HYDROFORMING an Opportunity for You in Our Business HYDROFORMING An opportunity for You in our business Address: via Ercolano 2 tel: (+ 39) 039 20 45 21 fax: (+ 39) 039 59 64 588 I-20052 Monza MI - Italy [email protected] www.maspero.it The story… Since July ,1st, 1909 we have been dealing with non-ferrous metals. Starting from these roots, always trying to improve ourselves and explore new frontiers, we have experienced many technologies and achieved a very high competence in our core business: non ferrous-metal hot forging. HYDROFORMING : Why In 2004 our company made a Business Unit to develop hydroforming technology. This technology allows to shape tubes and sheets of aluminium, stainless steel and every other metal by using pressed water. By using hydroforming, designers’ creativeness can get rid of the limits of the traditional press technologies in order to achieve extraordinary aesthetical standards with the same mechanical features of the items made with traditional technologies. Hydroforming process scheme for tubes – THF Let’s start from the beginning… The first R & D project concerning Hydroforming Maspero started in 2004 was focused on THF ( Tubes HydroForming) in order to produce items with different sections without any welding process starting from metal extruded tubes. The project was settled to increase company competitiveness developing our knowledge in a technology fit to exploit the physical property of water to transmit pressure in every direction with the same force when pressed. This feature is important since the traditional buckling technologies made with a core can work just in the direction the core is pushed ahead. Moreover it is possible to make undercut as water flows when pressure vanishes. The R&D project - 1 We therefore decided to go on with our project in THF (Tubes Hydro Forming) using what we have learnt in the previous tests to shape two tubes one inside the other, at the same time. We took great advantage by using simulation softwares (Forge and Autoform) we have been using since 2005. These softwares let us increase our knowledge, engineer hydroforming processes and increase our speed in answering to our Customers. This step of the project was mainly involved in the production of a motorcycle exhausted pipe made of two different tubes one inside the other in order to give a long lasting life to the chrome plating of the pipe. At the same time we started working also on items for furniture with very inventive shapes which were very expensive to produce with traditional technologies, thus giving the designers new opportunities to their creativity. Research project After further tests we started to develop tap and fitting items of innovating shape which couldn’t be produced through traditional casting and to make prototypes which could replace traditional soldered motorcycle frames with only one high resistant steel hydroformed part. We have also improved the hydroforming technology for the buckling of sheets in the small batch of production items. At this stage the research has focused on the precompetitive development, on the hydroforming process industrialization, and on the improvement of the simulation techniques. All these experiences have highlighted a growing attention to this technological process, often hindered by too heavy costs of the tools in the past. The aim of this stage of the project has been to deepen our knowledge of the process, in order to be able to industrialize the hydroforming productive process. Where we are now Now we have a new bound to explore, how changing in the temperature affects the possible result. All the previous experiences and tried simulations have highlighted unbelievable opportunities in the use of heat. We are still at an early stage of the search for a technical solution able to find all the advantages coming from plasticity of the high temperature of the item. A solution to this particular problem would widen the utilization possibilities of this technology enormously. Our latest investment In 2008 Maspero bought a new hydroforming press with closing strength of 3,000 tons and hydroforming maximum pression of 4,000 Bars. This investment was made in order to offer a more complete range of productive technologies to our customers and to give a deeper meaning to the idea of productive partnership.

  • Under the Direction of Dr. Gracious Ngaile)
    ABSTRACT LOWRIE, JAMES BALLANFONTE. Development of a Micro-Tube Hydroforming System. (Under the direction of Dr. Gracious Ngaile). The rising demand for small parts with complex shapes for micro-electrical mechanical systems (MEMS) and medical applications has caused researchers to focus on metal forming as a possible way to mass produce miniature components. Studies into the miniaturization of macro-scale metal forming processes have mainly been focused in the sheet metal and extrusion fields and only a few researchers have attempted to take on the problem of miniaturizing the tube hydroforming process. The research that has been done into micro- tube hydroforming has been limited to simple expansion studies and no researchers have yet been able to combine axial feeding of the ends of the micro-tubular blank with simultaneous expansion of the tube. This has significantly reduced the complexity of the micro-parts which can be created using the tube hydroforming system. Combining material feed and expansion must be accomplished in order to create a micro-tube hydroforming process which is capable of producing metallic components with complex tubular geometries. The major objective of the research presented in this thesis is the development of a micro- tube hydroforming system which is capable supplying both axial feed and expansion to the tube simultaneously. This was accomplished by first breaking down the concepts of the conventional hydroforming tooling so that they could be analyzed for problems when being scaled down. Once the problems with the conventional tooling and the basic needs of the hydroforming system were established, the information was used to develop a new form a hydroforming tooling, called floating die tooling, which could apply both material feed and expansion to tubular blanks.

  • Magnesium Casting Technology for Structural Applications
    Available online at www.sciencedirect.com Journal of Magnesium and Alloys 1 (2013) 2e22 www.elsevier.com/journals/journal-of-magnesium-and-alloys/2213-9567 Full length article Magnesium casting technology for structural applications Alan A. Luo a,b,* a Department of Materials Science and Engineering, The Ohio State University, Columbus, OH, USA b Department of Integrated Systems Engineering, The Ohio State University, Columbus, OH, USA Abstract This paper summarizes the melting and casting processes for magnesium alloys. It also reviews the historical development of magnesium castings and their structural uses in the western world since 1921 when Dow began producing magnesium pistons. Magnesium casting technology was well developed during and after World War II, both in gravity sand and permanent mold casting as well as high-pressure die casting, for aerospace, defense and automotive applications. In the last 20 years, most of the development has been focused on thin-wall die casting ap- plications in the automotive industry, taking advantages of the excellent castability of modern magnesium alloys. Recently, the continued expansion of magnesium casting applications into automotive, defense, aerospace, electronics and power tools has led to the diversification of casting processes into vacuum die casting, low-pressure die casting, squeeze casting, lost foam casting, ablation casting as well as semi-solid casting. This paper will also review the historical, current and potential structural use of magnesium with a focus on automotive applications. The technical challenges of magnesium structural applications are also discussed. Increasing worldwide energy demand, environment protection and government regulations will stimulate more applications of lightweight magnesium castings in the next few decades.

  • Determination of Process Parameters for Stamping and Sheet Hydroforming of Sheet Metal Parts Using Finite Element Method
    DETERMINATION OF PROCESS PARAMETERS FOR STAMPING AND SHEET HYDROFORMING OF SHEET METAL PARTS USING FINITE ELEMENT METHOD DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Hariharasudhan Palaniswamy, M.S. * * * * * The Ohio State University 2007 Dissertation Committee: Approved by Professor. Taylan Altan, Adviser __________________________ Professor. Gary L. Kinzel Adviser Professor. Henry R. Busby Graduate program in Mechanical Engineering Professor. Jerald R. Brevick Copyright by Hariharasudhan Palaniswamy 2007 ABSTRACT Increase in the complexity of the parts and emphasis on the low formability and expensive lightweight materials require the use of multipoint cushion systems in modern presses and optimal blank shapes. Thus, better control of metal flow can be achieved for increasing the drawability and reducing the scrap rate and manufacturing cost in sheet metal forming. The blank holder force (BHF) / cushion pin force /cylinder force required to program the multipoint cushion system for forming a part is difficult and costly to estimate by trial and error FE simulation and die tryouts as there more than one variable to change. Hence, multipoint cushion system available in a modern press is hardly used in practice. Estimation of BHF to program the multipoint cushion system could be best done through structured FE simulations in process design stage so that its advantages can be incorporated in process design and carried forward to die tryout and production to realize its potential. Successful application of FE simulations in stamping process design depends on the accuracy of the input parameters. Conventionally, properties of sheet materials obtained from tensile test are used in FE simulation.

  • Module 3 Selection of Manufacturing Processes
    Module 3 Selection of Manufacturing Processes Lecture 4 Design for Sheet Metal Forming Processes Instructional objectives By the end of this lecture, the student will learn the principles of several sheet metal forming processes and measures to be taken during these process to avoid various defects. Sheet Metal Forming Processes Sheet metals are widely used for industrial and consumer parts because of its capacity for being bent and formed into intricate shapes. Sheet metal parts comprise a large fraction of automotive, agricultural machinery, and aircraft components as well as consumer appliances. Successful sheet metal forming operation depends on the selection of a material with adequate formability, appropriate tooling and design of part, the surface condition of the sheet material, proper lubricants, and the process conditions such as the speed of the forming operation, forces to be applied, etc. A numbers of sheet metal forming processes such as shearing, bending, stretch forming, deep drawing, stretch drawing, press forming, hydroforming etc. are available till date. Each process is used for specific purpose and the requisite shape of the final product. Shearing Irrespective of the size of the part to be produced, the first step involves cutting the sheet into appropriate shape by the process called shearing. Shearing is a generic term which includes stamping, blanking, punching etc. Figure 3.4.1 shows a schematic diagram of shearing. When a long strip is cut into narrower widths between rotary blades, it is called slitting. Blanking is the process where a contoured part is cut between a punch and die in a press. The same process is also used to remove the unwanted part of a sheet, but then the process is referred to punching.

Of Mechanical Engineering, Mahatma Gandhi Institute of Technology, Gandipet, Hyderabad – 500075, India. Abstract – The stamping of parts from sheet metal is a During forming, a combination of increasing internal fluid straightforward operation in which the metal is shaped or cut pressure and a simultaneous axial pressing on the tube ends by through deformation by shearing, punching, drawing, stretching, the sealing punches cause the tubular material to flow into the bending, coining, etc. Production rates are high and secondary contours of the die. Tubular hydro forming is generally divided machining is generally not required to produce finished parts into three operating techniques: Low-Pressure Hydro forming within tolerances. This versatile process lends itself to low costs, since complex parts can be made in a few operations at high uses fluid pressures of 12,000 PSI/828 BAR or less. Cycle time production rates. Sheet metal has a high strength-to-weight is less than with other hydroforming methods, but components factor, enabling production of parts that are lightweight and must be designed carefully to form properly using the lower strong. Hydroforming process is divided into two main groups; fluid pressures (3-6). sheet hydroforming and tube hydroforming. Tube HydroForming (THF) is a process of forming hollow parts with different cross High-Pressure hydroforming uses fluid pressures ranging from sections by applying simultaneously an internal hydraulic 20,000 to 100,000 PSI/1,379 to 6,895 BAR.

Products are continuously undergoing evolution according to changes in trends, and the need for a high surface quality, complicated shapes, and special materials make this kind of product more and more difficult to fabricate. A product of complex geometry with detailed features is not suitable for production by a conventional forming process, but the Sheet Metal Hydroforming (SHF) process can be employed to produce very detailed features. In this study, we integrated the SHF process with a resin tooling method for the rapid manufacture of products of minimal variety in low quantities, resulting in the reduction of both cost and time. We manufactured a freeform house with a small radius fillet using SHF with resin tooling in a unique and novel process. The process involved the forming of twenty pieces using Al 5052 and SUS 304 sheet plates, and the number of items fabricated, dimensional accuracy, and endurance to wear and tear of the tools was then used to evaluate the applicability of the method in a real manufacturing process.
