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: What are the requirements for casting steel castings?: 1, high quality requirements of the surface or the main processing surface should be placed below.

Q: Domestic large steel castings factory which is better, recommend!: Do the casting manufacturer of large steel castings, Hunan Jinsha heavy industry science and technology limited company, heard that their professional only more than 1 tons of steel castings, anyway, 150T just big, the company won a lot of foundry industry patents should be good.

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 cause of fracture and why there is no toughness: This question is too broad, see what the casting casting Oh in order to reduce the wayward cast steel, ductile iron, gray iron and white iron, you can choose the material according to their own requirements.

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

Q: We are small castings, the need for surface treatment of shot blasting machine, about how much?: The choice of shot blasting machine, this is according to the workpiece size, yield, whether can collision, and the working time and other factors considered, while the price of different blasting machine are not the same, but the vast majority of small castings used crawler shot blasting machine, according to the comprehensive consideration of factors such as yield, size of workpiece commonly used on the market the crawler shot blasting machine has Q324, Q326, Q328, Q3210, and each time the amount of their treatment were 125KG, 200KG, 400KG, 600KG, the specific use of what types also need to be determined according to the actual situation

Q: What are the general technical requirements for casting parts?: No matter what kind of material casting, there are the following major requirements:Material requirements. Mainly hardness, tensile strength, elongation, impact toughness.Two, dimensional accuracy and shape accuracy. Different castings have different requirements. Different sizes and geometric tolerances and different tolerances are adopted.Three, according to the use requirements, the casting of other defects, acceptance requirements. Such as holes, sand holes, shrinkage, slag, sand, crack.........Four. Requirements for defect repair.

Q: Lathe processing stainless steel casting parts to use what type of tool, the speed into the amount of how much tool angle: It has something to do with the size of your work, and it has a lot to do with the blade you're using right now.

Q: Shandong foundry, casting small pieces of precision casting: Dongying Huayang precision casting factory, the smallest to do 2G pieces.
