The lost wax method simply consists of replicating the object to be cast in wax, then immersing it in a pool of sand/powder and leaving it to dry, so that the wax replica is covered with a sand coating. The wax replica is then covered with a sand coating and the procedure is repeated until the coating is sufficient to support the casting process, after which the wax is melted from the mold and withdrawn from the mold. The mold then needs to be heated several times to increase the hardness before it can be cast. This method has good accuracy, but is quite costly due to the high price of the sand/powder and the complexity of the production process, which requires several heats. expensive.

To take out the model before pouring the metal, Sand Casting should be made into two or more parts; during the mold making process, holes and vent holes for pouring metal into the mold must be left to synthesize the casting system. Sand Casting keeps the metal liquid for an appropriate time until th

The process and precautions of investment castingInvestment casting, also known as lost wax casting, includes processes such as pressing wax, wax repairing, tree forming, dipping, melting wax, casting molten metal, and post-processing.

Sand Casting is a widely used form of casting. As the name suggests, the mold is made from sand. Sand Casting requires placing a finished part model or a wooden model (pattern) in the sand, then filling the sand around the pattern, and taking the pattern out of the box to form a mold. So what is the

The surface of the wax mold is covered with a layer of refractory ceramic material. Once the ceramic material hardens, the desired casting geometry is formed inside it, and then the wax is melted and exported, and the cavity is filled with molten metal. After the metal solidifies in the ceramic mold
