PTC self-
controlled heater

PTC heater, the temperature can be controlled itself

Long life, temperature controller and protector are needless

Temperature rising is slower, temperature can not be adjusted

Used in small ones

PTC heater, with a controlled circuit

PTC with higher temperature, but control the  temperature lower by a circuit

Long life,
temperature protecting can be neglected

Temperature control is needed, temperature rising is slower

Used in small ones or big ones

Ceramic heating plate

Coating a heating layer and an insulating layer on ceramic plate

Temperature rising is faster, simple to be assembled

Temperature control and protect are needed, higher cost

Used in big ones

 

Notice for manufacturer and consumer:

     The temperature on surface of press plate is controlled between 140~180℃.
The press plate usually coated with a teflon layer or other layer from adhesion between film and pressing bar.
     For a film covering machine that can press A4 paper or little, the power is about 50~100W without pressing; and 150~300W with pressing。
     One PTC heating element can be applied on 100V~230V, the temperature difference would be about 10℃.
