Why use a mould induction heating machine?
At present, mould heating adopts an ordinary electric heating oil bath oven. Its main principle is to heat the mould through heat radiation of the oven wall and heat exchange between hot air and mould. The conventional electric heating oil bath oven has the disadvantages of the long heating cycle, low heating efficiency, high requirements for operators’ experience and high energy consumption. As a new heating technology, mould induction heating machine has the characteristics of precise heating depth and heating area, high heating power, fast heating speed, high efficiency, low energy consumption, easy to control of the heating temperature, ease to realize the heating process automation.
Since the 1930s, mould induction heating technology has been widely used in industrial production, and so far in many industrial fields has shown more and more extensive application prospects.
At the same time, mould induction heating machine investment cost is low, especially accurate temperature control, its application in the powder temperature pressing moulding process, will greatly improve the quality and production efficiency of moulding products.
How to do mould induction heating?
Special equipment for three-station mould induction heating and preheating machine: Continuous induction heating, preheating one mold every 60 seconds or so, Mould induction preheating is heated by temperature closed-loop control by three-station integrated intelligent mould induction heating equipment, and the mould is preheated to 150℃ for assembly. The temperature difference between the mold’s outer wall and the inner wall is small, and the overshoot tendency of the internal temperature of the mold is reduced. The temperature in the heating process is stable and easy to control, improving production efficiency and product quality.
What is mould induction heating machine features?
- Adopt induction heating preheating method: high efficiency, fast preheating speed, multi-stage temperature control in preheating area, uniform preheating temperature, no oxidation phenomenon;
- The second-generation DSP intelligent mould induction heating machine is adopted, with power and temperature double closed-loop control mode. At the same time, it can realize the temperature curve control function, 4-point temperature display, and protection function. During the heating process, the overall temperature of the mold does not exceed the set temperature ±3°C; the temperature difference between each part of the mold is less than 5°C at the end of the heating; the heating power is adjustable, and the feedback adjustment can be performed according to the actual temperature of the mold, and the heat preservation function can be realized.
- The online thermocouple closed-loop control system has high temperature control accuracy, fast control speed, and real-time temperature display and record.
- With real-time temperature alarm function, the production line beat abnormal situations with timely alarm signals, including high and low temperature alarms, heating timeout alarms, etc.
- Professional online tooling positioning fixtures ensure accurate positioning of each mold when heating, ensure temperature uniformity and preheat speed.
- It has the functions of constant power, constant current, and constant temperature switching and combination, which is convenient for heating applications with different loads.
- With remote control and internal control operation mode switch, convenient control mode switch.
- It has remote control and internal control operation mode switching, which is convenient for control mode switching.
- With the function of load matching indication, it is convenient and intuitive to guide the selection of load matching.
- With the equipment alarm status recording function, it is convenient to query equipment historical data.
- It has the function of hierarchical login for administrators and operators to prevent unauthorized personnel from adjusting the heating process.
- Intelligent DSP mould induction heating machine operation status and parameters such as voltage, current, power, frequency, etc. are collected and monitored in real time. At the same time, these states can be directly connected to the centralized control network through the internal communication interface of the power supply, and the required parameters can be transmitted to other controllers such as industrial computers, numerical control systems, notebook computers, remote control centers, etc. to achieve the needs of the Internet of Things in the workshop.
