- Q: Why does the precision casting factory not usually make iron castings?
- Because it is too cheap, the design of materials is cast iron, generally do not have very high requirements.
- 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: 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!
- Usually after rusting,Did you peel it?If it isNeed to do film processingIf notPlease look for the coating factoryBetter paint (such as epoxy ester, etc.)
- Q: What are the requirements for casting steel castings?
- 4 thickness, most should be placed above the.5 and try to reduce the number of.6, the sand core should be used in classification of flat surface
- Q: How do casting parts remove stress?
- Annealing treatment, according to different casting annealing treatment, eliminate thermal stress, if need to restore hardness or increase hardness, and then quenching treatment
- Q: After reaming, the roughness can reach several levels, that is to say, the sample.Casting parts in rocker arm drilling, reaming, roughness, block. After reaming, the roughness can reach several levels, that is to say, the sample.
- Not processed, do not understand your problem... There's something wrong with the drilling machine. Please call me
- 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: 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: What is the difference between casting and stamping parts?
- The purpose of forming processes is to allow the sheet to undergo plastic deformation without breaking the billet and to make the desired shape and size. In actual production, a variety of processes are often applied to a workpiece. Blanking, bending, shearing, drawing, bulging, spinning and rectification are several main stamping processes. The difference between stamping parts and castings: with thin, uniform, light, strong features, stamping can be produced by other methods difficult to make, with stiffeners, ribs, UPS or flanging of the workpiece, to improve its rigidity. Due to the use of precision molds, the workpiece accuracy up to microns, and repeated high precision, specifications consistent, you can punch out of the hole, lug and so on.
- 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.
