For jewellers vulcanizing smaller models, this compact aluminium frame is a practical alternative to standard sizes. It reduces rubber consumption and material cost per mould, making it an economical choice for producing single-cavity moulds for rings, pendants, and other compact jewellery pieces.
Key features
- Milled from a solid block of aluminium for durability and even heat transfer.
- Compact 3⅜" × 4⅜" outer dimensions with a 1⅜" thickness.
- Features a single, central cavity with rounded internal corners.
- Machined flat parallel faces ensure consistent pressure in the vulcanizer.
- Uses less mould rubber than standard frames for smaller jewellery models.
Who it's for
Ideal for UK bench jewellers, casting houses, and jewellery design studios who regularly produce rubber moulds for smaller-scale items. Also suitable for model makers requiring a robust frame for vulcanizing small, detailed parts.
Specifications
- Material: Aluminium
- Outer Dimensions: 3⅜" × 4⅜"

How this compares
| Aluminum Mould Frame, 1-3/8""... | Alternatives | |
|---|---|---|
| Material construction | Milled from a solid block of aluminium | Cast or fabricated aluminium, prone to warping |
| Cavity configuration | Single, central cavity with rounded internal corners | Basic single cavity, often with sharp internal corners |
| Heat transfer and pressure | Machined flat parallel faces for even heat and consistent pressure | Uneven faces leading to inconsistent pressure and heat distribution |
| Rubber consumption | Reduces rubber consumption for smaller models | Standard frames requiring more rubber for small items |
