FAQ

1.Q: Are you factory ?

YES! We are a professional ductile iron & grey iron casting Factory inChina.

2.Q: How long can you make your quotation:

Within 3 workdays after received your detailed product information

3.Q: Do you provide OEM Service?

Yes, we provide OEM Service.

4.Q: What 's your quotation element?

Drawing, material, weight and quantity.

Q: What is the ejection angle of the die casting (Tan Gang)?: Especially deep hole, and customers to discuss, generally take 0.3-1 degrees is enough

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: 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?: If it is not directly cast hole hole, later processing, large pores may be directly cast out,

Q: I often see Waixiejiagong drawings, casting, how to distinguish the latheman.: Yes, casting drawings are casting drawings with machining allowances, slopes, and gating systems

Q: The difference between cement sand castings, resin sand castings and vacuum casting parts: Vacuum casting is the process of using ventilation molds. Molten metal flows into the mold by air pressure, and then removes air to form a vacuum. The casting process is mainly used for small parts or jewelry with exquisite detailsCompared with the traditional clay sand casting, heat hardening resin sand casting production with low surface roughness, high precision, good quality characteristics, dimensional accuracy of resin sand mold after hardening with good rigidity and high, and not easy to deform, so in the choice of process parameters, mechanical processing you can select a smaller margin, thereby reducing the consumption of metal solution and machining cost, which can improve the dimensional accuracy of castings.

Q: Question, such as title, I hope I don't copy the definition of rolling and casting in Baidu encyclopedia, thank you: Service performance: heat conductivity, friction reduction, shock absorption, heat resistance and corrosion resistanceTo compare these properties, it depends on the specific material, structure, and use of the parts. Otherwise, there is no comparisonS

Q: What are the causes of pitting on the surface of a precision casting?: The quality of the shell surface is out of order. Or shot blasting out of question.

Q: Cause of choking of casting parts: Is it boiling from the picture? Does it sound like a fire? If not, it's not choking. I feel like choking. The gas doesn't drain out
