Tool technology for high accuracy micro Part Stamping

Objective



Objectives and content
Miniaturisation of technical products is an item, which
is aimed in many industrial areas. A major criteria for
this progress is the availability of cheap and high
quality manufacturing methods for the mass production of
metal micro parts. The presently applied technologies
for the production of micro parts (e.g. etching) are
expensive, time-consuming and have a high environmental
load. Fast, flexible and cheap technologies for the mass
production of micro parts should be improved or developed
so that Europe can keep up with other high industrialised
countries, especially Japan, and to make it competitive
with low wage countries.
The aim of the Consortium is to develop new techniques
and to integrate them into the stamping process to enable
this method as a fast and low costs industrial process
for the production of metal micro parts. The target is
to achieve dimensions and accuracies of micro parts,
which today can only be reached by very expensive
processes, such as LIGA.
The resulting micro-parts can be applied to a range of
products, such as:
all kind of connectors for Electronic applications
(e.g. lead frames).
watch parts.
parts for consumers, (e.g. razors with thin membranes).
parts for medical applications (e.g. tools for minimal
invasive therapy).
parts for micro-systems.
The method is applicable in every sector of industrial
production where less expensive and metal micro-parts
with structure sizes down to 100 mm and accuracies less
than 5 mm are necessary. To obtain the desired accuracy
in an industrial production process, all influencing
parameters of the stamping process have to be
investigated. Those are:
tool technology, esp. hybrid tools.
process conditions with flexible tool set up.
new and improved materials for tools and products.
The stamping process will be developed by a consortium,
where complementary technologies from electronics,
consumer industry, laser technology and tool
manufacturers will lead to a synergy effect with new and
unconventional approaches for high accurate stamping.
The results will be demonstrated on different micro-parts
which can be directly used for production.
