Open nozzle is common when molding NOVADURAN. The nozzle of commercially-supplied injection machine
can be open nozzle or shut-off nozzle (Figure 1-1) but in any type, it is necessary to have a temperature control.
If drooling from the nozzle is concerned, use the shut-off nozzle. However, it might cause burn and sunspot
object by resin retention at the slide part, so be careful.
