Q: How to calculate the price of casting parts?: Cost of raw materials + electricity (fuel) costs + workers' wages + managers' wages + transport costs + raw materials burned + accessories costs + equipment maintenance depreciation costs + management fees + tax. The most convenient, the raw material market price plus 2000 yuan, plus you want profits on the line.

Q: What are the factors affecting the machining process of the casting material and structure?: Medium carbon steel begins, and the casting can not be punched and tapped directlyStainless steel, ordinary grade (Fe based alloy element content, less) can not do heat treatment. But processing small holes or tapping to heat treatment (solution. In practice, the annealing treatment can also be). There are a lot of stainless steel matrix is not to say, for example, nickel, cobalt and tungsten. And so on.

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!: Cast iron has not been done, if it is iron, then in the spray before going through strict pretreatment, the surface can not have a little oil dust

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 to get rid of casting sand inside casting parts?: Are you saying that in the sand casting cavity? We use the manual blast, he is like a pipe will be automatic shot out of the grit, into the casting cavity, to remove the internal cavity in the purpose of casting sand!

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: How much is the amount of electrophoretic paint per square meter used in the casting?: In general, when the final thickness of 15-20 microns, cathode electrophoresis paint can be coated per kilogram of 6-8 square meters, the current general cathode electrophoresis paint for the price of 22 yuan / kg, so the cathodic electrophoresis electrophoresis paint cost at 4 yuan / square meters.

Q: What is the casting material?: Commonly used gray cast iron, malleable cast iron, ductile iron, cast steel, etc., non-ferrous metal casting copper alloy, casting aluminum alloy, casting zinc alloy, etc..

Q: Which surface is coarser for cast iron or cast steel castings? Why?: Roughness mainly depends on the surface roughness on the surface of the sand.

Q: Younger brother is to do casting valve, precision casting parts, the valve internal sand serious, but the appearance is very standard, this is why, for God answers, thank you!: Increase the refractoriness and looseness of core sand
