LHG-03A(C) Ultrahigh Frequency Induction Heating Machine

  • LHG-03A(C) Ultrahigh Frequency Induction Heating Machine
  • LHG-03A(C) Ultrahigh Frequency Induction Heating Machine
The working principle of ultrahigh frequency induction heating equipment is that place the workpiece in the inductor, the inductor is usually a hollow copper tube with intermediate or high frequency alternating current (1000-300000Hz or higher). The alternating magnetic field produce induced current with the same frequency in the workpiece, the induced current is not uniform, it is strong on the surface but weak in the internal core, the use of the skin effect, can make the rapid heating of the workpiece surface, in a few seconds, the surface temperature rises to 800-1000 ℃ and the core temperature is very small. Based on the skin effect, the surface of workpiece can be heated rapidly, can be heated to 800-1000ºC in seconds, but the increasing of internal temperature, is small.

Lihua ultrahigh induction heating equipment have the features as below:

Ultrahigh frequency(minimum welding 0.1mm), small bulk, light weight, low failure rate, saving energy (Saving energy 70% than glass ceramics electron tube high-frequency machine).

Welding point is firm, beautiful and exquisite, the shape of weldment are not limited, surface pattern won’t be damaged, metal internal crystal structure is unchanged, annealing range is small and no obvious welding scar.

Widely used in connector welding of metal glasses manufacturing industry, electrical and electronic industry, non-touch welding of small relay, high voltage-resistant welding in refrigeration industry, parts welding of jewelry industry and welding of metal ornaments and metal manufacturing industry.
  • Electric industry: the soldering of fine wire electronic components.
