Q:General aluminum alloy die casting or casting box and other parts,
Single for this problem, the direct casting out of course good. But many times because of the limitations of the process, so we choose the post-processing hole
Q:How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness
Hot galvanizing doesn't seem to workThe zinc layer is 275g/ square meters of material coating is 0.019mm (mm), up to 0.08 thick.
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. At least spend money on research and development, then the quality should be all right.
Q:In theory, which is more expensive, forging parts or casting parts?
Compared with the price, the product with the same simple structure eliminates the material factorsThe forgings must be more expensive
Q:What are the design considerations for casting parts?
A: in the design of metal castings in a complex shape, if the production process is very difficult, should not affect the casting conditions, try to make the casting has simple shape, strong structure change, removed from metallic die for.
Q:How can the casting be quenched and tempered?
Another is the result of pre heat treatment (quenching or annealing) after quenching and tempering treatment, suitable for ZG35SiMNMo, ZG35CrMo and so on. Please tell the casting process is your product and material and then set tempered.: shutup:
Q:How about casting parts for a year?
2, heat aging (artificial aging), also known as stress annealing, is to heat the casting to 550-650 degrees, insulation 2 - 4h, with the furnace cooling to 150 - 200T, and then baked.
Q:What is the difference between the casting drawing and the car work drawing?
What you say is the difference between rough drawing and processing drawingThere must be a difference between the rough drawings and the rough ones
Q:What is the casting material?
Gray iron, carbon steel, low alloy steel, ductile iron, stainless steel, Aluminum Alloy can all be cast out
Q:Heat treatment process and purpose of casting parts
Objective: to stabilize tissues, eliminate or substantially reduce internal stress.
