Typical Packaging Sealing Application Thermal Challenges

  • Calculating Energy Requirements
  • Different Technologies Available
  • Electric Heat Wattage Requirements
  • RTD And TC Placement(s)
  • What Type Of Material To Use
  • Sealing Lengths Can Be Exceptionally Long
  • Multi Piece Tools
  • Electric Heater Designs Are Not Utilizing Distributed Wattage
  • Non Sealed Spots
  • Thermocouple Designs Are Inadequate
  • Non Isothermal Conditions
  • Premature Electric Heater Failure

Taking A Look At Hot, Cold, & Non-Sealed Spots

One starting point you want to review when utilizing electric heaters, such as cartridge heaters, is the heater designed correctly for your application. Ensure that your supplier is knowledgeable enough to design distributed wattage cartridge heaters instead of standard ones. If you are looking for more information on what a distributed wattage cartridge heater is and how it can help in your application contact one of our engineers today.

  • Using the example of a seal bar or jaw to discuss hot and cold spot challenges, most of these issues can be solved by taking a thermal solution approach.
  • One great trick to obtain uniform temperatures is to implement an Acrolab Isobar into the sealing bar. It is always best to implement the Isobar as close to the sealing surface as possible. This way you give the thermal energy time to become isothermal as it travels from the heater through the Isobar to the working surface.

Multi-Piece Tools And Obtaining Temperature Uniformity

  • Thermal challenges grow exponentially once you start having multiple tool pieces that are bolted together. Typically a cal rod or tubular heater will be used in some applications.  A slot will be milled in two plates and the heater will be sandwiched in between these plates.  This process can occur more than once in a single tool.  The issue with doing this is thermal breaks are created every time a new piece of a tool is introduced.  This results in large temperature drops.
  • The way to tackle multi-piece tooling is to implement distributed wattage heaters as mentioned. Also, ensure that your two pieces are in intimate contact with each other. This can be achieved by calling out for a very smooth machined surface.  An Isobar heat pipe should be used either next to the heater, in between them or close to the working surface to assist with moving thermal energy.
