“We develope an innovative solution for the differential assembly of vehicles of the future”
HISTORY OF CIE
CIE Automotive is an industrial group specialized in high added value processes: it has a team committed to an automotive project that has been growing steadily for more than 25 years.
The project began in 1996 with the creation of INSSEC and its participation in Corporación Industrial Egaña and the CIE Automotive Group. It emerged in 2002 as a result of the merger between the Egaña Group and the Aforasa Group.
COLLABORATION CIE + TECNALIA
When we talk about more sustainable advanced manufacturing processes, we are referring to a different way of understanding production as we have known it up to now. It is about being more efficient throughout the entire construction value chain, from the manufacture of the components themselves to their disposal at the end of their service life. We call it eco-efficient manufacturing.
“And we are putting it into practice through a collaboration with CIE Automotive and TECNALIA to develop an innovative solution for the differential assembly of vehicles of the future“, says Óscar Valbuena, Processes engineer CIE.
Together, we have designed a new manufacturing route through the hybridisation of two technologies to produce toothed geometries. At CIE Automotive, we carry out hot die forging on a vertical press to obtain the preform or the starting material.
Ecoefficiency, a TECNALIA & CIE Automotive project
“At TECNALIA, we semi-finish these preforms using our own rotary forging technology, making the resulting part as similar to the final geometry that will form part of the vehicle differential”, Sonia Varela, Project manager, TECNALIA.
Thanks to the combination of these two advanced manufacturing processes, we have achieved greater efficiency by increasing savings in raw materials, which also leads to a reduction in the energy consumed and the final machining costs.
It is a technological solution that can be applied to parts of similar technical complexity in different areas and sectors, and can even pave the way for new lightweight re-designs.
“It results in components with better properties and higher added value for vehicles of the future“, Óscar Valbuena.
“Designing new eco-efficient processes is our way of contributing to the sustainable development of industry, society and the whole planet”, Sonia Varela.
