Featured with resistance heating, PID intelligent temperature control & 24-hour time switch, this machine is used for the heat treatment of jewelry, K gold jewelry, copper, silver, wires, and plate stamping parts.

Through the effect of protective gas, the surface of the workpiece is highly bright and colored without oxidation, the stress is removed, and the common standard is realized.

The machine is equipped with a high-performance ammonia decomposition and hydrogen production system, which is the good assistant of oxidation-free heat treatment.
