And to assistance with product
developments and industrial
projects
A series of industrial applications for previous R&D work
began in 2012: very high-strength steel for engine bolts,
high-strength security bolts (class 12.9) for the chassis,
new types of steel for cemented parts applied to valve
cut-outs.
In the area of surface treatments, new solutions were
proposed to reduce the environmental impact of our
processes via, in particular, the elimination of CMR compo-
sites and solvents, and lines with zero liquid wastage.
The calculation team provides support for all projects
involving digital simulation: calculation of structures,
modeling of deformation operations on steel and plastic
injection.
An audit of all the laboratories and the certified heat
treatment lines of LISI AUTOMOTIVE was carried out
jointly with the Quality Department. The objective was
to ensure that, throughout the world, critical installations
benefit from the same level of organization and technical
skills. For this purpose, all the plants must be able to meet,
in an irreproachable way, the requirements of the interna-
tional referentials for heat treatments: CQI9, VDA, RQP1.
They will be supported by the multidisciplinary team of
the “Year of heat treatment” project, which will share its
experience.
Projects contributed
by partnerships
In parallel with the integration of a part of the develop-
ment and R&D team of Stryker Benoist Girard, LISI
MEDICAL also integrated itself into the working group on
traceability by RFID, where the instrumentation used for
bone marrow surgery is concerned. This group, comprised
of subcontractors, manufacturers and hospitals, was born
from a requirement by the end user to have a simple and
efficient tracking for instruments.
In addition, LISI MEDICAL is part of a working group on
polishing methods and checking of polished products,
with a partner specializing in this area, and under
the aegis of the Ministry for Production Recovery. The
ambition of this group is to improve the very widespread
polishing techniques in the area of articulation (cemented
hip joints, double action sockets), but also to define the
criteria for assessing the quality of the polishing obtained.
Where manufacturing processes are concerned, LISI
MEDICAL has developed, within the unit at Caen, an
automated process for the hot lamination of components
prior to hot forging, allowing it to make this shaping
process more reproducible. The system will be deployed
on other lamination processes in 2013. On the site in
Lyon, the implementation of a control-environment unit,
dedicated entirely to the machining of plastic materials
(polyethylene and PEEK), allows for access to very widely
used products in the area of spinal surgery.
