Silicone Moulding Rubber Castaldo VLT®– 2.3kg

Description

Speed and Precision for Modern Jewellery Manufacturing

Castaldo VLT® is a revolutionary silicone moulding rubber that significantly speeds up the jewellery production process. It enables fast and precise mould-making directly from CAD/CAM designs, 3D-printed prototypes, and traditional wax carvings. With a vulcanisation temperature as low as 71°C, it is particularly suited for working with delicate resin models, preventing deformation or melting during the moulding process.

This fast-curing rubber allows manufacturers to go from design to production in as little as 30 minutes, making it an essential material for jewellery workshops that demand efficiency and high precision.

Exceptional Wax Injection Results

Castaldo VLT® produces highly detailed wax injections with an extraordinarily smooth and shiny surface, reducing the need for extensive finishing. The rubber has a self-releasing property, eliminating the need for release sprays and ensuring a hassle-free casting process.

The rubber is also easy to pack and cut, making mould-making quicker and reducing the risk of errors. With an incredibly low shrinkage rate of just 0.1%, jewellers can achieve highly accurate reproductions of their original designs.

Versatile and Easy to Use

While designed primarily for CAD/CAM and rapid prototyping models, Castaldo VLT® also works exceptionally well with traditional wax carvings. Its soft and pliable consistency makes packing mould frames simple and requires no special tools. The resulting silicone rubber moulds are strong, tear-resistant, and capable of lasting for years.

Vulcanisation Time & Temperature Options

The rubber can be cured at different temperature settings depending on the required speed and model sensitivity:

• 88°C for 30 minutes
• 82°C for 45 minutes
• 76°C for 60 minutes
• 71°C for 90 minutes

This flexibility allows jewellers to choose the ideal balance between speed and model preservation, especially when working with delicate materials.

Storage Recommendations

Due to its low-temperature curing properties, Castaldo VLT® may self-vulcanise if stored in high temperatures. To prevent premature curing:

• Store in a cool, dry place (preferably in an air-conditioned room).
• Avoid exposure to high summer temperatures or warm climates.
• Do not store at temperatures below 0°C.
• If possible, store in a refrigerator to maintain shelf life.

Key Benefits:

• Vulcanises at just 71°C, preventing heat damage to delicate models.
• Enables rapid production, with moulds ready in as little as 30 minutes.
• Ideal for CAD/CAM and rapid prototyping models, as well as traditional wax carvings.
• Produces detailed wax injections with a smooth, shiny surface requiring minimal finishing.
• Self-releasing wax properties, eliminating the need for release spray.
• Extremely low shrinkage (0.1%), ensuring highly accurate reproductions.
• Easy to pack and cut, reducing production time and increasing efficiency.
• Long-lasting and tear-resistant, making it a durable choice for high-volume production.
