What factors will affect the quality of hydraulic castings? As for machine tool cast iron, people engaged in this industry may have a better understanding of it and know where its advantages are. They can handle any troubles in the operation process without professional repair. However, people who have just engaged in this profession may not know how to operate this profession and can only reduce problems according to its process. However, this does not mean that the products produced according to its process are of good quality, so, hydraulic casting factory in the casting processing, what factors will affect the quality of hydraulic castings?

As for machine tool cast iron, people engaged in this industry may have a better understanding of it and know where its advantages are. They can handle any troubles in the operation process without professional repair. However, people who have just engaged in this profession may not know how to operate this profession and can only reduce problems according to its process. However, this does not mean that the products produced according to its process are of good quality, so, hydraulic casting factory in the casting processing, what factors will affect the quality of hydraulic castings?

Generally speaking, hydraulic casting manufacturers will establish models and prepare data according to existing models. They believe that the accuracy of gravity casting precision castings and the economy of the entire production process mainly depend on the influence of the casting process. The production center of many modern casting workshops is machining or automation. However, sand removal from precision castings is a process with poor working conditions. Therefore, when hydraulic casting factories choose the modeling method, the convenience of on-site sand cleaning should also be considered, and the hydraulic casting plant should be required to heat treat the special requirements of precision castings.

Due to the large volume and composition of precision casting, the types of aluminum alloys are almost unlimited. These castings have general mechanical functions, wear resistance, corrosion resistance and other induction functions, as well as other aluminum alloy forming methods, such as casting and welding. Therefore, in the machinery manufacturing industry, the number of billets produced by casting is still very large. After pouring high-temperature aluminum alloy liquid into the mold, the mold is filled with a lot of gas, these gases need to be gently discharged from the precision casting mold. It is similar to the nature of sand that allows gas to pass through, that is, air permeability. These parts have defects, such as insufficient hole space, fine grain size of sand, large water content of clay, sand mold, The higher the water content, the lower the water content.

Discussion on Heat Treatment of Precision Castings

Due to the different intentions of precision castings, there are many kinds of heat treatment, which can be divided into two categories. The main one is that the arrangement structure will not change after heat treatment, and may not be changed. In fact, the basic arrangement structure has changed. The heat treatment program is mainly used to eliminate internal stress, which is caused by different cooling conditions and conditions during stainless steel casting, alignment, strength and other mechanical properties will not be significantly changed by heat treatment.

Regarding the second type of heat treatment, the basic layout has undergone significant changes, which can be roughly divided into five categories:

1. Softening annealing: Its purpose is mainly to differentiate carbides, reduce its hardness, and improve processing performance. As far as ductile iron is concerned, its purpose is to obtain more ferrite arrangements.

2. normalizing: the main purpose is to obtain pearlite and sorbite arrangement to improve the mechanical properties of stainless steel castings.

3. Quenching treatment: The main purpose is to obtain higher hardness or wear resistance, and at the same time achieve very high appearance wear resistance.

4. Surface hardening treatment: The first step is to obtain a surface hardening layer while obtaining high surface wear resistance.

5. Precipitation hardening treatment: The main purpose is to obtain high strength without drastic changes in elongation.
