Q: How to improve the surface roughness of casting parts?
One is to improve the accuracy of the model; the two is to improve the molding sand mesh. How much is the other relationship?.
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: What are the effects of stiffeners on castings, or on welded parts (for 2 tons or less), casting or weldments on stiffeners?
3, weight: if reinforcement in products, casting weight is generally greater than the welding parts (the internal organizational structure and mode of production determines the mechanical properties of materials, so it determines the weight of the product), considering the cost of transportation, certain priority structure.
Q: The casting sand is going on
Dispersed sand inclusion is common on the surface and subcutaneous of steel castings, often concentrated on the outer surface of the upper box and the inner surface of the lower case, and a few of them are inside the cast steel parts.
Q: What method of casting does not rust? I think the sample is like oil
The surface of a general casting is easy to rust. In order to prolong the rusting period, antirust paint or antirust oil is usually sprayed. What you said should be anti rust oil.
Q: For example, casting parts contain many holes, inclusions and other defects, the size and the number of holes exceed which limit is not qualified
According to different casting process and parts materials, each has relevant standards, can be found online;
Q: What are the causes of pitting on the surface of a precision casting?
There is a bump on the mold. Or casting cooling fast.
Q: Which master knows how the casting tolerances for malleable iron, gray iron and ductile iron should be chosen? Hurry up, thank youCan you provide a tolerance scale for castings, please?
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: What reason is the bronze statue choking fire?
The casting process in boiling phenomenon, is the setting of the exhaust hole positioner position or number is not reasonable, the air cavity can not be discharged, overwhelmed by a material inlet, reflux, change mould, sincerely help you look forward to adopt,
Q: How can the casting be free of trachoma?
3, the gate is not facing sand core, flush sand core, will cause trachoma.
