Graphite Ingot Mold for Gold & Silver Casting

1000g–9000g (1kg–9kg) Capacities Available

Professional-grade graphite ingot molds designed for clean, consistent casting of gold, silver, copper, aluminum, and other non-ferrous metals.

Whether you are pouring 1kg batches in a home furnace or producing larger bars in a workshop setting, these molds are built for durability, thermal performance, and smooth release.

Available Capacities

Choose from multiple cavity sizes ranging from:

• 1000g (1kg)
• 1100g
• 1200g
• 1400g
• 2000g (2kg)
• 5000g (5kg)
• 7500g (7.5kg)
• 9000g (9kg)

Each mold is precision-machined to produce clean, rectangular ingots suitable for refining, resale, or storage.

Select your capacity based on your furnace size and batch volume.

High-Purity Graphite Construction

Manufactured from dense, low-ash graphite (less than 0.1% ash content) to help preserve metal purity during casting.

• Rated for temperatures up to 1800°C (3272°F)
• Excellent thermal conductivity
• Resistant to cracking when properly preheated
• Designed for repeated pours

Low ash content reduces contamination risk in precious metal refining applications.

Optimized for Home & Small-Scale Refining

Most commonly used by:

• Home gold refiners
• Silver recovery operations
• Jewelry scrap refiners
• Small foundry workshops
• Laboratory metal analysis

The 1kg–3kg range is ideal for electric melting furnaces.
Larger capacities are suited for higher-volume operations.

Smooth Release Performance

Graphite’s natural self-lubricating properties allow for easier ingot removal with minimal sticking.

For best results:

• Always preheat mold before pouring
• Avoid rapid cooling
• Allow gradual temperature changes

Proper use significantly extends mold life.

Important Notes

• Designed for non-ferrous metals only
• Not intended for ferrous casting
• Always use proper safety equipment when handling molten metal

Built for Serious Refiners

This is not decorative graphite.
It is a functional casting mold built for repeated, high-temperature use in refining environments.

Choose the capacity that matches your melt volume and furnace capability.
