High temperature vacuum furnace with single-chamber, horizontal and periodic heating, heated by low-voltage.
The special sintering furnace for cemented carbide is single-chamber, horizontal and periodic heating, heated by low-voltage and high-current graphite heating element, with multiple heating units, each unit individually controlling the temperature.The whole process is controlled by computer automation, monitoring, tracking, fault self-diagnosis simulation display and record.
Design standard: double door horizontal structure, horizontal structure design for easy handling and maintenance, the whole process automation control.
Adopt the graphite inner structure inside the insulation tube.On the whole, it must meet the strict requirements of furnace temperature uniformity and atmosphere uniformity in the sintering process of precision cemented carbide.Main supporting components (control elements, sensors, graphite heating element, thermocouple, main control valve, vacuum pump, etc.) have the international advanced level, can adapt to long-term, stable, reliable mass production requirements.At the same time, the equipment should also meet the national requirements for energy conservation and environmental protection.
It is suitable for the degreasing of high performance cemented carbide materials (can realize the negative pressure dewaxing process, the molding agent is paraffin), hydrogen positive pressure dewaxing, vacuum sintering, partial pressure sintering, rapid cooling and other batch production operations and laboratory research and development.Sintered carbide products, ceramic blade products, extrusion products and special products.

1.Installation, Commissioning And Acceptance
We do installation, commissioning and acceptance in buyer's plant.During the installation and commissioning period, the commissioning personnel shall be provided free of charge by the demander according to the staff standard.
The equipment shipped to the buyer, the seller received the buyer's notification, both within a week to carry the equipment out of the box together, then check the equipment and all components according to the packing list . Including equipment accessories, spare parts and special tools, attached manual and technical documents, etc. It can be installed after the acceptance check of equipment.
After installation and debugging, the equipment shall be accepted according to the technical accessories.
When taking-over the Furnace to the customer, We will give a staff training to customer. The operating personnel of the customer should join to commission,test the furnace, when installing at customer’s company.
This is practical operation training and practical maintenance training,
and our technical personnel will telling the basic principle,equipment maintenance knowledge,And the common fault handling measures.We can training 2 ~ 3 workers. ( Training how to maintenance and operating.)
3. Warranty period
The warranty period of the equipment is 12 months, which starts from the date of installation and debugging of the supplier. Equipment failure happens, after-sales service personnel shall give solutions within 2 hours, after receiving the buyer's notification . If it is need to go to the site for treatment , operators dispatched by seller should arrive at the site within 48 hours after go aboard. In case of emergency,operators should arrive at the site within 48 hours after go aboard, and continue to make repairs until the fault is removed and the equipment returns to normal.
We are a professional manufacturer of powder metallurgy sintering furnaces. Custom design is available according to customer’s requirements. Please offer us the sintered material, size of sintered piece, max. temperature, heating zone dimensions, vacuum level and other special requirements when making inquiries. We will offer professional proposal and solutions based on your requirements.
Quality assurance and service:
1. Our company guarantees that all materials and purchased components meet the national technical quality standards.
2. Within one year from the date of acceptance of the equipment, if there is any quality problem caused by the design or manufacture of the equipment, our company will carry out free maintenance and bear the maintenance cost.If the equipment exceeds the warranty period or is damaged due to human error or force majeure (such as natural disaster), our company will actively provide high-quality paid service.
