LH-25A(B) High Frequency Induction Heating Machine

LIHUA induction heater adopts the Infineon MOSFET, latest IGBT power units and frequency conversion control techniques with high efficiency, low energy consumption and higher output power.

With constant current and constant power control function, greatly optimize the heating process of metals, realize efficient and fast heating, and fully exert the superiority of the products.

IGBT high frequency induction heating machine is doubled electric saving than traditional electron tube high frequency heating machine in same using condition, reduce eletrical load and save cost.

With 100% loading rate design, IGBT indcution heater can work in 24 hours without stop.

With heating-retaining-cooling three stages function setting, it is benefit for improving the heating quality and simplifying manual operation.

With multiple status display of overflow, overvoltage, low water,phase failure and load malfunction, providing higher reliability and sustainability.

Regarding to select power supply, it is based on the power and frequency. The higher the frequency, the shallower the heating depth, and the lower the frequency, the deeper the heating depth.

The induction heating machine can be equipped with infrared detector to automatically control temperature, improve the quality of heating and facilitate manual operation.

Can be equipped with chiller to be an integrated equipment, circulating water cooling, saving water, closed space provent machine from dust.

Induction welding(Brazing, silver welding, copper welding)

  • It is mainly heating the solder to a certain temperature to make the solder melting, so as to welding different materials of metal together, the specific application is as follows:
  • Various hardware tools: Solid center bit, Planer tool, Reamer, Hobbing, Carbide turning tool, TCT Circular Saw Blade, Drilling tool, Grinding tools, Diamond tool and so on.
  • Various machinery parts: Silver welding , copper welding of Hardware bathroom products, refrigeration copper accessories, lighting accessories, precision mould parts, hardware handle, eggbeater, steel and alloy steel, steel and copper, copper and copper and other different metals. 
  • Compound pot bottom brazing: It is mainly used for three layers brazing of stainless steel pot bottom and aluminum plate with round shape, square shape and other special shape. It can also be used for other metal plane brazing.
  • Heating tube brazing: It is mainly used for brazing between stainless steel flat bottom, aluminum sheet and various shapes of electric heating pipe.
  

Induction Heating(Hot forging, hot fitting, hot melting):

  • Hot forging is mainly to heat the workpiece to a certain temperature (according to the different heating temperature of the material), and the workpiece is formed into other shapes by punching, forging or other forms. Such as Drill rod, Rivet,Bronze lock, Machine parts, Fastener, Standard parts, Art craft, Kitchen tableware, Handle, Watch blank, Watch case and so on.
  • Hot fitting mainly refers to heat metals between different kinds of metals or between metals and non-metals to connect by the principle of thermal expansion or thermal fusion. For example, the copper core of the computer radiator and aluminum sheet, welding of speaker mesh, the composite of Rigid plastic pipe, the sealing of the aluminum foil (toothpaste), the motor rotor, the sealing of heat tube and so on.
  • The melting mainly refers to melt metal to liquid at high temperature, applicable to Iron, Steel, Copper, Aluminum, Zinc and other noble metals (such as Gold, silver).

Induction heat treatment  (Surface quenching, annealing, tempering)
  • It is mainly change the hardness of the metal material through the heating of the workpiece, the applications are as below:
  • All kinds of hardware tool and hand tools: Such as Pliers, Wrench, Hammer, Axe, Screwdrivers, Scissors (garden shears) and so on.
  • All kinds of automobile and motorcycle fittings: Such as crankshaft, connecting rod, piston pin, sprocket, aluminum wheel, valve, rocker shaft, drive shaft, small shaft, fork and fittings;
  • Various electric tools: Such as gear, axis.
  • Machine tool industry: Such as the surface of machine tool, machine tool guide rail, etc.
  • Various hardware metal parts, machining parts: Such as shaft, gear (sprocket), CAM, chuck, clamping, etc.
  • Hardware mould industry: Such as small mold, mold accessories, mold inner hole, etc.
  • Annealing of various stainless steel industrie: Such as annealing and stretching of stainless steel pots and cans, annealing of tanks, stainless steel pipes, stainless steel tableware, stainless steel cups, etc. ;
  • Annealing of other kinds metal workpieces such as golf clubs, copper locks, hardware accessories, kitchen knife, copper pot, aluminum pot, aluminum blade barrel, aluminum radiator and various types of aluminum products.
