What Is High Frequency Welding Machine?
2012/7/8 1:15:02

Overview of High Frequency Welding Machine
High Frequency Welding Machine for the high frequency dielectric heating and cut off the device. Due to dielectric loss and fever, the pressure to achieve the purpose of welding or forming. Dielectric material proportional to the heat and the square of the electric field strength, frequency, and dielectric constant. Equipment for the two-stage pressure action, using the gas pressure can just weld the action only when cutting action when the need to open the oil pressure. High Frequency Welding Machine is widely used in blister cardboard packaging, PVC, PETG, GAG, EVA, PEVA, TPU, PU synthetic leather materials can be completed welding and cutting operations at the same time! Both at the same time processing, a complete welding and cutting operations.
High-frequency fusing machine models generally: rotary and sliding table.

A high frequency fusing machine theory
High Frequency Welding Machine is a high-frequency devices, the tube self-excited oscillator to produce high-frequency electromagnetic fields. Pressure in the high-frequency electromagnetic fields on the processing object, the motor between the dielectric material in the role of high frequency electric field of molecular polarization, arranged according to the direction of electric field due to the high-frequency electric field to change direction at great speed. internal molecular dielectric material is the intensification of high-speed movement friction between self-generated heat in the mold under pressure to achieve the purpose of welding or embossing of the main models are: the high-frequency synchronous fusing machine, single head to push the disc high frequency machine, single rotary head high frequency machine, and so on.
Second, the high frequency fusing machine structure
A native two push plate, two work stations, if the turntable, this machine has three work stations. The operator simply into products, to promote the push plate to trigger a micro switch, mold will automatically drop, heating up the whole process simple and safe, the staff without special training, you can use this machine. Native two slide, the operator simply into the product, press the forward button decline in Taiwan, the nose will automatically drop, heating, rise, slide exit, complete all the simple operation, the staff without special training made interference without the use of the machine; adjust the output power of: LK-specific low-loss coaxial oscillator, you can at any time due to the mold size and the thickness of rubber and tone than the output power of the strength of the operating frequency machine telecommunications, not the other brands can compare, contribute to the tone than can also tie in with the time, the maximum output in the shortest time fuse products, increase production; Protection: limiting: when the output power adjustments is too large, cut high-cycle output it can be protected inside the tube will not be damaged due to excessive current; high-frequency synchronous fusing machine is a high-frequency devices, the entire swing frequency for 13.56MHz, 27.12 MHz, 40.78 MHz, in line with international standards of industrial band, high frequency tube since induced oscillator frequency electromagnetic fields, the processing of plastic in the high frequency electric field between the upper and lower electrodes, the internal molecules from the force of movement friction welding purposes, in the mold under pressure welding results. 4th generation in line with European environmental standards, mainly for the molding of various plastic products, auto-trimming and different shape of the blister or blister. PVC double-sided blister sealing, sealing of plastic and paper card, environmental protection, APET film equivalent, soft line indentation punching forming, trimming environmental the APET sided plastic seal contract, the closure of special materials. Blister packaging (including the upper and lower double blister heat sealing trimming, cutting edge of the blister with cardboard heat), automotive interior parts, trademarks, stationery box, raincoat, inflatable toys, plastic cover, cool liquid mat, footwear, cushions kinds of bags, soft hand bags and other heat processing, the patterns of a variety of concave and convex shapes, letter characters.
Third, the parameters and characteristics
Parameter index
(1) Power: 8KW/12KW/15KW/20KW/25KW on the plate: 400X350mm or the 500X400mm under plate: 650X530mm or 730X680mm 4. Upper and lower electrode spacing: 140mm
Mechanical characteristics
Machine characteristics: PVC, PU, TPU hot press, mark, eager synchronization is complete, the Duty Cycle stable high frequency machines in strict accordance with the provisions of the International Radio Interference Committee (CISPR) the industrial band 27.12/40.68MHZ, and the design of frequency stabilizer and the frequency magnetic leakage suppressor, minimum interference and external devices. Contribute to an exceptionally strong high frequency machine with low-loss coaxial resonator, the output waveform, high quality factor, contribute to an exceptionally strong rapid welding. Oscillating current to stop the same modem to set the output power of high frequency machines, the adjustment is simple and convenient to set the desired oscillation current, according to the size, thickness, and degree of control of welding, to ensure the welding quality of the product homogeneity. Spark suppression frequency machine has a high sensitivity spark suppression circuit, the unbalance current can be accurately detected sparks, spark quickly cut off the oscillator circuit to produce sparks instant suppression, molds, raw materials and products to minimize damage. Security cycle machine is equipped with overvoltage and overcurrent protection devices in work the exception can be automatically cut off the high pressure in order to protect oscillation tubes and rectifier, at the same time avoid improper operation frequency drift.
, High Frequency Welding Machine features
1) output power adjusted using a unique low-loss coaxial oscillator, you can always tune than the strength of the output power due to the mold size and the thickness of the rubber. Operation PVC rain pants heat sealing machine (not made to interfere with telecommunications, and effortless can also be adjusted with the time, the maximum output, welding products in the shortest possible time and increase production. 2) protection device a current-limiting protection: will cut off the high cycle output when the output power adjustments is too large, it can be protected inside the tube will not be damaged due to excessive current. spark protection: in the course of their work, if the mold to produce arcing phenomena, the protector will cut off the output, the mold also rise, leaving product, so that the mold will not flash and damage. tight sudden system: in the course of their work, you can always stop the high-frequency output at the same time mold back into place. 4) Redu thermostat addition to high-frequency self-heating, motor 2000W heating element and thermostat allows mold preheat to speed up the welding time and the elimination of arcing phenomena. 5) increased the distance with a three solenoid valves, with time, can freely adjust the cylinder rise in the distance, in order to reduce the cylinder launch and recovery time required to improve production speed. 6) strong Output System A. output power is strong, the local oscillator Duty Cycle 27.12MHZ or 40.68MHZ, in line with international standards of industrial band, a variety of control devices special electronic circuits, to avoid improper operation and the fastest time of welding products, improve product yield; B. high sensitivity spark protection device, when the spark is generated can be automatically cut off the high-cycle loop, so that damage to parts and objects reduce automatically cut off when the current is too high, the high pressure to ensure oscillation tubes and rectifier ;
