The ability to produce Heat Treated apparent hardness levels directly from the sintering process has proven to be a benefit in many applications. Although the grade of PM materials used is more expensive than standard PM materials, the process has its advantages that offset the additional cost of a sinter-hardening grade of material. The normal oil quench heat treat process has drawbacks that include distortions that can inhibit the ability to produce a flat part or control tight tolerances without additional processing costs. Tighter tolerances and flatness can be achieved through the sinter- hardening process due to the elimination of the somewhat “non-uniform” oil quench. Quenching by using the furnace’s atmosphere provides less of a shock to the part and the quench uniformity can be better controlled.


Your Answer To Sinter-Harding


The proprietary design of the HyperCooler’s impinging jet array technology ensures cross belt uniformity preventing part-to-part variation in both hardness and dimensional control. The impinging jet geometry is specifically designed to insure a rapid and uniform cooling rate that is FIVE times faster than standard forced convection heat transfer. The HyperCooler is fast and easy to set with only one adjustment to be made, blower speed. There are no baffles to adjust that can mess with atmosphere flows and complicate the setup process. The unit is easily retrofitted to an existing sintering furnace. It takes up no additional floor space outside of the normal width of the furnace.

Uniformity control


Sinterite’s HyperCooler provides an excellent uniform rapid-cooling solution while minimizing product variation!
Cooling rates of up to 8 degrees F per second have been achieved while maintaining excellent across belt uniformity.
