First, the special requirements of welding technology for medical equipment manufacturing

(A) high precision requirements

Medical devices contain a large number of precision parts, such as minimally invasive surgical instruments, cardiac stents, implantable sensors and so on. These parts are tiny in size, complex structure, the welding precision requirements are extremely high. Take cardiac stents as an example, its diameter is usually only a few millimeters, and it is necessary to weld a number of tiny wires into a mesh structure, the position and size of the welding point deviation must be controlled at the micron level, otherwise it will affect the support performance of the stent and the adaptability of the stent within the human body blood vessels. Traditional welding methods are difficult to meet such high-precision requirements, and vacuum brazing furnace can realize high-quality welding of precision parts through precise control of the welding process to ensure the dimensional accuracy and structural integrity of medical devices.

(B) high reliability requirements

Medical devices in the process of use, need to withstand a variety of complex physical and chemical effects, such as frequent operation of surgical instruments, implantable devices in the human body for a long time force and corrosion. This requires that the welded joints have a very high reliability, can work stably for a long time, to avoid loosening, fracture and other problems. The reliability of welded joints not only depends on the welding material and process, but also closely related to the environmental factors in the welding process. Ordinary welding in the atmosphere is prone to porosity, inclusions and other defects, reducing the strength and reliability of welded joints. The vacuum brazing furnace to create a vacuum environment, from the root to avoid these problems, can form a strong, dense welded joints to meet the requirements of medical devices for high reliability.

(C) biocompatibility requirements

For implantable medical devices, such as artificial joints, artificial heart valves, etc., welding materials and processes must meet strict biocompatibility standards. The welding process can not introduce substances harmful to the human body, otherwise it will trigger the body's immune response, causing serious harm to the patient's health. Vacuum brazing furnace in the welding process without the use of chemical brazing agent, to avoid the risk of contamination caused by the brazing agent residue, and high vacuum environment can ensure the purity of the welding material, and effectively meet the biocompatibility requirements of medical devices.

Second, the technical characteristics and advantages of vacuum brazing furnace

(A) high vacuum environment to protect the welding quality

Vacuum brazing furnace through a powerful vacuum system, the furnace air pressure down to a very low level, usually maintained between (10^{-2} sim 10^{-5} text{Pa}), the formation of nearly oxygen-free high vacuum environment. In this environment, the welding material will not be oxidized and nitrogenated with oxygen and nitrogen in the air, effectively avoiding the formation of oxide film on the surface of the welded joint and ensuring the purity of the weld. For titanium alloy, stainless steel and other metal materials commonly used in the manufacture of medical devices, the vacuum environment can significantly improve the strength of the welded joints, corrosion resistance and sealing, to ensure that the performance of medical devices is stable and reliable. vacuum brazing furnace XVACUUM Technology (Jiangsu) Co., Ltd. is equipped with a highly efficient vacuum pumping system and an advanced vacuum monitoring device, which is able to quickly reach and stably maintain the required high vacuum degree It provides a solid guarantee for high quality brazing.

(B) accurate temperature control to realize precision welding

The vacuum brazing furnace adopts advanced heating elements and intelligent temperature control system, which can realize the precise control of welding temperature. Through the high-precision temperature sensor real-time monitoring of the furnace temperature, and the use of intelligent algorithms to automatically adjust the heating power, the temperature fluctuations will be controlled within a very small range. In the welding process of precision parts of medical devices, precise temperature control is crucial. For example, when welding fine parts of minimally invasive surgical instruments, it is necessary to accurately set the heating temperature and the rate of heating up and cooling down according to the characteristics of the material and the melting point of the brazing material to ensure the quality and precision of the welded joints.The high precision of the temperature control of the vacuum brazing furnace of XVACUUM Technology (Jiangsu) Co., Ltd. is able to meet the stringent requirements of the manufacture of medical devices for precision welding, effectively reduce the welding deformation, and guarantee the The dimensional accuracy of the parts.

(iii) No brazing agent residue to ensure biological safety

Unlike traditional welding methods, vacuum brazing does not require the use of chemical brazing flux in the welding process. Although chemical brazing flux can promote welding to a certain extent, the residual brazing flux may have a negative impact on the performance and biocompatibility of medical devices. Vacuum brazing furnace utilizes the wetting, spreading and capillary action of liquid brazing flux under vacuum environment to realize soldering, avoiding the risk of contamination caused by brazing flux residue and ensuring the biosafety of medical devices, which is especially suitable for soldering and manufacturing of implantable medical devices.
