Critical Cooling Processes within Plastic Moulding Industry
The cooling process within plastic injection moulding is very critical to the quality of the product being moulded, and takes
approximately 50-75% of the total cycle time. Therefore, it is critical to maintain clean, efficient cooling channels capable
of removing heat at the required rates. Any deviation to that would result in an inconsistent moulding quality from cycle to cycle.
When mineral deposits from the cooling water drop out of solution and attach to the cooling channel walls of your moulds
or heat exchanger
tubes of your hydraulic oil coolers, a thermal barrier is created which significantly reduces heat transfer. The resulting
uneven temperature of the mould surface (uneven shrinkage) results in parts with moulded-in stresses, warped/twisted
sections, sink marks, poor surface appearance and varying part dimensions from cycle to cycle.

Cycle time down? - Inconsistent moulding?
Have you checked your cooling channels?
Many moulds are running at very poor cooling efficiency without you even knowing it.
Over months and years layers of limescale, rust or other debris slowly reduce the bore size of your cooling
channels, which can have a dramatic effect on the overall performance of each mould.

Preventative maintenance is so much more affordable than unplanned plant breakdowns and forced shutdowns, that it is hardly worth
taking the gamble and risking your production commitments to your customers that rely on your factory to manufacture
and deliver their commodities on their time schedule.
All ScaleAway descaling products are fortified with corrosion inhibitors, surfactants, detergent builders and
defoamers, designed to dissolve the toughest water scale, lime, mud, and rust deposits from virtually any piece of
water-based heat transfer equipment.
ScaleAway scientifically formulated descaling solutions can be utilized to clean an isolated piece of equipment using
a ScaleAway System Descaling Cart
The descaling product of choice is ScaleAway Lime-Go which is very fast acting, and most of your applications can be
cleaned in a matter of hours.
ScaleAway Lime-Go will dissolve about 1/2 kilogram (500g) of water limescale per five kilograms (5kg) of ScaleAway Lime-Go.
Mould Descaling Chemicals:
ScaleAway Lime-Go - Locally manufactured Descaler for Heat Exchangers.
RYDLYME - International Descaler for Heat Exchangers from the USA.
While ScaleAway Lime-Go is the industry leader in southern africa in the plastic injection moulding industry.
An American alternative
is also available called RYDLYME Biodegradable Descaler.
RYDLYME is an NSF Certified product and is the worldide industry leader.
Temperature Control Unit Heat Exchangers
Support equipment, such as chillers, exchangers, temperature controllers and cooling towers are a vital part of your
operation and can only afford you efficient operation when kept clean of water scale, lime and rust deposits.
Call today and speak to one of our experienced technicians for more detailed instructions on in-house descaling when using
the ScaleAway System Descaling Cart or ScaleAway Scheduled Preventative Maintenance Plan for your water operated equipment.
Any type of water cooled heat transfer equipment can usually be cleaned with ScaleAway descaling products. Hydraulic oil
coolers that become fouled with water scale, lime and rust deposits will eventually cause a shutdown and replacement of expensive
production equipment.
Periodic cleaning of your moulds, hydraulic oil coolers and other heat transfer equipment will keep them operating efficiently.
ScaleAway descaling products are our solution to your over heating problems.
Heat transfer efficiency is reduced by 30% with only 1mm of limescale build-up! The thicker the scaling the less efficient your heat transfer equipment is!!!
