I need to make a lot of small silicone cylinders (30-40 mm long and 0.8-10 mm thick) with a minor detail at the end. What would be the best way to do it? I was thinking with molding but don't know which material to use for the mold. Ideally, it would be one which wouldn't require coating with lubricants prior to pouring silicone in the mold. I have a feeling this would significantly extend the production time at given quantities so I wish to avoid such step (also additional cost).

Any help would be greatly appreciated.
