Q:How can the casting be free of trachoma?
3, the gate is not facing sand core, flush sand core, will cause trachoma.
Q:Which surface is coarser for cast iron or cast steel castings? Why?
The surface of the steel is more rough, because the coating sand cast steel cast iron particles compared with graphite coating degree, the other one is to get a better air permeability and collapsibility of sand, the compaction degree is smaller than iron. Roughness mainly depends on the surface roughness on the surface of the sand.
Q:Casting parts have poor surface finish. What sand is used to make them?
Manual coal dust, clay sand is a little worse. Mechanical styling is not bad either.
Q:We are small castings, the need for surface treatment of shot blasting machine, about how much?
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 causes of pitting on the surface of a precision casting?
The quality of the shell surface is out of order. Or shot blasting out of question.
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:Why does the surface of stainless steel casting mirror mirror ripple?
Those should be head prints. If required, it would be better to throw with a single grinding head.
Q:How do you mark it on the drawing? Do you need to discuss it with the manufacturer?Because the casting allowance is the standard, then, after all, is the theoretical value, the actual level depends on the manufacturer, so is it necessary to ask the manufacturer?
The general foundry casting technology division will mark put shrinkage and the allowance of the map in your chart (usually with the red pen) for the production of wood or other material wood workers die drawings.
Q:When there is no flaw detection for large casting parts, is there any crack inside?
According to the industry standards, within the scope of the standard requirements to determine whether the product is qualified
Q:the parts of the threaded hole is casting, casting the hole directly, and then tapping or casting, and then punch 10When the casting is ready, punch it again before tapping it Is the hole casting good or is it punched and tapped on the drilling machine after casting?
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
