The main objective of sand casting

Once all is compacted, the deal is removed from the draw, and the pattern, sprue and riser removed carefully in order to keep the surface features and cavities. The main objective is sand casting mold for part two from the pattern without breaking the mold cavity. After this, the flask is reassembled and pin to the flask to the structural integrity of the mold to maintain. It is ready to be filled with the molten metal can be melted metal.The prepared before the lab now (if available molten metal can be is the part that did).

Student safety is of the highest concern. When the experiment is completed, students prepare beforehand. There should be proper safety attire always needed. Students should express to wear jeans and closed toed shoes. Be sure leather apron, face shield and gloves high temperature for the people responsible for handing the crucible and the pouring of the molten metal. If a student is helping to show, have them pour the molten metal into the mold. Add cup pouring into the sprue for help in placing the liquid into the more efficient model. Be sure to skim off the top layer (slag) of the liquid metal slag with a stick and a pair of pliers.

Steadily pour the molten metal pouring into the cup. This will help in preventing overfilling and clogging. When the mold is filled and the riser fills up, stop pouring. Use safety in handling any hot topic. Leave the mold for a sufficient amount of time to solidify. This will work out well if the class meets the next day or a few days later.During the next class period, remove the pins from the flask and unpack the sand to locate the castpart. Show students the cast and pass the item around. Ask them the instructions in the procedure part of this module.
