Temperature and atmosphere uniformity: Positive and negative pressure paraffin removal or PEG integration sintering uniformity: furnace control piece (Brand YC40 or YG6 medium granular), evenly distributed.
The buyer shall provide the furnace control piece and the procedure, and the seller shall confirm it.
Cobalt magnetism: testing cobalt magnetism after finished dewaxing
Deviation range:≤±0.2%
Coercive force:
Deviation range:≤±0.3KA/M
The temperature uniformity in the furnace is mainly based on the test performance of the furnace control piece.

Vacuum Sintering Furnace Applications
For Cemented Carbide, Precision Ceramics, stainless steel, Iron-based alloy, Copper-based alloy, Aluminum products
The cemented carbide pressure sintering furnace is a single chamber and double door horizontal and periodic heating structure,which is designed for easy handling and maintenance, the whole process is controlled automatically.It can realize full load continuous operation, 300 furnace times/year or 300 working days/year.It uses graphite element resistance heating (low voltage, high current) .In addition, there are multiple heating units, each of which controls the temperature separately.It equipped with fully automatic control function and safety interlock function.The whole process is automatically controlled, monitored, tracked and recorded by computer.The PLC, industrial computer (IPC) control to realize the whole process of one-key start, real-time dynamic monitoring, computer will save temperature, pressure, vacuum and other parameters ,alarm interlocking is safe and reliable.
