FAQ

1. How about your price?

A:As one of famous manufacturers of Ductile iron products inChina, Our prices are very favorable and competitive. The customers from all-over the world.

2.How about your time of delivery?

A:Within in 30 days after the order is concluded.

Q:What kind of casting process is used for cast iron parts? And what are the cast steel parts adopted?: The main content of red sand table (Institute of soil science, China) silica 79.4%. three 1.48%. three 10.55%. two aluminum oxide iron oxide, calcium oxide 0.85%. Magnesium Oxide 0.52%. 1440. refractory mud 3.06% LOI 1.98% red sand with high silicon content, permeability is strong, durable, high refractoriness, good angle, low moisture content, less mud the casting finish is high, the basic requirements of sand should meet the following requirements: Casting of high purity and cleanliness, with silica sand as an example, iron sand SiO2 content of more than 90%, the big steel casting requests the SiO2 content of more than 97%; the high refractoriness and thermal stability; the suitable particle the shape and particle composition; it is not easy to be wetted by the liquid metal; cheap. The particle shape and composition of casting sand particle shape and particle composition permeability properties such as mobility, sand compaction, permeability, strength and resistance to liquid metal effects, is an important indicator of the quality of casting 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:Why do cheap cars like stamping parts instead of casting parts?: We usually say that the stamping is usually refers to the cold stamping parts, for example, a piece of iron, wants to turn it into a fast food dish, it must design a set of mold, mold is working face plate shape, the pressure plate mold, it becomes you want the dishes, this is the cold stamping die stamping is the direct use of metal materials.Automobile stamping parts are mainly classified according to process, and can be divided into two major parts: separation process and forming process.

Q:What are the factors affecting the machining process of the casting material and structure?: Medium carbon steel begins, and the casting can not be punched and tapped directlyStainless steel, ordinary grade (Fe based alloy element content, less) can not do heat treatment. But processing small holes or tapping to heat treatment (solution. In practice, the annealing treatment can also be). There are a lot of stainless steel matrix is not to say, for example, nickel, cobalt and tungsten. And so on.

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 can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness: Hot galvanizingGenerally 0.06 mm or more

Q:Casting parts need to be subjected to the kind of heat treatment after the weldment is finished: This is difficult to say, the key is to see the specific parts and components, the final mechanical performance requirements.For example, gray cast iron, usually graphite annealing, to heat treatment annealing, surface quenching and so on, ductile iron can be a variety of annealing, normalizing, quenching and isothermal quenching, surface treatment, chemical treatment and so on, in a word, heat treatment of steel can usually, nodular cast iron can do. Malleable cast iron and vermicular cast iron are often subjected to graphitization annealing and stress relieving annealing, while wear-resistant cast irons often undergo quenching + low temperature tempering, and so on.Welding is the case, such as bearing steel welding must be quenched + low temperature tempering, machine spindle welding (repair welding) must be quenched and tempered treatment, and so on. Of course, if it is a general weld, there is no need for heat treatment or, at most, stress relieving annealing.

Q:What do you mean by "proofing" in the casting? Do you charge for the proofing?: Die die must charge, wood cheap, expensive aluminum mold

Q:The cause of fracture and why there is no toughness: This question is too broad, see what the casting casting Oh in order to reduce the wayward cast steel, ductile iron, gray iron and white iron, you can choose the material according to their own requirements.

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
