Process for manufacturing middle frame of mobile phone by liquid metal die-casting molding technology

Abstract

The invention discloses a process for manufacturing a middle frame of a mobile phone by liquid metal die-casting molding technology. The appearance structure of the middle frame of the mobile phone ismade of a bulk amorphous alloy, namely, liquid metal. The glass forming ability (GFA) of the bulk amorphous alloy is more than 1 mm during copper mold pouring, the solid microstructure of the bulk amorphous alloy is of a short-range ordered and long-range disordered arrangement structure, and the solid microstructure is similar to microstructure in liquid and similar to the microstructure of theglass, so the bulk amorphous alloy is further called liquid metal or metallic glass. The process for manufacturing the middle frame of the mobile phone by the liquid metal die-casting molding technology comprises main technological processes of full vacuum die casting of the liquid metal, machining treatment 1, combination of aluminum/magnesium middle plate, machining treatment 2, NMT, machining treatment 3, polishing, and PVD. According to the process for manufacturing the middle frame of the mobile phone by the liquid metal die-casting molding technology, the middle frame of the liquid metalmobile phone has high strength, high hardness, high elasticity, abrasion resistance, corrosion resistance, almost no plastic deformation, low thermal conductivity and attractive and high-grade appearance, and the production of high performance, high efficiency and low cost is achieved.

Description

technical field [0001] The patent of the present invention relates to a processing method of communication parts, specifically a process for designing / producing middle frame parts of mobile phones using liquid metal technology. Background technique [0002] There are two traditional manufacturing methods for the middle frame of the mobile phone, that is, the anodized surface treatment is carried out after the traditional machining method is cut and formed (the whole piece of aluminum is cut and cut by the CNC machine tool and then the anodized surface is treated), The second is forging aluminum + CNC + anodic oxidation surface treatment (forging blanks first, then cutting and cutting the material through CNC machining and then anodizing surface treatment); the two methods have certain limitations in material application and surface specular highlight effect, and at the same time Manufacturing costs are higher. [0003] Bulk amorphous alloy usually refers to its glass formin...
