Heat Treatment Equipment

Heat treating is a thermal process used to alter the physical properties of metals. By changing the rate of heating or cooling, normally to extreme temperatures,  to achieve a desired result such as hardening or softening of a material.  Heat treatment techniques include annealing, case hardening, precipitation strengthening, tempering, normalizing and quenching.

The process of heat treating metals involves mostly heating subsequently rapid quenching and annealing and can be achieved with continuous or batch processing furnaces. We build these heat treat furnaces either with electric heating or direct or indirect fuel fired heating systems.

Solution heat treatment of all kinds workpiece can be done in cooldo furnace as below:
– Box/Chamber Furnace
– aluminum solution heat treat furnace
– Mesh Belt Conveyor furnace
– Continuous Mesh Belt Conveyor Muffle Furnace
– Car Bottom Heating Treatment Furnace
