Gas Pressure Sintering Furnace

Description
Gas pressure sintering furnace is mainly used for vacuum sintering and pressure sintering of Sic, Si3N4 and other ceramic parts.

Technical Features
1. This horizontal sintering furnace adopts special hot zone structure and heating element design for good temperature uniformity.
2. It uses specially-designed debinding muffle to realize excellent sealing performance, complete bind removal and no contamination to inside components.
3. This gas pressure sintering furnace has functions of slow vacuum, minor positive pressure sintering, partial pressure sintering, pressure sintering, minor negative pressure debinding and minor positive pressure debinding.
4. It uses advanced refractory materials and structure for ensured insulation.
5. This horizontal sintering furnace is designed with touch screen and PLC central control for ease of operation.
6. Safe performance is ensured with over-temperature and over-pressure mal-function alarm, mechanical automatic pressure protection and interlocking.
7. The gas pressure sintering furnace has functions of remote control, remote mal-function diagnosis and remote program update.
