FAQ

1. How about your price?

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

2. What is your minimum order requirement?

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:How to calculate the price of casting parts?: According to the complexity of the workpiece, material and casting requirements and process yield

Q:Casting parts have poor surface finish. What sand is used to make them?: Now resin sand, coated sand and other processes are also very good surface.

Q:What are the effects of stiffeners on castings, or on welded parts (for 2 tons or less), casting or weldments on stiffeners?: Please consider the following points:1, batch: if the product batch is very large, casting will certainly have advantages, cost sharing will be very low. If less, it is recommended to use weldments.2. Reinforcement structure: if the structure is relatively simple, it is recommended to use welded parts, complex, preferably casting.

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: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:When the blank is a casting, the margin is evenly distributed, how should rough machining?Please help friends from mechanical classes.There is another problem: in the NC milling plane contour machining, when the rough margin is large, how to deal with.Who can help in time, add 20 reward. Urgently!!: Problem one,1, according to drawings, castings, material requirements and machine power, choose the right diameter of roughing tools, and can process this material blade type.2, according to the actual size of the casting blank, calculate the number and path of the knife, pay attention to small cutting depth, large feed, cutting width, to ensure that the tool diameter 80 - 90%, the amount of not full knife cutting, this tool and machine tool damage.Question two,If they can not change the casting blank allowance under the condition that the quantity large diameter cutter, such as milling cutter main angle 7560 degrees can give reasonable processing parameters, the same cutting depth should not be too large, because in the same machine power, tool diameter increases, cutting depth will need smaller.

Q:How to distinguish the forging parts and casting parts accurately: Distinguish from scopeShanghai Zhejiang forest auto parts experts pointed out that the forging process can eliminate cast loose, metal welding holes, so an important part of high load working conditions, severe machinery, in addition to relatively simple shapes can be rolled plates, profiles or welded parts, the forging process. Because of its low cost and good economy, casting parts processing is widely applied and belongs to the basic process of modern machine building industry.

Q:What foundry factories are used in the casting parts of China's major automobile manufacturers?: Tangshan Yongding automobile spare parts factory also give a lot of supply, casting factory of Tangshan n to the car enterprises casting wheel gearbox etc.The team of casting experts welcome you to ask questions and accept questions!

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?: Usually manual molding optional CT11 class, ordinary machine modeling optional CT10 class, high pressure molding should reach CT9 level. The tolerances on the wall thickness of the casting are comparable to those of other dimensions of the same casting.
