The Testing Times

The Tinius Olsen Testing Machine Company has been providing materials testing systems to the manufacturing industry for over 135 years, pulling, pushing, squeezing, bursting and twisting packaging materials, enclosures, and packaging devices to accurately quantify strength, performance and quality. Using the data from a Tinius Olsen testing system QC Mangers and their teams are able to monitor, prove and maintain the quality of their products, be it tapes, adhesives, plastic film, metal foil, bottles, enclosures, bags and devices. The key business needs; Efficiency, immediate feedback of test results to the production team and traceability are all met by the new Tinius Olsen automated materials testing platform. The item to be tested is passed automatically into the Testing Cell, then handled by a six axis robot, it can be dimensional checked, loaded into the tensile testing machine and tested. Immediately post-test the Pass/Fail status is reported, and the robot sorts ...

Tinius Olsen's  2D strain mapping option software is available for existing and new video extensometer installations for use with the Standard and Advanced software products. 2D strain mapping is used to give a graphical representation of the strain amounts varying across a specimen during a test, illustrating the non-uniform strain taking place.  Pictured strain map of a tensile specimen at break Typically users take these pictures and include them in report analysis and conclusions alongside standard results and graphs adding to the data and overall analysis of a material or components performance under load. Check out this clip of a flexural specimen under test and strain mapped;  

I often get asked “Why do your large Brinell hardness testers not have a clamp option” The answer begins with understanding why old technology Brinell testers had and required a clamp feature. They were dead weight machines i.e. the load (in the case of regular Brinell 3000kg) was applied using actual physical weights hanging inside the machine. If a work piece or component was not clamped it could move as the weight was applied thus resulting in an indentation in the metal which could be less than the true size due to the movement. So A clamp was used to pre clamp the work piece or component thus stopping it from moving as the load was applied ensuring a true sized indentation. However a modern closed loop Brinell tester like the Tinius Olsen models FH-009, FH-008, FH-012 do not use dead weights, this means clamping of the work piece is not required. This is because the closed loop system sampling and applying the 3000kg force ensures, very accurately, that the tester keeps ...

Tinius Olsen’s New model FH-6 Micro Vickers, Vickers and Micro Brinell hardness testing capability. It’s an automatic Vickers hardness tester using the turret technology to hold up to two different indenters and four objectives which automatically selected and utilized when test is started. This technology can help your business make money by increasing the efficiency of your Vickers tests. By using automation it cuts typical testing time in half, more for large pattern tests. And if the pattern tests per sample need to change, for example when testing around weld sites, the time saving is huge. Simply take the stored existing pattern, use it as a template and drag the intended indent points using the mouse or touch screen as required. This tester does not save you money, it makes you money. FH-6 Material testing machine is capable of performing physical strength test in hardness on raw materials such as metal, plastics, large parts and small precision parts, it is a very ...

These days angioplasty, is an endovascular procedure to widen narrowed or obstructed arteries or veins, is almost considered a routine procedure, yet the technology behind it is exacting and subject to rigorous quality and performance control. In this procedure a n empty, collapsed balloon, known as a balloon catheter, is passed over a wire into the narrowed locations and then inflated to a fixed size. The balloon forces expansion of the narrowing within the artery or vein and the surrounding muscular wall, opening up the blood vessel for improved flow, and the balloon is then deflated and withdrawn. A stent may, or may not, be inserted at the time of ballooning to ensure the vessel remains open. Not only are the stents themselves, and the wire used in their construction, tested for tensile strength, compressive strength and stiffness properties, so too are the balloon catheters used to deliver the stent into the body. In recent times, more attention is being paid to...
