Expert knowledge from mould making, injection moulding and robotics

VDMA is organizing a joint stand at MedtecLIVE with T4M in Stuttgart. Today, our exhibitor toolcraft introduces its products and solutions. You are very welcome to visit the VDMA in hall 10 booth 124e.

toolcraft AG is a pioneer of future technologies, such as additive manufacturing and the construction of
individual robot cells. As a provider of comprehensive solutions, toolcraft covers the entire process chain,
from the initial idea to manufacturing, quality assurance and testing in additive manufacturing,
machining, injection moulding and mould making. In the field of robotics, customised, fully programmed
integration solutions are implemented. Building close working relationships with collaborative partners
as well as universities, other institutions of higher education and research centres is an important part of
its corporate philosophy.

Future technology additive manufacturing meets classical machining
Additive manufacturing enables highly complex geometries with significantly reduced time and
resources. Two years ago, the medium-sized company invested in a customised LMD system with
powder nozzle from Trumpf with horizontal and vertical rotation axis. This enables "extreme high-speed
laser metal deposition" (EHLA) - developed and patented by the Fraunhofer Institute for Laser
Technology ILT.
The in-house measurement and testing laboratory provides precise answers for reliable component
quality: from the inspection of materials on receipt and process-related analyses such as density
determination, structural analysis and analysis of mechanical properties to the preparation of
comprehensive reports.
The additively manufactured raw parts are refined into the complete functional component by machining
processes. The machinery at toolcraft is always state-of-the-art. The use of multi-axis technology and
angle heads is exemplary for the innovative strength. It is possible to machine almost any material. In
addition, various furnaces, including a vacuum furnace, are available for heat treatment of the
components. To significantly expand the machining process chain, toolcraft invested in a modern
technical cleaning system at the end of 2020. With this, the finished components are finely cleaned and
packaged according to customer specifications, whereby absolute cleanliness can be guaranteed.

Expert knowledge from mould making, injection moulding and robotics
toolcraft developed a complete automated solution for the production and packaging of a cerumen filter
protector for hearing aids. For this purpose, a mould to produce very small parts was designed and
manufactured in the mould making department. A micro injection moulding system was combined with a
robot to automate the entire process. Thanks to expert knowledge in process development as well as in
camera and laser technology, toolcraft implemented component inspection by means of camera and
laser micrometer technology as well as the lasering of the packaging components in the specified cycle
time. Since then, the filter systems have been coming off the production line fully automatically on four
lines.

Certified precision
toolcraft attaches great importance to the highest standards in the quality of its precision components.
This is evidenced, among other things, by the certifications according to DIN EN ISO 9001 and EN 9100.
Since 2014, the company has been certified according to DIN EN ISO 13485 for the manufacture and
assembly of surgical tools and components for medical devices. In 2018, certifications for additive
manufacturing according to Nadcap and by TÜV Süd followed.
