Why are silicones used for Mould Making?
Silicone moulding rubber has many applications across a wide range of industries using various casting mediums. Silicone is chosen for its fine reproduction of detail, versatility, ease of use and physical strength.
Applications include:
- Casting materials & applications
- Wax for candles and use in the lost wax process for bronze casting
- Polyurethane for mirror and picture frames, architectural mouldings
- Polyester resin for giftware, figurines, sculptures
- Plaster for covings and cornices, film studios, figurines, fireplaces
- Ceramics for earthenware pottery
- Low melt alloys for toys, models
- Glass for auto windscreens
- Stone filled resins for replication of works of art, fireplaces
