Freeze Trim - barwell

The barwell Freeze Trim is a compact range of
time-saving and quality enhancing cryogenic
deflashing machines specifically designed to meet the
most exacting demands of the rubber, plastics and
metal industries.
• A multi-material deflashing solution providing
complete processing flexibility from one machine
• A quality enhancing method of deflashing
• A system which increases productivity due to its
exceptionally fast running speed
• An automated cost-cutting method which
dramatically decreases operational and labour costs
• An environmentally-friendly, safe, reliable and
simple-to-operate machine
Why choose the barwell Freeze Trim
Unwanted flash is created
during moulding when
material overflows the
mould cavity. This is
usually removed by:
rotary tumbling, hand
trimming, punching, using
chemicals or by grinding.
However, these methods are tedious and time consuming
and not always effective. Cryogenic deflashing is by
far the most versatile, effective and economic option.
Improved product quality
The Freeze Trim will produce a high quality part as all
parts are exposed to the blast media ensuring an
even, clean and complete removal of inner and outer
diameter flashing in just one operation. Surface
damage is also avoided e.g. scuffing, scratching and
cut marks.
Increased production and processing flexibility
The fully automated process significantly decreases
deflashing time and increases production. Freeze Trim
offers complete flexibility to multi-material processors.
The use of gaseous
nitrogen to circulate
the media increases
life of the media over
the Auger method of
deflashing.
Simple operation with reliability and easy maintenance
Installation is simple, even when space is limited and
minimal user training is required. Time, tumble speed
and media velocity can be programmed which is
simplified by the latest PLC controls and touch screen
interface with access to a 2000 item database for easy
retrieval of set-up.
Reduced operational costs
Major savings can be achieved on
labour costs due to speed of
operation. Wastage is also
dramatically reduced due to the higher
finish quality. Savings can also be made as the unit
takes up considerably less factory space than most
other processes.
Safe and environmentally friendly
Blast media can be re-used as it is separated from the
flash after production. GN media assist helps to avoid
media from sticking due to moisture. The media can
be used for approx. 300 cycles.
Liquid nitrogen is safely recycled or vented into the
atmosphere.
There is no risk of hand
cutting, as with trimming,
or safety concerns such as;
splash backs from molten
baths or harm from toxic
fumes and dust from
chemical deflashing.
