4.3 Nozzle requirements<br />
The nozzle goes approximately 37 mm into the mould base before it touches the mirror plate (picture 4.1). This means that<br />
the nozzle should pass the machine plate for at least 40 mm (e.g. 45 mm). The hole in the mould base is Ø42 mm<br />
(picture 4.2) so that the maximum diameter of the nozzle should be less than Ø42 mm (e.g. Ø40 mm). The radius at the<br />
back of the mirror plate is R 35 mm. The nozzle radius however, should be smaller e.g. 30-32 mm (picture 4.1). Based<br />
on our experience we advise to use a nozzle with a hole diameter of approximately 2/3x sprue diameter. As the sprue<br />
diameter is 6 mm (standard), we advise a nozzle hole diameter of 4 mm.<br />

4.4 Cooling medium<br />
Water with a rust preventing additive can be used as cooling medium. Alternatively following oil-types are recommended:<br />
ARAL<br />
: Farulin U<br />
BP<br />
: BP Transcal LT<br />
ESSO<br />
: Essothermalöl T<br />
MOBIL : Mobiltherm 603<br />
SHELL : Thermia Oil B<br />
HOUGHTON : Transtherm 496<br />
These are high-viscous mineral oils on paraffin base without additives.<br />
