 ELECTRICALLY HEATED PLATENS
Electrically heated presses feature PHI special design
platens and digital set point temperature controllers with time
proportioning and automatic reset for uniform and predictable platen
heating.
Heavy duty bolsters, insulated from hot platens, and
large diameter ram insure that deflection is kept to a minimum while
providing lower hydraulic system pressure resulting in reduced
hydraulic maintenance requirements.
Selector switches and timers are provided for either
manual or automatic operation.
Obviously, the more accurately time, temperature and
pressure can be controlled, the more consistent and close to
perfection will be the MULTI LAYER laminates. In these new PHI
presses, these parameters...time, temperature and pressure...can be
precisely controlled with exceptional accuracy and repeatability.
Press operation is far smoother and quieter, and the array of
controlling, monitoring, and readout components include the most
advanced, sensitive and reliable instruments available.
 STEAM
HEATED PLATENS
Steam heated presses are supplied as standard with
steam temperature controller, by-pass valves, steam traps, inlet and
outlet manifolds and all components required for a complete system.
Controller includes proportional band adjustment plus
automatic reset and will control each platen to within ± 4 º of
desired set point in an area one inch in form the platen outer
periphery.
Digital display of platen temperature is included to
monitor individual platen temperature or all platen temperatures
automatically in a scanning mode, as selected by operator.
OIL HEATED PLATENS
Presses are similar in characteristics to steam heated
platens except higher temperatures can be reached and better
temperature uniformity during cooling can be obtained.
PHI can supply also the hot oil unit and thus, assure
system performance. Please contact PHI for
specifications. |
