Q:Casting parts by shot blasting, spray painting, baking after the formation of very small rust spots, how to solve ah?: The first process is very important. Shot blasting must be thorough. The solution is to wipe the surface of the paint with a release. Re shot

Q:What is the reason for 304 stainless steel precision casting parts to be changed?: Mainly because of the cooling shrinkage caused by internal stress caused. There is the change of temperature distribution in materials element imbalance, is typical of surface and internal, thin wall and thick wall, bottom and top.

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:Shandong foundry, casting small pieces of precision casting: Small foundry in Shandong too much, like many of us in Qingdao, then Dongying Changshun investment casting is a home, they are also casting precision casting equipment, specifically what I recommend that local enterprises, far is not convenient,

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?: The tolerance of a specific size can be obtained from the tolerance grade and nominal size of the casting.

Q:What is the casting material?: Commonly used gray cast iron, malleable cast iron, ductile iron, cast steel, etc., non-ferrous metal casting copper alloy, casting aluminum alloy, casting zinc alloy, 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?: You need to confirm what you use tap processing, so as to determine the size of the casting hole

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:What is normalizing, annealing, tempering, quenching? What is the difference between forging parts and casting parts?: According to the requirements of the workpiece annealing, there are many kinds of annealing process specifications, such as full annealing, spheroidizing annealing and stress relieving annealing. Steel the steel quenching is heated to the critical temperature Ac3 (hyposteel) or Ac1 (hypereutectoid steel) above a certain temperature, holding time, so that all or part of 1 Austenitic, then the cooling rate is greater than the critical cooling rate of fast cooling to below Ms (or near Ms isothermal) of martensite the body (or bainite transformation) heat treatment process. Aluminum alloys, copper alloys, titanium alloys, tempered glass and other materials are usually treated by solid solution or heat treatment with rapid cooling process. Tempering is a heat treatment process where the workpiece is hardened and heated to a temperature below AC1, which remains cool for a certain period of time and then cools to room temperature. Tempering generally followed by quenching, the purpose is: (a) to eliminate the residual stress caused by quenching, prevent deformation and cracking; (b) hardness, strength, plasticity and toughness of workpiece is adjusted, to use performance requirements; (c) the size of organization and stability, ensure the accuracy improvement; (D) and to improve the processing performance. Tempering is therefore the last important step in obtaining the desired properties of the workpiece. According to the tempering temperature range, tempering can be divided into low temperature tempering, medium temperature tempering and high temperature tempering. This answer is recommended by the questioner

Q:How to solve casting defect casting?: Different defects, different solutions, some shortcomings, the current domestic level can not be resolved
