Investment casting process for long hole and narrow slot castings

The investment casting shell is a repetition of the process of "coating-sand-drying. However, for castings with long holes and narrow grooves, it is difficult to cast them when the ratio of hole depth to hole diameter H/d>5, and the ratio of groove depth or length to width of narrow grooves is greater than a certain proportion, which is often realized by mechanical processing. For long holes with slightly larger diameter, although the shell can be made, it has been filled with slurry and sand, increasing the probability of shrinkage and porosity defects. Today, Yufeng metal, a precision casting manufacturer, discusses several methods of investment casting for this kind of castings.

What are the defects of the group tree of investment casting?

The investment casting group tree process is actually composed of two processes. These two processes are assembly and welding, because sometimes the wax piece is not a gate, need to be homemade or pressed, and then bonded with the wax piece, and finally connected with the gating system. In these two processes, defects in the tree formation process may occur. Today, Yufeng Metal, a precision casting manufacturer, will talk about the defects in the tree formation. Assembly needs size to ensure, then, the size is inconsistent or the size does not conform to the process documents is its defect; welding must also have welding quality, then, poor welding is the welding defect.

What is running fire in precision casting

Running fire generally occurs in sand casting. After checking the Investment Casting Manual, there was no such defect as running fire. However, there are running defects in the two books "Handbook of Casting Defects and Countermeasures" and "Practical Investment Casting Technology" compiled by Jiang Bju, and both are under the details of investment casting defects. Today, Yufeng Metal, a precision casting manufacturer, will talk about what causes the fire. Running fire, as the name implies, is the fire ran out. The fire here actually refers to high-temperature molten metal. Because the temperature of the molten metal is high, it is similar to fire in terms of color and temperature, so the word "running fire" came into being. Since it can run fire, it means that the shell has a channel for running fire, that is to say, the strength of the shell is not enough, which creates an opportunity for the metal liquid to escape. So, what are these channels and what are the causes?
