2.Can I request to change the form of packaging and transportation?

A:Yes,We can change the form of the packaging and transportation according to your request, but you have to bear their own costs incurred during this period and the spreads.

Q:We are small castings, the need for surface treatment of shot blasting machine, about how much?: The choice of shot blasting machine, this is according to the workpiece size, yield, whether can collision, and the working time and other factors considered, while the price of different blasting machine are not the same, but the vast majority of small castings used crawler shot blasting machine, 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:How to distinguish the forging parts and casting parts accurately: Distinguishing between forging and casting can be done from the following points:From the principle of distinguishingForging processing of machining by hammer or press and other equipment for forging parts produced in hot state, casting processing of metals into liquid, pouring into the cavity with a specific shape, produced by machining parts after cooling solidification. Simply say that forging is the metal soft pinch molding, and casting the metal into thin cooling solidification.

Q:Can the casting part be phosphating with the phosphating solution of the pickling board?: Like stainless steel casting, duplex stainless steel casting is phosphating, ductile iron gray iron is not required

Q:I often see Waixiejiagong drawings, casting, how to distinguish the latheman.: The technical condition or the material column in the title column will tell whether it is a casting drawing or not. However, the need for casting drawings, and some also through machining (car, milling, etc.), this should be part of the process drawings, process drawings are described

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

Q:ZGMn13 casting parts processing, with what knife head good?: its surface wear resistance is high; the two is with the gradual wear of surface hardening, the hardening layer is continuously formed new if you have suggestions, processing, plasma cutting or flame cutting try

Q:How do you mark it on the drawing? Do you need to discuss it with the manufacturer?Because the casting allowance is the standard, then, after all, is the theoretical value, the actual level depends on the manufacturer, so is it necessary to ask the manufacturer?: The general foundry casting technology division will mark put shrinkage and the allowance of the map in your chart (usually with the red pen) for the production of wood or other material wood workers die drawings.

Q:Why do casting parts have air holes?: There are many reasons for casting porosity, mainly due to:1. smelting process is unreasonable, metal liquid absorbs more gas;2. the gas in the mold invades the metal liquid;3. from the mold is more water brush, core dry;4. the casting has poor ventilation;5. ladle tools are not dry.Wait。

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:Why does the surface of stainless steel casting mirror mirror ripple?: The surface can be improved by a little more than Xiasha
