Equipment for Producing Silicon Carbide Ceramics Introduction

---

Shanghai Gehang Vacuum Technology Co., Ltd. mainly produces reactive

sintered silicon carbide, pressure-less sintered silicon carbide and its derivatives. It has domestic advanced production processes such as pressureless sintered silicon carbide, reactive sintered silicon carbide water-based spray granulation, and fully automatic press molding. . It mainly produces four major application areas including sealing rings, shaft sleeves, bulletproof armor, nozzles and wear-resistant parts. Widely used in petroleum, chemical, automotive, military, paper, sewage treatment, food, pharmaceutical, nuclear industry and other fields.

SIMUWU company has also developed a high-temperature vacuum sintering furnace, which is used in the production of silicon carbide, silicon nitride and powder metallurgy industries.

Regarding to the production of silicon carbide materials and related process equipment are introduced as follows, hoping to be useful to all customers.

Structure

Dry pressing machine hand wheel, dynamic pressure wheel, constant pressure wheel, cycloidal pin wheel, reducer, motor, etc. Suitable for pressing ceramics, magnetic materials and other materials. This machine has a high degree of automation, and has the characteristics of saving materials, labor, time, and multi-purpose while improving productivity in safe production. It is the first choice for dry-pressed ceramic and magnetic material molding machines. The machine has high precision, stable tableting, good performance and high yield. The fully automatic ceramic forming machine produced by Jingrei Machinery Factory is controlled by PLC. The time of each action is input through text and all can be adjusted. It can be automatically demolded, and the gate can be cleaned automatically without manual cleaning. Standardized mold base design, automatic mold matching, so that the mold replacement time is shorter.
