Forged Grinding Ball 20mm to 150mm Size

Q: How to calculate the price of casting parts?: According to the complexity of the workpiece, material and casting requirements and process yield

Q: Why does the surface of stainless steel casting mirror mirror ripple?: Because the grinding machine is layer by layer. And the material inside the casting is not completely uniform.

Q: Why do cheap cars like stamping parts instead of casting parts?: The difference between automobile stamping parts and castingsAs the saying goes, there will be progress in comparison. In fact, through comparison, we can find the advantages and disadvantages of both. Next, we will talk about the difference between car stamping parts and castings.Looking for national casting orders, ductile iron castings, purchasing castings, foundry orders, and consulting foundry technology issuesCasting order networkAutomotive stamping parts are widely used in every field of our life, including some electronic components, auto parts, decorative materials and so on.

Q: In theory, which is more expensive, forging parts or casting parts?: The structure of the casting is relatively flexible in design, and the modeling is easy to realize.

Q: How to distinguish the forging parts and casting parts accurately: Distinguish from scopeShanghai Zhejiang forest auto parts experts pointed out that the forging process can eliminate cast loose, metal welding holes, so an important part of high load working conditions, severe machinery, in addition to relatively simple shapes can be rolled plates, profiles or welded parts, the forging process. Because of its low cost and good economy, casting parts processing is widely applied and belongs to the basic process of modern machine building industry.

Q: As shown, how do I achieve the tightness test of this product, and achieve industrial production? Seek expert advice.: Precise and tight sealing of the surface to which the test piece is to be tested, equipped with an airtight test instrument, and an electrical control system. You can complete automated testing equipment

Q: Why do casting parts have air holes?: First, from the source, tools, raw material drying, in the process of melting into the reaction gas, another influence is pouring process, such as high temperature solidification gas dissolved too much after not excluded. The method can adjust the pouring temperature properly, control the source of gas (drying and controlling the inoculant, especially the content of magnesium), and add cooling iron to change the solidification mode. It depends on what kind of casting you are. You can't make it clear at once. And molding sand relationship is mainly water content and permeability, brush coating resin content.

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: What foundry factories are used in the casting parts of China's major automobile manufacturers?: This is too muchYou do not have a specific list of statistics, but there are many foundries in china!Moreover, car prices are unlikely to be ordered in the local factories!

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
