Review: STESSA 2018, Christchurch (NZ)

By WP on Mar 07, 2018

The 9th International STESSA Conference on the Behaviour of Steel Structures in Seismic Areas took place from February 17 to 19 in Christchurch (New Zealand). This conference, which is triennially held, is organized by the Steel Construction New Zealand Incorporated (SCNZ) in cooperation with the University of Auckland, the University of Canterbury and the University of Naples. Like the previous STESSA Conferences, the University of Canterbury was selected to host this event.

Chemical Processes for the Surface Treatment of Components (2)

By WP on Feb 21, 2018

This is part 3 of our series on surface treatments of components. Due to the great number of different chemical processes, we have split them up and explored these processes in the previous article:

  • Chromate conversion coating
  • Phosphating
  • Galvanizing
  • Plating
  • Black oxide.

This blog article covers the remaining chemical processes commonly applied for the treatment of component surfaces.

Chemical Processes for the Surface Treatment of Components (1)

By Lars Jahnel on Feb 07, 2018

In our first blog article we presented the most common mechanical processes for the treatment of component surfaces. In this second part, we address the most frequently used methods of chemical surface treatments. The decision as to which of the following treatments should be applied is predominantly influenced by design points of view, technical aspects and the intended appearance of the product.

Mechanical Processes for the Surface Treatment of Components

By Lars Jahnel on Jan 24, 2018

The surface finish of components used in the field of mechanical engineering as well as of other products is not only determined from a design point of view, but is mainly defined by the technical aspects. From the onset, the specification of the requirements regarding the condition of component surfaces, e.g. of a shaft coupling, often has far-reaching consequences on the product development process, the resulting costs and, eventually, on the succes of the final product.

8 Healthy Day-to-Day Work Tips for Engineers

By Hannah Döttling on Jan 10, 2018

New year – new luck! This also means: a new attempt at keeping the good resolutions we keep on setting for ourselves at the beginning of a new year. We admit: we usually revert quickly to old habits. But, aren’t we annoyed with ourselves? So, why don’t you put into action one very important resolution commonly with us? We’ll show you how you can make your workday healthier with only a few tricks – this will not only help you work more effective and motivated, but in the long run, your health will also benefit from this.

Last Minute Present Ideas for Engineers

By Hannah Döttling on Dec 20, 2017

The Christmas season – the time of rest and reflection? Well… instead of love, harmony, warmth and a sense of well-being, many of us actually associate the pre-Christmas period with stress, deadlines and overtime. A pile of projects heaped up on our desk which, ideally, should be completed before the holidays. In our private life, Christmas parties, visits to or from relatives and preparations for Christmas dinner make schedules even busier.

But, let’s be honest: the greatest cause of stress comes from our desperate search for suitable presents. After all, we would like to get something "special" for everyone.

If this sentence makes you nervous – don’t panic! We are going to show you how you can still please your loved ones with only four days before Christmas, in spite of your long to-do list.

The ATEX Directive - Example of its Application in Practice

By Norbert Telaar on Dec 06, 2017

The term ATEX is derived from the French denomination "Atmosphères Explosibles" (explosive atmospheres): The ATEX Standard comprises the Equipment Directive 2014/34/EU as well as the Workplace Directive 1999/92/EC. In a previous article about the ATEX Directive we put more emphasis on general issues and theory. In this article we use the example of a flexible claw coupling to explain in more detail how this standard is implemented in practice.

Coupling and Locking Assembly Options for Warehouse Automation Systems

By Ross Rivard on Nov 22, 2017

When it comes to automated warehouses, precision is key. Hundreds of shuttles and miles of conveyors must all work together to ensure products are transported successfully to their designated location for storage or delivery. Of all the components that play a role in the precision of these systems, do not forget about Couplings and Locking Devices – both of which are widely used in this application.

The Development of Locking Assemblies

By WP on Nov 08, 2017

Today, Locking Assemblies and Shrink Disks are standardized elements which provide a frictional connection between a shaft and a hub. They are not only capable of reliably transmitting torque, but of axial and transverse forces as well as bending moments, too. Oskar Peter is the father of the Locking Assembly. He recognized back in the 50`s that a locking assembly, in contrast to a key, is able to transmit considerably higher torques, thus allowing the engineering of much thinner and shorter shafts.

Trade Fair Review: Exposibram 2017, Belo Horizonte

By WP on Oct 25, 2017

The 17th edition of the biannually held EXPOSIBRAM took place from September 18th to 21st in Belo Horizonte (MG), Brazil. With a floorspace of 12.000 m², this exhibition is considered one of the greatest mining events in South America, gathering representives of government authorities, contractors as well as private organizations in the same place. EXPOSIBRAM also hosts the Brazilian Mining Congress, which is organized by IBRAM (Brazilian Mining Association).
