Metals impact testing INSTRON, a provider of testing equipment designed to evaluate mechanical properties of materials and components, has released the MPX series of motorised pendulum impact testers that are used in metal impact testing to Charpy and Izod standards. The MPX series offers a range of testing capabilities from 300 to 900 joules and it comes standard with Fracta™ software, which allows for reliable data acquisition and reporting of absorbed energy. If more advanced impact analysis and reporting is needed, upgrading to Impulse™ data acquisition software and instrumentation will allow for direct measurement of impact force and striker velocity. while conforming to the international standards for non-ambient testing. The feature fully complies with NIST 5 second guidelines, specifiying the time it should take for the specimen to leave the temperature conditioner and for the test to be complete. On the MPX, interchangeable hammer weights allow for quick and simple adjustment of the impact energy, removing the need for the time-consuming process of changing hammer shafts. The MPX features an integrated guard and safety control system that meets the stringent requirements for the European CE mark and for ISO 13849. The operator is protected at all times during machine operation.

The MPX is designed with an automatic test start as soon as the door closes, allowing for rapid testing and improving throughput

pipes up to 114mm is robust with wide vertical amplitude. The vertical shift option for the slide allows the use of a single slide for the different bending levels, eliminating the collision problem that occurs in case of large diameter differences in the tooling. The compact bending head moves only in X-direction, sliding on pairs of recirculating roller trolleys.

The 955LE is a fully electric bending machine for steel pipes up to 55mm, with right or left reconfigurable bending. It integrates the characteristics of the 942LE/XE and 980LE for what the company believes to be the best solutions of each model. It has the ability to accommodate numerous bending levels and to ensure multi-level bending with variable radius in the automatic cycle. The 955LE can bend both right and left through a rapid reconfiguration. The fully electric 980HE bending machine for steel pipes up to 80mm is an evolution of the 980LE, and was designed to enhance the capacity to accommodate several bending levels,

TO coincide with the rebranding of its corporate image, Crippa launched five new machines during the Tube Düsseldorf exhibition: four bending machines and one forming machine. The company also has two new systems: BrainBox, for monitoring production; and Easygauge, a system for dimensional measuring through images. The measurement is instantaneous, reducing the time required by traditional techniques. Thesoftwarenamed ‘U.I.I.’, completely produced by Crippa, provides a man- machine interface that simplifies the job of the user. The new machine solutions from Crippa are detailed below. The SMALL2R, an evolution of the SMALL1 series, is a machine for right and left cycle bending of aluminium pipes up to 20mm in reverse configuration. It is also available in a linear version. The main C axis drive is placed directly behind the bending level. The locking clamp is made through a toggle-actuated electric system, while the pressure-die is a CNC axis with rack and pinion. The head moves with the typical cross motion and is also driven by rack and pinion.
