Discover Castaldo rubber moulding products
Castaldo offers a full range of moulding rubber products designed for accurate, reliable jewellery mould-making. The silicone moulding putty creates fast, cold-cure moulds of wax, resin and ceramic models. Available in soft or firm grades, it cures in just 15 minutes, making it ideal for metal clay artists and jewellers needing quick, detailed impressions.
Castaldo liquid moulding rubber delivers bubble-free results with 0% shrinkage, perfect for 3D-printed resin masters and precision pieces. It is available in standard half-hour cure or fast-cure options that set in 60–90 minutes at room temperature.
Durable liquid mould frames provide secure housing for all RTV Castaldo rubbers and come in multiple sizes for different moulding setups. The non-toxic mould release spray ensures wax patterns are removed cleanly while extending mould life.
Why choose Castaldo for jewellery making?
Castaldo Econosil jewellery moulding rubber and the wider Castaldo silicone and natural rubber ranges are trusted for their:
- Excellent detail replication
- Reliable curing performance
- Strength and longevity
- Compatibility with wax, resin, metal clay and 3D-printed models
From producing master moulds to high-volume replicas, Castaldo jewellery moulding rubber supports consistent, professional results.
What type of Castaldo rubber should I use?
Use silicone moulding putty for quick, cold-cure moulds or when working with wax, resin or ceramic models. Choose liquid silicone rubber for 3D-printed or highly detailed masters requiring 0% shrinkage. For traditional mould-making, natural moulding rubber, soft for fine detail, firm for structural pieces, provides long-lasting, high-precision results.
