RTM Skin, an innovative process
in the wind energy sector
By
MVC, a specialist in production technologies for engineering
plastic components, intends to increase its revenue in the wind
power sector by 300% by 2015. This forecast is based on the
strong growth expected in Brazil due to about US$ 12 billion
expected investments and the construction of new wind farms.
Gilmar Lima
Director
MVC
l
n 2014, MVC plans to supply 300
complete nacelle sets (body) and
windmill spinners (nose). By 2015,
it should produce and deliver 800
sets to several customers in the wind
energy generation market and reach
US$ 35 million of revenue in this
sector alone. The company is thus
accomplishing the goal established
two years ago.
as it does not use auxiliary materials
such as hoses, peel ply, net bleeder,
and film, which no longer need to be
discarded. Besides saving consumable
costs, labour is drastically reduced.
A part that required about 8 hours to
be manufactured using the traditional
infusion process can now be produced
in only 1 hour with the new method.
Complex part manufacturing
Another advantage of RTM Skin is the
possibility to manufacture complex
parts with negative demoulding. With
a flexible counter-mould, the whole
mould handling operation during the
process becomes faster and easier.
The RTM Skin technology involves
the following four steps (Fig.1)
Innovative technology
The company's robust growth in this
sector is based on the development of
a new production technology: RTM
Skin (Resin Transfer Moulding). This
process replaces the infusion process
and is perfect for large parts. With this
technology, a silicone skin is used as a
counter-mould.
The injection lines are located in
the counter-mould, and due to its
flexibility, it is possible to compress
the compound to ensure the high glass
content required for wind turbine
parts. This vacuum technology provides a more sustainable alternative
