Advantages and disadvantages of common electroplating layers in medical microneedle electroplating
2024/09/11
Medical microneedles are tiny needle-like devices that are widely used in medical cosmetology and some medical fields, so they are also called cosmetic microneedles, puncture needles, etc. They have the advantages of minimally invasive, precise, safe and efficient. Due to the wide application and particularity of medical microneedles, the electroplating layer of medical microneedles plays an important role in their application. The following introduces the common electroplating layers of medical microneedle electroplating processing. Chrome plating Hard chrome plating is a common electroplating material with high hardness, wear resistance and good corrosion resistance. It can improve the surface hardness and wear resistance of medical microneedles and extend their service life. However, chromium is a heavy metal that may pose potential risks to human health. Therefore, when using medical microneedles plated with hard chrome, it is necessary to ensure that they comply with relevant safety standards and regulations. Titanium plating Titanium is a metal with good biocompatibility. Titanium plating can improve the biocompatibility of medical microneedles and reduce irritation and adverse reactions to the human body. Titanium also has high strength and corrosion resistance and can withstand certain pressure and chemical erosion. Silver plating The silver plating layer has good conductivity and antibacterial properties. In medical applications, silver-plated medical microneedles can be used for electrical stimulation therapy or as biosensors, while also reducing bacterial growth and the risk of infection. However, the silver layer is easily oxidized in the air, and appropriate protective measures need to be taken to maintain its performance. Gold plating The gold-plated layer has excellent conductivity, chemical stability and biocompatibility. It can be used to make high-precision medical microneedles, such as those used for nerve stimulation or cell culture. The cost of the gold-plated layer is high, but its performance is stable and its service life is long.
Since its establishment, HYP has focused on the barrel plating of precision electronic parts of copper-based and iron-based materials, so it has a good technical foundation and sufficient conditions for the surface treatment of precision probes. A long period of research has been conducted on microneedles, and the necessary tanks and fixtures are equipped to prevent the microneedles from being damaged and lost during the electroplating process, while also ensuring the excellent bonding strength and good uniformity of the product's coating.
