The DRK133 heat sealing tester uses the heat pressure sealing method to determine the heat sealing temperature, heat sealing time, heat sealing pressure and other parameters of plastic film substrates, flexible packaging composite films, coated paper and other heat sealing composite films. Heat-sealing materials with different melting points, thermal stability, fluidity and thickness will show different heat-sealing properties, and their sealing process parameters may vary greatly. DRK133 heat-sealing tester, through its standardized design and standardized operation, Accurate heat-sealing test indicators can be obtained to guide large-scale industrial production. Features Ø Microcomputer control, touch screen operation, menu-style interface. Ø Digital P.I.D. temperature control, under-mounted dual-cylinder synchronous circuit. Ø Two test start modes, manual and pedal. Ø Independent temperature control of upper and lower heat sealing heads, and a variety of heat cover forms can be customized. Ø Aluminum potting uniform temperature heating tube, quick plug-in heating tube power connector. Ø The anti-scald safety design can effectively ensure the convenience and safety of users. Applications It is suitable for the heat sealing test of various plastic film, plastic composite film, paper-plastic composite film, co-extrusion film, aluminized film, aluminum foil, aluminum foil composite film and other film-like materials. The heat cover is smooth and flat, and the heat seal width can be adjusted according to the user It can also be designed to meet the needs of various types of plastic hose sealing experiments. Technical Standard Using the hot-press sealing method, the sample to be sealed is placed between the upper and lower heat-sealing heads, and the sample is sealed under the preset temperature, pressure, and time. The instrument meets a variety of national and international standards: QB/T 2358, ASTM F2029, YBB 00122003.
