4. Sprue (manufacturing) - Wikipedia

   en.wikipedia.org/wiki/Sprue_(manufacturing)

   In injection molding, sprue refers to the passage through which a liquid material (such as polystyrene or polyvinyl chloride) flows into a die, where the material solidifies to form parts. Sprue also refers to the material that solidifies in these passages, forming a framework that attaches the parts in a roughly planar arrangement.

5. Full-mold casting - Wikipedia

   en.wikipedia.org/wiki/Full-mold_casting

   If the volume is large, then the pattern can be mass-produced by a process similar to injection molding. Pre-expanded beads of polystyrene are injected into a preheated aluminum mold at low pressure. Steam is then applied to the polystyrene which causes it to expand more to fill the die. The final pattern is approximately 97.5% air and 2.5% ...
