Multifunctional Intelligent Sinter HIP Furnace For Vacuum / Pressure Of Hard Alloy Materials
1. All these gas pressure sintering furnace are equipped with double control system, double thermocouples and double high pressure sensor to ensure that if one system fails, the other will continue to work reliably.
2. We use German COAX high-pressure valve, Germany WAKI high-pressure sensor and Germany LEYBOLD or INFICON vacuum gauge for safe and reliable operation, high vacuum level and low vacuum leakage.
3. Each of these 10bar gas pressure sintering furnaces is detected by using helium mass spectrometer leak detector.
1. A filter is designed on the main line of the 100bar gas pressure sintering furnace to effectively protect the vacuum pump and extend the oil change interval of vacuum pump.
2. This 10MPa sinter-HIP furnace adopts patented dual dewaxing outlet structure (patent No.: ZL2013 2 0422916.7). Compared with single dewaxing outlet design of other brands, our 100bar gas pressure sintering 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 sinter-HIP 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.
