Today 'SANTEC' is respected all over the world as
a manufacturer & exporter of the most modern & state of the art
hydraulic presses by adopting an uncompromising quality attitude &
providing outstanding services world wide
Transfer
Moulding Presses for Rubber Parts.
Transfer Moulding Presses for DMC / Urea
Transfer Moulding Presses for Switch Gears
These special transfer moulding presses are manufactured by 'SANTEC' to
suit rubber parts & DMC/ urea or switch gears or electrical parts
manufacturing industries. These presses have all latest facilities including
touch type panel screen, sliding & ejector arrangement & used to
produce, engine mounting bellows, electrical switch gears, DMC & urea
parts dead end & polymer insulators.
In transfer moulding operation, the rubber flows from a separate reservoir
through flow channel, called a sprue, into mould. By using transfer moulding
presses produced by ‘Santec’ there are three advantages over
compression moulding presses.
» As the mould is closed before the rubber charge is forced
into it, closer dimensional control is achievable.
» In the transfer process, fresh rubber surface are produced
and this allows development of a strong rubber - metal bond with any insert
in the mould
» Unit production costs are lower due to shorter cure times as
a result of heating the rubber due to flow through sprue, runner and gates &
shorter downtime between runs, as only one charge blank is necessary, even
if a multi cavity mould is used.
This machine is accepted by top industries in India & other industries
in abroad because of its unique operating principle.
The clamping / closing of moulds is done by hydraulic cylinder
mounted in reverse direction on the fixed platen of the machine hence giving
downward & upward movement to the 4-pillars in place of platens. After
clamping of moulds by main clamping cylinder, the main injection cylinder
mounted at the top of the pillars, Transfers the preheated rubber inside of
the moulds with the help of runner & gates provided in the specially
designed moulds. Side core pullars are also provided in the presses to mount
middle part of mold. The transfer molding presses gives following advantages
:

Clamping capacity : 10 tons to 500 tons
Transfer cylinder capacity : 4 tons to 200 tons
Platen sizes : 8 sq. inch to 48 sq. inch
Heating : electrical
Operation: Both PLC with display controlled & relay / contactor based.
These special kind machine employ two- stage material supply. It
expels bubble out of the raw material in the highly effective way &
there is on waste material left in the injection system. These machine are
suitable for polygin, polyhedron & other complicated products especially
used in sports, medial automobile & electrical applications. These are
also used for various rubber components silicone rubber parts etc.
'Santec' is pleased to announce a state of the art Rubber Injection Molding
Machine fully equipped with all latest features.
The Important Features of this Machine are as follows :
» Special Screw mechanism preventing rubber strip rupture
during feeding.
» Acurate Temp. Control at all areas before Injection.
» Precise shot control.
» Material flow with low restrictions.
» Cleaning & maintenance of all parts very easy.
» Three stage closing of mould hence less working
height & fast closing
» User-Friendly Process Control System with the help of Touch
Panel Screen & PLC from Allen-Bradley make.
» Injection system is based on "FIFO" system.
» Closed loop speed control of three Injection steps &
exact positioning due to use of rotary encoders.
» Accurate Temp. regulation by PLC.
» Variable pump with proportional pressure & flow control.
