Vacuum furnace graphite seal
Jincheng Graphite, as a professional source manufacturer of graphite products, provides high-temperature resistant and high-sealing performance vacuum furnace graphite seals. These are specially designed for high-temperature and high-pressure working conditions, featuring advantages such as anti-deformation and corrosion resistance. They are widely used in semiconductor, chemical engineering and other fields.
Core Advantage
Excellent material performance
Utilizing high-purity graphite as the base material and combining with low-temperature sintering technology, it ensures that the sealing components maintain structural stability at a temperature of 2500℃, eliminating the risk of thermal stress cracking.
Reliable sealing performance
The surface has undergone nano-coating treatment, enhancing the anti-permeation ability, effectively preventing gas leakage and ensuring the stability of the internal environment of the vacuum furnace.
Customization and adaptation
Jin Cheng Graphite provides a full-process service from design to production, supporting the customization of sealing component sizes, shapes, and sealing groove structures according to customer requirements, and adapting to the mainstream vacuum furnace equipment worldwide.
Application Scenario
Vacuum furnace graphite seals are widely used in semiconductor wafer heat treatment, chemical reaction vessel sealing, vacuum coating equipment, and other scenarios. Their excellent high-temperature resistance and sealing stability can significantly extend equipment lifespan, reduce maintenance costs, and enhance production efficiency.
