Q:Is the cast steel a casting part?

Cast steel is divided according to material, as well as cast iron parts, cast aluminum parts and so onCasting parts are divided according to the method, as well as forging partsCast steel parts must be casting parts

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:How to cast iron and wrought iron collocation

3, if you have a file in the hand, can be used to file to see finish can also make a judgment from the file down the iron can also be seen, but this is beyond your request, it can be done in the factory. 4, if placed in the grinder grinding, see iron spark from a judge or iron wrought iron, but this is only to do in the factory. About it, may not be full, but through these methods, generally can distinguish between iron or wrought iron.

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:In theory, which is more expensive, forging parts or casting parts?

It depends on the structure. In theory, the shape of the forging is relatively simple, but the requirement of internal structure is relatively high

Q:We are small castings, the need for surface treatment of shot blasting machine, about how much?

according to the comprehensive consideration of factors such as yield, size of workpiece commonly used on the market the crawler shot blasting machine has Q324, Q326, Q328, Q3210, and each time the amount of their treatment were 125KG, 200KG, 400KG, 600KG, the specific use of what types also need to be determined according to the actual situation

Q:What's the effect of casting copper?

Copper is one of the main corrosion resistant alloys. When the mass fraction of copper in cast iron is from 0.25% to 1%, the corrosion resistance of copper in the industrial atmosphere can be obviously increased. But copper has very little corrosion resistance in lye or salt solution.Copper can increase the flowability of molten iron and improve its casting ability remarkably.Copper can increase the coercive force and residual magnetic force, but the permeability is not affected.Combined use of copper with other alloy elements, such as copper chromium, copper chromium molybdenum, copper molybdenum, copper manganese, copper vanadium, can achieve greater results.

Q:Heat treatment process and purpose of casting parts

Methods: artificial aging or natural aging (also called normalization) treatment.Artificial aging: heating to 2-3 Baidu, it is best to apply mechanical vibration, and maintain a period of time.

Q:What foundry factories are used in the casting parts of China's major automobile manufacturers?

For example Changchun FAW, under a casting, two casting and other casting plant, but there are more than half of all outsourcing in Tianjin Hebei Shandong purchase, many automobile enterprises to casting foundry.

Q:Which master knows how the casting tolerances for malleable iron, gray iron and ductile iron should be chosen? Hurry up, thank youCan you provide a tolerance scale for castings, please?

The tolerance of a specific size can be obtained from the tolerance grade and nominal size of the casting.
