Easy Maintenance Gas Pressure Sintering Furnace With Patented Dual Fast Cooling Structure
Description:
gas pressure sintering furnace is single-chamber, horizontal and periodic heating. It adopt low voltage and large current graphite heating element to heating, and it has multiple heating units, each unit controls the temperature separately. The whole process is automatically controlled, monitored, tracked and displayed and recorded by the computer.
Quality Advantages
Low temperature uniformity test is carried out to ensure the high quality of gas pressure sintering furnace. 6 thermocouples are arranged in the furnace.
(1) Test conditions of vacuum dewaxing or flowing gas dewaxing
Test temperature: 280°C, 335°C;
Keep the temperature constant within 180 minutes;
Tolerance of 6 thermocouple reading: ±5°C.
(2) Test condition of vacuum sintering
Test temperature: 600°C, 800°C, 950°C;
Keep the temperature constant within 180 minutes;
Tolerance of 6 thermocouple reading: ±5°C.

Technical Advantages
1. A filter is designed on the main line of the vacuum-pressure sintering furnace to effectively protect the vacuum pump and extend the oil change interval of vacuum pump.
2. This gas pressure sintering furnace adopts patented dual dewaxing outlet structure (patent No.: ZL2013 2 0422916.7). Compared with single dewaxing outlet design of other brands, our pressure sinter furnace enjoys better atmosphere uniformity when sinters ultra-fine cemented carbide with low cobalt.
3. Our patented dual fast-cooling structure (patent No.: ZL2013 2 0422878.5), compared with single fast-cooling structure of other companies, helps effectively improve the efficiency of the vacuum-pressure sintering furnace.
4. Newly-designed dewaxing system with additional gas distribution pipe (patent No.: ZL2013 2 0471657.7) allows enhanced atmosphere uniformity (97%) during the dewaxing process.
5. We adopt tapered sealing structure (patent No.: ZL2013 2 0422133.9) on both ends of the sintering chamber for improved sealing effect of furnace door, less heat loss, and ease of replacement and maintenance.
