| Message: | 1.Shanghai Meihong Machinery Manufacturing Co., Ltd.is a casting iron,aluminum castingin one large multi-functional integrated modern enterprise,and devote the high-quality lost wax casting and first-class service for the masses of customers.
2.Shanghai Meihong Machinery Manufacturing Co., Ltd. is specialized in Industry and agriculture,Machinery and industry equipment,Casting processing since established in 10 years ago.So far,our company has established its branch companies in major cities throughout the country.Formed in Rm.503, 1st Building , Wisdom Bay, Rd 6 Yunchuan,Baoshan District,City area,Shanghai,China as the center, the radiation sales system and service network.Details:The principle of investment casting technology or process (FGCP) is to control the ordinary investment casting process, strengthen the nucleation mechanism of the alloy, form a large number of crystal cores in the casting process, and prevent the grain from growing, thus obtaining the average crystal. Uniform, fine, isotropic equiaxed crystal castings with a particle size of less than 1.6 mm, and the grain size of typical fine-grain castings is US Standard ASTM 0~2. Investing in casting refines the grain of the casting, and also reduces the size of the nascent carbide and strengthening phase γ in the superalloy and improves the morphology. Therefore, the outstanding advantages of investment casting are to greatly improve the low cycle fatigue life of castings under medium and low temperature (≤ 760 ° C) conditions, and significantly reduce the dispersion of mechanical properties of castings, thereby improving the design tolerance of cast parts. At the same time, the technology also improves the tensile properties and long-lasting properties of the castings to a certain extent, and the castings have good heat treatment properties.Investment casting technology can also improve the machinability of high-temperature alloy castings and reduce the potential for machining cracks in screw hol |
