Create Detailed Castings with Sand Casting Clay


Sand Casting Clay is an advanced, reusable moulding material that enables jewellers & metalworkers to create highly detailed & precise castings with ease. Suitable for gold, silver, copper-based alloys, pewter & other metals, it captures intricate designs with exceptional clarity while minimising the need for extensive finishing.


Its oil-bonded formulation provides excellent shape retention, dimensional accuracy & a superior surface finish. Patterns can be created from a variety of materials, including metal, wood, wax, epoxy & plastic, making it a versatile solution for custom jewellery, prototypes & small production runs.


The casting process is straightforward: a design is pressed into compacted clay within a specialised mould frame, channels are created for metal flow, & molten metal is poured into the mould to produce the final casting. Once complete, the clay can be reused multiple times, offering both cost savings & sustainability benefits.


When using Sand Casting Clay, the right equipment makes all the difference. Aluminium casting rings create crisp, detailed impressions, while the Cast Iron Jig keeps mould halves securely aligned for accurate, repeatable castings. The right tools mean better detail, less finishing, & consistently high-quality results.


Combining precision, efficiency & affordability, Sand Casting Clay is an ideal casting solution for workshops, artisans & hobbyists looking to achieve professional-quality results.
