Product Description:

Feature: 1. IGBT inversion technology reduce operating cost 2. High efficiency up to 90% 3. LC series circuit and voltage feedback design achieve energy saving up to   30% compared with SCR technology induction machine 5. Diode rectification technology make sure high power factor –never less 0.95 6. Soft switch technology and prefect protection system enhance good reliability

7. Suitable for heating medium size of part.

1.All-solid-state IGBT frequency conversion and power adjustment, soft-switching responance dual-control and frequency automatic tracking technology is the reliability of guarantee.  module and soft switching inverting technologies are used in the production of the generator, higher reliability can be achieved;

2.Small size and portable , compared with SCR controlled machine, only 1/10 working space is needed, greatly reduce occupation space;

3.High efficiency and energy saving: a high power factor and power efficiency within the scope of full power.

4.With wide frequency range from 1-20KHZ automatic trackin ability, no need adjustment at scene.

5.100% duty cycle , 24hours continuous working ability at maximum power.

6.Constant output voltage or power control modes are alternative;

7.Full display of output power, output frequency, output voltage and current.

8.The timer function: heating time and retaining time: 0.1~99.9second.

Application: a. Pre-heating for forging and forming

1 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.

2. 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.

3. Smelting mainly aims to melt the metal into liquid by using the high temperature, which is mainly applicable to the smelting of iron, steel, copper, aluminum, z

b. Brazing

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) 

 

c. Heat treatment such as surface hardening

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:  

d. Melting for aluminum, copper and small capacity metal melting ecte. Pipe Pre-heating

f. Pipe heating for elbow machine
