Products Description
This fast cooling powder metallurgy sintering furnace features a built-in forced convection cooling system that activates immediately after sintering. Achieve "sinter-hardening" in one step — high-strength and high-hardness PM parts come directly out of the furnace, eliminating post-heat treatment and reducing overall costs by 25-35%.

What is a Fast Cooling Powder Metallurgy Sintering Furnace?
A fast cooling powder metallurgy sintering furnace is a specialized industrial furnace that cools PM parts at a controlled, high rate immediately after the sintering cycle is completed.
Unlike traditional sintering furnaces that allow parts to cool slowly and naturally, this equipment integrates a rapid cooling system that achieves fast temperature reduction through:
1.Media Cooling: Recirculating process gas (nitrogen, argon, or hydrogen-nitrogen blends) is introduced into the furnace.
2.Heat Exchange: Hot gas carrying part heat passes through a water-cooled heat exchanger, transferring heat to the external cooling water system.
3.Forced Circulation: Cooled gas is blown back at high velocity onto the part surfaces, creating forced convection that efficiently removes heat.
The result: Parts exit the furnace having already completed their metallurgical transformation — fully hardened and ready for use, with no need to go through a separate heat treatment department.
How It Works
Typical Process Flow:
Loading → Dewaxing (Lubricant Removal) → High-Temperature Sintering (up to 1250°C) → Fast Cooling (3-20°C/sec adjustable) → Unloading (Already Hardened)
