How Induction Heating Device Works

This 2.5KW-3.5KW Induction heater is a small and medium power device, suitable for local heating, small workpiece processing, laboratory and civilian scenes. The core advantages of induction heater 2.5kw are fast heating, precise temperature control, strong portability, suitable for applications with high requirements for thermal efficiency, energy consumption and flexibility.

2.5KW 3.5KW induction heater  use for industrial fields

1. Metal processing and heat treatment

Small mold preheating: preheat the mold surface to 150-300℃, shorten the injection molding and die casting cycle, and reduce thermal shock.

Case: Preheat the mold before injection molding of plastic parts, single preheating time <5 minutes.

Precision parts annealing: eliminate machining stress, suitable for local annealing of tools and shaft parts (hardness HRC30-50).

Advantages: temperature fluctuation <±5℃, avoid workpiece deformation.

2. Welding and brazing

Welding of small metal parts: welding of copper tubes and stainless steel joints with a diameter of less than 10mm, and the weld strength is greater than 80% of the parent material.

Application of induction heater 2.5kw: welding of copper tubes of refrigeration equipment and connection of pins of electronic components.

Laboratory brazing: induction heater 2.5kw is used for small-batch brazing experiments in scientific research institutions, such as vacuum brazing of ceramics and metals.

3. Melting and casting

Smelting of precious metals: melting of precious metals such as gold and silver (within 1kg), melting time less than 5 minutes.

Energy saving: compared with traditional crucible furnaces, energy consumption is reduced by 40%.

Laboratory melting: small melting experiments for alloy composition analysis by the School of Materials of universities.
