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.

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 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 vacuum-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.

Experience Advantages
1. We have been engaged in designing and manufacturing furnaces for more than 15 years.
2. Commissioning experience of hundreds of sinter-HIP furnaces.
3. We have a professional team that is capable of completing installation and commissioning within 25 days if water, electric and gas are ensured.

After-sales service
1. We provide technical support and professional solutions according to your production process.
2. We will be responsible for the liability related to intellectual property rights arising from or in connection with the design, manufacturing, sales and operation of the vacuum-pressure sintering furnace. Customers will not be responsible for such liability.
3. We offer 12-month warranty for this sinter-HIP furnace. If equipment failure happens, our after-seals personnel will respond within 24 hour after being notified, and if on-site assistance is required, our personnel will arrive at the site within 48 hours. They will check and repair the equipment until it works normal again.
4. If any loss or damage arises during the warranty period from equipment quality, we will offer free replacement or repair. If it’s not due to quality, or it’s caused by customer’s negligence or improper operation, customer can contact us for paid technical assistance.
