Information
In the machining industry, sheet metal processing technology is very important. This process can decorate and design the surface of the product, and has a maintenance role. In custom precision sheet metal machining, common surface treatment methods include electroplating, spray painting and other types of surface treatment. Follow a medical sheet metal processing company to learn how to properly handle the surface treatment of sheet metal parts.
Machinery industry Parts processing
1. Electroplating includes: hot dip galvanizing (color zinc, milky white zinc, dark blue zinc, gray black zinc), nickel plating, stainless steel, etc. The protective layer mainly exists on the surface of the raw material to maintain and decorate the pattern.
2. Spray painting includes spraying and electrostatic powder spraying. After the bending process of precision sheet metal processing is completed and the raw materials are prepared, a spray gun is used to spray architectural coatings on the surface of the sheet metal product, which produces a coating on the surface of the product. After drying, it has a protective effect.

3. Other surface treatment methods: anodizing, chromium trioxide solution, metal drawing, sandblasting, air oxidation and other common problems in sheet metal processing surface treatment operations. 1. All electrochemical solutions should be carried out under the conditions of the components, because the chemical solution will be trapped in the gaps of the components during the whole process, leading to corrosion and oxidation.
4. Slender cylinders (both long and short diameters greater than 2 times the diameter) are generally not suitable for electrochemical solutions because there is no film on their inner surface; In special cases, professional sheet metal processing plants can adopt unique countermeasures to meet the requirements.
5.Due to the assembly of grooves or tiny holes (usually refers to the depth of more than 2 times the diameter or opening distance, but excellent processing technology may not be limited), the inner surface is not easy to be completely covered by electroplating to improve the adhesion of the coating film.
How to optimize the design of medical sheet metal processing?
1. Blanking. As far as blanking is concerned, the blanking of medical sheet metal processing usually refers to the separation of sheet metal materials by stamping dies. This link is usually applied to the processing of parts with relatively simple shapes to achieve high precision in processing shapes and to reduce material waste to a large extent. In this link, the shape of the sheet metal must first be controlled. In the corner area of the outer hole and the inner hole of the stamping, the arc should be set to make the corner excessive to avoid sharp corners, reduce the mold cracking problem caused by improper subsequent heat treatment, and affect the subsequent sheet metal construction. Then, punching and its small value should be optimized. Usually when stamping sheet metal parts, if the stamping size of the sheet metal parts after stamping is too small, then the load of the punch will be greatly reduced. However, if it is too small, the pressure data of the precision stainless steel sheet metal processing die will suddenly increase, thus affecting the quality of the actual die. For example, in this link, the punching of sheet metal should be set according to different sheet metal load targets. In the basic state, the length of the hole diameter should be greater than twice the hole spacing and greater than 3.00mm, and then in the actual process application should avoid the cantilever and groove on the blanking part of the setting too narrow or too long, to improve the strength of the die blade, and control the cantilever groove width greater than 200 sheet metal thickness.
2. The bending link usually refers to the process of preventing and controlling the sheet material on the bending equipment, making the sheet elastic deformation through the pressure of the upper die or the lower die, and then plastic deformation according to the actual design scheme. In the application process of this link, different parts should be selected according to the actual design requirements, and the actual bending operation should be determined according to the thickness of the sheet material. According to actual bending experience, local abnormal deformation is easy to occur during the bending process, which affects the appearance quality and practical application of sheet metal parts. Therefore, in the actual operation process, if the bending process is to be optimized, the operator should make the incision in advance according to the actual situation to avoid the problem of subsequent deformation. At the same time, when parts need to be bent multiple times, a comprehensive estimate should be made in all bending operations to avoid the impact of medical sheet metal processing bending operations on the subsequent bending process, so as to achieve the expected sheet metal design goals.
Production mode of medical sheet metal frabricating plant 2024年05月14日
Production mode of medical sheet metal processing plant Medical sheet metal frabricating operations are carried out in many areas of work, including various processing steps, such as stamping and material bending. in the process of performing these processing procedures, the operator must pay attention to whether the parameters are accurate and whether the application method meets the requirements. In addition, what exactly is the production model of large-scale sheet metal processing? Let's take a look!   Production mode of medical sheet metal frabricating: 1. The manipulator is equipped with a suction cup to suck up the steel plate and automatically identify the thickness (thickness measuring equipment with rollers). The thickness of the steel plate must meets the requirements of the procedure before it can enter the next process. 2. Put the steel plate on the CNC machine tool for hole punching and blanking, the brush on it will maintain it from being scratched, when the steel plate is moved to this position, the mold will automatically punch the hole, complete the sheet metal blanking process. The CNC machine has the function of automatically modifying and supporting the plates, which greatly improves the utilization rate of wood. 3. Move it to the automatic folding machine and bend the steel plate according to the program. After the parts are completed, the whole process of sheet metal frabrication from steel plate to finished sheet metal does not need manual control and will not cause human deviation, so that the product consistency is very good, not only the pass rate and efficiency are extremaliy high, but also the plate utilization rate is very impressive  However, it should be noted that during sheet metal processing, if the investment is to be reduced, the staff needs to complete the workflow in strict accordance with the production specifications. Therefore, before each application, we need to review the application status of the materials, and if the review is not passed, we cannot handle it casually. Six points that should be paid attention to in medical sheet metal frabrication The application of aluminum shell is also very extensive, I have to say, this is also one of the very common manufacturing processes in professional medical sheet metal frabricating customization, so what matters need to be paid attention to in medical sheet metal processing aluminum shell? Let's take a look 1. Do not use the measuring claw tip of the caliper as a marking needle, compass or other tools, do not manually shake the two PAWS or use the measuring tool as a splint; 2. Do not use oil stone and sandpaper to polish the measuring surface, measuring surface and marking part, unless it is the measurement maintenance personnel, it is prohibited to disassemble, modify and repair the measuring tool. 3. When the surface of the workpiece has burrs, the burrs must be removed before measurement, otherwise the measuring tool will be damaged and the accuracy of the measurement results will be affected; 4. Do not touch the measuring surface of the measuring tool with your hand, because the wet and cold dirt such as sweat on your hand will pollute the measuring surface and make it rusty. Do not mix the measuring tool with other tools and metal substances to prevent damage to the measuring tool; 5. The storage place of measuring tools should be kept clean, dry, free of vibration and corrosive substances, and away from places with large temperature changes or areas with magnetic fields. The measuring tools stored in the measuring box should be clean and dry, and no other debris should be stored; 6. After the measuring tool is used, clean the dirt and aluminum chips on the surface, loosen the fastening device, and apply anti-rust agent on the measuring surface when it is not used for a long time. It is recommended that full-time personnel be responsible for keeping the annual inspection records of measuring tools detected by authoritative enterprises.
