Application

NPT-01 Needle Puncture Tester offers versatility with its ability to accommodate various types of needles and sample holding fixtures. Its advanced programming ensures it meets the diverse requirements of needle puncture testing across different materials.

Puncture force testing is crucial for ensuring the safety, reliability, and effectiveness of a wide array of products, including hypodermic needles, artificial skin, rubber stoppers, protective gloves, protective clothing, medical closures, infusion bag films, and more. This testing procedure simulates the penetration of needle-like objects into materials to gauge their resistance and behavior. It is essential for verifying the integrity and safety of materials, especially those requiring specific levels of puncture resistance. Moreover, it aids in maintaining consistent quality standards and provides insights for product design enhancements.

Test Process

 

The selected needle is linked to the load cell, while a designated substrate or sample rests on a stationary support on the base of the tester. The needle moves at a steady pace until it punctures the material sample, and the force exerted is recorded as the puncture force.
