Hot Runner System Control
(Our Customer)
Soft start
temperature control system for precise temperature control of hot
runner system (HRS) used in plastic injection moulds. It enhances the
life of costly heaters and reduces the machine down time caused due to
premature failure of heaters.
The system comes in single or multichannel with capacity ranging from
1KW onwards. It comes in an elegantly fabricated powder coated panel
with castor wheels and heavy-duty connector on the side for easy
connection.
The cartridge heaters used in the HRS being hygroscopic by nature
absorbs moisture, which can create short circuit and destroy the heater
when full supply voltage is applied initially. This care is taken by
our system by applying a reduced voltage initially till such a time in
which the moisture is baked out and no dampness remains.
There after the phase angle fired thyristor circuit takes over the
temperature control part. There is no ON-OFF cycle of heaters causing
thermal shock and the controller ensures that just enough power is
supplied to the heaters to maintain the set point. It also has
provision for open loop control of heaters in the event of thermocouple
failure.
