HD Heater

The cartridge heater is a versatile and durable product used to heat everything from heavy industry -- plastics and packaging -- to critical medical equipment and analytical testing instruments, to airplanes, trains and trucks.HD Heater

The cartridge heater can operate at temperatures up to 750°c and achieve a watt density of up to 30 watts per square centimeter.HD Heater

From stock or custom manufactured to your personal application needs, they come in many different imperial and metric diameters and lengths with many different style terminals, wattage and rated voltages.

In the plastics industry, box heaters are a good solution for injection, blowing, and extrusion molding.

High temperature resistance (maximum 1500f), vibration resistance.

The cartridge heater is inserted into the mold to heat a large area of the surface.

Aluminum and steel molds are common because they are cheap and dissipate heat quickly.

Box heater has high precision.

They are usually used to seal plastic bags.

Accurate heating is necessary because the temperature must be high enough to seal the bag, but not high enough to melt the plastic.HD Heater

Tips for Cartridge Heaters How to Prolong Life Time:

1. Do not exceed recommended maximum watt density specified for

the cartridge heater size.

2. The tubular heater sheath must fit properly into the machined hole. A tight fit

is critical.

3. Protect the tubular heater from contaminants such as oil, grease, and vapors.

4. Install adequate Kw to accomplish work load and make up for heat losses.
