Polymeric Tube Finish and Dimension

Tubes made from polymeric material are commonly used in many industries ranging from automotive, medical, electrical, to many other categories. In this study, medical catheters made of different polymeric materials were studied using the Nanovea 3D Non-Contact Profilometer to measure surface roughness, morphology, and dimensions. Surface roughness is crucial for catheters as many problems with catheters, including infection, physical trauma, and inflammation can be linked with the catheter surface. Mechanical properties, such as coefficient of friction, can also be studied by observing surface properties. These quantifiable data can be obtained to ensure the catheter can be used for medical applications.

Mechanical Properties of Catheter

Catheters that are widely used in the medical industry have very important roles and require precise characterization in order to make sure that they function appropriately. Due to their wide number of applications, catheters have varying levels of stiffness, frictional properties and composition. Since catheters are inserted inside the human body (and sometimes outside) precisely categorizing a catheter based on its properties is important. To make sure that a catheter is made correctly and suits the application it was created for professionals in the medical supplies manufacturing industry can benefit greatly by quantifying the mechanical properties of catheter tubes.

Mechanical Properties of Silicon Carbide Wafer Coatings

Understanding the mechanical properties of silicon carbide wafer coatings is critical. The fabrication process for microelectronic devices can have over 300 different processing steps and can take anywhere from six to eight weeks. During this process, the wafer substrate must be able to withstand the extreme conditions of manufacturing, since a failure at any step would result in the loss of time and money. The testing of hardness, adhesion/scratch resistance and COF/wear rate of the wafer must meet certain requirements in order to survive the conditions imposed during the manufacturing and application process to insure a failure will not occur.

Wafer Coating Thickness Measurement Using 3D Profilometry

Wafer Coating Thickness Measurement is critical. Silicon wafers are widely used in the making of integrated circuits and other micro devices used in a vast number of industries. A constant demand for thinner and smoother wafers and wafer coatings makes the Nanovea 3D non-contact Profilometer a great tool to quantify coating thickness and roughness of just about any surface. The measurements in this article were taken from a coated wafer sample in order to demonstrate the capabilities of our 3D Non-Contact Profilometer.

The Worlds First Dual Load Controlled Tribometer

Irvine CA, February 28, 2018 – The Nanovea T2000 is the worlds first dual load controlled Tribometer providing vertical force oscillation at frequencies up to 150Hz. It combines advanced pneumatic technology with a state of the art linear electromagnetic stage to provide controlled loading from 1mN to 2000N during rotative and linear testing. Pneumatic is used from 5 to 2000N offering multiple advantages compared with age old spring/motor technologies used on other systems. With spring/motor technologies, the load sensor is typically placed behind the spring. This means that it is not measuring the actual variation of load applied on the surface during the test. The T2000 measures the load by a direct connection between the ball holder and the actual load cell. This ensures that the load measured is actually the load applied on the surface. The linear electromagnetic loading system of the T2000 can apply a vertical force of 0.2 to 20N at frequencies up to 150Hz. As an example, the normal load can be increased from 0 to100N with the pneumatic technology and then the linear motor can vary the load from 90 to 110N and up to 150 times per second. This gives the unique capability of superposing a control fatigue or vibration level to the main constant force applied by the pneumatic system. This electromagnetic linear stage can also apply directly very low loads from 1mN to 5N to complete the full range.

Now the World’s Leading Micro Mechanical Testing

Irvine CA, January 31, 2018 – Now the world’s leading micro mechanical testing. Automatic, accurate and fast hardness and elastic modulus results obtained from depth versus load data are truly a giant leap compared to traditional hardness testers. This past century technology was based on visual inspection when accurate depth sensors were not available. Therefore, today there is absolutely no advantage with using outdated traditional hardness testers. The Nanovea CB500 with Micro Module is faster, easier, more accurate particularly at low loads and more repeatable. Testing can be performed on any material including very elastic material or on surfaces where identifying the indent is challenging. Not only providing hardness and elastic modulus but also a wide range of testing such as creep, stress-strain curves, yield strength, fatigue, fracture toughness, scratch and marring resistance, plastic/elastic deformation, wear rate and friction coefficient.

Precision Machined Part Inspection With 3D Profilometry

Precision machined parts manufacturing calls for stringent inspection to ensure product quality and repeatable production standards. The 3D surface inspection of the part compared to CAD model is essential to verify part tolerance and machine quality. Moreover, during the service time, wear and tear of the parts may create surface defects such as scratches, dents and cracks. The part needs to be replaced when the deviation from the required specification is over the tolerance limit. Unlike a touch probe technique, the Nanovea ST400 Profilometer performs 3D surface measurement without touching, making it possible to precisely scan parts with a complex shape at a high speed.

Mechanical Properties of Hydrogel using Nanoindentation

In this application, the Nanovea Mechanical Tester, in Nanoindentation mode, is used to study the hardness, elastic modulus and creep mechanical properties of a Hydrogel sample. In this case a sample of Hydrogel can simply be placed on a glass slide due to the softness and low load being used to test; testing could also be preformed while in liquid. For this soft material a 3mm spherical tip will be used. This is to give good information on the Hydrogel and not on surface properties that might be different. This can be studied using a shaper Berkovich tip.
