Q: How to calculate the price of casting parts?: According to the complexity of the workpiece, material and casting requirements and process yield

Q: What's the effect of casting copper?: Riga. Copper is copper components, promote the graphitization of the copper element, make dense tissue, and to refine and improve the uniform distribution of graphite, which can reduce the chilling tendency of the cast iron, but also can promote the formation of pearlite, has a favorable effect on the section sensitivity. Copper has the tendency to strengthen cast iron, ferrite and pearlite, so it can increase the strength of cast iron. The tensile strength and bending strength of cast iron almost increase with the amount of copper in it, especially in low carbon cast iron.

Q: Explain the heat treatment effect of casting parts, forging parts and welding parts: The three methods of metal processing have one thing in common. They are hot working, which are different in temperature and range of processing. Ductile cast iron is widely used because of its brittleness and poor impact. Heat treatment of cast iron usually adopts the annealing process, reduce the casting effect: 1 because of the internal stress caused by the thermal expansion and contraction, reduce the deformation after machining, decrease surface hardness, improve machining conditions;

Q: Does anyone know how to make precise casting parts for aerospace or manufacturers of single and small quantities of automotive parts and components, mainly in Beijing, Tianjin and Tangshan?: List of China's military enterprises list of ten major military groupsChina Nuclear Industry Construction Group CorporationChina Aerospace Science and Technology CorporationChina Aerospace Science and Engineering CorporationChina Aviation Industry CorporationChina Aviation Industry Corporation IiChina State Shipbuilding CorporationcsicChina North Industries Group CorporationChina South Industries Group CorporationChina National Nuclear CorporationKey military enterprisesShipbuilding industry:China State Shipbuilding Corporation (South ship group), (China Shipping Group)China Shipbuilding Industry Corp (North Ship group), (China Shipbuilding Industry)Guangzhou Shipyard International Limited by Share Ltd (GSI)Jiangnan Heavy Industry Limited by Share Ltd (Jiangnan Heavy Industry)Nuclear industry:China National Nuclear Corporation (CNNC)China Nuclear Industry Construction Group Corporation

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: 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 kind of flaw detector is better for casting parts?: Casting using the detector test, you must first determine the detection process, such as the detection of surface and near surface crack defects, such as casting, recommended by CYD-3000, or CYD-5000 mobile magnetic testing machine for testing.

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: Lathe processing stainless steel casting parts to use what type of tool, the speed into the amount of how much tool angle: It has something to do with the size of your work, and it has a lot to do with the blade you're using right now.
