  The aluminum profile industry has become a very mature industry. The aluminum density is only 2.7g/cm. Although it is soft, it can be made into duralumin, hard aluminum, rust-proof aluminum, cast aluminum and other aluminum alloys. Nowadays, the application of aluminum housing is very extensive, let us see how to judge the quality of aluminum housing? 1. The text on the surface of the aluminum shell material is generally printed with imported inkjet codes. The text is clear, and the trademark identification, manufacturer, address, telephone, etc. are generally clearly marked. The text on the surface of the real fake aluminum veneer material is mostly printed by ordinary printing machines. Blur, its manufacturer, display etc. 2. The aluminum outer packaging material is made of high-quality raw materials, with high technical precision, and the surface and inner layers feel smooth and even. 3. The wall thickness of the aluminum shell is uniform, the aluminum veneer material is tight...

  The   fr4 epoxy board   is a code for the grade of flame-resistant material, which represents a material specification that the resin material must be able to extinguish itself after the burning state. Epoxy resins generally refer to organic polymer compounds containing two or more epoxy groups in the molecule. Except for a few, their relative molecular mass is not high. The molecular structure of epoxy resin is characterized by the active epoxy group in the molecular chain. The epoxy group can be located at the end, middle or in a cyclic structure of the molecular chain. Because the molecular structure contains active epoxy groups, they can undergo cross-linking reactions with various types of curing agents to form insoluble and infusible polymers with a three-way network structure. The advantages of cnc machining fr4 epoxy board 1. Various forms: various resins, curing agents, and modifier systems can almost adapt to the requirements of various applications on th...

  The   sprue bush   is the   connecting member between the machine nozzle and the mold face ，or can also be described as a   flow path component   that allows molten plastic material to be injected from the nozzle of the injection molding machine into the interior of the mold,and provides suitable aperture through which the material can travel on its way to the mould cavity or the start of the runner system in multi-impression molds.The bolt-type nozzle is a nozzle that is fixed by two bolts and is fixed by bolts to prevent the nozzle from falling off due to the injection pressure. The  sprue bushing  is often used as the grab point in robotic removal of parts, sprues and runners. This requires that the sprue be rigid enough to resist the pressure of the robot fingers as well as the extraction forces. With conventional steel sprues this measure is most often met by added cooling time to the mold cycle. HG Precision will again reduce the sprue coo...

  1. Overview of  CNC Machining Based on the development of a milling machine automatic processing equipment, the two processing technology is basically the same, the structure is similar. CNC milling machine   with cutter base is called machining center. 2. The scope of function of CNC Machining Good adaptability and flexibility in processing, and can process parts with particularly complex contour shape or difficult to control size.High processing precision, stable and reliable processing quality, numerical control device pulse equivalent is generally 0.001mm, high precision numerical control system can be up to 0.5 m, numerical control processing also avoid operator error.Production automation degree is high, can reduce the labor intensity of the operator.Conducive to production management automation. 3. Classification of CNC Processing in the factory There are two kinds of CNC in the factory: Ordinary CNC: less than 8000 RPM, can be a large tool, suitable for milling,...

  As we know,every   CNC Machinery Parts   products need to test and check before selling out.And they would be tested repeatly.Now we will say about the   Current Workshop Unconventional Test  for the   CNC machining parts . 1: Detection of inner diameter When the workpiece can not be directly measured with the inside micrometer, the following methods can be referred to for inspection. For the workpiece with wall thickness less than 30, first measure the outer circle size of the workpiece, and then measure the wall thickness size with a sharp divider, that is, the inner hole size = the outer circle size -2* the wall thickness size. This method can be controlled within 0.005., Measure the size of the hole by means of the table. First measure the size of the workpiece's outer circle. Then measure the size of the outer circle and the wall thickness with the table.This method can also be controlled within 0.005. Check the hole size with the plug gauge of corre...

  Aluminum alloy is widely used in product shells because of its high strength, light weight, good corrosion resistance and easy processing. Aluminum alloy shells have been widely used in daily life, such as: aluminum alloy shells for mobile power supplies, wireless charging aluminum alloys Shell, Bluetooth audio aluminum alloy shell, headset aluminum alloy shell, etc. The aluminum alloy shell also needs to pay attention to maintenance and maintenance, so as to make the aluminum alloy shell more durable and beautiful. So how to maintain the aluminum profile shell? 1. When there are burrs on the surface of the workpiece, be sure to remove the burrs before measuring, otherwise the measuring tool will be worn and the accuracy of the measurement results will also be affected. 2. After using the measuring tool, wipe clean the surface stains and aluminum chips, loosen the fastening device, and apply anti-rust oil on the measuring surface when it is not used for a long time (more than 1 m...

  With the development of society and the advancement of technology, equipment manufacturers have higher and higher requirements for the internal quality and appearance of aluminum alloy shell parts. In order to meet the ever-increasing internal quality and appearance requirements, manufacturers have adopted various methods to improve the internal and external quality of aluminum alloy shell parts. In production practice, the external quality of aluminum alloy parts is often improved by anodizing surface treatment process. After anodizing treatment, a layer of anodic oxide film with a certain thickness, strength and beautiful appearance can be formed on the surface of the aluminum alloy shell parts. Through electron microscope observation, it can be found that the structure of the anodic oxide film is honeycomb, and the center has a micropore that grows perpendicular to the surface of the aluminum substrate, showing the beauty of the shape that cannot be seen in other surface treat...
