Plastic film heat sealing tester characteristic:
Plastic film heat sealing tester is based on the test method of hot sealing, and adopts the hot head designed according to the national and international standards. It is specially used to measure the key parameters such as heat sealing temperature, heat sealing time and heat sealing pressure of various heat sealing composite films, so as to guide large-scale industrial production.
1. Digital p.i.d temperature control technology can not only quickly achieve the set temperature, but also effectively avoid temperature fluctuations
2. Wide range of temperature, pressure and time control can meet the user's various test conditions
3. Manual and pedal start-up mode and anti * * safety design can effectively ensure the convenience and safety of users
4. The precision mechanical design is adopted. The aluminum can sealing hot head ensures the heating uniformity of the hot surface, and the cylinder controlled lifting of the hot head evenly pressurizes the hot surface
5. The design of lower cylinder can not only ensure the stability of the instrument in operation, but also effectively avoid the pressure fluctuation caused by heating
6. The upper and lower hot heads can control temperature independently, which provides more combination of test conditions for users
7. The bottom type double cylinder synchronous circuit further ensures the pressure uniformity of the hot surface
8. The lengthened heat cover can be used to seal large area samples or multiple samples at the same time, and support the customization of various heat cover forms
9. Equipped with foot switch to ensure safe operation of users
10. The pneumatic control element has high precision, and the whole set adopts international famous brand
11. Anti scald design and leakage protection design, safer operation
12. The heating elements are well designed, with uniform heat dissipation and long service life
13. According to the principle of ergonomics, the operation panel is specially optimized and designed, and the operation is convenient


Plastic film heat sealing tester Operation use:
1. Connect the compressed air pipe to the compressed air inlet on the left side of the instrument;
2. Connect the foot switch to the connection on the left side of the instrument;
3. Connect the power cord socket to the power inlet on the left side of the instrument;
4. Preparation of test materials;
5. Pass in the compressed air and adjust the pressure to the pressure value that can make the upper and lower heat sealing knives press together, usually 0.18-0.30 MPa;
6. Turn on the power switch on the left side panel;
7. Turn the heating switches of the upper heat sealing knife 12 and the lower heat sealing knife 11 to on;
8. The temperature controller is set to the required temperature. The recommended values of heat sealing temperature of common film materials are shown in the attached table
9. It takes about 10-30 minutes to stabilize the set temperature;
10. Set the timer to the required time, i.e. heat sealing time;
11. After the above operation is completed, adjust the working mode switch to automatic or manual as required, and the heat sealing instrument can conduct heat sealing according to the set time.
