RE: Melt temperatures in injection moulding & direct AIM

We do a fair amount of AIM type tooling. With ABS and Polypro parts we are
injecting at temperatures between 400 - 450F. Polypro works great with
AIM!

Subject: Melt temperatures in injection moulding & direct AIM

I have two questions, can anyone help me with them.....

1. What is the highest melt temperature that has been successfully used
successfully in direct AIM?

2. When ejecting polypropylene parts is there a recommended temperature
that the moulding should have cooled to before ejection or do moulders
find the earliest point to eject without compromising part quality?

Many thanks
