Tenfaye formulates the process flow according to customer needs and sends it to the workshop, which arranges the casting process according to the drawings.
The first is wood mold making. The mold is produced according to the drawings. After the wooden mold is completed, the workshop begins to mix sand to prepare for the next step of modeling. The old sand and new sand are mixed in proportion and an appropriate amount of clay is added for mixing.
The second step is to shape the pit. This stage includes the casting cavity made of molding sand, core making of the casting (the internal shape of the casting) and mold matching (putting the core into the cavity and closing the upper and lower flasks). The shape is steel casting casting. key link in the process.
The third step is molten steel smelting. After the required metal components are prepared, they are put into the melting furnace for melting to form qualified liquid metal;
The fourth step is pouring. Use a ladle to inject the molten iron into the mold. When pouring the molten iron, you need to pay attention to the pouring speed so that the molten iron fills the entire cavity.
The fifth step is to clean the castings. After pouring and waiting for the molten metal to solidify, remove the gate and shake off the sand from the casting, and sandblast with a sandblasting machine. Casting blanks with less stringent requirements can basically be shipped out of the factory after inspection. If special requirements are required, simple processing can be performed.
The sixth step is to inspect the castings. Generally, non-destructive testing is used to inspect the steel castings.
