  • Steel Rule Die-Cutting 2019-05-09 Steel Rule Die-Cutting
    What is Steel Rule Die-Cutting? Why should we prefer steel die-cutting to conventional technology.
  • The Factors Affecting RF Welding Effect 2017-08-22 The Factors Affecting RF Welding Effect
    The factors that affecting the rf welding effect and product quality in consequence.
  • Generator Power/Sealing Area Chart 2017-08-22 Generator Power/Sealing Area Chart
    Generator power of a RF welder for welding are of vinyl sheet
  • What is thermoplastic? 2017-08-22 What is thermoplastic?
    A thermoplastic, or thermosoftening plastic, is a plastic material, a polymer, that becomes pliable or moldable above a specific temperature and solidifies upon cooling.
  • Efficient RF sealing techniques 2017-08-09 Efficient RF sealing techniques
    Sealing can be made more efficient by controlling heat loss. The heat is generated in the plastic; therefore, the tooling actually sucks heat out of the material since the tooling temperature is below the melt temperature of the plastic (240°–320°F).
  • comparing rf with other sealing technology 2017-08-09 comparing rf with other sealing technology
    Few products are as well suited for a particular manufacturing process as are medical bags for RF sealing. No other bag-sealing method yields the consistency, capacity, and quality afforded by RF technology.
  • Sizing rf sealers and Tooling 2017-08-09 Sizing rf sealers and Tooling
    Sizing and tooling of the RF welder
  • how RF works? 2017-08-09 how RF works?
    The power supply converts power from an ac line source into high-voltage direct current. An oscillator tube/resonator combination then converts the direct current into 1000 to 1500 V of alternating current operating at a frequency of 27.12 MHz ±0.6%.
  •  what is rf sealing? 2017-07-27 what is rf sealing?
    RF sealing is the use of radio waves—typically at 27.12 MHz—directed through two or more layers of a dielectric plastic in conjunction with pressure so that molecules of all layers of the plastic combine when the material becomes molten.
  • Sealability of Plastic Materials through RF Heating 2017-07-27 Sealability of Plastic Materials through RF Heating
    RF sealing technique works well with PVC and some other plastic materials. But not all plastics can be heated with radio frequency. Polystyrene, polypropylene, and polyethylene are common materials that do not respond to RF energy.
