PVA Industrial Vacuum Systems GmbH

With our COD pressure sintering systems, you can achieve top cemented carbide quality over and over again. The systems combine two technologies in one machine: Vacuum sintering and hot isostatic pressing of sintered parts.

In addition to the standard pressure ratings of 60 bar and 100 bar, pressure sintering systems with process pressure of 200 bar are available for extremely low-cobalt types of cemented carbide. There is also a special high-temperature version of our pressure sintering systems available, and it is perfect for manufacturing silicon nitride ceramics.

Largely standardized and cost-optimized SSH pressure sintering systems are available for basic applications.

Our COV vacuum sintering systems enable cost-optimized manufacturing of cemented carbide materials, non-oxide ceramics, and other composites. The systems have a modular design, which allows them to be adapted to meet customers’ needs for specific sintering tasks. Various debinding technologies open up the possibility of using a wide range of binders. MOV vacuum sintering systems with metal heating elements are an option for carbon-sensitive applications.

These are electrically heated batch systems for standard and high-temperature brazing processes. The typical design temperature is 1,300 °C, but can reach 1,700 °C in some cases. For vacuum brazing applications, PVA offers two different product series that differ primarily in terms of the design of the heating element and the vacuum pump. PVA brazing systems for industrial production processes generally have active gas cooling units for rapidly cooling brazing batches to room temperature and therefore help to make processes extremely efficient.
