In-house Page 7 New standards in quality management In practice GRÜNES HERZ quickens heartbeat Page 8 Editorial Trends+ Markets By Friedrich Herdan, President Meet the challenge Times really change quickly: while the German industry was glad to see a clear improvement in orders received at the end of the summer, meanwhile disillusionment has returned. Even more so following the first decisions made by the new Federal Government. While we are well aware of the fact that the realisation of these decisions will again result in an increase in ancillary costs in Germany, we consider it futile to discuss whether they are adequate, useful or even unavoidable. They exist – and the companies, as well as their employees, will have to live with them. The challenge inherent in this situation can be accentuated by one single question: How can we remain competitive internationally in spite of the increasing load of taxes and levies? The answer is as simple in theory as it is difficult in practical realisation: We have to become even more efficient in all sectors – and at the same time we have to be more creative than ever before in developing new, innovative and unique products and services. Without disregarding the dimensions of this task, I am optimistic, as the people and companies in Germany have always excelled in overcoming difficult situations handson. In which way LASCO, as a supplier of technologies to its customers, meets the challenge, is reflected by a series of articles in this edition of UpGrade. With my best wishes to you and your employees for a beneficial reading, a merry Christmas and a good start into the new year. 2 UPGRADE Progressive technology. Having completed the conversion to HICAD in design software, LASCO now possesses a uniform 2D/3D-system (left picture). The core feature of the required migration was the conversion of the archives of about 40 000 2D-drawings including the corresponding meta data. LASCO installs 30 HiCAD-licences Change in record time Coburg. LASCO Umformtechnik GmbH has performed the conversion from a 2DCAD-system into the uniform 2D/3D-system HiCAD from the company ISD Software und Systeme GmbH within a very short period The core feature of this migration was the conversion of the existing archives of about 40 000 2Ddrawings including the corresponding meta data. A total of 30 CAD worksta- tions have been changed to HiCAD. Convincing testing phase After the start of the project in November 2001, there was an initial 90-day testing phase with four HiCAD workstations, during which 1 500 drawings were converted by the ISD as a first step and a specification for a MRP coupling was established. This testing phase was so convincing that already at that time the decision was made to install further HiCAD workstations. Another 90 days were intended for the realisation of this objective. During this time the entire existing 2D-data of 40 000 drawings including all database entries were converted. In parallel, 32 employees were trained and a network was installed. Moreover, the hardware supplied by ISD and a bootable MRP coupling were installed. Smooth conversion In retrospect Günter Hofmann, head of the design department and Prokurist (authorised signatory), states: "We have suffered no losses at all in the design department during the conversion.” Mobile communication Help to help yourself Coburg. New technologies permit mobile solutions for communication that take information and applications to the place where they are really needed: to the machine user on site. LASCO has recognised this tendency at an early stage and profited from it. Upon the request of the customers LASCO forming units have been equipped with tele-service systems for several years now. Their advantages are evident: the transfer of data about the control system and about the condition of the machine to the manufacturer Cover picture: LASCO SPR 315 at GRÜNES HERZ in Thuringia. by LASCO - December 2002 enables the latter to get a comprehensive picture and to provide useful assistance to the service personnel at site regarding maintenance, conversion and repair work. New standards in wireless communication and picture transfer permit this even in real time, i.e. directly from the expert to the technician at the machine. Mobile solutions for communication increase the availability of the production line, improve the quality of services, speed up the commissioning and provide a greater flexibility of manufacturing lines. Here, the use of standard technology assures the efficiency of these systems. On-line competence. Modern mobile communication units permit direct assistance for the maintenance personnel from the manufacturer – at site and in real time. News Stamperia di Menzago wants to grow Menzago. The mediumsized forging company Stamperia di Menzago with its seat in Menzago di Sumirago (in Central Italy) is pleased to do good business. Now, the company invests into a hydraulic LASCO double-acting hammer type HO-U 200 in order to improve the quality of its products even further and to expand its range of products. Founded in 1967, Stamperia with its 40 employees manufactures predominantly components for the automobile, motorcycle and mineral oil industry. The order is the first one for a machine placed with LASCO by Stamperia di Menzago. Special shifts in the manufacturing department Hot autumn for fitters Coburg. From September to November LASCO delivered machines having a total value of close to ten million Euro. The employees in the fitting department were faced with a proverbial "hot autumn”. They had to work special shifts to assure the timely delivery and commissioning of a total of seven forming units to Germany, Eastern Europe and overseas countries. A deep-drawing press type TZP 800 for sheetmetal forming was delivered to Paderborn and a hydraulic double-acting hammer type HO-U 630 in special design to Plettenberg. Screw presses of types SPR 315, SPR 800 and two SPP 630 were expected by customers in Thuringia and in the USA. Also a Russian customer, who had manufacturermodernised a LASCO hammer KH 100 with long merits, was able to start production on time. Heavy load. The machine seeming to be as light as a feather is by no means suitable for air freight. The SPR 315 that was loaded onto an articulated lorry in November for delivery to a customer in Thuringia weighs almost 18 tonnes. Products from Waltec Forgings in great demand Jung Boucke orders forging line New Pacemaker 16th Unit from LASCO Wallaceburg. Waltec Forgings of Wallaceburg, Ontario (Canada), is preparing to install a new LASCO SPR 1600 direct drive screw press with frequency converter. Thus, the com- pany wants to keep up with demand for its high-quality, highly engineered nonferrous forged products. The industrial group founded in 1954 is considered the leading Canadian source for forgings, machined forgings and screw machined components in a variety of non-ferrous alloys. Halver. The high-tech-forger Jung Boucke in North RhineWestphalia has ordered one more forging line from LASCO - its 16th forming unit. The company has now projected together with LASCO a forging line consisting of a hydraulic double-acting hammer HOU 250, automation equipment and a master control system for the production of valve rockers and towing hooks. The 16th LASCO machine is due for production in Halver in April 2003. At Jung Boucke GmbH & Co. already 15 LASCO double-acting hammers between 125 and 200 kJ, as well as a 1000 t forging press, are in operation. Looking back at a history of more than 100 years, the company with its more than 300 employees in two locations, as well as its 100 % subsidiary Flockenhaus at Gevelsberg, manufactures among other things towing systems, motor-, gear-, steering- and brake components, hinges, seat- and restraining systems, flanges, spring shackles, valve flaps, clamp connections and systems for the fixing of axles. Convincing solution for sheet-metal forming Most rapid start Coburg. Fully automatic manufacturing solutions developed by LASCO for the production of structural parts from sheet-metal for vehicles convince the automobile suppliers. Good stress-relief ensures longer life. The massive U-frames for LASCO forging hammers are stress-relieved. This process ensures material properties needed in view of the enormous blow forces of up to 100 MN. Recently, a renowned German supplier of the automobile industry has been honoured by the respective automobile group for the most rapid start of serial production of the products ordered by him. Since March 2001, the parts in question have been produced on a fully automatic LASCO deep-drawing press TZP 1000. The customer had decided on a co-operation with LASCO owing to the quality of project management and to the know-how. In November he installed an additional TZP 800 including LASCO automation technology (walking-beam transfer).

For a long time, the computer-aided simulation of forming processes had been disparaged by the production companies as an engineer’s toy. Meanwhile, more and more forming companies have detected the tangible advantages they get from using this innovative technology. To find the optimum forming process for the component to be manufactured more quickly and at more favourable costs – often, this is one of the keys for a decisive head start over one’s competitors. For about half a year LASCO has been using the simulation technology in customer-orientated project management. This had been preceded by an intensive testing phase with various software solutions, as well as by the co-operation with a chosen manufacturer in optimising his EDV-tools. "Based on our longstanding know-how regarding forming processes we have had an intensive exchange of views with the software supplier. Moreover, we have made suggestions to improve the functionality of the software,” explain Manfred Baudler, Dipl.Ing. (FH), head of department in the section of process technology and projecting, and his assistant Adrian Wien, Dipl.-Ing. (FH), who intensively deals with the application of simulation software to the areas of projecting and process technology. In the meantime, more than a dozen actual studies have been carried out for our customers. The results of these simulations have convinced everybody. 4 UPGRADE Magic Triangle The simulation technology is used at the beginning of the projecting phase for a forming unit. The determination of the optimum forming machine, the examination of the flow of material and the fixing of the individual stages of the process for the component to be produced form the magic triangle being the aim of such a study. Here, the focus is on the force and energy calculations when choosing the machine, on the determination of the degree of filling and of folding when examining the flow of material, and on the selection of the optimum billet and of the number and kind of preforming operations when fixing the stages. CAD and simulation software 1. Study: applications and stp for 3D applications. Moreover, all process data, such as material, component temperature, lubrication, etc. are required for a simulation. If no design data for the component and for the tools exist and can be made available by the customer, they will be established by LASCO at the CAD (2D or 3D) based on customer drawings and Pre-form 1 2.

The calculation shows that a unit having a blow energy of more than 193 kJ can perform this task by ten blows. Know-how Virtual profiling. The numeric characterisation of all properties of forming units relevant to the process is the pre-condition for fixing the optimum machine for the component to be produced during a simulation. At LASCO, all types of their own (from the left) screw presses, hydraulic presses, electric up-setters and forging hammers are covered by the software. will be converted to the respective format. Then, the model will be built up in the simulation software, the necessary parameters will be entered and the calculation will be started. ange as an example -> Flaws Testing alternatives The pre-condition for the expressiveness of the simulation are databases where the parameters relevant for the processes of the forming machines and the materials of component and tool are stored. Those "virtual profiles” stored will always have to be updated and adapted to technical progress. Finisher 1 -> No flaws! Finisher 2 Machine selection with a steering knuckle as an example (Hydraulic press) At LASCO we can perform calculations for all our own types of screw presses, hydraulic presses, hydraulic double-acting hammers and electric up-setters linked with a multitude of materials and alloys used internationally. Exact FE calculation The design data entered are first covered by a network using finite elements. Adaptive self-controlling algorithms will generate a non-uniform optimum knot density in the tetrahedron networks – in 2D (rotation symmetrical components) and 3D designs (complex, non-symmetrical components). This provides the key for an exact calculation of critical spots and for a reduction in calculation time. The preparation of the simulation process will be completed essentially by the definition of the component, of the top and bottom tool, as well as by the allocation of the material and machine parameters. Reliable findings Forming target: steering knuckle (cross-section) The right design. Billet Pre-form Finisher In the example both operations are to be effected at the same time (one descent of the press). Here, the required total force adds up from the force required for the pre-form and for the finisher. This results in a calculated value of approx. 19.000 kN. Thus, the optimum machine for the operation from the LASCO programme is a VPE 2000 with a Fmax of 20.000 kN. Six different effects of the forming process can be simulated and effectively evaluated in graphs and tables: degree of deformation, temperature, yield stress, forming speed, flow lines and tooling. Moreover, the process can also be shown as an animation. The calculation time required for an animation is – depending on the complexity of the geometry of the component and on the number of process parame- Summary: The advantages of simulating forming processes . . . .

The expressiveness and the reliability of the calculations likewise convince experienced designers and practical users. Undesirable forming effects for reasons of wrong billets, tools or stages – such as flaws or buckling, etc. – are detected by the computer without remorse. Already at the end of the study the optimum process will have been defined. The investor can renounce to expensive test forging with sample tools. Compared with traditional methods, the cost advantage resulting from this alone will quickly amount to five or six digit Euro sums. UPGRADE by LASCO - December 2002 5 In-house Share of trainees increased again Honours in connection with jubilees Competence, readiness for duty and efficiency Coburg. Even companies looking back at a long tradition don’t have an occasion to honour longstanding and meritorious employees every day. On the same day LASCO was able to thank a total of four men for their 40 or 25 year commitment. During a ceremony, President Friedrich Herdan paid tribute to the achievements of Chief Engineer Günter Hofmann (see report on page 7), Kurt Fey, as well as Matthias Löffler and Ulrich Hofmann, over the years in various fields of activity and areas of responsibility for the company. When handing over the diplomas of the Chamber of Industry and Commerce and the decorations of the Kuratorium der Bayerischen Wirtschaft (Board of Trustees of the Bavarian Economy), Mr. Herdan said that LASCO holds them in high esteem and thanks them. Günter Hofmann can look back at 40 years in our company. After he joined the company in August 1962 he was trained as a machinist for three and a half years. Having passed his final exams successfully, he was accepted as a mechanic for machining and soon qualified as the operator of a boring mill. Kurt Fey joined LASCO in September 1977 as a sales and project engineer. After he had initially been responsible for the inner German markets and for Eastern Europe, he was entrusted with the management of the sales department in 1980. His task has consisted and consists of organising international sales. The expansion of business activities brought along a re-organisation of LASCO. As of 2000 Kurt Fey has become department manager with Prokura (authorised signature) in the sales department. Also in 1977 Matthias Löffler started his career as a trainee for technical draftsman. After successful final exams, he was entrusted with demanding tasks in designing automation systems for forging machines already at an early stage. In parallel with his work, Löffler qualified further as a technician for mechanical engineering and passed his exams very successfully in 1993. In 1998 he was appointed the assistant manager of the design areas automation and forging technology. Intensive training. For three days these four trainees from Leuwico, a manufacturer of office furniture, intensively tackled the programming and maintenance of programmable controllers at LASCO.

LASCO has for the first time supported intercompany training courses with the aim of providing young people with the best professional training possible. had an intensive training in the programming and maintenance of programmable controllers at the modern equipment available in the LASCO training section. Four trainees as industrial mechanic with the specialisation on production technology from the renowned manufacturer of office and CAD furniture Leuwico (Meeder-Wiesenfeld) were our guests for three days. During this time they A company which trains people is obliged by the training regulations to provide its trainees with the expert knowledge in this field in the fourth year of training. However, Leuwico lacks the technical facilities to do so. Personnel In July Emile Fortanier (46) has come in as a reinforcement for the team of sales engiFortanier neers.

Before joining LASCO he had been successful in the management of a retailer for home entertainment products for 18 years. As of July 1, 2002, Jürgen Ströbele is in charge of the quality assurance department. StröbeStröbele le was trained as a machinist at LASCO. Afterwards he worked in the quality assurance department and externally qualified as an industrial master at the beginning of the 90ies. Having rejoined the company in 1995, he worked as quality tester at the beginning and later on as assistant manager for the quality assurance department. Coburg. Against the background of growing demands to the spectre of competence in mechanical engineering (see article page 2) LASCO has once again increased the investments in training efforts – in particular in the industrial and technical section. After leaving school, ten young people started their professional training at LASCO in September. More than two thirds of the new trainees are trained for industrial and technical occupations: three mechatronics, three industrial mechanics with the specialisation on machine and system technology and one machining mechanic with a specialisation on milling technology. The commercial trainees are trained as female white-collar workers (2) and as white-collar worker for computer sciences (1). With the new ones, the number of trainees at LASCO has reached 41. This corresponds to a share of 14 per cent. For years this share has been clearly above average in the industry. Our company understands the training efforts as an investment in safe-guarding its future. 10 years with LASCO Dr. Hans Kühnlenz, Quality Management 01.07.2002 Mario Sollmann, Varnishing Dept. 16.07.2002 Stefan Fink, Electrical Fitting Dept. 01.09.2002 Recently retired Peter Reißenberger, Fitting Dept. 30.09.2002 Bernhard Ströhlein, Purchasing Dept. 30.11.2002 Sadly mourned Helmut Dumdey, Pensioner † 17.08.2002 Reinhold Schilling, Pensioner † 23.10.2002 In-house House magazine FH-Web-Site with LMS assistance The advanced technical college at Coburg (FH) has completely reviewed its web-site with the assistance of the LASCO branch Multimedia Services (LMS).

A content management system facilitates the continued up-dating of this internet application aiming at international objectives. New standard: DIN EN ISO 9001:2000 Significant expansion of quality management Coburg. One year earlier than necessary LASCO has again been successfully certified per the expanded standard DIN EN ISO 9001:2000. This certification had been preceded by a comprehensive revision of the quality management system with the objective of increasing customer satisfaction further. Already at the end of a two month testing phase it had become obvious that the objectives related to the reformation of the quality management system Congratulations. Chief Engineer Günter Hofmann (left, with congratulator Friedrich Herdan) has devoted almost his entire professional life to LASCO. A guarantor for efficiency Untiring for 40 years Coburg. On the occasion of the jubilee of Prokurist (authorised signatory) and Chief Engineer Günter Hofmann, President Friedrich Herdan attested him "commitment above average and outstanding capabilities”. Messe 2003 40 years ago – on 1st of August 1962 – the present head of all design departments joined LASCO as a designer. As the head of the department hydraulic presses (1970-80), the head of the design department with overall Prokura (authorised signature) for the technical section of mechanical engineering (1980-99) and in addition as head of the special branch of research/development/production planning he has rendered outstanding services to the company. In recognition of his merits he was appointed Chief Engineer. At the end of the 80ies he developed the technical basis for the success of the new section mechanical engineering/building material industry. have been reached in full, said President Friedrich Herdan. However, he conceded that the lasting effects of these changes could be assessed only at a later date. For the time being, the successful certification by the Deutsche Gesellschaft zur Qualitätssicherung (Frankfurt/Main) in November were a confirmation of the fact that the company is on the right track. The potential for improvements recognised during the several-day audit would be integrated into the system. In compa- rison with the old edition of 1994, the revised DIN EN ISO mainly tightens the criteria for the measurability of the obtaining of quality objectives, for the proof of customer satisfaction, for the proof of training efficiency and for the proof as to product and process capacity. In 1993, LASCO had had certified its quality management as one of the first mechanical engineering companies in Germany according to this standard. LASCO at the High-Tech-day of the FH Coburg A high-light on technological transfer Coburg. Technological transfer in practical application was high-lighted by the second High-Tech-day of the FH Coburg. This event – last year initiated by the Bavarian Government - took place again for reasons of the great public interest. In contrast to the first event, this time the group of exhibitors from our region was a more intimate one. The intention was to demonstrate how closely the advanced technical college (FH) and the economy cooperate under practical conditions. Special, however, not exclusive interest was placed in the engineering faculties. In view of these objectives it wasn’t astonishing that LASCO was near the top of the list of companies invited by the advanced technical college (FH). For many years the advanced technical college (FH) and LASCO have been closely linked. LASCO does not only support the engineering education by technical appliances, traineeships and dissertations submitted for diplomas. Often, the FH graduates are first choice when experts and managers are recruited by LASCO.

On the occasion of the Second High-Tech-Day at the Advanced Technical College Coburg, LASCO explained, how the exchange between industry and college works in practice. UPGRADE by LASCO - December 2002 7 Interview In practice Producers’ co-operative invests in LASCO screw press GRÜNES HERZ in Thuringia quickens its heartbeat SIGMAR RECKNAGEL Head of the Technical Department, metal processing company GRÜNES HERZ eG Unterschönau Not imaginable being better UPGRADE: Mr. Recknagel, how did GRÜNES HERZ find LASCO as a partner? Sigmar Recknagel: We had inspected the possible suppliers very well before making an investment. LASCO had always caught our attention owing to the consistently positive evaluation in the trade press. When making contact initially, we noted with pleasure the enormous spectre offered for hot forming and the uncompromising commitment to customer requirements. UPGRADE: Although your company ordered a LASCO unit for the first time, you agreed to provide a reference for the recently developed or improved control system with frequency converter. Recknagel: This is true. During the testing phase we were sceptical for two days, as then our expectations were not met. However, already on the third day we saw the break-through. Now, we are absolutely delighted with this technology. Unterschönau. A person wandering through the romantic landscapes of the Thuringian Forest between Oberhof and Steinbach-Hallenberg will hardly assume that productive hearts exist in those green valleys. Perhaps it’s also for this reason that the co-operative GRÜNES HERZ (engl.: Green Heart) in Unterschönau choose this name. Not only its name is an extraordinary feature of GRÜNES HERZ. Its legal form of a registered co-operative society is an exception among the production companies in Germany, too. In the same way as the location this is linked to tradition, which, with justification, is held high in Thuringia. Metal exploitation and machining has a long history in and around Steinbach-Hallenberg. As early as in the 14th century they started to mine for ore there. The utilisation of water power brought about small workshops causing a rapid industrialisation of this region. In 1958, seven longstanding craftsman companies combined to form the metal processing company GRÜNES HERZ. Following its nationalisation by the government of the GDR in 1972, in the context of the reunification in 1990 on this basis 67 share-holders (members) founded the company anew as a producers’ co-operative. The centre of the production programme form connecting parts (bolts) for roadand rail-bound vehicles and for machine tool construction. They are manufactured by about 50 employees in small, medium and large series according to the specific requests of the customers. The materials used are lowalloy and high-allow quality steel, fine steel and special materials. The spectre is complemented by a galvanising section with washing and draining unit and a section for plastic mould injection. The hardening, tempering and hot galvanising of the products is carried out by certified partners. Innovative special design Within the framework of the comprehensive moder- UPGRADE: Why is this so? Recknagel: We can control the energy of the ram between 1 and 100 per cent with an accuracy of one per cent. This permits a really universal utilisation of the screw press for our production requirements determined by small series. We never had imagined such a gigantic performance of the press. UPGRADE: And the supplier’s performance? Recknagel: A perfect one. 8 UPGRADE Recently acquired.

Typical examples from the range of products of the producers’ co-operative GRÜNES HERZ in Thuringia. nisation programme started by GRÜNES HERZ in the 90ies, they have invested in a LASCO screw press type SPP 315 with hydraulic drive. This special design for the production of bolt-shaped parts with a length of 450 mm is the first unit equipped by LASCO with a newly developed converter. This electronic component controlling the motor by impulses permits a more sensitive adjustment of the energy of the ram and of the press force of the machine. This is essential for the forming of very precise contours and, in comparison to traditional solutions, considerably reduces energy consumption and tool wear. The screw press has been designed with a special stroke of 450 mm to account for the long components. An additional ejector, which carefully removes the components from the tool after the forming process, is an other extra of this press providing a press force of up to 6.300 kN. While this recent acquisition has just been put into operation, in view of the good order situation further investments are planned by the management. It’s not only in Thuringia that one notes with pleasure that GRÜNES HERZ quickens its heartbeat.
