LIHUA IGBT induction heaters adopt the latest MOSFET, 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 to greatly optimize the heating process of metals, realize efficient and fast heating, and fully exert the superiority of the products. Power consumption is half of traditional electron tube high frequency induction heating equipments under the same conditions. With 100% load design, can work for continuous 24-hour a day. Infrared temperature detector can be equipped to realize the automatic control of temperature, improve heating quality and simplify manual operation. With heating-insulating-cooling three stages function setting, the heating and insulating time required can be get to accommodate to the batch and repeated heating situations. With multiple status display of overflow, over voltage, low water, phase failure and load malfunction, providing higher reliability and sustainability. Select power supply according to the power and frequency. The higher the frequency, the shallower the heating depth, and the lower the frequency, the better the diathermancy.

Application of Induction heating equipment:

• Hot forging aims to fabricate the work pieces of certain temperature (different materials require different temperatures) into other shapes through forging press with the help of punch press, forging machine or other equipments for instances, hot extrusion of watch case, watch flan, handle, mold accessory, kitchen and table ware, art ware, standard part, fastener, fabricated mechanical part, bronze lock, rivet, steel pin and pin.
• Hot fitting refers to the connection of different metals or metals with nonmetals through the heating based on the principle of hot expansion or hot smelting, for instances, 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 peel) motor rotor and sealing of tubular electric heating element.
• melting mainly aims to melt the metal into liquid by using the high temperature, which is applicable to the smelting of iron, steel, copper, aluminum, zinc as well as various noble metals.

Heat treatment (surface quenching):

• Quench for various hardware and tools, such as pliers, wrench, hammer, ax, screwing tools and shear (orchard shear).
• Quench for various automobile and motorcycle fittings, such as crankshaft, connection rod, pinton pin, chain wheel, aluminum wheel, valve, rock arm shaft, small shaft and fork. Various electric tools, such as axes and gear.
• Quench for machine tools, such as lache 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

Welding (brazes welding, silver soldering and brazing):

• 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.
• Welding of various hardware mechanical gadgets, silver soldering and brazing of metals of the same 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.
• Compound pot bottom welding is mainly applicable to the braze welding circular, square as well as other irregular plain pot bottom. It is also applicable to plain braze welding of other metals.
• Welding of heating disc of electric hot-water kettle mainly refers to the braze welding stainless steel flat base, aluminum sheet and tubular electric heating elements of various forms.

Annealing (tempering and modulation):

• 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 aluminum products.
