Mold Temperature Controller

Mold Temperature Controller (YBMI/YBMD)

Our temperature control unit can use water/oil heating system to secure the high quality of plastic products made by injection, extrusion and blow molding machines. 

FEATURES

How to Choose Model

  • YBMI series are ideal for oil: By oil, suit for long-term continuous operation, keep the temperature steady, no flash on tiny and thin products, and no corrosion. However, the heater may be damaged if you do not use the thermo oil correctly or change oil routinely.Recommend to choose oil-type mold temperature controller when your required temperature is 150℃ or above.

  • YBMD series are ideal for water: By water, heating up faster, cooling better, harmless to your mold   and more economic than oil type for maintenance and cost. However, the water boiling point is low and the element of different water may occur corrosion or limescale to affect the heat exchange and products quality. Recommend to choose water-type mold temperature controller when your required temperature is 150℃ or below.

To improve the efficiency :

  • Automatically controls of mold temperature to give perfect moldings with every shot.

  • Keep mold at correct temperature even when machine is stopped thus eliminating start up delays in the morning or during daytime stops.

  • As mold temperature is kept at its optimized temperature, the injection molding machine can run at its maximum speed to suit the job.

To improve the quality :

  • Steady controlled temperature makes plastic molding accurate in size and consistent with quality.

  • Accurate mold temperature solves the problem of plastic flow patterns, reducing flow and weld lines, gloss appearance, record grooves effect, silver streaking, stress-whitening, warping, and etc....

Structure features :

  • Water/oil dual purpose design can use either water or oil as heating media.

  • Special compact construction means both heating and cooling of the medium being used is done within the unit. (Exclude the model with a vertical pump)

  • PID temperature controllers are used for accurate control of temperature within±1℃.

  • Two-step-heating selector makes rapid temperature increasing possible when require thus saving time and power specially start up in the morning.

  • The stainless steel tank guards against corrosion to ensure leak-free and long-lasting.

  • Well thought of safety devices such as alarms for errors, circuit breakers, motor direction, overheat protector, auto-exhauster, and etc...

FAQ

Mold Temperature Controller

    1. The tooling / mold pipe lines are plugged, cause the pipeline deposit excessive carbon and block the pipe filter.

    2. Improper select wrong mold temperature controller that not meet customer needs.

    3. Lack of flow & electricity.

    4. Find the fault of heating element, contactor, temperature controller.

    1. Find the stuff like as iron filing that stay inside of pipeline to cause the leaking oil.

    2. Improper or over usage this unit standard range.

    1. Check the tank shall have sufficient water. 

    2. Connect correct of cooling water inlet and outlet. 

    3. Check whether plugged of cooler.

    4. Check error of solenoid valve or temperature controller.

    5. Regularly clean or replace the filter.

  • Check the pressure if there is no or insufficient to cause the water flow is short of water outlet to mold.

    1. Happen this condition by mixing with oil and water and then heating. Suggest to replace new kerosene (oil) and clean the pipeline. (Be careful to check the water vapor inside of wheel.

    2. If air left in the pipeline to cause the kerosene emitted and even burned out the heating element.

  • Malfunction of cooling fan, temperature controller, buzzer or indicator light leaking electricity to cause the fuse burned out.

    1. Find no loop or block or lack of kerosene (oil).

    2. Excessive deposition of carbon to cause heating element smoldering. 

    3. Error of EGO (overheat preventer), spot welding death of contactor, malfunction of temperature controller.

  • Molding machine of user is unable in operation, because from the leakage electricity of pump and heating element.

    1. The temperature wave large. (ex. easy to reach 150℃ and down to 130℃)

    2. Inside with vapor. (mixing with oil and water, visual recognition finds the oil muddy or not.)

    3. When find the water inside must be drawn to all of the oil, and then refilled with new oil.

    4. Be attention of heating element when you refilling new oil to prevent the smoldering of heating element.

    5. If your roller machine is high speed rotation about 500 RPM, 20 ~30 RPM per minute will cause the centrifugal and the oil will not be able to fully send out.  Please couple with outside with friction pump to drawn the oil from the inlet of mold temperature controller.

Chiller

  • Temperature controller or thermocouple is faulty. Or Temperature controller does not match up with correct thermocouple. (112 matches up with Light Blue wiring of Thermocouple, and 901 matches up with Light Blue or Gray thermocouple. 902 and 902plus match up with Gray thermocouple.)

  • Check if Cooling fan is damaged, Filter net is stocked, Condenser is stocked, there is no cooling water, or the water pressure is not high enough.

  • Cooling is too well to lead Low pressure protector triggered, please turn cooling water less and decrease the radiations (for Air model). Or there is refrigerant leakage inside piping of unit.

    1. Setting temperature is too low to lead huge differences for overheat protector or damaged.
      ( Setting temperature lower than 5℃ )
      Please change temperature to set at 7~8℃, and reset again after temperature is working normal.

    2. Stopped supplying cooling water to unit would lead Evaporator frosted.
      Please defrost it for 24 hours to reuse it.

  • Reason:
    Low temperature of Environment leads unit working better, but sometimes it would lead Low pressure protector triggered.

    ​

    Ans.:

    1. Please turn cooling water less. (to make water circulation not so good)

    2. Adjust Low pressure switch lower than 1kg/cm².
      This is because cooling water is low, and it would make it much lower to lead Low pressure protector triggered. 
      ( Especially Environment Temperature is about 12℃ or lower)

    1. Non-stop working for Compressor for a certain period of time.
      (Compressor keeps working because of unable to reach required temperature from its setting.)

    2. There is water inside Compressor. (Piping damaged and lead water going inside compressor.)

    3. High pressure and Low pressure does not stay at stable value inside Rated range.
