Q:The difference between cement sand castings, resin sand castings and vacuum casting parts
Our country or international, in all casting production in 60 ~ 70% by sand casting is produced, of which about 70% is used in the production of clay sand. The main reason is that the cost of sand casting is low compared with other casting method, simple production process and short production cycle. So as the car engine cylinder body the cylinder head, crankshaft castings are produced using clay wet sand molding process. When the wet type can not meet the requirement to consider the use of clay sand table dry sand, dry sand mold or other sand.
Q:Is 316 casting better than 304 casting?
The degree of difficulty in the process of casting depends mainly on the structure, precision requirements, and hardness of the casting. It is comprehensive. There is no simple comparison of the material to determine the degree of difficulty in processing
Q:What is the difference between casting and stamping parts?
Separation process is also called blanking, the purpose is to make the stamping parts along a certain contour line from the sheet metal separation, at the same time guarantee the quality requirements of the separation section. Stamping is a highly efficient production methods, the use of compound die, especially the multi station progressive die stamping process can be completed in a multi machine, realized by belt uncoiling, leveling, punching, forming and finishing automatic production. High production efficiency, good working conditions, low production costs, can produce hundreds of parts per minute.
Q:What are the casting parts used to test shrinkage holes?
1. anatomy. It is easy to slack off by sawing and machining.
Q:My parts complex, machining costs are relatively high, so want to cast, but the surface needs anodizing, what material will be better?
Yes, the cast aluminium is polarized and gray, but the key problem is to guarantee the quality of the aluminium casting, and the quality of the other aluminium casting is not good.
Q:Would you please tell me how to use casting parts for a year?The cast of an aircraft wing needs to be put aside for a year before it breaks;Does anyone know why?
There are various casting stresses after casting, which can be divided into two kinds: thermal stress and shrinkage stress. In a long time placed in the atmosphere, called aging treatment.Aging treatment is an effective measure to eliminate casting stress. Aging is divided into natural aging, thermal aging and resonance aging.1, the so-called natural aging, the casting is placed in the open field for more than half a year, so that the internal stress relief.
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: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?

Q:our factory now produces steel castings in the use of polishing directly after spraying processing, but the powder sprayed 15But the spray powder touched off what is the reason we are not very strict requirements not only need to peel off bubbles can also, because our products are steel castings so we use steam hole sludge put on. Do not know if this spray treatment has no effect to thank friends with us!
You oily sludge!Is not the general market on the soil?If it isPlease use two groups of chemicals to reinforce the soilOr suggest your company?Do the putty or paint film after doingThat's better
Q:How to improve the surface roughness of casting parts?
First, the accuracy of the model should be improved; two is to change the molding technique; the three is the coating; and the worker's technical level.
