According to the data released by the Information and Communication Development Department of the Ministry of Industry and Information Technology, from 2017 to 2019, the number of server cabinets in use nationwide was 1.66 million, 2.262 million and 3.145 million respectively. In the future, with the maturity of 5G and other network technologies, the server cabinet market will continue to show a steady growth trend. Requirements for server cabinet The…

The mold uses more materials in production, has a long manufacturing cycle, and has high processing costs, especially for sophisticated and complex molds and large molds. Therefore, it is necessary to maintain the mold before, during and after production. The quality of mold use and maintenance has a great impact on casting quality and mold service life. The purpose of mold maintenance is to improve production efficiency, reduce production costs, reduce failures and quality problems, and extend mold service life How to maintain the mold? Protection of mould corrosion The maintenance is multifaceted. If the storage area is poorly ventilated…

Common injection materials for injection molding include ABS, PC, PE, PP, PS, PA, POM, etc. Different materials have different properties. When selecting processing materials, you can choose them according to the performance requirements of the product itself ABS plastic ABS plastic is a terpolymer of acrylonitrile (A), butadiene (B) and styrene (S), with light ivory color, opaque, non-toxic and tasteless. ABS is one of the most widely used engineering plastics because of its easy availability of raw materials, good comprehensive performance, low price and wide use. Properties of ABS plastics: 1. High mechanical strength, strong impact resistance and good creep…

Moulds are various molds and tools used in industrial production to obtain required products by injection molding, blow molding, extrusion, die-casting or forging molding, smelting, stamping and other methods. In short, a mold is a tool used to make molded articles. This tool is composed of various parts. Different molds are composed of different parts. It mainly realizes the processing of article shape by changing the physical state of the formed materials. Mold composition The die has a specific contour or cavity shape, and the contour shape with the cutting edge can make the blank separate according to the contour…

In recent years, with the improvement of the precision requirements of the market for sheet metal parts, precision sheet metal processing has begun to enter the center of the stage of the sheet metal industry. As a key production process in the machinery manufacturing industry, precision sheet metal parts are widely used in rail transit equipment, precision machine tools, automobile manufacturing, medical equipment, household appliances, etc., which is an important embodiment of China's intelligent manufacturing. What is the difference between precision sheet metal processing and ordinary sheet metal processing? Differences between precision sheet metal working and ordinary sheet metal working…

The term CNC stands for "computer numerical control," and CNC processing is defined as the subtraction manufacturing process, which typically uses computer control and machine tools to remove layers of material from inventory pieces (called blanks or workpieces) and produce custom-designed parts. This process is applicable to various materials, including metal, plastic, wood, glass, foam and composite materials, and has been applied in various industries, such as large-scale CNC machining and CNC finishing aerospace parts CNC machining features 01 High degree of automation and very high production efficiency. Except for blank clamping, all other processing procedures can be completed by CNC…

With the development of modern NC machining towards high speed, high precision, high intelligence, high flexibility, high automation and high reliability, higher requirements are put forward for the machining ability and efficiency of the machining center, so the multi axis NC machining technology has been developed unprecedentedly What is a multi axis machine tool? Multi axis machine tool refers to simultaneous processing on multiple coordinate axes of a machine tool, and simultaneous coordinated movement can be carried out under the control of a computer numerical control system. Multi axis NC machining can simultaneously control the linkage of more than 4…

Surface treatment is to clean, clean, deburr, degrease and scale the workpiece surface to meet the corrosion resistance, wear resistance, decoration or other special functional requirements of the product. The surface treatment of metal castings mainly includes mechanical polishing, chemical treatment, heat treatment, spraying, etc. What are the common surface treatment processes? The appearance of the processed workpiece is inseparable from the design, color, material and process, and the surface treatment process is the most direct embodiment of the product appearance. The surface treatment can improve the product appearance, texture, function and other aspects of performance. The commonly used surface…

CNC machine tools appeared as early as the 1940s, when it was the first time to use motors to control the movement of existing tools, thus realizing the milling process. With the emergence and development of computer technology, the ability of analog computer is enhanced, which promotes the rise of CNC machining According to the different cutting direction and structure mode, CNC machine tools are divided into milling machines and lathes to meet the processing requirements of different curved surfaces CNC lathe The lathe is the processing method of workpiece rotation. The fixed longitudinal horizontal tool movement is used to process…
