FAQ

1. How about your price?

A: 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. 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 requirement, but it maybe let your purchasing cost changed also.

Q: How to improve the surface roughness of casting parts?: First, the accuracy of the model should be improved; two is to change the molding technique; the three is the coating; and the worker's technical level.

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: 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!: You oily sludge!Is not the general market on the soil?If it isPlease use two groups of chemicals to reinforce the soilOr suggest your company?Do the putty or paint film after doingThat's better

Q: Domestic large steel castings factory which is better, recommend!: At least spend money on research and development, then the quality should be all right.

Q: What are the casting parts tested?: The surface brightness, appearance, size, chemical composition, weight, material, surface defects, internal defects, seals need to be checked, leakage, etc.

Q: In theory, which is more expensive, forging parts or casting parts?: The structure of the casting is relatively flexible in design, and the modeling is easy to realize.

Q: the parts of the threaded hole is casting, casting the hole directly, and then tapping or casting, and then punch 10When the casting is ready, punch it again before tapping it Is the hole casting good or is it punched and tapped on the drilling machine after casting?: There are several casesThe first hole with a diameter of less than 4MM is generally not done, or as a hole location only for a period of less than 10MM.Second for the big hole, some of the reasons for the holding force, we must increase the slope, direct tapping is unlikely, so it still needs post-processingThird for products with high tightness requirements, some cores need to be made even if they are very small, so they can be tapped directlyFourth, some due to technical requirements, regardless of the size of each other's requirements must be made, there is no wayThe above methods are common, and they will encounter many small problems in actual production.

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: After reaming, the roughness can reach several levels, that is to say, the sample.Casting parts in rocker arm drilling, reaming, roughness, block. After reaming, the roughness can reach several levels, that is to say, the sample.: Not processed, do not understand your problem... There's something wrong with the drilling machine. Please call me
