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: The casting defects of pores, trachoma how to repair?: Metal repair can be used to fill the repair. Airhole 2mm following LT102 recommend the use of liquid metal repairing agent.

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: How to get rid of casting sand inside casting parts?: Are you saying that in the sand casting cavity? We use the manual blast, he is like a pipe will be automatic shot out of the grit, into the casting cavity, to remove the internal cavity in the purpose of casting sand!

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.

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?: There are several casesThe first hole with a diameter of less than 4MM is generally not done, or as a hole location only for a period of less than 10MM.Second for the big hole, some of the reasons for the holding force, we must increase the slope, direct tapping is unlikely, so it still needs post-processingThird for products with high tightness requirements, some cores need to be made even if they are very small, so they can be tapped directlyFourth, some due to technical requirements, regardless of the size of each other's requirements must be made, there is no wayThe above methods are common, and they will encounter many small problems in actual production.

Q: After reaming, the roughness can reach several levels, that is to say, the sample.Casting parts in rocker arm drilling, reaming, roughness, block. After reaming, the roughness can reach several levels, that is to say, the sample.: Not processed, do not understand your problem... There's something wrong with the drilling machine. Please call me

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 foundry factories are used in the casting parts of China's major automobile manufacturers?: For example Changchun FAW, under a casting, two casting and other casting plant, but there are more than half of all outsourcing in Tianjin Hebei Shandong purchase, many automobile enterprises to casting foundry.

Q: Heat treatment process and purpose of casting parts: Natural aging (also known as Chang Hua): lost in the open, the sun and rain, can have experienced years of wind and frost.
