      Principio di funzionamento<\/h2>\n

      The working principle of the\u00a0NPD-01 Tester di penetrazione e forza di trascinamento dell'ago<\/strong>\u00a0involves inserting a needle into a specified substrate and recording the forces during the insertion process. The machine operates under the following steps:<\/p>\n

        \n
      1. Inserimento dell'ago<\/strong>: The needle is held securely by the machine and inserted into a substrate (e.g., synthetic skin, rubber) at a constant speed.<\/li>\n
      2. Misurazione della forza<\/strong>: As the needle moves through the substrate, the load cell measures the\u00a0penetration force<\/strong>\u00a0(initial peak force required to break the surface) and\u00a0drag force<\/strong>\u00a0(force required to keep the needle moving through the material).<\/li>\n
      3. Registrazione dei dati<\/strong>: The system records force values at various penetration depths, allowing for a detailed analysis of the needle\u2019s performance.<\/li>\n
      4. Force Profile<\/strong>: The resulting graph helps researchers and manufacturers understand how the needle behaves under different conditions and optimize its design accordingly.<\/li>\n<\/ol>\n

        Il\u00a0NPD-01<\/strong>\u00a0Needle Penetration Force Tester\u00a0<\/strong>can adjust variables such as\u00a0test speed<\/strong>\u00a0(1\u2013500 mm\/min) and\u00a0penetration depth<\/strong>, making it versatile for a wide range of needle types and applications.<\/p>\n
