Electromagnetic induction heating technology is to make the metal barrel of the injection molding machine heat itself, and wrap a certain amount of heat insulation material on the outside of the barrel according to the specific situation, which greatly reduces the heat loss and improves the thermal efficiency, which can reach more than 96%. Therefore, the power saving effect is very significant, which can reach more than 30%, and the heating speed is increased by 60%, which greatly saves the preheating time.
Advantages of high-frequency electromagnetic induction heater products
Long life: Electromagnetic induction heating has a long life because the coil itself basically does not generate heat, no maintenance is required, and no maintenance replacement cost; the heating part adopts a ring cable structure, the cable itself does not generate heat, and can withstand high temperatures above 500 degrees, with a service life of up to 10 years. No maintenance is required, and there is basically no maintenance cost in the later stage.
Safe and reliable: The outer wall of the barrel is heated by high-frequency electromagnetic action, and the heat is fully utilized and basically not lost. The heat is concentrated inside the heating body, and the surface temperature of the electromagnetic coil is slightly higher than the room temperature. It can be safely touched, without high temperature protection, safe and reliable.
High efficiency and energy saving: Induction heating is adopted, and some molecules in the heating body directly induce magnetic energy to generate heat. The hot start is very fast, and the average preheating time is shortened by more than 60% compared with the resistance coil heating method. At the same time, the thermal efficiency is as high as more than 90%. Under the same conditions, it saves 30-70% of electricity compared with the resistance coil heating, which greatly improves the production efficiency.
Accurate temperature control: The coil itself does not generate heat, has small thermal retardation and low thermal inertia, and the temperature of the inner and outer walls of the barrel is consistent. The temperature control is real-time and accurate, which significantly improves the product quality and has high production efficiency.
Good insulation: The electromagnetic coil is wound with a customized special high temperature and high pressure resistant special cable wire, with good insulation performance, no need to directly contact the outer wall of the tank, no leakage, short circuit fault, and safe.
Improve the working environment: The injection molding machine modified by electromagnetic induction heating equipment adopts the internal heating method, and the heat is concentrated inside the heating body, and there is almost no external heat dissipation. The surface temperature of the equipment can be improved to a level that can be touched by the human body, and the ambient temperature is reduced from more than 100°C when the original resistance coil is heated to room temperature, which greatly improves the working environment of the production site, effectively improves the enthusiasm of production workers, and reduces the ventilation and cooling costs of the factory in summer. Based on the concept of "people-oriented", we create an environmentally friendly, safe and comfortable production environment for factories and front-line production personnel.
Application range of electromagnetic induction heater
1. Plastic and rubber industry: such as plastic film blowing machine, wire drawing machine, injection molding machine, material making machine, vulcanizer, extruder, etc.
2. Pharmaceutical and chemical industry: such as pharmaceutical infusion bags, plastic equipment production lines, liquid heating and delivery pipelines in the chemical industry, etc.
3. Energy and food industry: such as crude oil pipeline heating, food machinery such as supermarket cargo planes, etc. require electric heating equipment
4. Boiler industry: electromagnetic boilers use their fast heating speed to abandon the traditional boiler overall heating method and only heat at the water outlet of the boiler, so that the water flow is heated in the flow, the heating speed is fast, and space is saved
5. Textile printing and dyeing: electromagnetic heating of raw materials can improve energy utilization efficiency, increase heating speed, and improve temperature control accuracy; light industry canned and other plastic packaging sealing, etc.
