Q:Casting parts, anodizing 20
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:What's the effect of casting copper?
In general cast iron, the mass fraction of copper below 3% - 3.5% can increase the hardness; but when the cast iron has a tendency to chill, or when there is a hard point of free carbides, the addition of copper decreases the hardness.Copper can be used to improve the wear resistance, abrasion resistance, and shock absorption of cast iron, so it is often used in the manufacture of sliding friction iron castings, such as drilling machine spindle, automobile and tractor, valve tappet, etc.. But in white cast iron or chilled cast iron, adding copper does not make any improvement in its abrasion resistance.Copper for certain heat resistant cast iron and austenitic cast iron can increase the heat resistance and corrosion resistance, copper - chromium composite alloy to prevent oxidation under high temperature in the atmosphere from the skin effect is particularly effective, heat resistance and corrosion resistance of austenitic cast iron containing many mass fraction of 4% ~ 7% copper.
Q:What are the general technical requirements for casting parts?
According to the national standard GB/T 9438, there are 8 aspects: 1. chemical composition; 2. delivery status; 3. mechanical properties; 4. dimensional tolerances; 5. weight tolerances; 6. appearance quality; 7. internal quality; 8. casting salvage.
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:Why does the precision casting factory not usually make iron castings?
The so-called precision parts is the size, roughness requirements of the piece. Cast iron parts generally do not reach the accuracy.
Q:What are the causes of pitting on the surface of a precision casting?
The quality of the shell surface is out of order. Or shot blasting out of question.
Q:How to solve casting defect casting?
Prevention methodReduce the gas in the metal liquid and oxidize the slag, improve the fluidity of the metal liquidIncrease pouring temperature and pouring speed, strengthen slag collection, slag block or bottom pouring bag, teapot ladle pouring, can not cut off when pouring, prevent the slag from blocking the nozzle, and cause the casting to breakIncrease the sprue and sprue height, increase the runner section area and the sprue number, and improve the filling speed and the metal hydrostatic headImprove the casting design and increase the thickness of the thin-wall part of the castingChange the pouring position and pouring system, the casting thin wall plane is located at the top and away from the gate, to prevent the filling of liquid metal splashing, eddy current, avoid metal stream in the casting thin sections or core support, cold iron, insert the confluence, when necessary, take horizontal vertical pouring cold or inclined castingIncrease the permeability of core and sand, strengthen the exhaust of mould, and the quantity of air outlet and riser should be enoughChange the size and location of the core, the inner cold iron, the core support, the internal cold iron, the insert should be no rust, no oil pollutionCheck the type, tight box, press the operation of iron is safe, to prevent running fire
Q:What is the difference between the casting drawing and the car work drawing?
Casting rough drawings generally no processing symbols, processing drawings indispensable is processing symbols!
Q:Selection of hydraulic press is the casting parts and steel plate welding, how to choose?
Casting parts in one shape, the overall processing in this regard than steel plate welding better. The same price is much more expensive than steel. Large hydraulic presses seldom have casting parts.
Q:Heat treatment process and purpose of casting parts
Objective: to stabilize tissues, eliminate or substantially reduce internal stress.
