　　High frequency fusing machine characteristics

　　A) adjust the output power

　　Using special low-loss coaxial oscillator, you can always due to the size and thickness of the rubber mold and adjusting the output force strength. The operator PVC rain pants heat sealing machine (does not make interference telecommunications, efforts to adjust with the time for maximum output, in the shortest time welding products, increase production.

　　2) protection device

　　a. limit protection: When adjusting the output power is too large, it will cut off the high cycle output tube to protect the machine will not be damaged due to excessive current.

　　b. spark protection: in the work process, if the mold produces the phenomenon of flashover, the protector will cut output, mold will automatically rise, leaving the product, so that mold will not flash and damage.

　　c. Tight sudden system: In the course of their work, you can always stop the high-frequency output simultaneously mold back in place.

　　4) Heat Thermostat

　　In addition to its high-frequency heating, the motor and 2000W heating element and die preheating temperature welding time and speed to eliminate the phenomenon of flashover.

　　5) increased from

　　There is a three valve can be used with time, can freely adjust the distance of the cylinder up, launch and recovery of the cylinder to reduce the time required to increase production speed.

　　6) Powerful output system

　　A. electrical power output of the local oscillator generated Duty Cycle 27.12MHZ 40.68MHZ, in line with international standards for industrial band, various control devices special electronic circuit, to avoid improper operation, can the fastest time of welding products, improve product Yield;

　　B. sensitive spark protection device, when a spark occurs, it can automatically cut off the high-cycle loop, so that reduces damage parts and objects, when the current is too high, automatically cut off the pressure to ensure oscillation tubes and rectifier;

　　High frequency fusing machine mold

　　High frequency fusing machine mold: production of objects for defining the shape and size of the device.Industrial production for injection molding, blow molding, extrusion, casting or forging molding, smelting, stamping, drawing and other methods to obtain the desired product of the various molds and tools.

　　Classification of mold

　　According to the molding material, the mold can be divided into metal molds and metallic molds. Metal mold is divided into: casting mold (non-ferrous casting, steel casting), and forging molds, etc.; non-metallic mold is also divided into: plastic molds and inorganic non-metallic mold. The mold itself according to the different materials, the mold can be divided into: sand mold, metal mold, vacuum mold, wax mold, and so. Which, along with the rapid development of polymer plastic, plastic mold and is closely related to people's lives. Plastic Mold can generally be divided into: injection mold, extrusion mold, gas assist mold and so on.

　　Mold Maintenance Considerations

　　1, the mold after prolonged use must grind edge, grinded edge surfaces must be demagnetized, not with a magnetic, or prone to blocking material.

　　2, springs and elastic components in the course of the spring most vulnerable, usually a fracture and deformation phenomena. The approach taken is to be replaced, the replacement process must pay attention to the spring specifications and models, specifications and models spring by color, diameter and length of three to confirm that only three are the same circumstances that can be replaced.

　　3, the process of using punch mold prone to break, bend, and eating a bad phenomenon, punch sets are generally eating bad. Punch and damage generally sets with the same specifications of the parts to be replaced.The main parameters of the punch working part size, the mounting portion size, length size.

　　4, fastening parts, check for loose fasteners, damage phenomena, the approach is to find the same specifications for replacement parts.

　　5, binder components such as pressure plate, Urethane, etc., unloading parts such as stripper plate, pneumatic roof materials. Care to check all parts of the relationship and accessories for damage, repair the damaged part, pneumatic ejector check for leaks, and the specific situation to take action. Replace damaged such as the trachea.

　　High frequency fusing machine interference prevention measures

　　1 plant under construction when doing system shielding, with 0.3 galvanized sheet or small-purpose wire shielding around the 50mm iron pipe into the ground 2-3 meters every two meters hit a mesh of the shield and iron pipe connection, so high-frequency signal is not easy to radiate out from the factory, played overall shielding effect.

　　(2) high-frequency machine frame and the shell is well grounded, strengthening the body shielding, radiation is recommended to reduce body width 50mm × 50mm or more, the length is not less than 2m of angle iron into the ground as grounding, and then over copper wire 10mm2 High frequency machine frame and the shell is connected with the grounding. Connection should be as short as possible, do not circle, try to avoid turning, so you can enhance high-frequency portion of the shield machine body, reducing the intensity of the interference signal radiating outward. If the car (room) room at more than one frequency machine, high frequency machine best each (or two adjacent) are buried in the machine next to a nearby ground.

　　3 Adjust the position and direction of the high-frequency machine: If the housing wall hanging cables, high frequency machine is best to set away from the end of the cable. In addition, ordinary type high frequency machine tube at right angles to the chassis successful
