complex geometries.
®

4. Any shape, Any product!

5. Salient Features
•Most suitable for deep cavity double walled
products.
•Superior process control
•Highly productive
•Constructional Rigidity
•Our reliability is your efficiency
•Energy efficient machine
•Our user interface knows you better.
•IoT ready

•Custom design available

8. Software
Superior Process Control with features like:
•Stop & Roll
•Inner Air system
•Temperature Profile control
•Recipe
•Safety interlocks
•Production Log
•Maintenance Alarms
•And many more
®

9. Recipe
•Enter all the parameters that you
need for your moulds.
•You can save 100’s of recipes.
•Separate log-in for heads, supervisors
and operators so only authorized
person can change parameters
•Have the flexibility of changing many
mouldsby selecting parameters from
stored recipes

10. Advance Parameters
•Auto-Reversal which can be used to
achieve more uniformity
•Timer and reminders for multilayer
production
•Arm delay for localized heating
•Furnace temperature profile
•Stop & Roll feature

11. Stop & Roll
•Let’s arm hold your critical areas of
component near the blower at pre-
defined angles for pre-defined time
delays.
•Helpful for selective heating of areas
that otherwise receive less air due to
geometric constrains helping achieve
more even thickness.
•Helpful to selectively heat areas more
where you may functionally need
higher thickness.

12. Temperature profile
•Layer wise temperature control is
possible aiding to lower temperature
for the foam layer
•Initial temperature can be kept higher
until powder reaches desired
temperature. This helps reduce the
cycle time
•Last part of heating cycle can be done
at lower temperatures to reduce
cooling time

13. Inner Air system
•It can be used for air amplifier to heat
deep cavities.
•It can be used to create in-mould
pressure.
•Can be used to activate pneumatic
drop-box on mould.
•Can be used for internal cooling
•To create inert environment by
nitrogen purging in mould

14. Maintenance
•Warnings & alarms pop up to remind
the operator to do maintenance
activity.
•Guidance is available in form of help
file.
•Burner & Blower tests can be
conducted.
•All electrical components feedback
and status can be monitored.

15. Production Reports
•With HMI you can export excel
reports of production.
•Machine utilization is noted
•Which arm caused how much delay is
highlighted so you can re plan the
mouldson arm to get arm ready on
time to go into the furnace.

16. IoT Ready
•Monitor the Production and get auto-
generated production reports in any
part of the world at any time.
•For immediately responsive after
sales services we can instantly
remotely take control to
troubleshoot.

17. Safety features
•Safety both in terms of operator and
machine is taken care in HMI during
programming.
•The arm unbalance is detected by the
system and won’t run above allowable
unbalance.
•Furnace won’t move forward unless the
arm is truly aligned or the doors are
completely in open condition
•Video of backside of furnace is visible near
furnace movement command so operator
is aware if anyone is in the furnace path.

19. Sliprings
•Very reliable, dustproof.
•Compact
•Easy to maintain
•Comes with 3 extra rings to quickly change
connection without disintegrating the
sliprings (this helps avoid complete
breakdown and buys time till maintenance
can be done)
