Durable Plasters for Mold Making & Repeated Use
Build strong molds with the working time, heat resistance, and stability needed for dependable results.
Plaster is a reliable choice for mold making because it offers strength, detail reproduction, and dependable usability across many casting applications. Products like Ultracal 30 are especially well-suited for durable molds that need longer working time, added heat resistance, and consistent performance through repeated use.

Casting Plasters That Support Detail & Production Efficiency
Choose materials that deliver strength, moisture control, and reliable performance for cast parts and production pieces.
Different casting plasters offer different benefits depending on the process and end use. Hydrocal is often chosen for strong, detailed casts with moisture-wicking properties, while Hydrostone is a better fit for very strong, fast-setting production pieces that require clean results, dimensional stability, and efficient turnaround.
