Application:

Brazing: it can be used for the brazing of various hardware cutting tools,  diamond tools including diamond circular saw from diameter 300-2500mm, abrasive tool, drilling tool, alloy saw blade, hard alloy cutter, milling cutter, reamer, planning tool and solid center bit etc.

HF-25A/AB model suitable to used for the brazing of circular saw and other tools, usually 4 to 9 seconds is needed to braze one diamond blade.

Brazing of various hardware mechanical gadget: silver brazing and copper 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.

Induction Brazing of Heating disc of Electric hot-water kettle, electric coffee kettle, cookware (induction brazing of stainless steel flat base, aluminum sheet and tubular electric heating elements of various form) 

Quenching: quenching for various hardware and tools, such as plier, wrench, hammer, ax, screwing tools and shear(orchard shear).

Quench for various automobile and motorcycle fittings, such as crankshaft , connecting rod, piston pin, chain wheel, aluminum wheel, valve, rock arm shaft, drive shaft, small shaft and fork.

Various electric tools: gears and axes.

Quench for machine tool: lathe deck and guide rail.

Quench for various hardware metal parts and machined parts, such as shaft, gear(chain wheel), cam, chuck and clamp etc.

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

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.

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 alumimum products.

Forging : small rod forging

Melting: small capacity metal melting. For example:

Hot fitting: embedded welding of copper core of computer radiator with aluminum sheet and speaker web, compound of steel and plastic tube, sealing of aluminum foil (tooth paste ) motor rotor and sealing of tubular electric heating element.
