Sand Casting Flask — 2-Part Aluminium Mould Rings, 100 × 100 mm, Delft Clay & Petrobond

Perfectly align your cope and drag for crisp detail in sand casting with this 100mm aluminium mould ring set.

What it does

This two-part aluminium flask facilitates precise sand casting of intricate jewellery components. Its machined inner and outer lips ensure a secure, repeatable fit between the cope and drag halves, crucial for preventing mould shift during packing and pouring. The lightweight aluminium construction offers improved bench handling compared to heavier cast iron alternatives, making the process more manageable for detailed work.

How to use it

• Pack your sand firmly into both halves.
• Press your pattern into the sand.
• Join the halves and pour molten metal.

Who it's for

Ideal for UK bench jewellers, silversmiths, and metal casters creating rings, pendants, and small components. This mould replaces the need for more complex or expensive casting methods for one-off or small production runs, pairing perfectly with Delft Clay or Petrobond casting sands.
