EuroBLECH Bulletin

News from the Organisers

Season's Greetings from the EuroBLECH team

With 2015 coming to an end, the sheet metal working industry is looking back at another busy year year. Once again, the sector has proven itself to be economically stable on a national and international level, standing out particularly for its extraordinary engagement in research and development. Integrated production and more efficient manufacturing and processing methods are transforming the sector. Major corporations as well as medium- and small-sized companies are facing the global challenges of the sheet metal working industry and have taken on active parts in the modernisation process.

The year 2016, the year of EuroBLECH, is again dedicated to innovation and technological progress. In anticipation of the coming year, we are looking forward to welcoming you at EuroBLECH in Hanover in October 2016.

The entire EuroBLECH team of Mack Brooks Exhibitions wishes the EuroBLECH community happy holidays and a successful year 2016.

For Exhibitors

Hall allocation phase for 2016 has started

Pre-booking for stands as well as the hall allocation phase for EuroBLECH 2016 have started. Nearly 1,200 companies have already secured their stand space on a total net exhibition space of 90,000 square metres. The exhibition will again occupy eight halls at the Hanover Exhibition Grounds: halls 11, 12, 13, 14, 15, 16, 17 and 27.

EuroBLECH 2016 covers the entire sheet metal working technology chain: Sheet metal, semi-finished and finished products, handling, separation, forming, flexible sheet metal working, tube/section working, processing of hybrid structures, joining/welding, surface technology, tool technology, machine elements, process control and quality assurance, CAD/CAM/CIM applications, factory equipment, environment protection, recycling and R&D.

Floor space requirements can still be provisionally reserved on the exhibition website.

Industry and Technology News

New fiber cutting technology from Bystronic

The fundamentally redesigned machine concept ByStar Fiber by Bystronic is expanding the range of applications for cutting technology. The innovative fiber laser was designed to cut through thin sheet metal at a particularly high speed, and also to deliver an outstanding cutting performance in the thick sheet metal range.

The development of the new fiber laser is Bystronic’s reaction to the increasing demand for all-round solutions which require low operating costs and low maintenance. The fiber laser is aimed at manufacturers who seek to cut their entire range of orders with a cutting quality that remains consistently high: from stainless steel, aluminium and construction steel to non-ferrous metals such as copper and brass.

With the new technology, Bystronic focuses on high cutting dynamics, seamlessly integrated automation solutions, intelligent sensor technology and integration into modern software systems, in order to lead to efficient and interconnected manufacturing.

AP&T: Outstanding knowledge in press hardening

AP&T has received the University of Kassel’s new distinction, the Certificate of PHS Team Excellence, for outstanding knowledge in press hardening. AP&T’s Future Forming Seminar in Shanghai was focusing on the question of how the car industry could take advantage of new materials and forming methods to reduce vehicle weight, and thus to positively influence fuel consumption and climate impact.

Lower fuel consumption and reduced carbon dioxide emissions are the main driving forces behind the automobile industry’s interest in lighter materials and weight-saving forming methods. According to Dr. Christian Koroschetz from AP&T’s R&D centre, press hardening technology has brought about a revolution in automobile manufacturing, yielding significant potential for continued development. AP&T is currently investing in employee training in press hardening in the U.S., Asia and Europe.

Whether the future of automobile manufacturing lies in press-hardened steel, composite materials, hot-formed aluminium, or perhaps magnesium, remains to be seen. It is certain, however, that development is moving from using conventional cold-formed steel to using a combination of different materials. There is a rising interest in new light-weight opportunities of materials such as carbon fibre.

SSAB launches tailor-made high-strength steels for the automotive industry

SSAB, manufacturer of high-strength wear and structural steel, is launching new steel grades. This is creating new potential for the automotive industry. According to José Puente Cabrero, Portfolio manager of automotive products, the company is planning to release two new hot-rolled advanced high-strength steel grades within the next year. They are being designed especially for chassis applications, exceeding 800 and 1,000 MPa in tensile strength, and offering a unique combination of properties for maximized hole expansion and edge ductility.

Aside from that, SSAB is looking to introduce new cold-rolled martensitic steels with improved flatness. The latest Docol martensitic steels for cold-formed applications, with a tensile strength above 1,700 MPa, are used within the design of upcoming car models.

With higher tensile strength affecting the ductility of advanced high-strength steel products, José Puente Cabrero claims that the company is now going to introduce new press-hardening steels which are optimised to reach tensile strengths above 2,000 MPa, but with retained good ductility. Another new product, the new structural steel ‘Strenx’, was launched earlier this year, a light-weight material of strength, excellent weldability and toughness.

Other companies, like TBEI, a leading truck manufacturer in the U.S., use SSABs’ input to explore the potential of steel for automotive manufacturing: The company developed a light-weight dump body made from steel which is stronger and less expensive than a comparable aluminium unit.

New focus on tool engineering for transfluid’s tube moulding machines

In the development of moulding technologies, versatility is a common challenge, depending on the sector and application of a tube. The company transfluid Maschinenbau GmbH focuses on the tool in particular, rather than the machine, in order to find an appropriate solution and ensure the right design of every product.

Given the diverging, individual requirements of manufacturers, the machine and the process can vary a lot. When it comes to upsetting technology, varied capacities of 98kN, 147kN or 196kN could be required from transfluid, as managing director Stefanie Flaeper states. Alternative opportunities would be the roller technology, which facilitates tooling-independent moulding with only one tool, or even combination machines which display axial and roller moulding in a tube clamping.

The tools applied in the process are crucial for the moulding of every product. Therefore, the company includes feasibility studies and, if necessary, sample production and prototyping, in their tool development.

Tool design remains a relevant topic in particular for axial tube moulding. For instance, transfluid often inserts an intermediate clamping unit in hose connections, as long as the cycle time allows for it. This way, the entire geometry can be supported from the inside to prevent tubes from bending inwards at sensitive locations.

For the production of multiple upsets that cannot be manufactured in the above-mentioned manner, single-tier ‘sliding split moulds’, equipped with an internally controlled pneumatic guard lock, are applied. This prevents scratches on the geometry when clamping claws are opened after the moulding process, and the position of the sliding element is visible at all times.

A special technical feature are the upsetting tools: They open up when the moulding tier moves back and forth. This way, there is no contact between material and tool, thus avoiding any cold welding and damage to the surface of the material. Even multiple beading along with an intermediate clamping fixture can be produced with this technique.

Due to the progressive development of various tools, transfluid can further promote their ‘t form’ tube moulding machines in terms of efficiency and profitability.
