Casting for Pipe Casting for Locomotive Accessories Casting for Construction Machinery

We can supply all kinds of casting and machining parts,casting steel and casting iron parts,water glass casting parts,silicasol casting,investment casting,precision casting parts,sand casting parts and different sizes of magnetic track brake bracket ,tumbler support,center pin,locating swing arm for railway bogie, coupler top lock lifter, coupler bottom lock lifter, short neck couplers, long neck couplers,coupler knuckles Locks and yokes for railway bogie.

Q: Casting blank in the cooling process to release a large amount of heat energy, what can be recycled?: Casting, do not need to provide a rough casting foundry drawings, according to your chart will put foot margin in the processing needs of the surface, the rest of the size can be found according to the mechanical design manual and manual casting. General Casting Factory Casting Division will be in your chart marked on shrinkage and processing margin figure (usually with red and green pen) to the patternmaker production of wood or other material mould diagram.

Q: our factory now produces steel castings in the use of polishing directly after spraying processing, but the powder sprayed 15But the spray powder touched off what is the reason we are not very strict requirements not only need to peel off bubbles can also, because our products are steel castings so we use steam hole sludge put on. Do not know if this spray treatment has no effect to thank friends with us!: Usually after rusting,Did you peel it?If it isNeed to do film processingIf notPlease look for the coating factoryBetter paint (such as epoxy ester, etc.)

Q: Is the cast steel a casting part?: Cast steel is divided according to material, as well as cast iron parts, cast aluminum parts and so onCasting parts are divided according to the method, as well as forging partsCast steel parts must be casting parts

Q: What kind of casting process is used for cast iron parts? And what are the cast steel parts adopted?: Corundum sand: the main mineral composition is corundum alpha -Al2O3, used for investment casting, ceramic mold casting shell materials. The olivine sand: the main mineral composition of olivine (MgFe) 2SiO4, used in cast iron, non-ferrous alloy castings and high manganese steel casting molding sand and the core sand. Silica resources in nature resources, but suitable for casting with high SiO2 content of natural silica sand is not too much. Since 1951, China has carried out a general survey of the casting sand resources in the territory, but mainly limited to the main traffic lines and major industrial cities. Survey results show that Chinese can be used for natural silica sand casting is very rich in resources, a wide range of distribution. Inner Mongolia Zhelimumeng, natural silica sand reserves amounted to hundreds of millions of tons, the particle shape close to the circular, the content of SiO2 is about 90%. Fujian, Jinjiang Dongshan sea sand, the content of SiO2 is 94 to 98%, with a low volume of mud, are good natural silica sand. Are Duchang, Yongxiu Jiangxi County Xingzi, a large number of Quaternary lacustrine deposition of silica sand, the content of SiO2 is about 90%, low iron content, alkaline oxide less, uniform size, is a good lake sand. Guangzhou, Hunan and other places have abundant easily broken weathered sandstone, processing artificial silica sand, the content of SiO2 in more than 96%, can be used for the production of steel castings. Jiangsu Nanjing red sand, sandy mud pure, moderate, strong permeability, good viscosity, high silica content, less water, fine particles, pulls out the casting is smooth, stable quality, can be made of cast iron and non-ferrous metal parts of the sand and core sand

Q: For example, casting parts contain many holes, inclusions and other defects, the size and the number of holes exceed which limit is not qualified: According to different casting process and parts materials, each has relevant standards, can be found online;

Q: What is the difference between casting and stamping parts?: Cold stamping is generally no longer done by cutting, or only a small amount of cutting is required. The precision and surface state of hot stamping parts are lower than those of cold stamping parts, but they are better than those of castings and forgings, and the amount of cutting is less.Stamping is mainly based on process classification, can be divided into separation process and forming process two major categories.

Q: As shown, how do I achieve the tightness test of this product, and achieve industrial production? Seek expert advice.: Precise and tight sealing of the surface to which the test piece is to be tested, equipped with an airtight test instrument, and an electrical control system. You can complete automated testing equipment

Q: What are the general technical requirements for casting parts?: What kind of casting do you want to know? Copper parts, iron pieces, aluminum pieces??? Their casting conditions are different.

Q: How to solve casting defect casting?: Prevention methodReduce the gas in the metal liquid and oxidize the slag, improve the fluidity of the metal liquidIncrease pouring temperature and pouring speed, strengthen slag collection, slag block or bottom pouring bag, teapot ladle pouring, can not cut off when pouring, prevent the slag from blocking the nozzle, and cause the casting to breakIncrease the sprue and sprue height, increase the runner section area and the sprue number, and improve the filling speed and the metal hydrostatic headImprove the casting design and increase the thickness of the thin-wall part of the castingChange the pouring position and pouring system, the casting thin wall plane is located at the top and away from the gate, to prevent the filling of liquid metal splashing, eddy current, avoid metal stream in the casting thin sections or core support, cold iron, insert the confluence, when necessary, take horizontal vertical pouring cold or inclined castingIncrease the permeability of core and sand, strengthen the exhaust of mould, and the quantity of air outlet and riser should be enoughChange the size and location of the core, the inner cold iron, the core support, the internal cold iron, the insert should be no rust, no oil pollutionCheck the type, tight box, press the operation of iron is safe, to prevent running fire
