PVC Bag Sealing Automatic High Frequency Welding Machine

PVC Bag Sealing Automatic High Frequency Welding Machine belongs to the high frequency equipment in PVC bag automatic making by film rolls, this machine by electronic oscillation tube produces high frequency electromagnet fields, processing PVC Film between the upper and lower electrode of HF/RF electromagnetic field in automatic motorized roll material feeding system to exert the process of cutting, welding, and edge trimming, the internal friction molecules by polarization and mutual movement itself to generate heat, under the pressure of the mold to achieve the purpose of welding,because of bonding achieved by heated material itself, and only in the localized pressure, the PVC bag is very nice in its tear-resistance and appearance, material that can be used with HF/RF sealing include polyurethane, PVC and Polymers like PET, EVA and some ABS

01: Application

PVC Bag Sealing Automatic High Frequency Welding Machine adopts high frequency dielectric welding technology in PVC bag making from two layers to five layers of laminated seam bonding, the edge trimming also can achieved during shaped welding, high frequency energy delivered to the thermoplastic films placed between upper and lower electrode, two thru five layers plastic films can be constituted by this HF welding machine, the shape of upper electrode (mold) is made according to the desire embossing or welding shape on the plastic, and the lower electrode could be the shape of product appearance or just a piece of metal plate, the top electrode is connected to the hydraulic cylinder in order to apply pressure when welding and edge cutting, high frequency provide a local heat only in the melting line through the excitation of polymer molecular flip in friction, resulting in melting in localized shaped line and mixture the pressed laminated material element together, then top electrode apply pressure above the material stopped on the bottom electrode. Bringing a complete fusion, then stop applying the high frequency current, the brief cooling enhance the material solidification, material are welded at the point of contact with die, the strength of materials is stronger that the original that after high frequency welding, and the melting heat is generated from material inside, which is quick cooling down without causing any deformation around the material itself, So, the high frequency welding of automatic roll feeding conjunction in PVC bag making is always first-considered

PVC Bag Sealing Automatic High Frequency Welding Machine configues units of auto tranfering system, flattening deivce, punching Sect,High Frequency sealing,welding and collecting system for automatic production in PVC bag making
 

PVC Bag Sealing Automatic High Frequency Welding Machine is the principle of high frequency oscillation tube emits high frequency electromagnetic waves in the oscillation barrel,which are transmitted to the upper and lower electrode to exert material itself localized heat by polymer inside friction of polarization molecular, so that the PVC plastic material can generate heat energy, when the heat energy reaches the melting point of PVC material. The welding and fusing pressing is carried out, the welding temperature is uniform inside and outside, and the heating speed and temperature are controllable, this HF/RF welding machine is conjunct with rolling material auto feeding system for auto production in PVC bag making
 

PVC Bag Sealing Automatic High Frequency Welding Machine can be modified to exert the process of welding, cutting, edge trimming in making, PVC Bag, urine bag, blood bag and other various shaped lamination seam sealing bag, if you cannot find your concerned elements or you have exceptional demands in your production, please let us know its details for tech verification prior to offer, the experienced staff members in keepleader are always ready to work with you in sharing their solution and ideas for your comparison
