Sometimes if meet the size we don’t have, the new mould with your size and design can be considered from us. Let's talk more details about the New Mould and Charges. Then start our Cooperation.
- Q: Explain the heat treatment effect of casting parts, forging parts and welding parts
- 2 improve the crystal structure, enhance the formation and stability of spherical carbon crystal;Forgings are generally stress bearing members, and most of them are made of high strength medium carbon steel (alloy), which is formed by forging and fine crystalline. After the shell is annealed or quenched and tempered, the mechanical properties of the shell are more superior, and it has better strength and better elasticity;Welding materials.
- 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 difference between forging parts and casting parts?
- No, it's called die castingDifference: the die casting parts are simple in structure and large in batch sizeCasting: the use of a wide range of structures without restrictions
- Q: What are the casting parts processing engineering?
- At present, casting processing, according to metal classification, divided into cast iron, cast steel, casting non-ferrous metal.
- Q: What is the casting material?
- The casting material is usually made of gray cast iron, nodular cast iron and vermicular graphite cast iron
- 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?
- Our country has a national standard for casting tolerance levels. This national standard applies to you in malleable iron, grey cast iron, and ductile iron.
- 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: What's the cause of the choking of the casting?,
- Causes of choking fire:1., casting material in the pouring of gas;
- 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: How can the casting be free of trachoma?
