6MPa Vacuum Pressure Furnace Pressurization Period 15-30 Min Vacuum Leakage Rate 3Pa/H
Description
This 6MPa vacuum-sintering furnace offers unprecedented value to applications that require sintering furnace technology for cemented carbide and precision ceramic. Quality, efficiency and reliability are just a few of the outstanding attributes that have allowed Ruideer to become the premier supplier of sintering furnaces.
Features
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 6MPa vacuum-pressure sintering furnaces is detected by using helium mass spectrometer leak detector.
Quality Advantages
Low temperature uniformity test is carried out to ensure the high quality of sinter-HIP 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.
Suitable products to sinter:
Cemented carbide,mental ceramics,ceramics,MIM(Metal injection molding) products, Iron-base alloy, Copper-base alloy, Aluminum etc.
