Threaded Limit Type Cartridge Heater Single Head Heater

Basic Info.

• Structure: there is a round or plate type stop plate welded on that terminal part of the limit type cartridge heater. 

• Application: Mainly applicable to mold or machine equipment, the heating hole is used as the through-hole so that the limit element can generate longitudinal displacement. 

• General operating voltage: 6~440V

• Recommended specification: 10~20mm× 60~1000mm.







Illustration of how to judge the electric heating element’s rated power:

1). 2.5V/1W light bulb C is connected in series with the electric heating element A at 220V;

2). 2.5V/1W light bulb D is connected in series with the electric heating element B at 220V.

Compare the brightness of the two light bulbs, if that C lamp is bright, indicating that the voltage across the C lamp is great, the current in the circuit is larger than in the second case, the resistance of the electric heating tube A is small than that of the B, so that the power of A is greater.




Formula for calculating wattage of limit type cartridge heater:

8 x p x l ( cm ) × w / cm2 = w ( total power per glow bar )

( pi = 3.1416 ) ( l = length of heating section ) w / cm2 ( watt density ) = normal 8 w / cm2

Customers can customize high watt density heaters ( 8 w / cm2 or more ) according to actual needs.

Threaded limit type cartridge heater using precautions:

       1. the limit type stainless steel itself is equipped with high watt density, due to the poor heat transfer, usually cause the external tube blackened, internal high temperature accelerated electric hot wire aging, lead to electric hot wire fracture.

       2. the mold deep hole processing should pay attention to the accuracy, not two drilling, because the junction can't close and have larger pores, make the electric heating tube heat radiation is bad, the heated body temperature is not average.

       3. attention should be paid to the magnesium oxide powder at the outlet end of the electric heating tube, in the use of place can not be contaminated with water infiltration to prevent leakage, it is best to reserve 5 m / m outside the mold.




General Applications:

       Limit type stainless steel single head electric heating tube high watt, small size, multi - specification, high temperature, high accuracy of outer diameter, easy to heat the mold. Conventional limit stainless steel single-head electric heating tube is suitable for: plastic packaging, small mold heating, analytical instruments, cigarette industry, manufacturing, semiconductor eutectic welding, die casting inlet heating and no glue injection, all kinds of gas expansion cooling effect of heating.
