product_detail
Graphite columns are the main load-bearing support components inside vacuum furnace hot zones, holding graphite plates, boats and heating assemblies stable at ultra-high temperatures. Dongguan Jiecheng Graphite Products Co., Ltd. supplies custom graphite columns for thermal processing and sintering equipment.
Key Features
Graphite columns feature high compressive strength, low thermal expansion and excellent thermal shock resistance. They maintain stable dimension under repeated heating and cooling, with low outgassing for high-purity grades. Good chemical inertness prevents reaction with protective gas such as nitrogen and argon. Isostatic graphite columns deliver uniform performance in all directions for heavy-load applications.
Typical Applications
- Vacuum sintering furnace thermal field support
- Powder metallurgy and MIM sintering lines
- Ceramic and silicon material sintering furnaces
- Brazing and vacuum heat treatment furnaces
- Sapphire and optical crystal growth equipment
Graphite columns can be machined with threaded ends, step shoulders and positioning grooves according to drawings. Jiecheng Graphite produces graphite columns on five-axis CNC machines and provides material test reports for density, purity and compressive strength.
