The story…

Since July ,1st, 1909 we have been dealing with non-ferrousmetals. Starting from these roots, always trying to improveourselves and explore new frontiers, we have experienced manytechnologies 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 develophydroforming technology.

This technology allows to shape tubes and sheets of aluminium, stainless steel and every other metal by using pressed water. Byusing hydroforming, designers’ creativeness can get rid of the limits of the traditional press technologies in order to achieveextraordinary aesthetical standards with the same mechanicalfeatures 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 startedin 2004 was focused on THF ( Tubes HydroForming) in order toproduce items with different sections without any welding processstarting from metal extruded tubes.

The project was settled to increase company competitivenessdeveloping 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 sincethe traditional buckling technologies made with a core can work just in the direction the core is pushed ahead. Moreover it ispossible to make undercut as water flows when pressurevanishes.

The R&D project - 1

We therefore decided to go on with our project in THF (TubesHydro Forming) using what we have learnt in the previous tests toshape two tubes one inside the other, at the same time. We tookgreat advantage by using simulation softwares (Forge and Autoform) we have been using since 2005. These softwares let usincrease 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 chromeplating of the pipe. At the same time we started working also on items for furniture with very inventive shapes which were veryexpensive 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 traditionalcasting and to make prototypes which could replace traditionalsoldered motorcycle frames with only one high resistant steel hydroformed part. We have also improved the hydroformingtechnology for the buckling of sheets in the small batch of production items.

At this stage the research has focused on the precompetitivedevelopment, on the hydroforming process industrialization, and on the improvement of the simulation techniques. All theseexperiences have highlighted a growing attention to thistechnological 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 ourknowledge 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 havehighlighted unbelievable opportunities in the use of heat.We are still at an early stage of the search for a technical solutionable to find all the advantages coming from plasticity of the high temperature of the item. A solution to this particular problemwould widen the utilization possibilities of this technologyenormously.

Our latest investment

In 2008 Maspero bought a new hydroforming press with closingstrength 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 customersand to give a deeper meaning to the idea of productivepartnership.
