      YES!  We are a professional ductile iron &gery iron casting  Factory in China.
2.Q: How long can you make your quotation:
        Within 3 workdays after received your detailed product information
3.Q: Do you provide OEM Service?
       Yes, we provide OEM Service.

Q:Shandong foundry, casting small pieces of precision casting
Dongying Huayang precision casting factory, the smallest to do 2G pieces.
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:Why does the precision casting factory not usually make iron castings?
Jiangyin Lin Xing stainless steel (precision manufacturing) Co., Ltd. to provide professional precision casting
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:Casting parts have poor surface finish. What sand is used to make them?
Manual coal dust, clay sand is a little worse. Mechanical styling is not bad either.
Q:The casting defects of pores, trachoma how to repair?
Airhole above 2mm recommended LT101 casting defect repair agent. If repair quality requirements, high availability LT111 iron repair agent, LT112 steel repair agent, LT113 aluminum repair agent, LT114 copper repair agent.
Q:Heat treatment process and purpose of casting parts
Natural aging (also known as Chang Hua): lost in the open, the sun and rain, can have experienced years of wind and frost.
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:What are the general technical requirements for casting parts?
Satisfy appearance quality (appearance defect, quality change, size deviation)Intrinsic quality (composition, properties, internal organization)Service performance (abrasion resistance, corrosion resistance, heat resistance, pressure resistance)
Q:What are the casting parts tested?
The surface brightness, appearance, size, chemical composition, weight, material, surface defects, internal defects, seals need to be checked, leakage, etc.
