With the continuous development of medical technology, the accuracy and reliability requirements of medical devices are becoming higher and higher. As an advanced metal forming technology, the application value of high precision warm forging technology in the field of medical equipment has become increasingly prominent. This paper will discuss the application value of high precision warm forging in the field of medical devices from the aspects of material properties, manufacturing accuracy and production efficiency.
Improvement of material properties
Strength and toughness: Through the precise control of heating temperature, forging speed and cooling speed and other process parameters, high-precision warm forging process can eliminate the internal defects of metal materials, fine grains, thereby improving the strength and toughness of the material. This enables warm forging forgings to withstand greater loads and shocks, meeting the needs of medical devices in high-intensity working environments.
Corrosion resistance: Medical devices are often exposed to various chemicals and body fluids during use, so they need to have good corrosion resistance. The high precision warm forging process can improve the corrosion resistance of the material by optimizing the composition and microstructure of the material, thus extending the service life of the medical device.
Biocompatibility: Medical devices, as items in direct contact with the human body, need to have good biocompatibility. By controlling the chemical composition and microstructure of the material, the high precision warm forging process can reduce the biological toxicity of the material and improve its compatibility with human tissue, thereby reducing the adverse reactions of the medical device to the human body during use.
Improved manufacturing accuracy
Dimensional accuracy: The high precision warm forging process adopts die forming, which can achieve near net forming of forgings and reduce subsequent machining allowance. By optimizing the mold design and manufacturing process, the dimensional accuracy of the forgings can be controlled at the micron or even nanometer level, meeting the high precision requirements of medical devices.
Shape complexity: High precision warm forging processes can produce forgings with complex shapes and high precision requirements. Through the combination of computer aided design (CAD) and computer aided manufacturing (CAM) technology, the three-dimensional solid modeling of the mold and numerical control processing can be realized, so as to manufacture various shapes of complex medical device parts.
Surface quality: High precision warm forging process can improve the surface quality of forgings, such as finish, flatness, etc. By optimizing process parameters and mold design, the surface roughness of forgings can be controlled at nanometer level, so as to improve the appearance quality and performance of medical devices.
Increased productivity
Automated production: High-precision warm forging process can be combined with automation technology to realize the automation and information of the production process. Through the introduction of advanced technologies such as robots, the Internet of Things, and artificial intelligence, automated operation of production lines and real-time monitoring of data can be achieved, improving production efficiency and quality stability.
Mass production: High precision warm forging process is suitable for mass production, which can reduce production costs and improve production efficiency. By optimizing the production process and equipment configuration, mass production of medical device parts with consistency and stability can be achieved.
Fast response to market demand: High precision warm forging process has the characteristics of flexibility to quickly adjust production plans and product specifications according to market demand. This enables medical device manufacturers to respond to market demand in a timely manner with new products that meet industry standards.
The application value of high-precision warm forging in the field of medical devices is mainly reflected in the improvement of material properties, manufacturing accuracy and production efficiency. With the continuous development of medical technology and the constant change of market demand, the quality and performance of warm forging process and forgings will be put forward higher requirements. Therefore, we need to continue to increase research and development efforts to optimize production processes, improve material utilization and reduce production costs to meet market demand and promote the sustainable development of the medical device field.
