I am planning on doing some parts in molded EPS (expandable polystyrene). I will be doing the aluminum mold and also I am planning on doing a small molding machine for my parts. I will use these parts for Lost Foam Castings, but if this works, I want to find some costumers for packaging products.
If anyone can give me some pointers, it will be appreciated.

This process usually takes quite a bit of equipment. Between the press, feeders, steam generation etc.

Here is an introduction to the basic process. It first goes through how the beads are made, then explains their use in molding.

The dies do need steam vents based on a given cavity volume. Many have water cooling jackets to reduce the cycle times too.
