Precision casting structure design should accord with the requirement of machine equipment itself and mechanical processing manufacturability requirements, should also meet the requirements of the casting process, casting structure design should pay attention to the following points：1. To facilitate

The precision casting is a fusible model made of fusible materials,It is coated with several layers of special refractory coatings, which are dried and hardened to form a monolithic shell, and then melt the model from the shell with steam or hot water.The shell is then placed in a sandbox,dry sand a

Sand type precision casting is preferred.According to statistics, in our country or international, in total casting production, 60 ~ 70% of casting is made of sand,and about 70% of them are made of clay sand.The main reason is that sand casting is cheaper than other casting methods、the production pr

The stainless steel precision casting temperature can effectively guarantee the fluidity of the melt in the process of transfer.In the process of temperature selection of stainless steel precision casting, some factors such as the distance of the transfer and the cooling conditions and the flow rate

Explain the difference between precision casting and ordinary casting.H2. Precision casting is to pour the liquid metal into the casting mould with the same shape as the parts. When the casting is cooled, our precision casting products can be formed.The casting methods include sand casting, special

In the process of using stainless steel precision casting, its temperature can guarantee that its melt has good fluidity in the process of transfer，In the process of selecting temperature, the stainless steel precision casting needs to be determined according to the distance of the transfer and the

Defect characterization：The surface of the zinc alloy precision casting is made up of small blister, which can be found, polished or processed after being exposed, sprayed or electroplated. Causes: It is mainly the stoma and contraction mechanism, the stoma is usually round, and the contraction most

Precision casting technology can be summarized in developed countries to protect the environment, improve casting quality and reliability, reduce production cost and shorten delivery time.Ductile iron casting technology as an important part of casting technology, research on ductile cast iron castin

The sulfuric oxide film of stainless steel precision casting is an important factor to influence the high purity and transparency of the oxide film of stainless steel castings. The porosity, purity, thickness and sealing quality of stainless steel precision casting can directly interfere with the mi

What is the Treatment of Surface?Surface treatment is a process of forming a surface layer on the surface of the matrix material, which is different from the mechanical, physical and chemical properties of the matrix.
