low pressure aluminum alloy casting
Low pressure aluminum alloy die casting(LPDC) also could call her Counter-Gravity Casting CGC
Counter-Gravity Casting (CGC), and for chinese, we name it mostly Low pressure aluminum alloy die casting(LPDC) mostly.
CGC/LPDC is the application of Pascal principle in foundry production. As far as its process is concerned, it is a liquid forming method between pressure casting and gravity casting. The driving force of the alloy liquid filling mold is opposite to the direction of gravity, and the alloy liquid flows in the opposite direction to the gravity. Compared with gravity casting, the fluid state of the melt during the liquid forming process of anti-gravity casting can be controlled, and the solidification and shrinkage capacity can be enhanced by the action of external force. Therefore, the process can achieve stable liquid filling and compact structure of the casting. Casting defects can be effectively controlled and are the preferred method for producing high quality castings.
Due to the existence of external driving force, CGC becomes a controllable process. In the process of filling metal liquid. Different filling speeds can be realized by controlling the magnitude of the applied force, and such filling could meet the different process for each parts’ requirements. At the same time, after filling completed, the external force can be continuously increased, the casting can be solidified under a large force, the feeding ability of the molten metal is improved, and casting defects such as shrinkage holes, pores and pinholes are reduced.
Low-pressure casting is a very important casting process in casting aluminum alloys, because of its unique process and high quality stability, low-pressure casting is becoming more and more popular. Many cast aluminum alloys are cast at low pressure. Low-pressure casting has many advantages, such as a wide range of materials, a wide range of surface treatments, heat treatment, easy casting, and more.
Low pressure aluminum alloy casting, with its special characteristics and easy pouring, its widely used for many parts, and material is also widely be choosen, like: AlSi7Mg, AlSi7Mg is a common and used aluminum alloy grade. It is called differently in international countries, such as in China ZL101, ISO-Al-Si7Mg (Fe), Japan AC4C, European standard is 42100, Germany is alsi7mg, Britain is LM25, USA is A356. Of course, they are all the same. This kind material could do heat treatment T5, T6 to increasing mechnical needs, and its good applied for parts in low pressure, you’ll ask why?
The technical characteristics of low pressure casting:
1. The pressure and speed during casting can be adjusted, so it can be applied to various molds (such as metal type, part need sand core, etc.), casting various alloys and various sizes of castings. 0.02kg-30kg.
2. The metal liquid filling type is stable, and there is no splashing phenomenon, which can avoid the entrapment of gas and the flushing of the type wall and the core, and improve the qualification rate of the casting.
3. The casting is crystallized under pressure. The casting has compact structure, clear outline, smooth surface and high mechanical properties, which is especially beneficial for the casting of large thin or thick-walled parts.
4. Save the shrinking riser and increase the metal utilization rate to 90% to 98%.
5. Low labor intensity, good working conditions, simple equipment, easy mechanization and automation.
