Equipment system
It mainly includes control system,heating system,positive and negative pressure vacuum system,cooling water system, rapid cooling system,safety system and auxiliary system.
Painting:
The surface of furnace body, transformer, control cabinet and vacuum pump is light gray (color code: RAL7035). The furnace foot, pump frame and support are matched by sky blue (color code: RAL5015).The groove is stainless steel, the support is galvanized, the transformer is placed on the ground.
General equipment requirements:
The equipment is mainly used for stainless steel(MIM),debinding of cemented carbide (vacuum Ar carrier gas debinding and hydrogen micro-positive pressure debinding), vacuum sintering, partial pressure sintering, pressure sintering, rapid cooling and other processes.It can meets the strict requirement of uniformity of furnace temperature and atmosphere in sintering process of cemented carbide.The furnace structure design is advanced and reasonable, easy to use operation and maintenance.The main supporting components (control components, sensors, graphite heating element, thermocouple, main control valve, vacuum pump, etc.) have the international advanced level, can adapt to the long-term, stable, reliable batch production requirements.At the same time, the equipment meets the national requirements for energy conservation and environmental protection.

After sales:
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.
2.Training
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.
