Using specialized vacuum pumping systems, binder traps and condensers, plus engineered gas delivery systems, AVS Sinter HIP furnaces provide closely controlled vacuum, partial pressure and HIP atmosphere control from vacuum up to 150 bar. If required, temperatures can be managed by multiple zone heating and control for superior uniformity and product quality. Six sided heating (top, bottom, left, right, front and rear) is commonly used to minimize heat gradients and maximize load capacity.
AVS offers standard Sinter HIP furnace sizes for tungsten carbide from 1ft³ volume to 20ft³, operating up to 1600°C at 60 bar or 100 bar of argon, with available Rapid™ Cooling systems, load transfer systems, hydrogen burn-off capabilities and gas recovery systems. The unique willingness of AVS to build custom pressure furnaces, applying high temperature and HIP furnace innovations, has enabled customers to pursue novel combinations of pressures up to 150 bar, and temperatures up to 2300°C.
With the standard cooling package, an AVS Sinter HIP furnace with a nominal load can cool for unloading in approximately 7 to 8 hours. On the other hand, the same furnace with the same load is able to cool in less than 4 hours if equipped with an AVS Rapid™ Cool system. Rapid™ Cool is available on all new AVS Sinter HIPs, but can also be retrofitted to existing Sinter HIPs in the field.
