Temperature Uniformity Solved: Isobar® Heat Pipes Work In Both Heating And Cooling Applications

Thermal uniformity issues are a big problem with many rubber tooling applications.  Weather you are utilizing heated platens or heating your tools directly, thermal uniformity is a concern.

  • One solution is to implement Isobar heat pipes into the tool.
  • Acrolab Isobars or heat pipes can either be implemented for heating or cooling issues.
  • Isobar heat pipes move heat 250 times faster than copper they are an easy choice to remedy any thermal uniformity issues.
  • This solution also dramatically helps with thermal recovery during faster cycle times

Dealing With Multiple Inserts

Due to the complex part geometries, it is not uncommon to have multiple inserts within a tool. Every insert that is added to a tool presents an additional challenge for thermal transfer. The best practice to take is to implement a heat source or Isobar heat pipe into the insert.  The goal is to bridge the thermal break between the tool and the insert.  By doing this you will eliminate potential thermal recovery issues that can typically occur.

  • If it is possible to taper the insert to the tool this would be highly recommended. By tapering the insert to the tool you create the maximum surface contact to ensure optimal thermal transfer.
  • It is also important to machine the two mating surfaces as smooth as possible.  This will ensure you have intimate contact between the tool and insert
