Q:We are small castings, the need for surface treatment of shot blasting machine, about how much?: The choice of shot blasting machine, this is according to the workpiece size, yield, whether can collision, and the working time and other factors considered, while the price of different blasting machine are not the same, but the vast majority of small castings used crawler shot blasting machine,

Q:How to cast iron and wrought iron collocation: So we can only watch and ear distinction: 1, see: Iron fracture is rough, showing a bead (for the sake of coarse grain iron), and wrought iron fracture is generally more smooth; if this is a new fracture, but also to see the dark and shiny born iron wrought iron pig iron is bright; the fracture is generally irregular, because it is very brittle, mostly is interrupted, (which is processed, it is very flat and wrought iron) must not be interrupted, mostly by certain way processed separately, so the fracture is generally neat; if the fracture is that is cutting, wrought iron, iron is not cutting; iron surface will not have pores, familiar iron porosity; if a piece of iron is a significant deformation (bending) that is wrought iron because of poor plasticity It doesn't have to be so deformed, it's really bent, or it's broken, or it's obviously cracked, and it doesn't bend very much. There are some details that can not be made clear. It is necessary to have some experience.

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:How much is the amount of electrophoretic paint per square meter used in the casting?: It was a very simple question, and it was complicated by what you said.

Q:How can the casting be quenched and tempered?: Another is the result of pre heat treatment (quenching or annealing) after quenching and tempering treatment, suitable for ZG35SiMNMo, ZG35CrMo and so on. Please tell the casting process is your product and material and then set tempered.: shutup:

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?: Aluminum alloy die-casting parts or casting box and other parts of the threaded hole, in the case of processing conditions, it is best to use wire tapping or machine tool processing! Direct casting is not advocated.

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: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.: The finish of reaming depends on the material and the sharpness of the reamer, as well as the speed and speed of the top and bottom. Marine machine tool

Q:How to solve casting defect casting?: Prevention methodReduce the gas in the metal liquid and oxidize the slag, improve the fluidity of the metal liquidIncrease pouring temperature and pouring speed, strengthen slag collection, slag block or bottom pouring bag, teapot ladle pouring, can not cut off when pouring, prevent the slag from blocking the nozzle, and cause the casting to breakIncrease the sprue and sprue height, increase the runner section area and the sprue number, and improve the filling speed and the metal hydrostatic headImprove the casting design and increase the thickness of the thin-wall part of the castingChange the pouring position and pouring system, the casting thin wall plane is located at the top and away from the gate, to prevent the filling of liquid metal splashing, eddy current, avoid metal stream in the casting thin sections or core support, cold iron, insert the confluence, when necessary, take horizontal vertical pouring cold or inclined castingIncrease the permeability of core and sand, strengthen the exhaust of mould, and the quantity of air outlet and riser should be enoughChange the size and location of the core, the inner cold iron, the core support, the internal cold iron, the insert should be no rust, no oil pollutionCheck the type, tight box, press the operation of iron is safe, to prevent running fire

Q:Is the cast steel a casting part?: Cast steel is divided according to material, as well as cast iron parts, cast aluminum parts and so onCasting parts are divided according to the method, as well as forging partsCast steel parts must be casting parts
