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. Can I get free samples?
A: Yes, we can provide the free samples, but you need to bear delivery freight.
- 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: Explain the heat treatment effect of casting parts, forging parts and welding parts
- 2 improve the crystal structure, enhance the formation and stability of spherical carbon crystal;Forgings are generally stress bearing members, and most of them are made of high strength medium carbon steel (alloy), which is formed by forging and fine crystalline. After the shell is annealed or quenched and tempered, the mechanical properties of the shell are more superior, and it has better strength and better elasticity;Welding materials.
- Q: Casting parts need to be subjected to the kind of heat treatment after the weldment is finished
- Annealing is needed to eliminate stress and refine grain
- Q: Is the cast steel a casting part?
- Yes, molten steel is poured into the mold and cooled to become a casting. Can also cast iron, cast aluminum, plastic casting.
- 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: What method of casting does not rust? I think the sample is like oil
- The surface of a general casting is easy to rust. In order to prolong the rusting period, antirust paint or antirust oil is usually sprayed. What you said should be anti rust oil.
- Q: the parts of the threaded hole is casting, casting the hole directly, and then tapping or casting, and then punch 10When the casting is ready, punch it again before tapping it Is the hole casting good or is it punched and tapped on the drilling machine after casting?
- There are several casesThe first hole with a diameter of less than 4MM is generally not done, or as a hole location only for a period of less than 10MM.Second for the big hole, some of the reasons for the holding force, we must increase the slope, direct tapping is unlikely, so it still needs post-processingThird for products with high tightness requirements, some cores need to be made even if they are very small, so they can be tapped directlyFourth, some due to technical requirements, regardless of the size of each other's requirements must be made, there is no wayThe above methods are common, and they will encounter many small problems in actual production.
- Q: I often see Waixiejiagong drawings, casting, how to distinguish the latheman.
- Casting rough drawings generally no processing symbols, processing drawings indispensable is processing symbols!
- Q: What's the density of the cast iron? The density is thin and the density is thin
- Generally cast iron thick place, density is empty, thin place density a little more.
