H2. 1.Process planning:Strictly control the process, before the tanks, to ensure that the appearance and the sand core is with temperature condition, to ensure when pouring molten steel liquid, on appearance coarse broken place choose luck gentleman family ISOMOL300 alcohol-based zircon powder coati

When a casting solidifies, with the decrease of temperature, the casting will become solid in this process will occur phase transformation, as the casting into solid phase transformation process, phase transformation will also occur shrinkage or expansion process, due to the existence of a thicker o

H2. The analysis and research on casting defects is one of the key techniques to improve the casting yield. However, the difficulty is not small.H3. Main performances:1.It covers a wide range of knowledge, such as alloy, casting process, molding material, casting equipment and testing of production

H2. 1.Holding timeThe length of holding time depends on the precision casting material and wall thickness.For castings with high melting point, high crystallization temperature range and thick wall, the holding time is longer.For the casting of small and thin wall of crystallization temperature, the

H2. Precision casting is a casting process with less cutting or no cutting, which is an excellent technology in casting industry. Its application is very wide, not only is applicable to various types, various kinds of alloy casting, and produce the casting dimension accuracy and surface quality is h

H1. The following is to explain the process of precision casting wax molds：H2. 1.process operation:When repairing any kind of precision casting wax molds, the waxing personnel first make clear which part should be repaired.Check whether the wax model has bubbles, indentation, deformation and other d

Stainless steel precision casting for use in the process of its mechanical properties is relatively high, mainly due to the melting point of the product is higher, stainless steel precision casting of easy oxidation of liquid steel, illiquid and contraction of the molten steel at run time, volume sh

When it comes to precision casting, many friends must think that they can only make some simple parts with metal.In fact, there is more learning in it.And precision casting is one of the precision equipment that is used in many places nowadays. There are several kinds of light casting types, so let'

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
