PULSECOOLING: OPTIMIZING EVERY MOLDING CYCLE
FOR HIGH PERFORMANCE

THE SMARTER WAY TO CONTROL YOUR PROCESS

PulseCooling senses the mold temperature and applies a pulse of coolant at maximum flow rate directly from the chiller or cooling tower during each molding cycle for maximum heat removal. Each cooling pulse equals the excess heat from each molding cycle and compensates for cycle time, melt and ambient temperature and coolant pressure changes (flow).

CONVENTIONAL COOLING VS PULSECOOLING TECHNOLOGY

Conventional Cooling vs PulseCooling Technology
STILL COOLING WITH WARM WATER?
WHY??

Continuous Flow Mold Temperature Control Systems

NO DIRECT CONTROL OVER MOLD SURFACE TEMPERATURE

Conventional Cooling vs PulseCooling Technology

Continuous flow control adjustments are ALWAYS RETROACTIVE in response to visual/dimentional changes in the parts.
YOU ARE THE CONTROLLER - 24/7

DOES NOT COMPENSATE FOR:

  • Ambient temperature changes
  • Water temperature changes
  • Water supply pressure changes
  • Back pressure changes
  • Cycle changes
  • Platen and machine temperature changes
  • Day and night shift changes
  • Partial plant shut down
  • Over cooling during cycle interruptions
  • Part geometry vs. cooling channel layout
  • Melt temperature variation

RESULTING IN:

  • Inconsistent mold temperature rise (heat exchange)
  • Poor mold fill - from the Continuously forced temperature gradient the melt front will resists mold fill during injection
  • Inconsistent part quality - from uncontrolled variables
  • Mold temperature drift over time - machine and ambient temperature variations
  • Heated water slows heat removal - Longer cycles
  • UNPREDICTIBLE PARTS AFTER EJECTION

PULSECOOLING HAS ECLIPSED THE STATUS QUO!

YOU NOW HAVE CONTROL OVER MOLD SURFACE TEMPERATURE

Conventional Cooling vs PulseCooling Technology

THE PULSECOOLING CONTROLLER AUTOMATICALLY MAKES PRO-ACTIVE ADJUSTMENTS TO MAINTAIN MOLD SURFACE TEMPERATURE

COMPENSATING FOR:

  • Ambient temperature changes
  • Water temperature changes
  • Water supply pressure changes
  • Back pressure changes
  • Cycle changes
  • Platen and machine temperature changes
  • Day and night shift changes
  • Partial plant shut down

RESULTING IN:

  • Consistent mold temperature profile 24/7
  • Increased heat exchange
  • Excellent mold fill - No opposing resistance during injection
  • No uncontrolled temperature drift
  • Faster molding cycle - Efficient heat removal, very high delta t
  • CONSISTENT PART QUALITY - 24/7!

PULSECOOLING COMPENSATED FOR UN-MATCHED PART GEOMETRY AND COOLING LAYOUT

Beginning of the cycle a calculated pulse of water will match cooling requirement

Full flow - Full delta t

Turbulent flow for maximum heat removal

Note: minimum temperature rise between
“IN” and “OUT”

No flow - During cure time allowing the heat gradients to dissipate providing a more even and predictable environment for the next shot

PulseCooling thermal distribution across the mold

Between each cycle, each cavity/core seeks a thermal equilibrium resulting in:

BETTER CYCLE

  • Dramatically reduced stress in molded parts
  • Reduced (or eliminated) post ejection warping
  • Reduce mold hot-cold spots
  • Eliminates mold damage due to unchecked thermal expansion

SIMPLICITY

  • Minimizes (or eliminates) use of mold heaters
  • Clears up floor space around machines
  • Efficient mold water line hook-ups
  • Eliminates handling of hot molds, hoses, and fluids
  • Reduces (or eliminates) plugging of water lines in molds

EXCELLENT ROI

  • More precise and predictable parts 24/7
  • Increase production yield by 10-20%
  • Reduce energy consumption by 20,000 Kwh per year (minimum), per machine
  • Safer to use, and easy to learn
