2 StackPulse Controller The SPC - StackPulse Controller is the newest addition to the PulseCooling in process temperature controls. The SPC has embedded microchip technology for compactness, longevity and high performance. DESCRIPTION OF StackPulse Controller The StackPulse Controller controls the mold surface, not just the water line. Now you can have a Real Time read out and direct precision control of the mold surface temperature. PRINCIPLE OF OPERATION As heat is induced into the mold, with the melt, at the start of the cycle, the temperature increase of the mold surface is detected by a sensor and stored for reference in the StackPulse Controller. The microprocessor converts this into a cooling pulse, which is a timed injection of coolant, occurring at the beginning of each cycle, immediately after the mold has been filled. The coolant injection (-BTU) exactly matches the melt (+BTU) thus compensating for all variables that can influence part quality. This cooling technology will results in the highest quality parts quality at the best possible cycle time with a minimum of water consumption and energy use. Remember, high quality molding is the result of what happens in the machine and the mold, not in the inspection after the molding is completed. ADVANTAGES OF PULSE MODULATED COOLING INCREASED PRODUCTION Use of cold water provides a high temperature differential between mold surface and coolant. This high delta t results in efficient mold cooling with a improved cycle. HIGHER QUALITY PRODUCTION During the OFF period of the pulse modulated cooling cycle, the mold will seek thermal equilibrium. This heat gradient dissipation results in consistent quality molded parts. AUTOMATED PRODUCTION After the operator chooses and sets the mold surface temperature, the StackPulse Controller will determine the cooling requirements of each molding cycle, and automatically repeat the selected temperature. Each cooling pulse will compensate changes in cycle time, melt temperature, cycle interruption, water pressure, ambient temperature and platen temperatures changes. PROCESS LIMITS WARNING A visual alarm warns if the process temperature is above or below the selected limits. COOLING FLUID SOURCE The StackPulse Controller valve is supplied with cold process water from tap, tower or chiller. WATER CONSUMPTION A Minimum amount of water is used; since the maximum of BTU is absorbed from the cold process water, and during the off pulse period the dormant water will absorb heat. This reduces the total amount of water used. Thus more Process water is available for the area with the greatest demand of cooling. ADVANCED FEATURES Additional features such as maximum and minimum temperature alarms can be displayed. The measured values can be displayed in either English or Metric units. All selections are done digitally on the keyboard. 2

7 Mold Connection Diagrams To obtain the highest performance from you StackPulse Controller the sensor should be placed close to the molding part. Three Zones Parallel - Series Connection 120F 120F 110F Advantages: Direct control of movable, stationary and hot runner. RETURN SUPPLY 120 VAC FOR ZONE 1 AND 2 USE DUAL OUTLET END CAP Highest reynolds number obtained Three Zones Series Connection MOVABLE STATIONARY Advantages: Low water consumption One supply and Return per mold half. Direct control of movable, stationary and hot runner. 120F 120F 110F 120 VAC Apply when limited cooling water is available RETURN SUPPLY This will minimize the pressure drop on the water supply thus maintain a higher flow velocity thus cool efficiently.
