Product Description大員
It refers to the casting method that 數可the mold is generall樹話y placed above the sealed cruc問小ible, and the crucible is fill北議ed with compressed air, which 愛那causes low pres遠還sure (0.06-0.15MPa) on the sur現街face of molten metal, 資腦so that the liquid meta歌河l rises from the riser to fill the舊高 mold and control the solidi師有fication. With good shri子報nkage and compact casting st妹在ructure, this casting method is 坐醫easy to cast large and c制請omplex thin-walled castings wi機子thout riser, and the metal yield is 樹短up to 95%. No pollution is離機 generated, and it is eas麗她y to realize autom弟綠ation. However, the equipment cost is h短可igh and the production ef在空ficiency is low習白. It is generally used for 呢亮casting non-ferrous alloys.
● Principles
Low-pressure casting妹從 is a casting method that the liquid al著花loy is pressed in花從to the mold cavity fro草這m bottom to top under pressure and熱不 solidified under pressure家森 to obtain castings. The princi美花ple of low-pressure們爸 casting is shown in Figure 1 Principl飛了e of Low Pressure Casting.制視 The sealed crucible is filled with 土風dry compressed air or inert gas呢錯. With the help of the pressure司在 acting on the met朋問al surface, the molten metal is fille司朋d with the mold放空 smoothly from bottom美短 to top along the答也 riser through the r紙作unner. The filling pressure is general鐘舞ly 20-60kPa. When 就技the casting is completely sol票計idified, the gas pres醫城sure on the liqu費市id surface is released,拿月 so that the metal liquid 問小without solidification in th城愛e riser pipe and runner flows into the 相民crucible by its own weight,工時 and then the cast is opened an拍錢d the casting is removed.
