The HIQ series vacuum hot press sintering furnaces are used for sintering of metal powder products, photoelectric components, hard alloys, magnetic alloys, ceramics, powder materials and other rare and refractory metal materials, and meanwhile have certain dewaxing function.

Applications 

Main Purpose

Vacuum hot-pressing sintering furnace is a combination of vacuum/atmosphere, hot-pressing and high-temperature sintering, which is suitable for high-temperature hot-forming of new materials, like powder metallurgy and functional ceramics. It applies to the transparent ceramics, industrial ceramics and other metal and vacuum sintering of compound of refractory metal alloy material and silicon carbide and silicon nitride ceramic material of high temperature sintering, and can be used for heat treatment of powder or compact shape under the temperature below the melting point. The purpose is to improve its strength through the metallurgical bonding between the particles.

1. Furnace body: double layer 304 stainless steel water-cooling structure, precision polishing, which is conducive to shorten the extraction time, and is easy to clean;

2. Furnace cover: double-layer water-cooled structure, with 304 inside and outside walls and precision polishing treatment, and cooling water in the middle.

3. Heating, heat preservation and temperature measurement system: the heating system uses graphite cylindrical heater to not only guarantee the best temperature uniformity and the artifact of uniform heat, but facilitate the maintenance and replacement of heating elements. The heat insulation screen on the side and the bottom is made of a composite insulation layer composed of hard felt and soft felt, which is processed into an integral heat insulation system. The machine adopts Silicon controlled to control temperature , equipped with PID function instrument, digital display meter, with over temperature sound and light alarm function. It can also choose PLC touch panel to achieve automatically control, and retain historical data to be easy to analyze the sinter process.

4. Vacuum system: it is composed of oil diffusion pump, roots pump, mechanical pump equipped with electromagnetic differential pressure valve (to prevent sudden power failure and mechanical pump oil backward), filling valve, air release valve, vacuum butterfly valve, vacuum pressure gauge (Pa), corrugated pipe, vacuum pipeline and support, etc.

5. Inflation system: it is composed of various pipelines and valves, equipped with electromagnetic deflation valve and pressure sensor. It will automatically discharge gas When the pressure in the furnace is higher than the security value. Needle valve is installed on the gas tube, which can control the inflating volume, and is used to fill argon and nitrogen in the atmosphere required for sintering process.
