plastic injection machine

Demolding my an address sign for the house, which I cast from aluminum using a simple investment casting technique. See my other video for the pour. The pattern is foam, which is vaporized by molten aluminum, which then fills the cavity. I design plastic housings for a living and so constantly think about the part as it exists in a mold. A lot of effort goes into designing parts that are manufacturable and then chosing gating and mold constructoins that work. Some of that experience has been proving useful in my DIY casting efforts, even though plastic injection tooling is a totally different world. If there’s interest, I’ll keep posting videos of my metal casting experiments.
