High Precision Needle Pierce Testing Instrument For Vial Stopper ISO 7886 Testing Machine

NPT-01 Needle Puncture Tester  

NPT-01 Needle Puncture Tester can be equipped with multi types of needles and different types of sample holding jigs. By its professional program, it meet demands of needle puncture testing across various materials.

Application

The puncture force test plays an important role in guaranteeing the safety, reliability, and performance of a wide range of products, such as hypodermic needles, artificial skin, rubber stopper, protective glove, protective clothing, medical closure, infusion bag film, etc.

Needle puncture testing is a process that simulates the penetration of a needle like object into a material to measure its resistance and response. This test is necessary in ensuring the integrity and safety of materials, particularly those that require a proper level of puncture resistance.  This testing also helps in maintaining consistent quality levels, guiding product design and improvement.

Principle

A chosen needle is connected with the loadcell and a specific substrate or sample is placed in a stationary support on the tester base. The needle is moved at a constant speed until it punctures the material sample. The force is recorded as the puncture force.

Features and Benefits 

1. Equipped with a PLC control unit and a user-friendly 7-inch HMI touch screen. 

2. Precision ball screw and stepper motor for accurate and consistent tests. 

3. Variable test speed capability allows for flexible testing. 

4. Offers multiple sample jigs and needle types. 

5. Safety features such as position restrictors and overload protections. 

6. Automatic returning function after test to save operation time. 

7. A dot matrix type microprinter is embedded for long-term data keeping.
