Sinterbar™ 800

CVI pressure furnaces are used for a variety of processes associated with the production of hard metals and ceramics. Full densification with limited additives and conventional zero A of TRS, toughness and grain growth tradeoffs;

The Sinterbar™ 800 is fully capable of complete combination cycles incorporating delube, vacuum sinter and pressure sinter. Partial pressure control, flowing atmosphere control, flowing atmosphere control and reactive gas management are typical features.

The Sinterbar™ 800 is a large load furnace robust enough for "large piece" type runs and thermally tight enough to accomplish large insert runs.

Features:

6 independent zones of thermal control
Run to run repeatability and excellent uniformity for all process cycle sub-sections: delube, vacuum sinter and pressure sinter
Robust Cooling Enhancement
The furnace design has been modified to achieve rapid cooldowns without the addition of high maintenance items like fans, shutters and retort connectors; The furnace actuates both doors sections (retort and insulation) partially open and allows the hot pressurized gases to use their enormous free convecting energies. The product sees direct forced convection.
Unique delube and improved vacuum flow conductance
Faster more repeatable delube cycles while minimizing that "cold spot" effects typical of most sintering furnaces that utilize retorts. The bottom insulation pack and delube ports are integrated as a single piece incorporating both radiant deflection and thermal insulation.
Improved convection interference
Better uniformity and lower energy consumption
Stainless steel inner and outer jackets
Very long useful lifetimes, minimized water degradation concerns
Improved feed-thru design
Mean time to repair (MTTR) and Mean time to failure (MTTF) improvements

Control Strategy
CVI works with two basic control strategies:
A more conventional PLC based control system with Programmable, event based controls or a more capable, fully integrated PC based control system:

PC Based Control

Pentium Based PC workstation
Intellution based architecture for DDL
Full Data Acquisition Capability
Custom Reporting
Remote System operation / System Multitasking
Turnkey electrical integration

PLC Based Control

Programmable, event based control
PLC for trouble free system interlocking logic
Discrete controls for individual sensors with communication
Turnkey electrical integration
Optional remote interface
