Silicone rubber
To achieve high-quality castings, it is essential to use the right rubber.
The choice of the appropriate silicone rubber is essential for high-quality spin casting. The characteristics of the model to be reproduced determine the selection of the most suitable compound. For example:
- Undercuts: require soft, flexible rubbers to facilitate removal of the part from the mould.
- Large dimensions: they need rubbers with good thermal resistance to withstand the high temperatures during casting.
With the increase in quality standards imposed by the market, it was necessary to develop new rubbers for special applications. CABE offers a wide range of silicone compounds to choose from, ensuring that customers can find the product best suited to their needs and guaranteeing the use of first-class materials.
Among Spin Casting Materials, Silicone Rubber Compounds stand out as the most critical factor in ensuring precise and consistent results. Our Flexible and Durable Silicone Rubber is designed to meet the highest demands of quality and reliability.
