Classification and characteristics of vacuum hot pressing sintering furnace

Air hot pressing sintering furnace is a kind of heat treatment equipment for hot pressing sintering under vacuum environment, which is mainly used for densification and sintering of powder metallurgy materials. According to different sintering methods and structural forms, vacuum hot pressing sintering furnaces can be divided into the following categories, and have their own characteristics:

1. Hot press sintering furnace: Hot press sintering furnace is the powder material placed in the mold, under the action of heating and pressure sintering. It is characterized by high temperature, high pressure and high density sintering process, which is suitable for the preparation of high-performance ceramics, metals and alloy materials.

2. Vacuum sintering furnace: Vacuum sintering furnace is a equipment for sintering in a vacuum environment. The vacuum environment can effectively remove oxygen and other harmful gases, avoid oxidation and pollution of the material, and thus improve the purity and density of the material.

3. Vacuum hot pressing sintering furnace: vacuum hot pressing sintering furnace is a combination of hot pressing sintering and vacuum sintering equipment. It can not only achieve high temperature and high pressure sintering process, but also can be carried out in a vacuum environment to ensure the purity and density of the material.

4. Hot isostatic sintering furnace: Hot isostatic sintering furnace is a kind of equipment that places powder materials in a mold and applies static pressure to sintering at high temperature and high pressure. It is characterized by high density, high density and high uniformity of sintering, which is suitable for the preparation of high-performance ceramics and composite materials.

Features:

1. High temperature stability: the vacuum hot pressing sintering furnace has good high temperature stability, which can provide a stable sintering environment at high temperatures to ensure the consistency of the sintering process.

2. High pressure capacity: vacuum hot pressing sintering furnace can provide high pressure, so that the material in the sintering process to obtain higher density and strength.

3. Pure environment: vacuum hot pressing sintering furnace can provide a pure sintering environment, remove oxygen and other harmful gases, avoid oxidation and pollution of materials, and improve the purity of materials.

4. High density: The vacuum hot pressing sintering furnace can achieve higher density and uniformity of the material under the action of high temperature and high pressure, and improve the performance of the material.

5. Precise control: vacuum hot pressing sintering furnace is equipped with advanced control system, which can achieve accurate control and automatic operation of temperature, pressure, time and other parameters.

It is necessary to select the appropriate vacuum hot pressing sintering furnace according to the specific material and process requirements, and operate in strict accordance with the operation manual and relevant regulations to ensure the safety and effectiveness of the operation
