Multi-Function Heating Treatment FurnaceSAM

Quenching and Annealing under the right conditions for each type of steel improves material hardness, reduces distortions and extends die life. With SAM, HIROCHIKU provides solutions to your heat treatment problems.

Target Works (Typical Examples)

Heat Treatment Methods

Quenching and annealing


  1. Dies
    • Cold work tool steel:
      Caulking, deep drawing, forging, dies, stamping, etc.
    • Hot work tool steel:
      Die-casting, casting molds, forging, dies, etc.
    • High-speed tool steel:
      Drills, end mils, taps, reamers, etc.
    • Molds for plastics:
      Injection molds, etc.
  2. Tools and jigs
    Probes, collet chucks, punches
  3. Parts
    Gears, springs, clutches, bearings, screws, chains, etc.
  4. Products
    Latch needles, fish hooks, pocket knives, kitchen knives, saws, etc.


Quenching oil-quenched, nitrogen-gas-quenched and high-speed steel can be performed by a single unit.

Space-saving installation.

Easy automated operation using programs.

Six-panel heater ensures excellent temperature distribution.

Muffleless structure and unit heater enable easy maintenance.
