vacuum debinding sintering integrated furnace with 3 heating zone
for temperature control independently
Design standard
The vacuum debinding sintering integrated furnace is a single
chamber double door horizontal and periodic heating structure.The
design is easy to load and unload and maintain, and the whole
process is controlled automatically.Realize full load continuous
operation, 300 furnace times/year or 300 working days/year.Graphite
element resistance heating (low voltage, large current);With a
plurality of heating units, each unit is independently controlled
temperature;Automatic control function, safety interlock function,
the whole process by computer automatic control, monitoring,
tracking, fault self-diagnosis simulation display and record.PLC,
industrial computer (PC) control to realize the whole process of a
key start, real-time dynamic monitoring, computer to temperature,
pressure, vacuum degree and other parameters, safe and reliable
alarm interlock.
Main requirements of equipment
Mainly used for carbide, ceramic materials, wear-resistant
materials, high temperature alloy AR, vacuum sintering, partial
pressure sintering (static, dynamic), vacuum cooling, rapid cooling
and other processes.It meets the strict requirements of furnace
temperature uniformity and atmosphere uniformity in the sintering
process. The furnace structure design is advanced and reasonable,
which is easy to use, operate and maintain.The main supporting
components (control components, sensors, graphite heating element,
thermocouple, main control valve, vacuum pump, etc.) have the
current international advanced level, can adapt to the long-term,
stable, reliable mass production requirements.At the same time, the
equipment meets the national requirements of energy saving 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.
