Leading Instruments Co Ltd / HST_01 Heat Seal Tester



HST_01 Heat Seal Tester
               HST_01 Heat Seal Tester seals the specimen to determine the seal parameters of basic film, laminated films, coating paper and other heat sealing laminated films according to the requirement of relative standards. The seal parameters include heat seal temperature, dwell time, and the pressure of heat seal. Heat seal materials that have different melting point, heat stability, fluidness, and thickness of could show various heat seal properties, which cause obviously different seal technique.
  • P.I.D. for precise sealing temperature control
  • Uniform heating by aluminum encapsulated sealing jaws and no inhomogeneous heating
  • Multiple groups of test parameters can be saved to reduce setting time and eliminate human error
  • Independent heating of upper and lower sealing jaws on the model of Heat Seal Tester.
  • Sealing jaw customization available in term of dimension, shape and surface
  • Seal Temperature: room temperature~300ºC
  • Temperature Control Accuracy: ±0.2ºC
  • Dwell Time: 0.1s~9999s
  • Dwell Pressure: 0.15MPa~0.7MPa
  • Seal Surface: 330 mm x 10 mm (Sealing Surface)(Customization Available)
  • Heat Type: Double heat surface
  • Gas Source Pressure: 0.5MPa~0.7Mpa (Users prepare gas source themselves)
  • Gas Source Inlet: 6mm polyurethane pipe
  • Power: AC 220V 50Hz
