Vacuum Debinding and Sinter Furnace

Description
Vacuum debinding and sinter furnace is mainly suitable for debinding and sinter process of tungsten alloy, heavy alloy, moly alloy, titanium alloy and cemented carbide materials. The vacuum debinding sitering furnace is used for PEG, paraffin and rubber binder removing. It can also do vacuum sinter, partial pressure sinter and minor pressure sinter processes.
 
Technical Features
1. Special designed debinding muffle is adopted with good sealing and complete bind removable, preventing inside components pollution.
2. It has functions of slow vacuum, vacuum pre-sinter, minor negative pressure debinding, TOWAC debinding and minor positive pressure debinding.
3. The furnace adopts advanced refractory structure and materials, which features good insulation performance and less heat absorption. It can save more than 20% energy compare o previous design.
4. Vacuum debinding and sinter furnace works by using touch screen operation and PLC central control, which makes the operation simple and reliable.
5. The vacuum debinding sitering furnace uses special hot zone structure and heating element design, assuring good temperature uniformity.
6.The furnace has the functions of over temperature and over pressure fault alarm, mechanical automatic pressure protection and interlocking, which forms a highly safe furnace.
7. It has remote control operation, remote malfunction diagnosis and remote program update functions.
