installation to avoid damage of the machine and personal injuries.

STM

- PW series high temperature water heaters are used to heat up the 

mould and maintain temperature, although they can be used in other similar 
applications. High temperature water from the mould is returned to the 
cooling tank and cooled by either indirect cooling ( For high temperature 
models ) or direct cooling ( for standard models ). It is then pressurised by 
the high - pressure pump, sent to the heating tank and finally to the mould 
with a constant temperature. The OMRON temperature controller can 

 o

maintain an accuracy of 

1 C.
