Q:Tolerance standard for casting parts
Usually manual molding optional CT11 class, ordinary machine modeling optional CT10 class, high pressure molding should reach CT9 level. The tolerances on the wall thickness of the casting are comparable to those of other dimensions of the same casting.
Q:ZGMn13 casting parts processing, with what knife head good?
The ZGMn13 itself is not have processing, if only the processing point, sharpening, ordinary can, if the processing area is relatively large, ZGMn13 external impact load is bigger,
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:How can the casting be quenched and tempered?
Cast steel annealing or normalizing parts in strength and toughness is insufficient, can be used in quenching and tempering treatment. It is mainly used for gear, gear and other parts of the cast steel. The conditioning has two kinds: one kind is cast directly after quenching and tempering, with warm water (40---50 degrees) intermittent cooling, suitable for ZG270---500, ZG310----570 and other castings.
Q:Where is the difference in performance between the rolled and cast parts of the same part?
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:Shandong foundry, casting small pieces of precision casting
Dongying Huayang precision casting factory, the smallest to do 2G pieces.
Q:What kind of flaw detector is better for casting parts?
If you want to detect internal defects, you can use ultrasonic flaw detector, ray flaw detector can also, but the ray of the safety protection level is too high, not recommended priorityMacro Xu flaw detector answered, such as the magnetic particle inspection machine has the demand can contact us, Baidu "macro Xu flaw detection""
Q:What is the difference between the casting drawing and the car work drawing?
Casting rough drawings generally no processing symbols, processing drawings indispensable is processing symbols!
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!
Increase the refractoriness and looseness of core sand
Q:Casting pieces of plastic processing requirements can not fall off the skin,
The pre treatment temperature and the quality of plastic powder are likely to be problems
