MOLD TEMPERATURE CONTROLLER
PRODUCT OVERVIEW MOLD TEMPERATURE CONTROLLER
■ Necessity and Features of PID Control Temperature Controller In order to secure and stabilize the quality of molded products, it is necessary to have a control function that keeps the temperature as constant and stable as possible, while suppressing the range of the upper and lower temperatures compared to the mold set temperature. This controller eliminates the difficulty of temperature control for molds using heaters by adopting the PID control method. • PID (Proportional, Integral, Derivative) control method. ( ※ 1) • Suitable for high–precision moldings that are easily affected by variations in mold temperature and for moldings that require strict mold temperature control. • Unlike the conventional ON/OFF control method ( ※ 2), variations in mold temperature can be suppressed. < Differences in temperature control with respect to set temperature >

※ 1 What is PID control? PID control is a control method that minimizes the range of variation in temperature rise and fall relative to the set temperature of the mold. In addition, by combining the PID function and SSR (semiconductor relay), this controller automatically adjusts the power supply to the heater by the PID control function and improves the accuracy to the set temperature. → Refer Fig. 1 E A slight variation in temperature may occur depending on the position of the temperature sensor and heater. ※ 2 What is ON / OFF control? It is a function to control the set value up or down (switch OFF when the temperature rises above a certain level, and switch ON repeatedly when it falls below a certain level) in relation to the set temperature of the mold. The range of variation in relation to the set temperature varies depending on the thermal balance between the heater and the mold, but a larger variation is generated than with PID control. → Refer Fig. 2

■ Precautions for use (1) Please use it for temperature control of injection molds. We are not responsible for any other use. (2) Please do not use it with a power supply voltage other than indicated, because it may cause fire, electric shock, or the breakdown. (3) P lease do not connect the heater exceeding the maximum capacity. There is a possibility that the electric parts in the temperature controller will fail. (4) N ever modify the existing wiring inside this controller box. (5) Turn off the power when connecting the sensor and wiring the input and output. (6) U se the specified type of sensor, and tighten the connections securely. (7) Securely tighten the connection of the input/output wire with the crimp terminal. (8) If the cable of the heater and sensor is damaged by the opening and closing of the mold of the molding machine, the electric part in the temperature control controller may be damaged, so be careful when routing the cables. (9) D o not use in a flammable gas atmosphere. Doing so may cause an explosion or fire. (10) D o not operate the product with wet hands. It may cause electric shock. (11) D o not allow water to splash on the controller. Use of the controller as is may result in electric shock, leakage of electricity, or malfunction. (12) A qualified person should perform the connection and wiring to the controller. (13) It is recommended that the clearance between the plate hole and the heater is 0.05 or less per side. If the clearance is too large, a short circuit or other problem may occur in the controller due to abnormal heat generation.
