Q: How is the silicon sol precision casting part priced? What is the price per ton of casting? Such as 304 material.: The material is usually steel material price plus the cost (per ton of 2.5-3 million, plus profit).In the Yangtze River Delta region, generally 304 casting price of about 5-5.5 million / ton.The price will be higher if the parts are complex, or a piece weighs less than 100 grams.

Q: How to improve the surface roughness of casting parts?: One is to improve the accuracy of the model; the two is to improve the molding sand mesh. How much is the other relationship?.

Q: What are the requirements for casting steel castings?: 1, high quality requirements of the surface or the main processing surface should be placed below.

Q: In theory, which is more expensive, forging parts or casting parts?: The structure of the casting is relatively flexible in design, and the modeling is easy to realize.

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 kind of flaw detector is better for casting parts?: If you want to detect internal defects, you can use ultrasonic flaw detector, ray flaw detector can also, but the ray of the safety protection level is too high, not recommended priorityMacro Xu flaw detector answered, such as the magnetic particle inspection machine has the demand can contact us, Baidu "macro Xu flaw detection""

Q: Which surface is coarser for cast iron or cast steel castings? Why?: Roughness mainly depends on the surface roughness on the surface of the sand.

Q: My parts complex, machining costs are relatively high, so want to cast, but the surface needs anodizing, what material will be better?: The common material that can be anodized is aluminum alloy. It is recommended to use casting aluminum alloys, such as ZL102 and ZL105, which are commonly used as cast aluminium alloys. The processing of aluminum casting is easy. After processing, the surface of the whole part can be anodized. The color can be chosen.

Q: When there is no flaw detection for large casting parts, is there any crack inside?: According to the industry standards, within the scope of the standard requirements to determine whether the product is qualified
