1 KICKOFF MEETING LEONARDO DA VINCI PROJECT TAMPERE, 09-10/11/2006 Contribution from IRCCyN Ecole Centrale de Nantes Alain BERNARD Professor at Ecole Centrale Nantes Deputy Director for Research «Virtual Engineering for Industrial Engineering» research team of IRCCyN (Research Institute for Communication and Cybernetics of Nantes) 09-10/11/2006 Kickoff meeting - Leonardo Da Vinci project - Tampere - Prof. A. BERNARD 1

2 Key elements of the sector in France The mechanical sector is characterised by entreprises from three main industrial branches: - mechanical equipments: machines, energy equipments - industrial services for metal work or mechanical subcontracting - metallic products manufacturing 09-10/11/2006 Kickoff meeting - Leonardo Da Vinci project - Tampere - Prof. A. BERNARD 2

3 Key elements of the sector in France - a structured domain, linked to industry by customer/provider relationship - a proportion of qualified jobs higher than the one of production industry - the increasing proportion of large international group financing - innovation: integrators, architects 09-10/11/2006 Kickoff meeting - Leonardo Da Vinci project - Tampere - Prof. A. BERNARD 3

4 Key elements of the sector in France The mechanical sector has to face new challenges due to: - worlwide markets and business - the development of «extended entreprises», with a transfert of the responsabilities between customer and provider: no more «capacity subcontracting», increase of standards fo safety, health, environment - more and more requirements that impact quality, delivery time, reliability, safety - decrease of time to market and customisation of products - difficulty for attracting employees (less attractivity for young people) - the skills for mold manufacturing are in mechanics and casting 09-10/11/2006 Kickoff meeting - Leonardo Da Vinci project - Tampere - Prof. A. BERNARD 4

5 Key elements of the sector in France - mold and pattermaking manufacturing is a subcontracting activity for many sectors - mold manufacturers contribute actively to industrial toolings related to specific fabrications (rubber, plastics, glass, metal) 09-10/11/2006 Kickoff meeting - Leonardo Da Vinci project - Tampere - Prof. A. BERNARD 5

6 Key elements of the sector in France - after designer definition: model manufacturing (resin, wood, plastics,metal) - fabrication of models using traditionnal technics (machining, assembly) or rapid prototyping - use of a wide scope of competencies technologies (polishing to HSM) - necessity and benefit of working with partners sometimes not close to the company - creation of shared manufacturing units - co-design with the customer for delivery time reduction and quality increase 09-10/11/2006 Kickoff meeting - Leonardo Da Vinci project - Tampere - Prof. A. BERNARD 6

7 Key elements of the sector in France - mold, model and pattern making is a sector with companies that have less than 500 employees (SMEs), and most of them have less than 50 employees REPARTITION OF THE MARKET SECTORS Molds for rubber and plastics Molds for glass and Mineral materials Models Molds for metallic and stainless metals 09-10/11/2006 Kickoff meeting - Leonardo Da Vinci project - Tampere - Prof. A.
