Principle
HST-H3 Heat Seal Tester is composed of upper and lower heat sealing jaws. Before the test, preset the heat seal temperature, pressure and dwell time value, place the specimen in between the upper and lower jaws, and then press start button. The whole sealing process can be finished automatically.
Standards
This test instrument conforms to the following standards:
ASTM F2029, QB/T 2358, YBB 00122003
HST-H3 Heat Seal Tester is applicable to the determination of heatsealability of:
| Basic Applications | Films with Smooth Surface
Including plastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many others. Heat sealing surface should be smooth and width can be designed based on user requirements. |
|---|
Films with Decorative Pattern Surface
Including plastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many others. Heat sealing surface can be designed based on user requirements. |
| Extended Applications | Covers of Jelly Cups
The instrument is composed of the upper and lower jaws. The upper one is round-shape while the lower one is designed as a specimen mould whose size exactly fits the jelly cup. Put the jelly cup in the mould of lower jaw, and heat seal can be finished by upper jaw pushing. (Customization required) |
|---|
Plastic Flexible Tubes
The ends of plastic flexible tubes are placed in between upper and lower jaws and then sealed to form a package. |
Professional
HST-H3 Heat Seal Tester is based on the heat sealing method, and is professionally applicable to the determination of heat seal temperature, dwell time, and the pressure of various composite films to guide industrial production. The instrument adopts the specially designed heat sealing jaws, which completely conform to multiple national and international standards.
Digital P.I.D. temperature control technology ensures the preset temperature to be reached rapidly without any fluctuationWide range control of temperature, pressure and time that meet various test conditionsManual or pedal switch, as well as anti-scald design provides convenient and safe operating environmentThe instrument is controlled by micro-computer with LCD, PVC operation panel and menu interfaceProfessional software supports remote operation for convenient data saving, exporting, and printingPrecision
HST-H3 Heat Seal Tester utilizes precision mechanical structure design. The aluminum-encapsulated heat sealing jaws ensure uniform heat spreading along the sealing surface; cylinder-controlled sealing jaws equally apply pressure upon test specimens; rapidly removable heating tube joints provide convenient operation.
Aluminum-encapsulated sealing jaws provide even and uniform temperature for different sealing surfacesDual underneath type of gas cylinders ensure stable pressure during the test processThe heating tube joints can be easily installed or removed for rapid replacementHigh-end
HST-H3 Heat Seal Tester is designed based on the HST-H6 with more intelligent functions, which is the best choice for high-end users.
Independent temperature control of the upper and lower jaws gives multiple combinations of test conditionsDual underneath and closed loop-type of gas cylinders ensure even pressure of sealing surfaceExtended sealing surface can seal large or several specimens at the same timeEquipped with pedal switch for safe test operationStandard RS232 port and professional software facilitate to connect with computer and data transfer
