Q:ZGMn13 casting parts processing, with what knife head good?: The ZGMn13 itself is not have processing, if only the processing point, sharpening, ordinary can, if the processing area is relatively large, ZGMn13 external impact load is bigger,

Q:Is the cast steel a casting part?: Yes, molten steel is poured into the mold and cooled to become a casting. Can also cast iron, cast aluminum, plastic 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: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: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: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: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:What's the cause of the choking of the casting?,: 2. when casting mold exhaust condition is not good, in the casting material use consider whether and hinder its gas permeability; in the process to consider to release more pores, multi venting; core exhaust is particularly important.
