Q:Why does the precision casting factory not usually make iron castings?
The so-called precision parts is the size, roughness requirements of the piece. Cast iron parts generally do not reach the accuracy.
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:What's the density of casting?
There is a hot knot in the thick area, which easily causes microscopic shrinkage and makes the casting not dense. A riser may be added for shrinkage relief.
Q:What's the cause of the choking of the casting?,
Causes of choking fire:1., casting material in the pouring of gas;
Q:Stainless steel mirror polishing precision casting parts is very difficult, 20
Use the vibrator to polish the material: the high aluminum porcelain 4cm (with a polishing agent that has an automatic mending function), you go find this polish,
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: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:What is the ejection angle of the die casting (Tan Gang)?
Especially deep hole, and customers to discuss, generally take 0.3-1 degrees is enough
Q:Casting pieces of plastic processing requirements can not fall off the skin,
Cast iron has not been done, if it is iron, then in the spray before going through strict pretreatment, the surface can not have a little oil dust
Q:How to solve casting defect casting?
Different defects, different solutions, some shortcomings, the current domestic level can not be resolved
