4412 sinter-HIP furnace apply to high-performance cemented carbide
materials
Main application
For dewaxing of high-performance cemented carbide material(It can
realize vacuum dewaxing,H2 dewaxing,binder can be paraffin or
PEG),Vacuum sintering,Low pressure Argon dynamic partial pressure
sintering,High pressure Argon sintering,cooling,heat preservation
and heating up under high temperature high pressure status.
General structure
This kind of vacuum pressure sintering furnace for cemented carbide
r
search, which is single room,horizontal type,recycle heating
furnace,it adopt graphite heating element of low voltage and large
current .It has many heating zone,each heating zone are individual
controlled .All the technical process is automatic
controlled,monitored,chased,fault diagnosed which showed and
recorded by computer.
This Sinter-HIP furnace include control system,heating
system,dewaxing system(vacuum dewaxing and H2 dewaxing),vacuum
system,partial pressure sintering,pressure sintering system,cooling
water system,rapid cooling system,auxiliary system and safety
system etc.It’s graphite box built-in insulation structure,must
keep the best temperature and atmosphere uniformity when sinter
cemented carbide products.Main parts are all international advanced
products,can meet production needs stably and in the long term.At
the same time,it must meet energy conservation and environmental
requirements.

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.
