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
