Deep cold box is used in meatl processing after quenching. Using liquid nitrogen (-196°C) as cooling medium,  makes a fully transformation from austenite to martensite. After deep cold treatment , the hardness, abrasive resistance, service life of milling cutter will be greatly enhanced.

Application: Roller,bearing,milling cutter, drill, mold, and many HSS tools, alloy.

                    valve, spring, and many metal parts of precise machine

Features of our products:

1.Various in type: horizontal, vertical, square, circle, etc. We can also design and manufacture according to your special requirements

2.Fast speed of cooling: the Maximum cooling speed ≥ 20°C/min

3.High precision of temperature control: Using Touch screen and PLC control systerm, the Temperature can be set as your wish.

4.Uniformity of temperature field is ± 2 °C.

5. Using the latest liquid dispersion technology. The consumption of liquid nitrogen is quite low.

we are looking for cooperator in oversea market, maybe it is a good opportunity for both sides.
