Latest News from Hegewald & Peschke

Hegewald & Peschke Meß- und Prüftechnik GmbH has successfully modernised seven Zwick universal testing machines at Alcan Packaging Singen, which is a distributor of high-quality processed aluminium-based packaging materials. The electromechanic systems with capacities of 2 kN and 5 kN got new drives and a modern digital controller including power amplifiers.
In the course of modernisation work, long-lasting components should be systematically retained. To meet this goal, the Zwick load cells and long distance extensometers were equipped with new electronics. Consequently, it is now possible to control the extensometers reliably and safely with the testing software LabMaster, which has been developed and distributed by Hegewald & Peschke GmbH. At the same time, Alcan Packaging Singen is offered a cost-saving and future-oriented alternative to the purchase of new machines.
The modernisation work done at Alcan Packaging Singen is only one example of the manufacturer-independent work done by Hegewald & Peschke GmbH. Thereby, the focus is set on the selective exchange of single components. Long-lasting components are being kept deliberately, while others are updated to state-of-the-art technology. Modernisations of testing machines on site allow the measuring and testing technology experts to offer an economical and high-quality alternative to buying a new testing machine. Also, Hegewald und Peschke ensures the supply with replacement parts.

With the opening of a new branch office in Ulm Hegewald & Peschke Meß- und Prüftechnik GmbH expands its presence consistently. With immediate effect, companies from Baden-Württemberg, Southern Bavaria, Austria, and Switzerland will have a professional contact for all their questions concerning measurement and testing technology. Furthermore, the new office, which is managed by Udo Jeske (53), is the basis for the strategic establishment of the ‘Service Center South‘ of Hegewald & Peschke Meß- und Prüftechnik GmbH.
Firstly, there are going to be three colleagues in the office in Ulm, who are responsible for taking care of local customers. That means, e.g., that highly-qualified technicians do installations and calibrations of testing machines. Additionally, they are offering special orientation, maintenance services, and training programmes. Technical problems can be solved quickly and reliably on the premises. Furthermore, there is a spezial mechanic-technological laboratory for the solution of customer-specific testing problems at the office.

The team of Hegewald & Peschke GmbH thanks all visitors of our fair stand at the Control 2008 (www.control-messe.de). This year, the most important meeting of the quality assurance sector took place in Stuttgart for the first time. This event was reason enough to present Hegewald & Peschke GmbH with a new stand concept: Many innovations could be seen on an exhibition space of 60 sqm. This includes for example the contact-free laser extensometer for universal testing machines and the new universal hardness tester Omnitest with automatic imprint measurement. Furthermore, the complete range of universal testing machines and hardness testers was demonstrated at the stand.
“The Control 2008 was a big success for our company,“ comments Volker Peschke, business manager of the Saxon specialist for measurement and testing technology. “The large number of visitors at our fair stand already foreshadowed what was later confirmed: During the Control 2008 fair Hegewald & Peschke GmbH was able to win a large number of new customers, especially from Southern Germany. These customers can be looked after by our new branch office in Ulm.
The success at the Control 2008 is again an incentive for us to continue focusing on high-quality products, reliable customer service and an attractive price-performance ratio.“

Contact-free optical extension measuring methods become more and more important in material testing. They are primarily adopted when mechanically sensitive materials or temperature conditioning devices are used during the measurement. The so-called laser speckle method (laser speckle extensometer) achieves very good results in that field. It has been especcially redeveloped by Hegewald & Peschke GmbH for contactless extension and deformation measurement. The operating principle of this method is based on the analysis of speckle patterns which result from the reflection of a coherent laser beam off the surface of the specimens. One or several cameras record the pattern and analyse it reliably with the help of analysis of correlation. The unique pattern is used as imaginery gauge mark. During the test the distances within the pattern are measured and thus the extension can be calculated.

In collaboration with the DGZFP we will continue our successful courses on mobile hardness testing in 2008. In the three day seminars participants will learn about the theoretical and practical basics of mobile hardness testing. In practical exercises with different mobile devices they will also learn about specific testing difficulties. The course is completed with an exam and certificate. You can find dates for the courses on our homepage under “News / Fair dates”.

Hegewald & Peschke GmbH designed a specific, motor-driven bending machine for technological wire testing according to DIN 51211. The machine can be used for bending tests according to DIN 51211 on wires with diameters between 2.0 – 9.0mm (max. tensile strength 2,000MPa).
Exchangeable folding rollers allow for defined deforming depending on the wire’s diameter. The bending arm is driven by a servo drive. The test length can be set according to the used standards. The number of bends until the specimen breaks is counted by a cycle counter.
