High frequency welding

Relatively coarse-grained oxidized gas blacks with high volatiles contents are especially suitable for plastics with good electrical insulation (e.g., cable sheathing compounds, plastics for high-frequency welding, toners). [Pg.175]

ISO 472 defines high-frequency welding , dielectric welding and RF welding ... [Pg.72]

High-frequency welding probably is the technique used most widely for joining both rigid and flexible poly(vinyl chloride) film and sheet. (It has been called also radio-frequency or capacitance heating welding.)... [Pg.76]

TABLE VI Typical pressures required for high-frequency welding. The figures given are per square inch or per square metre of the face of the welding tool... [Pg.85]

High-frequency welding is very suited to the manufacture of a wide range of products in the fields of medicine and surgery—as containers for solutions,... [Pg.87]

High-frequency welding has a part to play in this field, including the following. [Pg.88]

Since the friction of dipoles in an alternating field produces heat, polar polymers can be heated by the application of radio-frequency field in fabrication processes (see high-frequency welding. Chapter 2). [Pg.354]

High-frequency welding n. A method of welding thermoplastic articles in which the surfaces to be joined are heated by contact with electrodes of a high-frequency electrical generator. [Pg.495]
