many sand molds have to be made .
路 Unusable casts. Due to the nature of the casting process , there is a risk of melting of objects that can not be used . This would lead to wastage which increases production costs . 路 Parts high. Horizontal molding lines in factories require a large number of spare parts for its mobile sections. This is compounded by low productivity , which allows only 90-120 sand molds to be made per hour for each molding unit . However, the horizontal lines are most commonly used in comparison with vertical molding lines , which are much more efficient , producing up to 550 sand molds per hour with an efficiency rate of 98% . Sand casting is a simple and popular technique to duplicate objects from metals. You can make lasting and complex shapes using sand molds . You can smooth the texture of the objects cast by grinding and polishing to achieve greater accuracy in dimensions. This method of casting probably prevail in the future .
