HSM-4 Laboratory Heat Sealer

The HSM-4 Laboratory Heat Sealer was developed to precisely control the parameters essential in determining the heat seal threshold.
Especially suited for flexible packaging materials, laminates, foils, and paper. The HSM-4 features accurate control of temperature, pressure and dwell time of a standard surface area sealing jaw.

This Heat Sealer is used for precise control of heat sealing process variables (temperature, pressure, and dwell time), enables an optimal balance of material specification, packaging machine speed, and seal integrity. Accuracy and repeatability in laboratory heat seal testing is vital, and the HSM-4 provides a standard range of controls for this purpose.

With features like:

  • Pressure calibration of standard surface area jaw face
  • Temperature digital controller, pressure and dwell time dial controllersHSM-4 Laboratory Heat Sealer
  • Jaws constructed in aluminum and silicon with precision ground faces
  • Range of jaw face surfaces including Matched Crimp and Teflon Coating
