- Q:Why do casting parts have air holes?
- There are many reasons for casting porosity, mainly due to:1. smelting process is unreasonable, metal liquid absorbs more gas;2. the gas in the mold invades the metal liquid;3. from the mold is more water brush, core dry;4. the casting has poor ventilation;5. ladle tools are not dry.Wait。
- 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: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 casting material?
- Gray iron, carbon steel, low alloy steel, ductile iron, stainless steel, Aluminum Alloy can all be cast out
- 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!
- Valve sand core mold drying is not in place, excessive water content
- Q:What are the effects of stiffeners on castings, or on welded parts (for 2 tons or less), casting or weldments on stiffeners?
- Please consider the following points:1, batch: if the product batch is very large, casting will certainly have advantages, cost sharing will be very low. If less, it is recommended to use weldments.2. Reinforcement structure: if the structure is relatively simple, it is recommended to use welded parts, complex, preferably casting.
- 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's the effect of casting copper?
- Riga. Copper is copper components, promote the graphitization of the copper element, make dense tissue, and to refine and improve the uniform distribution of graphite, which can reduce the chilling tendency of the cast iron, but also can promote the formation of pearlite, has a favorable effect on the section sensitivity. Copper has the tendency to strengthen cast iron, ferrite and pearlite, so it can increase the strength of cast iron. The tensile strength and bending strength of cast iron almost increase with the amount of copper in it, especially in low carbon cast iron.
- Q:Casting blank in the cooling process to release a large amount of heat energy, what can be recycled?
- Casting, do not need to provide a rough casting foundry drawings, according to your chart will put foot margin in the processing needs of the surface, the rest of the size can be found according to the mechanical design manual and manual casting. General Casting Factory Casting Division will be in your chart marked on shrinkage and processing margin figure (usually with red and green pen) to the patternmaker production of wood or other material mould diagram.
- 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.
