Bottom Discharge CVD/Carbonization Furnace

Equipment Use: Primarily used for CVD and CVI processes to produce high-performance composite materials such as C/C, C/SiC, and SiC/SiC. Core Advantages: The bottom-loading/unloading structure design greatly facilitates the handling of large-sized, heavy carbon workpieces and enables continuous production, with a maximum design temperature of 2100°C. Technical Support: Features isostatic graphite resistance heating with low-voltage, high-current control, equipped with a Siemens PLC and a 15-inch touch screen, supporting fully automatic process programming and data export.
Product details

Overview

Chemical Vapor Deposition (CVD) is a process in which precursor gases undergo thermal decomposition to generate reaction products that deposit onto a substrate, forming thin films or densifying the matrix. The bottom-discharge CVD/Carbonization Furnace developed by Yuanhang Industrial Furnace is specifically designed for applications such as carbon/carbon (C/C) composites and silicon carbide (SiC) coatings, serving as the core key equipment for achieving densification of high-performance materials.
