高周波

高周波是一种频率远高于常规电磁波的高频振动能量波，其频率通常大于100KHz，属于电磁波的一种。高周波技术主要利用高频电磁场使物料内部分子间互相激烈碰撞产生高温，从而达到焊接、熔接、切割或改性的目的。

高周波设备通常由高频振荡器和加热机构两个主要部分组成。高频振荡器产生高频电磁场，将其施加在电极上，被加工物件置于电极之间。在高频电磁场的作用下，物件内部分子被激化而高速运动，相互摩擦产生热量并熔化。在模具的压力下，达到熔接、压花或切断的目的。

高周波技术具有多种优点，如输出电力强大、熔接速度快、质量稳定等。它广泛应用于塑料焊接、金属表面处理、电子元件微细加工等领域。在塑料加工行业，高周波塑胶熔接机是塑料热合的首选设备，广泛应用于PVC、TPU、EVA等塑料材料的焊接、封口和压花。此外，高周波技术还用于纺织品的热合、压花和切割，以及汽车内饰件的焊接和组装等。

High Frequency (or High Frequency Wave) is a type of electromagnetic wave with a frequency much higher than conventional electromagnetic waves, typically exceeding 100KHz. High-frequency technology primarily utilizes high-frequency electromagnetic fields to cause intense collisions between molecules within materials, generating high temperatures and achieving welding, fusing, cutting, or modification.

High-frequency equipment typically consists of two main components: a high-frequency oscillator and a heating mechanism. The high-frequency oscillator generates a high-frequency electromagnetic field and applies it to the electrodes. The workpiece is placed between the electrodes. Under the action of the high-frequency electromagnetic field, the molecules within the workpiece are activated and move rapidly, generating heat through friction and melting. With the pressure of the mold, welding, embossing, or cutting is achieved.

High-frequency technology offers various advantages, such as powerful output, fast welding speeds, and stable quality. It is widely used in plastic welding, metal surface treatment, and micro-processing of electronic components. In the plastic processing industry, high-frequency plastic welding machines are the preferred equipment for plastic heat sealing, widely used in the welding, sealing, and embossing of PVC, TPU, EVA, and other plastic materials. Additionally, high-frequency technology is used for heat sealing, embossing, and cutting of textiles, as well as for welding and assembly of automotive interior parts.
