Enray
Hunan enrui specializes in customized production of ceramic sintering furnaces, silicon carbide sintering furnaces, mobile phone 4.5G/5G, wireless charging and other technologies are attracting attention from the industry. signal shielding and heat dissipation will be technical problems in the industry. Ceramic as a new material for mobile phone shell, may be the best solution! "From microcrystalline zirconium nano-ceramic powder to mobile phone ceramic body, it is mainly subjected to dry pressing (or injection, casting, etc.), degumming and sintering, grinding and polishing, CNC processing, etc., just like Sun Dasheng gestating and forming in stone, Taishang Laojun Bagua furnace firing, and 991 81 difficult to polish into Buddha, which is extremely difficult! So, can do mobile phone ceramic shell,

From microcrystalline zirconium nano-ceramic powder to mobile phone ceramic body, it is mainly subjected to dry pressing (or injection, casting, etc.), degumming and sintering, grinding and polishing, CNC processing, etc., just like Sun Dasheng's gestation and forming in stone, Taishang Laojun Bagua furnace firing, and ninety-nine eighty-one difficulty in grinding into Buddha, which is extremely difficult! Therefore, it is nothing to be able to make a ceramic case for a mobile phone (a joke). Below we understand the processing technology of ceramic mobile phone:
”
1. dry pressing molding
Dry pressing molding, also known as compression molding, is a method in which microcrystalline zirconium nano-ceramic raw materials that have been granulated, have good fluidity and are properly prepared are put into a mold, and the powder is made into a certain shape body by applying external pressure to the plunger of the press. Dry pressing molding reduces the subsequent sintering time due to the moisture content of the powder below 7%.
2. sintering
The green body is put into a sintering furnace at a high temperature of more than 2000 degrees C to sinter, reduce the pores in the forming body, enhance the combination between particles, improve mechanical strength, and obtain a molded ceramic sintered part with a hardness comparable to sapphire.
3. grinding and polishing
Grinding is mainly a kind of process to achieve rapid thinning, and the mechanism of material stripping in the grinding process of ceramics is mainly rolling crushing. Polishing is the use of fine abrasive elastic plastic polishing machine, etc. on the surface of the workpiece friction, so that the surface of the workpiece to produce plastic flow, generating fine chips. Due to the hardness of microcrystalline nano-zirconia ceramics, grinding and polishing takes a long time, which is 350 minutes in the video.
4. CNC Machining
Ceramic CNC machining is mainly used for the body finishing treatment, is the phone body curve more soft, look and feel more comfortable. In the process of ceramic grinding, the brittle peeling of materials is completed by the formation or extension of voids and cracks, peeling and fragmentation. Due to the hardness of microcrystalline nano zirconia ceramics, it is necessary to use surface treatment or diamond material CNC tool processing.
5. mobile phone ceramic shell finished product
After hundreds of complex processes, as well as laser, PVD, AF and other surface post-processing, the final crystal structure is uniform, shiny and dazzling mobile phone ceramic body.
Hunan enrui automation equipment co., ltd. has in-depth cooperation with domestic well-known mobile phone original suppliers, including mobile phone heat dissipation ink and graphene heat dissipation film. Professional custom production of ceramic sintering furnace, high temperature graphitization furnace.
