A. Heating (hot forging, hot fitting and smelting):
1 The aim of hot forging is to forge workpieces of a certain temperature (different materials require

    different temperatures) into other shapes with the help of a press, forging machine or other equipment,

    as for example, hot extruded watch cases, watch flanges, handles, mold fittings, kitchenware and cutlery,

    works of art, standard parts, fasteners, manufactured mechanical parts, brass locks, rivets, steel pins

    and pins.
 

2. Thermal bonding is the connection of different metals or metals with non-metals by heating according to

    the principle of thermal expansion or thermal fusion, e.g. the embedded welding of the copper core of

    computer radiators with aluminium plates and speaker grids, the compounding of steel with plastic tubes,

    the sealing of  aluminium foil (toothpaste skin), the sealing of motor rotors and tubular heating elements.
 

3. Smelting is basically the use of high temperature to dissolve metals into liquid, mainly applies to the

     smelting of iron, steel, copper, aluminum, zinc and other various precious metals.

B. Heat Treatment (surface quench):
It is mainly aims to change the rigidity of the metal materials through the heat treatment to work pieces. Detail

applications are stated as follows:
 

1. Quench for various hardware and tools, such as plier, wrench, hammer, ax, screwing tools and shear

    (orchard shear).
2.Quench for various automobile and motorcycle fittings, such as crankshaft, connecting rod, piston pin, chain

    wheel, aluminum wheel, valve, rock arm shaft, semi drive shaft, small shaft and fork.
3. Various electric tools, such as gear and axes.
4. Quench for machine tools, such as lathe deck and guide rail.
5. Quench for various hardware metal parts and machined parts, such as shaft, gear (chain wheel), cam, chuck

     and clamp etc.
6. Quench for hardware molds, such as small-size mold, mold accessory and inner hole of mold.

C. Welding (braze welding, silver soldering and brazing)
It mainly aims to melt the solder by heating it to a certain temperature for the purpose of connecting two types of

metals of the same material or different materials.
 

1. Welding of various hardware cutting tools, such as diamond tool, abrasive tool, drilling tool, alloy saw blade,

    hard alloy cutter, milling cutter, reamer, planning tool and solid center bit.
2. Welding of various hardware mechanical gadget: Silver soldering and brazing of metals of the same variety or

     different varieties, such as hardware toilet and kitchen products, refrigerating copper fitting, lamp decoration

     fitting, precision mold fitting, hardware handle, eggbeater, alloy steel and steel, steel and copper as well as

     copper and copper.
3. Compound pot bottom welding is mainly applicable to the braze welding of circular, square as well as other

     irregular plain pot bottom. It is also applicable to plain braze welding of other metals.
4. Welding of heating disc of electric hot-water kettle mainly refers to the braze welding of stainless steel flat

     base, aluminum sheet and tubular electric heating elements of various forms.

D. Annealing (tempering and modulation):
1. Annealing of various stainless steel products, such as stainless steel basin, annealed and extruded can, annealed

    folded edge,annealed sink, stainless steel tube, tableware and cup.
2. Annealing of various other metal work pieces, such as golf ball head, cue, brass lock, hardware copper fitting, kitchen

    knife handle, blade, aluminum pan, aluminum pail, aluminum radiator and various aluminum products. 1. Heating

    (hot forging, hot fitting and  smelting):

Operating Principle

Frequency conversion electromagnetic induction heating or induction heating for short is a method for heating metal

materials by converting power frequency power supply into that of specific range based on the principle of electromagnetic

induction. It is mainly applicable to the metal hot working, heat treatment, welding and melting. This type of heating

technique is also applicable to packing industry (such as sealing of aluminum foil used in medicine and food industry),

semiconductor material (such as extruded monocrystalline silicon and heated affixing metal parts for auto glass). Basic

components of induction heating system include induction coil, AC power source and work pieces. Induction coil can be

fabricated into different shapes as per different heated objects. The coil is connected with the power source providing

alternating current for coil. The alternating current possessed by the coil can create a alternating magnetic field passing

through the work pieces to produce eddy flow as required by heating.

Advantages of Induction Heating Equipment

1. Fast heating: the minimum rate of heating is less than 1 second (rate of heating is available for adjustment and control).

2. Wide coverage of heating: it can be used to heat various metal parts (replace removable induction coil as per different

                                                  perating switches).

3. Easy installation: it can be used once it is connected with power source, induction coil as well as water supply pipe and

                                  rising pipe; it is small in size and light in weight.

4. Easy operation: you can learn to operate it within several minutes.

5. Fast start-up: it can be started to perform heating operation on condition that water and power supply is available.

6. Low power consumption: As compared with conventional vacuum tube high frequency equipments, it can save the power

                                                 by approximately 70%. The smaller the size of the work piece is, the lower power consumption

                                                 would be.

7. High effectiveness: it has such features as uniform heating (it is applicable to adjust the spacing of the induction coil to

                                      ensure the appropriate temperature as required by each part of work piece), fast warming and limited

                                      oxic horizon, and can guard against any waste after annealing.

8. Comprehensive protection: it has such functions as overpressure, over-current, overheat and water shortage alarm indications

                                                    as well as automatic control and protection.

9. Controllable temperature: it is applicable to control the temperature for heating work pieces as per the preset heating time,

                                                and thereby control the heating temperature at a certain technical point.

10. Comprehensive full load design: it can work continuously for 24 hours.

11. Small size and light weight: it has a weight of only several dozens of kilograms, of which, the limited floor space can effectively

                                                     save the workshop space.

12. Elimination of high voltage: it requires no step-up transformer which may produce approximately ten thousand voltage, and

                                                      thus can ensure the maximum safety.
