A Grand Rapids shop that makes silicone molds and pressure-cast polyurethane kits for sculptors, garage-kit labels, prop studios, museums, and short-run industrial projects.

Why it surfaced

Castvein explains the shop-floor realities most casting pages skip: mold pull counts, parting lines, trapped air, venting, fettling, and the cost of a late art change. Its promise is unusually concrete—send the master, not the deadline—and the site says it has worked with 480 sculptors and labels since 2011.

August 16’s newborn domains include a 240-material perfume organ, a repeatedly saved JPEG cat, a ski tracker designed by a 15-year-old, and a searchable page claiming to contain 148,303 prescription records.

This is one of 1,000 discoveries in the 2026-08-16 Domain Arrivals issue.
