The metal casing is mainly produced by CNC machine tools
At present, the main processing technologies for mobile phone cases include; Aluminum extrusion+CNC machining& Ldquo; Die casting+CNC machining; And&quo; Stamping+CNC machining; Three ways. No matter which process is used, the processing of metal shells cannot be separated from CNC equipment.

Market demand for high-speed drilling machine tools
In CNC machining equipment for mobile phone casings, high-speed drilling and tapping machines are one of the most important production equipment. The efficiency of high-speed drilling and tapping centers is higher, ten times that of ordinary machining centers, so high-speed drilling and tapping machines are often used in the production of mobile phone cases.

Performance and advantages
Liquid metal is an amorphous alloy with a molecular structure different from the crystalline structure of traditional metals, similar to the molecular structure of glass, commonly known as "; Metal glass;.
&Nbsp;
nine thousand and nineteen
Liquid metal combines the excellent mechanical properties of metals with the easy forming and processing characteristics of glass. It has the characteristics of high strength, high hardness, good elasticity, corrosion resistance, and low melting point, making it easy to process plasticity. Specifically, liquid metal processing can be formed in one go without the need for tedious post-processing procedures to obtain products that are close to their intended use.

Processing equipment
In liquid metal processing equipment, vacuum die-casting machines account for the largest proportion of investment. Taking the fundraising project of Taiyi Yingtuo's liquid metal production line as an example, it aims to produce liquid metal products within 4 years of reaching the production deadline1107600 pieces, with equipment investment of about 300 million yuan, of which vacuum die-casting machine investment is about 217 million yuan, accounting for 73%.
