TH-1 annealing machine can raise the metal tubes’ temperature quickly by inputting low voltage but large electric current, and then cool them in the air after the power is off. The purpose of annealing is realized in this way.

TH-1 annealing machine is one of the major equipments for manufacturing heating tubes. The extension rate of the annealed part will be raised so that the tubes could be easily bent. The sheath material could be ranging from common carbon steel, stainless steel, copper to aluminum.
