Silicone Molds for Plaster and Plaster Impressions - Perfect Results Guaranteed

Discover why silicone molds are the ideal choice for plaster and plaster impressions . Our professional silicone collection offers the perfect properties for creating high-quality plaster reproductions, from fine artwork to industrial plaster parts.

Why Silicone is Perfect for Plaster

Excellent Release: Silicone has natural non-stick properties, allowing plaster casts to come out of the mold effortlessly without damage or cracking.

Flexibility for Undercuts: The flexible properties of silicone allow for the perfect molding of complex shapes with undercuts, something that is impossible with rigid molds.

Detail reproduction: Silicone captures even the smallest details, from fingerprints to textures, making your plaster casts a perfect reproduction of the original.

Durability: Our silicone molds can handle hundreds of plaster casts without loss of quality, making them perfect for both one-off projects and series production.

Ideal for Our Porcelain Plaster

Our silicone molds are specifically designed for use with our porcelain plaster —a high-quality plaster known for its fine texture and smooth finish. Combining our silicone molds with porcelain plaster produces exceptional results for:

  • Art objects and sculptures
  • Decorative ornaments
  • Architectural details
  • Prototypes and models
  • Restoration projects

Also Perfect for Acrylic One Applications

In addition to plaster, our silicone molds are also ideally suited for Acrylic One (A1) systems . The chemical resistance of our silicone makes them perfectly compatible with acrylic resins, allowing you to choose between:

  • A1 Acrylic Resin - For transparent and colored casts
  • A1 ATP Powder - For filled systems with increased strength
  • Acrylic Resin Color Paste - For creating colored objects
