     A main field of application for adhesives in medical systems is needle bonding and syringe assembly in high volume production. Optimally matched processes are essential for reliable bonding. Panacol, Hönle and bdtronic partner to ensure that precise adhesive dosing, capillary flow and curing in seconds with UV light work hand in hand.
      黏合劑在醫療行業主要應用於大批量生產的針頭黏接和注射器組裝。優化的生產工藝對於黏接的可靠性至關重要。Panacol、好樂和bdtronic三方合作，確保精確的黏合劑劑量，利用毛細流動以及紫外固化幾秒內完成協同合作。

   As the needles are produced in large quantities rapid and reliable bonding is essential. In addition to their mechanical bond strength, the adhesives used must allow high-precision production and permanent joining and must withstand various sterilization methods. Panacol’s UV curable Vitralit® adhesives exactly meet these requirements.  Vitralit® adhesives are available in various viscosity ranges to perfectly fit the design of the needle hub and fill the gap between the hub and the needle. The material of the hub and needle also affects the choice of the adhesive: Many adhesives are UV-curing, which requires the use of transparent and UV-permeable materials. For materials that block UV light, such as polycarbonates, long-wave LED curable adhesives are recommended.
       由於針頭的生產數量龐大，所以需要快速可靠的黏接。除了黏接強度以外，所選的黏合劑還必須保證高精度的生產和永久性連接效果，並且能夠承受各種消毒方法的考驗，Panacol 的UV固化Vitralit®系列的黏合劑完美匹配這些要求。Vitralit®系列的黏合劑有不同範圍的粘度可供選擇，完美契合針頭和介面的設計，填充針座與針頭之間的間隙。針座和針頭的材質也會影響黏合劑的選擇，紫外固化的黏合劑適用於透明、透紫外線的材料。而對於阻擋紫外線的材料，如聚碳酸酯，則建議選用長波LED固化的黏合劑。

   All Vitralit® adhesives recommended for needle bonding are solvent-free and certified USP Class VI and/or ISO 10993 for use in medical equipment. In addition, high needle extraction forces were measured with all needle bonding adhesives even after several sterilization cycles. For visual quality inspection, fluorescent versions of our medical grade adhesives are also available. 

       針頭黏接的Vitralit®系列的黏合劑均不含溶劑，並且通過USP VI 級和/或ISO 10993 認證，可用於醫療設備。此外，黏合劑在經受多次滅菌迴圈後，仍能保證較高的針頭拔出力。為方便視覺品質檢查，Panacol還提供螢光版本的醫用級黏合劑。

   The choice of the adhesives requires a matching dispensing system for reliable and precise dispensing in a rapid production environment.
選擇黏合劑時還需要考慮匹配的點膠系統，以便在快速生產過程中保證可靠精確的點膠。

The high quality demands required for medical devices, as this needle bonding application, confirms the choice for bdtronic’s volumetric dispensing equipment. With the mini-dis solution provided by bdtronic, dispensing in microliter range is made easy, regardless of the adhesive viscosity. Thanks to the continuous volumetric dispensing, the dispensing is pulsation free ensuring optimal process speed, repeatability and accuracy.

    Finally, the choice of the UV curing equipment depends on the adhesive and the wavelength which triggers polymerization. For needle bonding with Vitralit® products you can use either UV-A or visible LED light.
       最後，紫外固化設備的選擇取決於黏合劑所需的引發聚合的波長。對於應用於針頭黏接的Vitralit®產品，您可以選用UV-A或可見光LED燈。

    Due to a special LED assembly and an own optimized electric power supply, Hönle LED Powerline LC guarantees a high-intensive irradiation for fastest curing and shortest cycle times. In addition, the irradiation time can be selected in a range of 0.01 – 99.99 sec and thus precisely adapted to the process requirements.
       由於採用了特殊的LED元件和優化的電源，好樂LED Powerline LC可以保證高強度照射，以實現最快的固化和最短的週期時間。此外，照射時間可以在0.01–99.99秒的範圍內任意選擇，精確滿足工藝要求。
 

    Hönle LED Powerline heads have a compact design for an easy integration into any production line. The high-intensive, water-cooled LED-UV is suitable for clean room operation. 
    好樂LED燈頭設計緊湊，可輕鬆集成到任何生產線中。高強度、水冷式 LED-UV固化系統適用於無菌室操作。
