FAQ

1. How about your price?

A: As one of famous manufacturers of Ductile iron products in China, Our prices are very favorable and competitive. The customers from all-over the world.

2. What is your minimum order requirement?
A: We will indicate the MOQ for each item in the quotation sheet. we accept the sample and trial order. If the quantity of single item can't reach the MOQ, the price should be sample price.

Q:Why do casting parts have air holes?: Cangshan Qiao hidden his answer is quite comprehensive, you can try using inert gas to reduce air cover

Q:Does anyone know how to make precise casting parts for aerospace or manufacturers of single and small quantities of automotive parts and components, mainly in Beijing, Tianjin and Tangshan?: List of China's military enterprises list of ten major military groupsChina Nuclear Industry Construction Group CorporationChina Aerospace Science and Technology CorporationChina Aerospace Science and Engineering CorporationChina Aviation Industry CorporationChina Aviation Industry Corporation IiChina State Shipbuilding CorporationcsicChina North Industries Group CorporationChina South Industries Group CorporationChina National Nuclear CorporationKey military enterprisesShipbuilding industry:China State Shipbuilding Corporation (South ship group), (China Shipping Group)China Shipbuilding Industry Corp (North Ship group), (China Shipbuilding Industry)Guangzhou Shipyard International Limited by Share Ltd (GSI)Jiangnan Heavy Industry Limited by Share Ltd (Jiangnan Heavy Industry)Nuclear industry:China National Nuclear Corporation (CNNC)China Nuclear Industry Construction Group Corporation

Q:How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness: Hot galvanizing doesn't seem to workThe zinc layer is 275g/ square meters of material coating is 0.019mm (mm), up to 0.08 thick.

Q:What's the density of the cast iron? The density is thin and the density is thin: Uneven casting density is caused by uneven shrinkage of the casting during solidification.

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:Lathe processing stainless steel casting parts to use what type of tool, the speed into the amount of how much tool angle: There is YW1 best, if not using YG6X, YG8 is ok!The speed should not be high, the greater the diameter, the lower the speed! For example, a diameter of 100 mm, speed is not greater than 80 rpm, each point is good!The main tool is the front angle to be larger, more than 6 degrees, and the groove should be wider and larger to reduce the cutting resistance! When the rear angle is properly reduced and the strength is increased, it is recommended to take 3 degrees.The main components are: spindle box, exchange gear box, feed box, slide box, tool post, tail frame, light bar, lead screw, bed, foot and cooling device.Spindle box: also known as the headstock, it is the main task of the rotary motion of the main motor came through the transmission mechanism of a series of positive and negative spindle to be required two different steering speed, the spindle box gives impetus to the movement of the box. Medium spindle is the key part of lathe. The stability of the spindle on the bearing directly affects the quality of the workpiece. Once the rotation accuracy of the main shaft is reduced, the value of the machine tool will be lowered.

Q:How is the silicon sol precision casting part priced? What is the price per ton of casting? Such as 304 material.: I am doing this for sale, if the price is mainly based on the product structure, the difficulty of pricing. At present, if it is more formal and material guarantee manufacturers generally in 48-53 yuan /Kg (of course, products have a certain weight, such as greater than 100g), our company's current price of about 53 yuan /Kg or so. .

Q:How can the casting be quenched and tempered?: Another is the result of pre heat treatment (quenching or annealing) after quenching and tempering treatment, suitable for ZG35SiMNMo, ZG35CrMo and so on. Please tell the casting process is your product and material and then set tempered.: shutup:

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:When there is no flaw detection for large casting parts, is there any crack inside?: According to the industry standards, within the scope of the standard requirements to determine whether the product is qualified
