Case Study Example However, this system is not suitable to use for twenty parts since it has limitations on casting sizes; usually restricted to cylindrical geometric shapes. #13: The fuel employed in Cupola furnace is gas. Iron foundries are the metal often melted in a cupola furnace. One type of furnace serving a similar purpose as cupola furnace is induction furnace. #14: The two types of furnace used to melt non-ferrous metals include cupola furnace and induction furnace. #15: The molten metal gets to the mold cavity through jolting compaction or squeezing compaction in the mold. #16: The sand that has solidified and cold enough to handle is used in filling those casting, which has hollow sections. #17: It is commendable to wear protective clothing such as safety glasses and heat-resistant clothing due to production of high temperature during these processes. #18: The best way to prevent a cast iron that has broken at the joint is by using the hardened sand to fill the cavity. #19: Impurities and porosity in sand casting, particularly at the top edge next to the riser, is often due to low patterns. On the other hand, material costs are the primary cause of massive shrinkage cavity in this casting. Modification of the pattern and cutting the cost of the equipments are the two remedies for these problems. #20: A hot-chamber casting machine uses high temperature to melt alloys while a cold chamber uses low temperature to melt alloys. Additionally, cold chamber is efficient for low-temperature melting alloys. Chapter 8 Case 1: Machining all holes, cavities and surfaces from solid bars that come in 20 feet long bars, which are sawn off lengths for machining is the best options; options two and three take longer time while options three, four and five are costly. Chapter 8 Case 2: Resin Shell molding is the best method to use in melting small bronze gear because it has rapid production rate and does not use
