8 Major Steps involed in the Investment Casting Process

1. 8 Major Steps involed in the Investment Casting Process ---------------------------------------------------------------------- Investment casting is a metal-forming process where molten metal is typically poured into an investment, or mold, that hardens and shapes the metal around it. Investment casting does not usually use compression to shape the metal; instead, it relies on gravity pressure. Below are the steps used in the investment casting process; Step 1: Creating the Pattern The first step in the investment castings process is creating the die/pattern. This process includes making a pattern or model of the object and then employing specialized materials to create a rubber mold. T Step 2: Mounting the Wax Patterns After making, patterns must be attached to a flexible material such as rubber or silicone. This will allow the metal to fill every nook and cranny. Step 3: Tree Assembly Once the mold is finished, investment casting can begin. The semispherical tree will be dipped in wax to provide a surface that allows molten metal to flow into it. Step 4: Shell Molding Shell molding is the first step in creating a metal shell within the mold. Molten metal is slowly added to the cavity within the tree and allowed to cool.

2. Step 5: Wax Removal Before pouring molten metal into casting, wax should be removed. This process involves heating the wax to allow its removal. It's then placed upside down to pour it out. Step 6: Mold Casting Once the wax is removed, open spaces will remain inside the shells. So, molten metal is poured into the casting. The metal will cool in its mold and form a casting of the original pattern. Step 7: Remove the Shelled Casting The shell can be removed after mold casting. A tool like a hammer will be used to remove any shell casting to leave only the original tree. You will now get the finished workpieces on the tree. They are then melted and refined. Step 8: Finishing Operations Every workpiece is scrutinized for imperfections; when found, they're discarded. The material can still be used after that. All that remains is to finish the workpiece by grinding and polishing to ensure the object meets all specifications. Conclusion The above are the steps used in the Investment casting process. Investment casting is a very complex process that follows certain steps from start to finish. This will allow you to understand more about this process and its benefits during your job search. This process is helpful in creating many of the products we see today. So, it is ideal that you know the exact steps to make these precious products.
