| Mould Sweating |
|
The biggest challenge that moulders face today is to produce
the moulded component at better cycle time. The most time
consuming step in moulding cycle is cooling time. To bring
the cooling time down, as close as possible to refilling time
(dosing time), the mould needs to be cooled with chilled water
as low as possible. During this process of bringing down the
temperature of the mould, due to higher grains surrounding
the mould, condensation occurs. This is defined as mould
sweating. Mould sweating can lead to rusting of mould, water
marks on moulded component and moulded component not
getting ejected out properly. |

| Bry-Air solution to mould sweating |
| To eliminate the condensation, the area around the
mould needs t o
be maintained with
Dry-Air at the dewpoint
o f - 50C to - 100C .
Bry-Air offers the solution
through Mould Dehumidification Systems – MDS and PMD.
The Mould Dehumidification System
functions by blanketing
the mould surface with
a constant supply of
dehumidified air at an appropriate
dewpoint below that of the chilled
water in the mould. |
| The Bry-Air MDS is a very sturdy and energy efficient
unit which provides a constant supply of dry air around
the mould at precisely controlled dewpoint. |

| Maintaining a mould while offline. |
| Moulds are expensive and need to be stored properly.
Slipshod maintenance/ management and other agents could
damage expensive mould. It has been noticed that moisture
causes large scale damage to the mould when it is not stored
properly. Damaged mould leads to surface defects on the
material and dimensional inaccuracy. Also it
leads to lower life time of the mould and higher
maintenance cost.Proper storage under
dehumidified condition could ensure that
expensive moulds lasts several
life cycles with no maintenance.
Bry-Air mould dehumidifiers
ensures protection of precious
mould during storage. |
