I am planning to injection mould small shots (5g) from polypropylene
using ACES moulds at ~14MPa (2000 psi). If I were using conventional
steel moulds I would be able to get away with a gate size as small as
0.5mm in diameter. Does anyone know of any limitations on gate/sprue
diameter when using ACES moulds as many pictures that I have seen
seem to have very wide gates.

Thanks
Neil Hopkinson
