Product Features and Special Configuration

Mainly used in stainless steel base, hard alloy, high temperature alloy, high specific gravity alloy, cermet, magnetic material, carbide, boride, oxide, intermetallic compound, vacuum before vacuum sintering or carrier gas degreasing (wax) High temperature sintering. Our company can also order vacuum or carrier gas degreasing (wax) vacuum degreasing furnaces for materials.

Uniform heating, reliable insulation and temperature measurement:

  • Reasonable heating structure, excellent material, to ensure the uniformity of furnace temperature under vacuum.
  • Adopt brand temperature measuring components to accurately measure temperature.

Superior degreasing effect:

  • Degreasing sealed furnace and fat trap, no internal furnace wall, heat shield and heating body pollution, degreasing and grease collection is more effective, sealing furnace is conducive to improve furnace temperature uniformity.
  • Directional airflow degreasing, enhanced degreasing effect, no dead fat in the furnace, and more complete degreasing.
  • The pressure control in the furnace realizes micro-negative and constant-pressure sintering, inhibits metal volatilization, and improves product compactness and quality.

Thorough steam cleaning system:

  • Equipped with a unique vapor clearing system to eliminate grease troubles.

Advanced automatic control and reliable safety interlock:

  • It adopts computer to realize automatic control of temperature and action process, PLC realizes safety interlocking, and has sound and light alarm and interlocking work ability such as overpressure, over-temperature and high temperature.

Fast cooling system to increase production efficiency:

  • Equipped with an internal circulation rapid cooling device, the high-efficiency heat transfer technology blows the workpiece in multiple directions, and the cooling is fast and uniform.
  • Compared with the external circulating rapid cooling device, it has the advantages of small footprint, small area, high starting temperature and fast vacuum pumping speed.

Equipment technical characteristics:

  • The sintering furnace adopts special hot zone structure and heating element design to ensure good temperature uniformity.
  • Using a specially designed dewaxing device, sealed well, removable, which can effectively prevent the internal components of pollution;
  • Equipped with vacuum sintering, micro positive pressure sintering, partial pressure sintering, micro-vacuum degreasing and micro-positive pressure degreasing function;
  • The furnace with temperature, pressure, water pressure, vacuum and other interlocking features, with a high degree of safety protection and prevention functions;
  • With remote control operation, remote fault diagnosis and remote program updates and other functions;

Optional configuration
