Vacuum chamber furnace with metal insulation

Achieve high-temperature processing with precision and purity using advanced vacuum technology, ideal for enhancing sintering, debinding, and thermal processing of metal and ceramic components.

Controls High-Temperature Sintering and Debinding Processes

The HTK series from Carbolite Gero offers vacuum chamber furnaces with metal insulation, specifically designed for high-temperature applications up to 2200°C. This range is distinguished by its use of tungsten or molybdenum, ensuring a pure atmosphere and precise control over debinding and sintering processes. These furnaces are essential for producing high-performance ceramic components, metalized electrical contacts, and tungsten carbide cutting tools. Available in sizes ranging from 8 to 120 liters, they support both laboratory research and pilot manufacturing. The furnaces are PLC-controlled for seamless integration into automated production lines and offer high vacuum capabilities, ideal for aerospace, automotive, and electronics industries. They also feature energy-efficient thermal insulation and a choice of atmospheric gases, enhancing operational versatility and efficiency.
