Casting Process Design of Iron Castings

The cast iron casting process involves the process design of iron casting itself, the design of the gating system, the design of the feeding system, the design of the exhaust port, the design of the chill system, and the special design. Cast iron casting process, etc. Next, let's take a look at the design of the cast iron casting process.

The process design of the part itself of the Cast iron casting process

The process design for cast iron casting is a comprehensive and multi-faceted task. It involves meticulous planning to ensure the final product is both dimensionally accurate and structurally sound. Key aspects of this design process include:

• Determining the necessary machining allowance for the finished part.

• Selecting the optimal pouring position and parting surface to facilitate mold filling and part removal.

• Defining specific casting parameters such as dimensional tolerances, shrinkage rates, and draft angles.

• Designing corrections for potential issues, including adjustments for shrinkage and other factors that could impact the final dimensions, material quantity, and part type.

Cast iron casting process casting system

The casting system of the Cast iron casting process is a channel that guides the molten metal into the mold cavity. Whether the casting system of the Cast iron casting process is designed reasonably or not, it has a great impact on the quality of iron casting and is likely to cause various types of casting defects. For example insufficient pouring, cold barrier, sand-washing, slag inclusion, inclusions, sand inclusions, and other casting defects. The design of the gating system of Cast iron casting process includes the selection of the type of the gating system, the selection of the position of the inner gate, and the determination of the cross-sectional dimensions of each component of the gating system of the Cast iron casting process. In addition, the choice of Cast iron casting process gating system is also very important, so how can we choose the correct Cast iron casting process gating system?

Nowadays, to facilitate production and ensure the quality of iron casting, the inner runner of the Cast iron casting process casting system is generally set on the parting surface of the iron casting mold. According to the pouring position of the iron casting blank and the selection of the parting surface, the inner runner opened on the parting surface of the iron casting mold belongs to the "medium casting" gating system. Liquid metal will inevitably contain a certain amount of "slag" during the casting process. To improve the slag retaining ability of the casting system of the cast iron casting process, a "closed" casting system should be adopted. In the cast iron casting process, the design of the cast iron casting process has a great influence on the quality of the cast product, but the choice of the casting system selection method of the cast iron casting process cannot be ignored.

Feeding system of Cast iron casting process

The design of the feed system of the cast iron casting process is an engineering technology of rational design of risers and subsidies to compensate for the shrinkage of liquids and solids produced in the solidification process of iron casting to obtain a good iron casting. The vent hole of the cast iron casting process feed system is used to discharge the gas in the cavity, improve the filling capacity of the molten metal, remove the scum of the supercooled molten metal and the first filling of the cavity, and can also be used to observe whether the cavity is full Logo.
