 Vacuum precision casting is a casting process in which metals are smelted, poured and crystallized in a vacuum chamber. It can reduce the gas content in the metal and prevent metal oxidation and trachoma. Demanding castings can be produced in this way.  vacuum casting services The cost of vacuum casting is high, and it is generally used for high-quality castings, and the casting mold should not contain volatiles. Vacuum precision casting is to insert the mold gate (or liquid riser) into the molten metal, and then the mold is evacuated to make the mold cavity become negative pressure. The liquid riser) rises and fills the mold, solidifies and forms, thereby obtaining the casting method of the casting. The process principle of vacuum precision casting is to put the investment mold into the sealing cavity, lower the sealing cavity, immerse the runner in the liquid metal, and then start the vacuum pump to evacuate the sealing cavity, and the liquid is released at the same time. After the casting in the shell is solidified, the vacuum state is released, the molten metal remaining in the flow channel is retued to the fuace, and the vacuum casting casting is obtained by cleaning sand. According to the pressure difference established by the vacuum casting process, vacuum precision casting can be divided into direct casting method and special vacuum method:  like:Take advantage of the technical advantages of vacuum casting Benefits of vacuum suction castingHow to choose a trustworthy casting service company?,vacuum casting services ...ادامه مطلب

The perish-casting method is really a approach when the three components of die-casting unit, pass away-casting mold and alloy are organically combined and used comprehensively. die cast companies ，The procedure of stuffing the cavity with steel during die casting is actually a procedure of unifying approach factors including strain, rate, temperatures and time. Simultaneously, these approach variables effect one another, limit the other person, and accentuate the other. Only by correctly choosing and changing these aspects and causing them to be harmonize can the anticipated effects be obtained. Consequently, in the perish-throwing method, not simply should we observe the quality of your casting composition, the sophisticated nature of the perish-casting mildew, the efficiency and architectural quality of the pass away-casting device, the adaptability of your selection of die-throwing alloys and also the standardization of the smelting approach more attention ought to be paid out to strain, temperature and time. as well as other method parameters enjoy an important role in casting top quality. From the expire throwing process, focus needs to be paid for towards the powerful power over these parameters.   like：What should be paid attention to in the die casting process?Do you know the quality of metal die castingWhat are the characteristics of die casting processing   ,die cast companies ...ادامه مطلب
