Vacuum pressure sintering furnace for cemented carbide research
Main application
For dewaxing of high-performance cemented carbide material(It can
realize vacuum dewaxing),It apply to research for lab and mass
production for factory of vacuum sintering ,partial pressure
sintering,gas pressure sintering
General description
This kind of vacuum pressure sintering furnace for cemented carbide
research, which is single room,horizontal type,recycle heating
furnace,it adopt graphite heating element of low voltage and large
current .All the technical process is automatic
controlled,monitored,chased,fault diagnosed which showed and
recorded by computer.
Design standard:JB4732-95,20-year service life,double doors
horizontal structure,6000 times.
Horizontal design for easy loading/unloading and easy maintenance.
Automatic control of the entire process
This kind of sinter-HIP furnace for cemented carbide production,it
includes control system,heating system,dewaxing system,vacuum
system,partial pressure sintering system,gas pressure sintering
system,rapid cooling system,Assist System ,Security System.
Furnace heating element, insulation and charging box are all in
cylindrical structure, compared with the traditional square
structure:Charging room is larger, size is more flexible, the
temperature and atmosphere more uniform.

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.
