Q:General aluminum alloy die casting or casting box and other parts,
Aluminum alloy die-casting parts or casting box and other parts of the threaded hole, in the case of processing conditions, it is best to use wire tapping or machine tool processing! Direct casting is not advocated.
Q:Younger brother is to do casting valve, precision casting parts, the valve internal sand serious, but the appearance is very standard, this is why, for God answers, thank you!
Valve sand core mold drying is not in place, excessive water content
Q:How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness
Hot galvanizing doesn't seem to workThe zinc layer is 275g/ square meters of material coating is 0.019mm (mm), up to 0.08 thick.
Q:What's the density of casting?
Generally cast iron thick place, density is empty, thin place density a little more.
Q:The difference between cement sand castings, resin sand castings and vacuum casting parts
Vacuum casting is the process of using ventilation molds. Molten metal flows into the mold by air pressure, and then removes air to form a vacuum. The casting process is mainly used for small parts or jewelry with exquisite detailsCompared with the traditional clay sand casting, heat hardening resin sand casting production with low surface roughness, high precision, good quality characteristics, dimensional accuracy of resin sand mold after hardening with good rigidity and high, and not easy to deform, so in the choice of process parameters, mechanical processing you can select a smaller margin, thereby reducing the consumption of metal solution and machining cost, which can improve the dimensional accuracy of castings.
Q:How to distinguish the forging parts and casting parts accurately
To distinguish from the use of materialsForging materials are mainly made of carbon steel and alloy steel of various components, followed by aluminum, magnesium, titanium, copper and their alloys. The original state of the material is rod, ingot, metal powder and liquid metal. The materials needed for casting are mostly metal, wood, fuel, molding materials and so on. In contrast, the forging parts rarely produce dust, harmful gas and noise, etc., and play a more obvious role in environmental protection. Of course, because of this, the price of forged parts on the market is higher than that of castings.
Q:When the blank is a casting, the margin is evenly distributed, how should rough machining? Twenty
Even distribution is a good thing. Generally, the machining allowance of the casting is uneven.If the processing depends on how your processing techniques have been arranged.In the NC milling plane contour machining, when the rough margin is large, how to deal with.1. Return to the foundry, too large margin improvement.2. Then you can spend more time on it.
Q:What is the reason for 304 stainless steel precision casting parts to be changed?
Mainly because of the cooling shrinkage caused by internal stress caused. There is the change of temperature distribution in materials element imbalance, is typical of surface and internal, thin wall and thick wall, bottom and top.
Q:Where is the precision casting factory?
The National Precision Casting Factory is generally distributed in Shandong, Ji'nan, Jiangsu, Wuxi, Changzhou, Zhejiang, Guangdong, Panyu, Dongguan.The above are only the main distribution, many of Shandong are made supercharger, and Guangdong to jewelry industry based.
Q:Explain the heat treatment effect of casting parts, forging parts and welding parts
2 improve the crystal structure, enhance the formation and stability of spherical carbon crystal;Forgings are generally stress bearing members, and most of them are made of high strength medium carbon steel (alloy), which is formed by forging and fine crystalline. After the shell is annealed or quenched and tempered, the mechanical properties of the shell are more superior, and it has better strength and better elasticity;Welding materials.
