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 get free samples?

A: Yes, we can provide the free samples, but you need to bear delivery freight.

3. 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: Why does the precision casting factory not usually make iron castings?: The so-called precision parts is the size, roughness requirements of the piece. Cast iron parts generally do not reach the accuracy.

Q: Why do cheap cars like stamping parts instead of casting parts?: The difference between automobile stamping parts and castingsAs the saying goes, there will be progress in comparison. In fact, through comparison, we can find the advantages and disadvantages of both. Next, we will talk about the difference between car stamping parts and castings.Looking for national casting orders, ductile iron castings, purchasing castings, foundry orders, and consulting foundry technology issuesCasting order networkAutomotive stamping parts are widely used in every field of our life, including some electronic components, auto parts, decorative materials and so on.

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: Casting parts have poor surface finish. What sand is used to make them?: V casting, EPC, precision casting of the surface is good.

Q: What is the casting material?: The casting material is usually made of gray cast iron, nodular cast iron and vermicular graphite cast iron

Q: As shown, how do I achieve the tightness test of this product, and achieve industrial production? Seek expert advice.: Precise and tight sealing of the surface to which the test piece is to be tested, equipped with an airtight test instrument, and an electrical control system. You can complete automated testing equipment

Q: Which surface is coarser for cast iron or cast steel castings? Why?: The surface of the steel is more rough, because the coating sand cast steel cast iron particles compared with graphite coating degree, the other one is to get a better air permeability and collapsibility of sand, the compaction degree is smaller than iron. Roughness mainly depends on the surface roughness on the surface of the sand.

Q: My parts complex, machining costs are relatively high, so want to cast, but the surface needs anodizing, what material will be better?: Yes, the cast aluminium is polarized and gray, but the key problem is to guarantee the quality of the aluminium casting, and the quality of the other aluminium casting is not good.

Q: Lathe processing stainless steel casting parts to use what type of tool, the speed into the amount of how much tool angle: What kind of work, what kind of material, 204201304316, how big live ah? You ask?Can the 201 pieces of material and 304 of the pieces fit in a single car? Can I use the universal YG8 knife? Straight, knife, pipe thread?You should live to say, understand, say, do not understand, draw a simple drawing with Baidu doodle, marking the important size, this is good to answer ah!
