Unlike traditional manufacturing machines, 3D printers create objects by cutting or molding. The method of forming physical objects by stacking layers expands the scope of digital concepts from a physical perspective. 3D printer is the preferred processing equipment for shape design requiring precise internal concave or interlocking parts, which can be realized in the physical world. The following is a similar description of people from various industries with different backgrounds and professional skills. 3D printing helps them reduce major cost, time and complexity barriers. Let's take a look at the advantages of 3D printing. The advantages of 3D printing cannot…

One Quenching crack (1) Shape effect. It is mainly caused by design factors, such as small fillet R, improper hole location, and poor section transition. (2) Overheating (overburn). It is mainly caused by inaccurate temperature control or temperature run out, too high process setting temperature, and uneven furnace temperature. Preventive measures include: maintenance, calibration of temperature control system, correction of process temperature, and adding sizing iron between the workpiece and furnace floor. (3) Decarbonization. It is mainly caused by overheating (or overburning), unprotected heating in the air furnace, small machining allowance, residual decarburization layer in forging or preparation heat treatment,…

With the popularization of 3D printing, more and more cases show that 3D printing plays a vital role in various fields. Especially with the continuous introduction of the medical industry, 3D printing will change the traditional medical methods.The following is an inventory of 3D printing applications Intelligent hardware field：3D printing is widely used in UAV, VR, robot and other fields. Automobile manufacturing The spokesman of Rock Automobile Company said that LM3D Swim body printing material is composed of 80% ABS plastic and 20% carbon fiber, so compared with ordinary cars, the car body is significantly reduced. Film and television animation…

As the shell of the server, the cabinet has also been greatly developed with the eruption of cloud products in China, and the market demand is growing year by year. 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…
