Complex and Multi-cored Resin Sand Casting Process- 3D Animation

Sand casting offers versatility when creating parts with complex geometries and intricate features. The process has been in use for several centuries. This video is created by 3D animation to illustrate the critical steps of the sand casting process vividly. The pattern for the mold and sand cores will be created based on the product's specifications. Sand is used in the mold creation process. Sand has refractory properties, as it can withstand the heat while maintaining its shape. The sand will also typically have other materials added to it, such as bonding agents to assist with holding the mold together so it can undergo the pouring of the molten metal. The entire sand mold process is done within a box called a flask. There will typically be two parts of the box, a top part which is called a cope and a bottom part which is called a drag. These two boxes will be clamped together to make the 3 dimensional part. The pattern will also have gates and risers added when placed into the sand mold. Gates and risers are pathways leading to the main pattern and out of the sand mold. The molten metal will be poured into these pathways as it will flow into the center of the pattern mold. When the metal contracts, the excess metal in the gates and risers can settle back into the pattern to fill every crevice. The bottom mold box (drag) will be partially filled with sand as then the pattern and gating system will be added. A core, which is a type of shaped sand, will sometimes be placed inside to help shape some of the interior casting surfaces when the pattern itself doesn't contain these features. To help support the core in place, core prints and metal pieces called chaplets are added. Then the top of the mold box, the cope, is clamped in place on the drag. Then the drag box is filled the rest of the way with sand until the pattern, gating system and core are covered. The box is compacted to ensure that there are no gaps. Excess sand becomes removed as now the cope is removed from the drag so that the pattern and core can be carefully extracted. With the pattern and cores removed, the created mold shape will be prepared for the molten metal. A type of lubrication will be added so that once the molten metal cools, the casting will be easier to take out as the lubricant can also help provide a better surface finish. Next, the cope and the drag boxes are secured together. Weights will be used to keep the cope in place so that it doesn't rise when the metal is poured inside. The metal now can enter the mold through the gates and risers. The metal is now allowed to cool. Once the metal cools and solidifies, the sand can be shaken from the drag and cope boxes. The sand is broken apart and is recaptured as it can often be reused. Once the metal part is removed from the flask, it will go through a final finishing process. This process involves cutting away all the gates, risers and runners connected to the metal part. Then the part will be sandblasted and ground to achieve the desired smoothness and surface finish. To recap, the process to make a sand casting involves six critical steps: • Pattern Design and Creation • Sand Mold and Sand Core Creation • Gates and Riser Creation • Melting and Pouring • Sand Shakeout • Finishing By understanding the process that is involved with sand casting, customers will be able to determine if this technique will be suitable for the component and product creations.
