Round Ductile/ Cast Iron D400 Manhole Cover with Frame (DN600)



Q:How do casting parts remove stress?
Annealing treatment, according to different casting annealing treatment, eliminate thermal stress, if need to restore hardness or increase hardness, and then quenching treatment
Q:Is the cast steel a casting part?
Yes, molten steel is poured into the mold and cooled to become a casting. Can also cast iron, cast aluminum, plastic casting.
Q:What is the ejection angle of the die casting (Tan Gang)?
Because after the wax, wax parts will have a slight contraction, which is good for demoulding. Many moulds don't do the ejection angle
Q:What are the factors affecting the machining process of the casting material and structure?
As for the metallographic structure, usually the finished products after casting are treated by heat treatment. The mechanical properties of the carbon steel after heat treatment (quenching and tempering) are detected. The stainless steels are treated by heat treatment (solid solution, etc.) and the metallographic structure is analyzedThere is a lot of talk and a bit of confusionIf you have a specific brand, you can search for Baidu or buy tools
Q:What method of casting does not rust? I think the sample is like oil
Close to the solder, and slowly dissolve is hot melt double-sided adhesive, otherwise it is oily double-sided adhesive.
Q:Domestic large steel castings factory which is better, recommend!
At least spend money on research and development, then the quality should be all right.
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 is the reason for 304 stainless steel precision casting parts to be changed?
Steel deformation control is one of the most common problems in the metal processing industry. Any process will occur. The casting is the largest deformation and the least fine. It is generally used to produce blank blanks
Q:When the blank is a casting, the margin is evenly distributed, how should rough machining?Please help friends from mechanical classes.There is another problem: in the NC milling plane contour machining, when the rough margin is large, how to deal with.Who can help in time, add 20 reward. Urgently!!
Personal advice:Because of the large margin, your outline is easy to guarantee;So the key is to consider the assembly and aesthetics of the casting. You have to find the machining criteria;Rough the datum so that it can be machined;After the outline, turn back to the finishing line.If the casting requirement is not high, the benchmark can be directly processed; (not recommended)Over
Q:Selection of hydraulic press is the casting parts and steel plate welding, how to choose?
Casting parts in one shape, the overall processing in this regard than steel plate welding better. The same price is much more expensive than steel. Large hydraulic presses seldom have casting parts.
