Working principle of high frequency plastic welding machine High frequency medium heating technology is applied in the field of plastic packaging. One kind of equipment is to generate a high-frequency electric field by using an electronic self-excited oscillator. This high-frequency electric field is applied to the electrode. Under the effect of the high-frequency electric field, the plastic's molecular structure produces polarization and generates heat itself. Under the effect of pressure, it can achieve hot melting, Next, we will introduce the advantages and applications of the high frequency plastic welding machine! Welcome to read!
(1) Advantages of the machine: High frequency plastic welding machine generally uses plastic to plastic welding, plastic to paper card, or welding with paper card to paper card; Generally, the surface of the welded paper card is coated with PVC or APET, PETG glue when printing, and under the action of high frequency, the molecular flow permeates the welding as a whole. The high cycle plastic welding machine is the preferred equipment for plastic heat sealing. Its welding temperature gauge is uniform, the surface is smooth and clean, and the appearance is beautiful. It solves the problems such as deformation and blistering caused by simple hot pressing. The anti electromagnetic radiation interference shielding system adopted by Shenghao Machinery's high cycle electromagnetic wave greatly reduces the intensity of direct radiation of high cycle electromagnetic wave to human body.
High cycle heating device can be installed according to the characteristics of plastic products for heat sealing welding, which can be used to heat both upper and lower molds. The corresponding temperature can be adjusted at will according to the nature of materials, mainly for mold surface heating. The over-current protection system of Shenghao Machinery is mainly used to protect the unnecessary electronic tubes from burning due to excessive current. The latest American anti ignition device system mainly uses NL5557 highly sensitive spark device, which can instantaneously protect the high-frequency mold from burning due to excessive current.
(2) Main scope of application.
High frequency is mainly applicable to pure PVC, TPU, EVA or plastic and sheet materials with more than 10% of any PVC content, cardboard coating, soft and hard plastics, plastics, artificial leather, clothing fabrics, etc., heat sealing, welding, packaging.
(3) Main applicable industries:
