Vacuum Furnace Systems
Vacuum furnace systems allow for high temperature processing in fully controlled oxygen-free environments. The hot zone of the furnace is contained entirely within a sealed water-cooled vessel which allows for a controlled atmosphere with minimal insulation to reduce cool down time of the system. Vacuum furnaces provide high consistency and low contamination for annealing, brazing, sintering, and heat treatment processes.
ob体育比分 specializes in premium equipment for customers that demand the highest level of temperature and environmental control within their furnaces. With an average furnace lifetime of 20+ years our customers are long-term partners that we continue to support for the lifetime of the equipment.

Hot Zone Materials
The material of the hot zone typically determines the application and operating conditions of the furnace, the two main materials are either graphite or refractory metal systems. Graphite hot zone vacuum furnaces are the most common in industry as they are durable and low cost, however for materials and applications that demand a truly clean environment refractory metal hot zone vacuum furnaces are the preferred alternative.

Molybdenum & Tungsten Vacuum Furnaces
High temperature vacuum furnaces require the use of refractory metals for the hot zone materials. These hot zones enable production at higher temperatures with sustained durability, and flexibility of application. Two of the most common refractory metals used today are Molybdenum and Tungsten.
| Hot Zone Material | Maximum Temperature | Typical Applications |
| Graphite | 3,000°C | High temperature sintering, heat treatment |
| Molybdenum | 1,800°C | Powder metallurgy, diffusion bonding |
| Tantalum | 2,500°C | Processing Electronic materials |
| Tungsten | 3,000°C | Sintering and heat treating carbon sensitive materials |
