Injection mold heater is designed to clamp for internal use or external use of the cylindrical surface. Our heater bands for injection molding are designed to heat up to high watts and crazy high temperatures or can stay just slightly warm, whatever your preference. The most common use for a heater band is for injection molding, molding presses, pipe heating, heating treatment, along with the food industry and more. Our heaters have three ways to transform heat. These include conduction, convection, and radiance.
- Conduction moves the heat by direct contact. Our best example of this is when you heat up the end of a metal rod. When doing this you can see the end is flaming hot and has a red tone to it. But looking down the pole to you it starts to cool down. This shows you that over time heat travels through certain material. This is called thermal conductivity which is the amount of mass available to handle the amount of heat energy. This is one way they use heaters for injection molding.
- Convection currents are the example that heat rises. How to explain this is by looking at water and adding heat. Which ends up making the volume of the water expand and rise. The last stage of the molding the end material is called condensation which is water in a vapor form.
- Radiance is the process of having heat but without direct contact with an object or thing. This form of heat travels in waves and a good example of this is the sun. The best way to absorb the heat is at night or in a dark location.
How the Injection Mold Heater Works
The injection mold heater needs to have a power supply. Then you find the power button which fires up the heater inside. Which starts heating up the machine slowly. There other knobs and switches on your machine to control how much heat the heater gives off. This helps with being able to have the right temperature to do your molds in. Our heaters are the best you can find here in America so buy one and try it out for yourself and they are made right here in the United States.
What are Heater Bands for Injection Molding?
Injection molding is the process of making multiple things at once using meltable materials. Our heater bands for injection molding heat the material you put into the machine at the injection mold machine level. We also have heaters that can be inserted into the various dies as well. It is important to have backup Injection molding heaters so the repair can be done quickly and production is interrupted as little as possible. Engineers around the U.S love this way of making products because it is fast and simple. Injection-molded parts are literally everywhere in this world. If you have an injection molding machine that needs a replacement heater, give us a call.
Injection molding is a very fast way of producing a lot of like parts over and over again. Typically it requires very little manpower to keep the processes going. When you are working around in injection molding matching you will notice various types of heater designs as well. There are insert heaters, band heaters, nozzle heaters and so much more. The idea is to get the material heated to the temperature needed to produce molded parts. But, the heat must be even, to avoid scorching the materials. The movement of the machine combined with the heaters will give this perfect balance.
Overview of Our Heater Bands
When looking at heaters for injection molding you can see there are all kinds of reasons for them to be needed in the industrial world. Injection molding has three ways heaters work which is convection, conduction, and radiance. We offer each of these kinds of heaters for your injection molding needs.
