SMARTFLOW®
Mold Temperature Regulator
Operating Instructions
General
The Smartflow Mold Temperature Regulator controls the temperature
of cooling water exiting a mold, thereby regulating the mold
temperature.
A mold is heated by the resin shot. The heat from the mold is
transferred to the cooling water. The regulator senses the water
temperature and restricts the cooling water flow, giving it time to be
heated by the mold, until it reaches the desired set point. The
regulator valve slowly widens to allow the cooling water to go
through at a rate that will hold the mold temperature at a value that
corresponds to the set point.
Remember that the mold temperature is always hotter than the
cooling water return temperature.
Mode of Operation
When the temperature of the cooling water is greater than the desired
set point, the regulator adjusts the valve opening to increase flow.
When the cooling water temperature is less than the desired set point,
the valve opening closes, decreasing flow. The set point is adjusted
with the control knob on the end of the unit. A thermometer provides
visual indication of the cooling water temperature.
Since every mold is different, data is not available for every
situation. The molder should determine the outgoing coolant
temperature, and make adjustments based on experience.
Flushing
The Smartflow Mold Temperature Regulator incorporates a special
flush feature to remove particles which may become lodged inside.
By turning the control knob fully clockwise, the valve is completely
open. Any foreign particles should be removed by the increased
cooling water flow. After flushing, return the unit to original setting.
Special Notes
Molders are cautioned that the Smartflow regulator will not work for
every mold size. Molders making very small parts may not have
enough heat from the resin shot to heat the mold adequately.
Generally, the regulator can be used where the cooling water supply
is cooler than the water exiting the mold.
