Staying ahead of the game has always been
the watchword at World Cat and to this end
the company has started to introduce core infusion
molding in order to further improve
laminate quality, virtually eliminate VOCs
(Volatile Organic Compounds) emissions
and achieve better cycle times.
Achieving better cycle times is particularly
critical for World Cat as demand for its
boats has doubled over the last 12 months.
Rather than ‘go at it alone’ World Cat
decided to partner with Diab in order to
speed the introduction of core infusion
molding and minimize any teething problems.
Diab has pioneered the use of core
infusion in the marine market with its process engineering teams around the world being
directly involved in the infusion of well
over 200 different types of vessel – everything
from a 3 meter (10 ft.) dinghy to megayachts
in excess of 45 meters (150 ft.).
In the case of World Cat, Diab was
contracted to supply the grooved and perforated
infusion core materials. Composites
Consulting Group, a Diab Group Company,
was contracted to carry out flow modeling,
undertake infusion training, and be directly
involved in the first infusion – a 320
Center Console hull.
After the training and the success of the
first infusion, the World Cat team felt confident
to carry out further hull infusions without
assistance. The lay-up and infusion is carried
out by a four person team in just three days.
After hull number five was produced a
Diab process engineer was again on site to
further refine the process and address any
concerns from the World Cat build team.
Already, the company is achieving a faster
turn around with the molding of a 320CC
hull being reduced by a day.
In addition by infusing the fully-cored
hull of the 320CC, World Cat has been able
to reduce overall weight while increasing
structural stability. The weight reduction
has led directly to better fuel consumption,
higher speeds and greater range.
With the success of the 320CC, World
Cat is planning to gradually introduce core
infusion across its entire range. In addition
other members of the PowerCat Group –
Glacier Bay, Livingston Cats and Carolina
Cats will also be introducing this technology
over the next few years.
