The little machine to the left is a hot oil pump, it pips in hot oil and goes into the runner of the tooling to heat the mold evenly.
The is ABS raw material, the black dots and pigments that gives the plastic the color.

The S shape is the runner, where the oil would travel and heat the block evenly.
