- Q:It is generally said that cast iron is re smelted by pig iron. My question is..:1 pig iron for melting iron, is directly cast into products (such as bed cover, etc.); or that is just the first pig iron smelting iron casting, such as to cover, bed and other products, will once again cast iron melt to casting?2, there are many castings to the engine. Are these castings made by the engine manufacturer themselves or bought by others?There is no need to answer all. Thank you！！！
- As a pig iron smelting, iron smelting belongs to physical, two belongs to the chemical refining, smelting, smelting generally not as a product after use, the product can be used as a chemical composition and casting the two refining, in general is to scrap as additional material after melting making products; engine castings have professional manufacturers making castings. You can own professional production of engine castings.
- Q:There is a little trace of polishingShock polishing is even worseElectrolysis can not be uneven, there is a slight bump
- Buffing should be better, to see how your embryo, but a bit difficult
- Q:For example, casting parts contain many holes, inclusions and other defects, the size and the number of holes exceed which limit is not qualified
- According to the grade of the parts, according to the relevant standards, the regular drawings will be noted in the technical requirements of the parts.
- 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:Can the casting part be phosphating with the phosphating solution of the pickling board?
- If it is Phosphating for painting, it is not necessary, because the surface of the casting is rough and can be firmly bonded with the paint film.
- Q:Younger brother is to do casting valve, precision casting parts, the valve internal sand serious, but the appearance is very standard, this is why, for God answers, thank you!
- Valve sand core mold drying is not in place, excessive water content
- 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: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?

- 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.
- Radial drilling machine can achieve boring, reaming function, but as much as you want, according to your requirements and material to determine!
- Q:Is 316 casting better than 304 casting?
- The degree of difficulty in the process of casting depends mainly on the structure, precision requirements, and hardness of the casting.
