Lübeck, July 1, 2019. Rosswag Engineering has announced the acquisition of its third selective laser melting system from SLM Solutions. The third SLM^®280 machine delivered to their facility in Pfinztal, Germany, expands their production and development capabilities with the metal additive manufacturing technology.

A division of Rosswag GmbH, one of the world’s leading providers of open die forged products with nearly 120 years of experience in the manufacturing of 400 different metal alloys, the company has built decades of know-how in material science and combines its production expertise on SLM^® machines with a complete in-house process chain from metal powder production, design, process simulation, and printing to CNC post-processing and heat treatment as well as metallurgical testing and quality control.

As a strategic partner of SLM Solutions in the advancement of the selective laser melting technology, Rosswag Engineering also qualifies new alloy powders and parameters by combining the capabilities of their simulation software package, powder atomizer and three SLM^®280 machines. With the ability to quickly produce special metal powders, simulate build results, print tests using SLM Solutions material development module, then post-process and inspect builds in-house, the time to market cycle for new materials is reduced from months to weeks.

Using the Material Development Module from SLM Solutions, Rosswag duplicates part positioning and uses rule-based parameter variation for an automated and systematic analysis of parameter sets. After completing the qualification process, comprehensive data for production, including metal powder characteristics, process parameters, mechanical values and chemical and metallurgical material properties are available.

“At Rosswag Engineering our goal isn’t only to provide our customers with quality products built on metal additive manufacturing machines, rather to help the technology gain acceptance and expand,” stated Gregor Graf, Head of Engineering at Rosswag. “By adding a third selective laser melting system we are able to increase our production capacities and gain more flexibility for demanding material and part qualification processes.”

Hendrik Schonefeld, Head of Sales EMEA at SLM Solutions said, “Our partnership with Rosswag allows us to help customers develop small-batch and exotic alloys to meet their unique needs. SLM Solutions is focused on production applications, and our machines reflect this, however many customers need quick parameter development to prove their process before they get to that step, and the experts at Rosswag allow us to meet their needs as well, creating a full-service selective laser melting partnership for all types of customers.”

So successful is the process developed by the experts at Rosswag that the company was recently the first company certified as metal powder manufacturer by TÜV SÜD Industrie Service GmbH through their audit based on the AD 2000 Code for pressure equipment and the European Pressure Equipment Directive (PED).

Automation, networking and robotics are rapidly gaining ground in metalworking – and in storage and sawing technology. Storage systems and sawing machines are increasingly being integrated into a uniformly controlled material flow in which all processes between incoming and outgoing goods are fully automated – from the storage of the long goods raw material to the dispatch of the palletized finished parts. This enables users to make their production processes much more flexible and efficient, improve working conditions and significantly reduce operating costs. At Kasto, these topics have long since ceased to be visions of the future.

Whether they are in the steel trade, the automotive and supplier industry or in mechanical and plant engineering, metalworking companies across all industries have been facing increasing demands for years. Customers expect ever greater production flexibility, from batch size one to mass production. The variety of materials and sizes is steadily increasing. At the same time, quality standards are rising and there is continuous pressure to cut costs. To hold their own against international competitors, companies need versatile and efficient solutions for a wide variety of production tasks.

Kasto offers efficient raw material management through fully automated storage systems

More and more users are relying on the automation and intelligent networking of individual workflows in production and logistics. This begins with the storage of the delivered raw material – instead of the previously widespread floor or cantilever storage, companies are increasingly relying on fully automatic long goods storage systems. These automated software-controlled systems have completely convinced users with their significantly higher storage density, fast access times and maximum stock transparency.

Cassettes are usually used as load handling devices for the storage of long goods. A storage and retrieval machine automatically transports these to one or more transfer stations in line with the “goods to the next process” principle. These can be designed differently for the respective requirements, as fixed stations, for example, or in movable form as longitudinal or transverse transfer carriages. Automatic storage and retrieval is not only much faster than by hand, it also protects employees from accidents and injuries as the heavy and bulky goods do not have to be moved manually. Orders are processed at the push of a button via the warehouse control system – or directly via a higher-level ERP system to which the control system is connected via an interface.

Optimized added value thanks to the linking of the storage systems with fully automatic sawing machines

The sawing of the articles removed from storage is often the first step in processing or manufacturing. Here too, all processes are increasingly organized without any human participation. The modern Kasto sawing machines can be seamlessly connected to the raw material warehouse by means of manipulators and conveyor technology and are supplied with the required materials. Depending on how it is equipped, the sawing machine can also run by itself. Material is fed to it automatically, and an intelligent machine control system sets all parameters, such as cutting length and cutting speed, based on the job data. State-of-the-art production saws can thus carry out a variety of jobs in succession with different materials and diameters, and operate autonomously for long periods.

High performance and perfection thanks to the integration of intelligent robots

Industrial robots also have considerable potential when it comes to handling and processing finished cut parts. Depending on the production cycle, for example they can remove the sawn parts from the machine at maximum speed, so employees no longer have to carry out this repetitive task. In addition, the robots can be used with the appropriate tools to add value for deburring, chamfering, marking, centering, cleaning or measuring and testing the workpieces. The sections can be weighed, sorted by size or order, and stacked on pallets or in tightly packed containers. For complex processes with different work steps, combinations of several robots and clamping devices can also be realized with Kasto systems. Further connection to driverless transport systems (AGVs) is also common practice nowadays.

Downstream processes are relatively easy to automate with volume saws that process only a few different component geometries. The situation is somewhat different with individualized job saws, however; they have to flexibly process numerous materials and dimensions, and the greater the diversity, the more challenging it is to fully handle all the tasks. For example, the optimal selection of robot tools is important, because the robot should be able to manipulate all the objects to be handled with as few aids as possible. This reduces procurement costs, minimizes idle times and increases productivity. Users can choose from mechanical, magnetic or vacuum-driven grippers. The grippers should be as compact as possible to give the robot easy access to the cut parts. Kasto supports users in defining the optimal tools for the upcoming tasks. In regular operation, the robot then independently decides which tool is best suited for the current task. The decision criteria may be the accessibility of the workpiece or the optimization of the stacking pattern.

Industry 4.0 has long since arrived in the world of storage and sawing technology

With the right components, storage, sawing, automation and robotics technologies can be combined to form decentralized and highly integrated systems that are seamlessly integrated into one continuous material flow. The manufacturer Kasto realizes combined storage-sawing-robot systems for its customers, in which all storage, handling, sawing, marking, palletizing and bundling processes run fully automatically, from the storage of the raw materials to the picking of the sections. The big advantage here is that the entire system functions with a uniform control software, which can be connected to existing Erp systems such as Sap with only one interface. This significantly increases transparency and efficiency. With additional production machines, such as for turning or milling, the storage, sawing and robotic systems can be linked to form a fully digitalized and automatic production system that organizes itself decentrally and independently, in line with industry 4.0.

Automation and robotic support offer significant advantages for the user, who can significantly increase productivity with less personnel, since many processes are not only unmanned, but also run much faster. It is easier to compensate for staff absences due to illness, and production simply continues even during breaks or after shifts. The result is lower personnel costs and a high degree of flexibility in terms of capacity utilization. For example, companies can process order peaks much better and drastically reduce non-productive times. This also quickly becomes noticeable from a profitability point of view.

Users and their customers benefit equally

Working conditions are also improved by the automated technology, because employees are relieved of heavy, tiring and monotonous work, reducing the risk of accidents and injuries. The quality of the sawn sections is also enhanced, because the robot processes all the parts uniformly and precisely, sorts them reliably and stacks them cleanly. This ultimately benefits not only the plant operators, but also their customers.

Manufacturers of steel tubes and bars are increasingly confronted with the fact that their products must meet higher quality requirements. Tight specifications for precise outer diameters are established in the market for many years, but demands for product straightness are now increasing.

In the past, a few off-line samples were used to analyze the entire production. Important process information was lost and a complete quality control across the entire production could not be guaranteed.

With the new Bendcheck system from Zumbach, straightness, diameter and ovality can be measured directly in the production process. With an extension of the number of measuring points, head and tail bend of the product can be determined in addition to the straightness. Each pipe or bar is therefore completely recorded, measured and logged. Deviations are indicated in real time, so that the production process can be optimized quickly and profitably and unsatisfactory products can be sorted.

A customer-friendly display and control unit visualizes all important and relevant data at a glance. Measured values, statistics, trend charts and process data can be displayed clearly and conveniently. Thus, the new Bendcheck system offers a complete measuring solution for the increasing demands of the market.

As part of the fourth industrial revolution, Industry 4.0; in-line measuring systems are taking over increasingly more important roles. Also in this area the new Bendcheck system can fulfill the high expectations. The seamless acquisition and processing of measured data enables exchange with higher-level systems via communication protocols such as OPC UA and therefore making an important contribution to the digitalization of production processes.

With the Bendcheck system from Zumbach an industrial solution is now available which records and makes available all important data of a modern production.

Frickenhausen/Stuttgart, 3 June 2019 – The 14^th Blechexpo, in combination with the 7^th Schweisstec, will welcome exhibitors and expert visitors to Stuttgart with world-class process competence covering all aspects of sheet metal, pipe and profile processing from the 5^th through the 8^th of November, 2019. The two complementarity industry events provide expert visitors with comprehensive product and service offerings dealing with all facets of thermal and mechanical processing, as well as welding, joining and fastening technology.

Floor Space, Exhibitors, Internationalism: New Dimensions in Sight

The Blechexpo-Schweisstec trade fair duo takes place once every two years. Roughly five months before the event opens its doors, project manager Georg Knauer from trade fair promoters P. E. Schall GmbH & Co. KG is already registering more exhibitors, more exhibition floor space and higher levels of internationalism for Blechexpo and Schweisstec than two years ago. An increase amounting to more than 150 primary exhibitors and a 20% rise in exhibition floor space as opposed to the corresponding timespan in 2017 has already been verified, and it’s becoming apparent that the results from the record-breaking year in 2017 will be topped. A total of roughly 1500 exhibitors will set the tone at Blechexpo-Schweisstec in nine exhibition halls in Stuttgart. Bookings and reservations from foreign countries near and far have even doubled as compared with 2017 – a full year before the trade fair opens, the figures from 2017 for technology companies from Italy, China, Turkey and Spain had already been exceeded. The reason for this boom is the strictly practice-oriented concept of the trade fair duo: Blechexpo-Schweisstec covers all relevant issues and trends with relevance for the digitalised, automated world of sheet metal and metals processing.

Sheet Metal Still Dominates as a Structural Material in Machinery and Equipment Manufacturing

As a structural material – along with pipe and profile materials – sheet metal has evolved into a common alternative to conventional cast iron, steel and plastic constructions. FEM optimised lightweight design and modular component systems characterise the image of modern, material, weight and cost-saving vehicle, machinery and equipment manufacturing – all the

more reason to focus on precision cutting, stamping and forming of steel, aluminium and non-ferrous sheet metal at Blechexpo and Schweisstec.

Expert visitors are presented with solutions and systems covering all aspects of pre-processing and final processing, module assembly and surface finishing for sensitive, visible components. The issues of lightweight design, design engineering solutions, handling, quality assurance, automation and digitalisation in sheet metal processing and joining technology are also dealt with extensively.
