The Testing Times

An established contract manufacturer of high grade materials, state-of-the-art machinery and innovative team-oriented services have recently upgraded their quality testing capabilities with a new Tinius Olsen 5ST, 5kN testing machine. The company deliver everything from spinal implants, pedicle screw systems, implant-grade PEEK spacers and other medical devices.  Of particular interest for their quality program are their implant-grade PEEK spacers. PEEK, short for polyether ether ketone, is a semicrystalline thermoplastic polymer, with excellent mechanical and chemical resistance properties that are retained to high temperatures.  This colorless organic polymer has various engineering applications, as well as being considered an advanced biomaterial for the use in medical implants. These are commonly known as PEEK implants and include minimally invasive spinal, lumbar and thoracic implants. It is also used with a high-resolution magnetic resonance imaging (MRI), for creating a partial

Strain Rate control of a tensile test Perfect Tensile strain Rate control with a Tinius Olsen using a model AEX automatic extensometer and Horizon test software control at a Chinese Aircraft manufacturer. Strain rate1.5%/min. as per ISO 6892 beautiful… We all know strain rate control is required for strain sensitive materials especially when it comes to composites, but it increasingly has a place in general metals testing because using strain rate control lowers the measurement of uncertainty when comparing test results from different models and types of testing machines and gauge length marking techniques.
