- 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?
- Riga. Copper is copper components, promote the graphitization of the copper element, make dense tissue, and to refine and improve the uniform distribution of graphite, which can reduce the chilling tendency of the cast iron, but also can promote the formation of pearlite, has a favorable effect on the section sensitivity. Copper has the tendency to strengthen cast iron, ferrite and pearlite, so it can increase the strength of cast iron. The tensile strength and bending strength of cast iron almost increase with the amount of copper in it, especially in low carbon cast iron.
- 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: The casting sand is going on
- 3, prevention measures(1) to improve the strength of sand mold (core), especially surface strength, high temperature strength, refractoriness, compact, better coating, good core coating and parting surface coating.(2) mould and box can prevent damage;(3) the core should have clearance.
- 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?
- Aluminum alloy die-casting parts or casting box and other parts of the threaded hole, in the case of processing conditions, it is best to use wire tapping or machine tool processing! Direct casting is not advocated.
- Q: What is the reason for 304 stainless steel precision casting parts to be changed?
- 304 stainless steel is easier to change than ordinary steel. Because the 304 heat conductivity is lower than that of the low doped steel, the temperature is even more uneven, and 20% of the non ferrous elements also make the distribution of internal and external elements more uneven, hard and soft inside. Each of these two produces greater internal stresses, resulting in a variant.
- Q: The difference between cement sand castings, resin sand castings and vacuum casting parts
- The clay wet sand castings casting weight from a few kilograms until tens of kilograms, but the clay dry type of casting production can be weighed dozens of tons.For medium and large castings, cast iron, cast steel can be self hardening sand with resin can be water glass sand production, can obtain the precise size, smooth surface castings, but casting precision, surface roughness, density and microstructure, mechanical properties and material cost of sand casting production is often poor, so when the higher performance requirements of castings, should adopt other casting methods, such as casting (lost wax casting), die casting, low pressure casting.
- Q: How to distinguish the forging parts and casting parts accurately
- To distinguish from the use of materialsForging materials are mainly made of carbon steel and alloy steel of various components, followed by aluminum, magnesium, titanium, copper and their alloys. The original state of the material is rod, ingot, metal powder and liquid metal. The materials needed for casting are mostly metal, wood, fuel, molding materials and so on. In contrast, the forging parts rarely produce dust, harmful gas and noise, etc., and play a more obvious role in environmental protection. Of course, because of this, the price of forged parts on the market is higher than that of castings.
- 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?
- 3, the resonance method is cast on its resonant frequency vibration 1060ndn, to eliminate the residual stress in casting.
- Q: The difference between sheet metal and casting parts
- Sheet metal refers to the metal sheet (which can be bent straight board, etc.) generally uniform thickness, can obtain the required parts by stamping, molding, welding, splicing and other processing methods.
