500*500*1800 single-chamber with horizontal structure sinter-HIP
furnace
Main application
It can be used for high-performance carbide materials (positive
negative pressure dewaxing, forming agent for paraffin or PEG) and
vacuum sintering and low pressure argon gas static pressure
sintering sintering, high pressure and low pressure argon dynamic
pressure sintering, high temperature and high pressure conditions
of argon charged cooling/insulation/warming mature equipment as the
main function of batch production.Applicable to the field of
cemented carbide, ceramics and other products.
Total structure
1. The pressurized sintering furnace is single-chamber, horizontal
and periodic heating, heated by low-voltage and high-current
graphite heating elements, and has multiple heating units, each of
which separately controls the temperature.The whole process is
controlled by computer automation, monitoring, tracking, fault
self-diagnosis simulation display and record.
2. The pressurized sintering furnace includes control system,
heating system, degreasing system (positive and negative pressure
degreasing system), vacuum system, partial pressure sintering
system, pressurized sintering system, cooling water system, rapid
cooling system, auxiliary system and safety system.On the whole, it
meets the strict requirements of high performance cemented carbide
in the sintering process for the uniformity of furnace temperature
and atmosphere.The furnace structure design is advanced and
reasonable, which is convenient for operation and maintenance.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 also 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.
