Handheld Ultra-High Frequency Heating Equipment

Handheld ultra-high frequency heating equipment is a portable, compact induction heating device operating at ultra-high frequencies (typically 100 kHz to 2.0 MHz). Designed for manual operation, it integrates core induction heating technology into a lightweight, easy-to-maneuver structure, making it ideal for on-site, localized heating tasks.

Key Features

  • Portable Design: Lightweight (often a few kilograms) with an ergonomic grip, allowing operators to handle it comfortably for extended periods. The handheld probe or coil enables precise targeting of small or hard-to-reach areas.
  • Ultra-High Frequency Operation: Delivers rapid, localized heating with shallow penetration (usually less than 0.5 mm), perfect for small workpieces or surface treatments without affecting the core material.
  • Instant Heating & Cooling: Reaches set temperatures quickly (in seconds) and cools down rapidly after use, improving work efficiency and reducing waiting time.
  • Digital Control: Equipped with a user-friendly interface (e.g., touchscreen or knobs) to adjust power, heating time, and temperature, ensuring precise control over the heating process.
  • Safety Features: Includes overcurrent protection, overheating shutdown, and low-voltage output to ensure operator safety, even during prolonged use.

Typical Applications

  • Small-Part Welding/Brazing: Joining tiny metal components such as stainless steel wires, copper terminals, or jewelry parts.
  • Localized Quenching: Hardening surface layers of micro metal parts (e.g., precision gears, tool tips) to enhance wear resistance.
  • Repair & Maintenance: On-site heating for tasks like loosening rusted bolts, removing paint or coatings, or shrinking fittings.
  • Laboratory Use: Precise heating of small samples for material testing or research.

Advantages

  • Flexibility: Eliminates the need for fixed workstations, adapting to diverse on-site or mobile heating needs.
  • Precision: The narrow, focused heating zone minimizes thermal damage to surrounding areas, critical for delicate components.
  • Efficiency: Direct energy conversion reduces heat loss, saving energy compared to traditional flame heating methods.
