Flow control in injection moulding machines
Variations in mould temperature can lead to sink marks, short
shots, cracks, and other defects. Keeping the mould as close as
possible to the optimum temperature is very important. Flow control
is the most important factor in controlling this variable. Because
plastic moulding machines generally operate on long cycles, maximum
daily production volume is based on machine capacity. If downtime
is a result of defective products or mechanical issues, production
cannot resume until the mould temperature is stabilized.
Restarting the moulding process while the temperature of the mould
is still unstable will produce products that are defective. It
generally takes about two hours of waiting time until production
can be resumed, resulting in huge losses. Due to this lengthy
recovery time, temperature related downtime can lead to production
schedules not being met. A single problem can be the difference
between a profit
or a loss. Reliable flow control can be used to avoid this risk.
