The C630H from Labthink is a laboratory heat seal tester to determine optimal heat‑sealing parameters (dwell time, sealing pressure and sealing temperature) for plastic films, flexible composite films, plastic‑coated paper and other heat‑sealable materials. It reproduces production‑like sealing conditions through multiple sealing jaws and precise controls.
Product Features- Ten sealing jaws (five upper and five lower) with metal surfaces to obtain parameters close to actual production conditions.
- Digital PID temperature control for fast and stable attainment of set temperatures with minimal fluctuation.
- Automatic constant‑pressure technology to maintain stable sealing pressure without frequent manual adjustment.
- Auto‑leveling of sealing jaws for uniform sealing performance across samples.
- Wide control ranges for temperature, pressure and time to cover diverse test conditions.
- Manual or pedal start modes and anti‑scald design for safe operation.
- Professional software supporting remote operation, data saving, export and printing.
User‑oriented, efficient and safe design- Capable of completing tests on 5 specimen groups simultaneously to obtain sealing parameters efficiently.
- Independent temperature control for upper and lower jaws to meet different temperature combination requirements.
- Separated‑type sealing jaws for easy replacement and custom sealing widths.
- Manual and pedal switch options plus protective design to reduce burn risk during handling.
Embedded computer‑controlled system- Equipped with a large tablet (touch screen) for straightforward operation and observation during tests.
- User‑friendly software simplifies testing, supports group comparison analysis and unit conversion.
- USB ports and network interface for external device connection and data transmission.
- Optional GMP compliance; Labthink DataShield™ available for secure data management and instrument network integration.
Test Standards- ASTM F2029
- QB/T 2358
- YBB 00122003
Applications- Basic applications
- Films with smooth surface: plastic films, flexible composite films, paper‑plastic films, coextruded films, aluminized films, aluminum foils and aluminum‑foil composites. Sealing surface should be smooth; sealing width can be specified per user requirements.
- Films with decorative pattern surface: plastic and composite films where sealing surface or width may be adapted according to test needs.
- Extended applications
- Plastic flexible tubes: tube ends can be placed between upper and lower jaws and sealed to form packages.
