What are the main uses of precision casting?

Precision castingThe main purpose of the product is becoming more and more common, and the production and processing technology is becoming more and more. The whole process of refrigeration is an indispensable whole process. Some of them must personally experience the solid phase change of the aluminum alloy profile, and the metal changes during the change period, for example, the volume of carbon steel changes fromThe δ phase becomes the γ phase, and the volume increases when the eutectoid of the γ phase is transformed.

In the stainless steel precision casting processing technology, the most common production and processing method is precision casting production and processing, but irregular operating procedures generally endanger the final quality of the castings, so what should everyone pay attention to in the operating procedures?

In the production process of precision casting, due to some hardware facilities, management methods, pouring refrigeration and calibration problems, the problem of casting deformation will be caused, so how do we solve the problem of casting deformation?

The deformation of castings is divided into: minor self-deformation, expansion deformation and expansion and contraction deformation of castings.

Small amount of self-deformation: Among alloy products, steel castings are most prone to small amounts of self-deformation. After the falling sand of the steel casting is removed, the remaining residual stress is mainly the residual welding stress. In addition to the shortcomings of cold cracking and casting deformation caused by the forging, the residual stress is also the key reason for the small amount of self-deformation. Even if the residual stress does not exceed the tensile strength of the raw material, under its effect, the steel casting will slowly produce a small amount of plastic deformation with the continuation of time. This type of deformation is called a small amount of self-deformation.

Regarding this series of problems, we have learned about some large and medium-sized stainless steel casting manufacturing industries. The sales market of the stainless steel casting manufacturing industry is mainly based on the precise positioning of the manufacturing process.
