Smart Injection system
Hall 6 - D72
saves time and cost
Smart Injection is a mechanical
resin transfer device that makes it
possible to manufacture RTM parts
without using a conventional injection machine. Smart Injection is a fast
process that saves preparation time. As
there is no injection machine, there is no
need to connect the silicon tubes and to
replace or clean them, thus eliminating
steps from the traditional manufacturing cycle. With Smart Injection,
the resin is polymerized directly in the mould during the part curing
stage, so there is no extra cleaning step. Furthermore, risks are limited
because the resin does not circulate in silicone tubes and the only cleaning operation concerns polymerized resin. Smart Injection is easy to
use as the system is designed and integrated into the moulds directly,
but it can also be added and adapted to existing moulds no matter the
injection pressure. It facilitates the resin transfer process as there is no
need to manage the heated resin flow as usually between an injection
machine and a mould. This device can also easily automate the injection
step, therefore providing high reproducibility in accordance with the
injection parameters. The device also lowers recurring manufacturing
costs and resin consumption (up to 80%) as it substantially reduces the
amount of extra resin necessary for each part, thus reducing resin waste
but also consumables such as silicone tubes, fittings and cleaning products.

New winding pins for enhanced
Hall 5 - E56
rotational symmetry
Leichtbau-Zentrum Sachsen developed innovative winding pins that
improve the filament winding process, resulting in rotationally-symmetric fibre-reinforced plastic (FRP) components such as pipes, masts,
drive shafts or pressure vessels, the latter two being important for future hybrid vehicles. FRP components such as drive shafts or pressure vessels are still restricted to high-end
applications due to high part costs
resulting not only from the material
price but also from low-efficiency
manufacturing and assembly processes. This was the starting point for
this innovation for filament winding
machines.
With this innovation, the set-up time of the filament winding machine is reduced to about 50% compared to classical winding pins. The new pins improve the filament winding process, meaning that filament winding at angles
below 10° with precise fibre placement is achieved, resulting in a component
with enhanced mechanical properties. Furthermore, additional fibre layers
can be reduced for safety reasons and turning zones are obsolete due to precise fibre placement. Therefore, the resulting wound components need less
fibre material. With this product, the application barrier for composite drive
shafts and pressure vessels can be lowered and new markets can be opened.
The winding pins allows efficient production of wound FRP components
with enhanced mechanical properties and reduced material consumption.
