- Q: How to calculate the price of casting parts?
- According to the complexity of the workpiece, material and casting requirements and process yield
- Q: What are the factors affecting the machining process of the casting material and structure?
- The impact on the machining is obvious, it should be the material and heat treatment of the castingCarbon steel parts should be treated by heat treatment (annealing) without special conditions. It can effectively prevent the uneven hardness and hard points. It is easy to turn.
- 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 is the difference between forging parts and casting parts?
- The casting parts are low in cost and short in production period. Because the molten iron has good flow properties, complex shapes can be formed. But because there may be sand holes, pores, shrinkage holes and other defects, the quality is unstable, easy to produce many defects, mechanical properties are not forged well, thus affecting the service life.
- 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
- For example, the castings shall be in accordance with the requirements of the second types of castings in the technical requirements for aluminum alloy castings of GB/T9438-1999;
- Q: Why do casting parts have air holes?
- Cangshan Qiao hidden his answer is quite comprehensive, you can try using inert gas to reduce air cover
- Q: What kind of flaw detector is better for casting parts?
- If the casting is very small, can be used for fixed magnetic detection machines, of course with fixed magnetic powder the testing machine, the best first contact the manufacturers, because the fixed magnetic particle testing machine belongs to the non-standard equipment, according to the workpiece size, different shape, manufacturing daily inspection and measurement.
- Q: When there is no flaw detection for large casting parts, is there any crack inside?
- Cracks are considered serious levels of defects and should be repaired
- 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!
- If is casting, internal shell mold may be not completely dry, strength is not enough, resulting in shell mold collapse into molten steel.It is also possible that the refractory is not refractory enough.
- Q: Is 316 casting better than 304 casting?
- It is comprehensive. There is no simple comparison of the material to determine the degree of difficulty in processing
