Digital Induction Stirring & Granulation Furnace

Delmer's Digital Induction Stirring & Granulation Furnace combines induction melting, digital induction pulsation stirring and controlled bottom-pour granulation in one industrial system for gold, silver, copper, brass and compatible alloys.

The digital induction pulsation function provides controlled electromagnetic stirring of molten metal. This promotes improved circulation and homogenisation of the molten bath, helping achieve more uniform mixing of metals and alloys before granulation. Stirring intensity and operating parameters can be controlled according to the selected configuration and process requirement.

Key Feature: Digital Induction Pulsation Stirring

Digital Induction Pulsation Stirring for Metal & Alloy Homogenisation

Unlike a furnace used only for heating and melting, the Delmer system incorporates digitally controlled induction pulsation to stir the molten bath. The electromagnetic stirring action helps distribute alloying elements and temperature more uniformly throughout the molten metal, supporting a more homogeneous melt before bottom pouring and granulation.

• Digital control of induction pulsation for stirring
• Improved circulation within the molten bath
• Supports homogenisation of metals and alloys
• Helps improve temperature uniformity within the melt
• Useful for gold, silver, copper, brass and alloy preparation
• Stirring can be applied before controlled bottom pouring and granulation

Available Models

Applications

The furnace is designed for melting, stirring, homogenisation and granulation applications involving gold, silver and copper, as well as brass and compatible metal alloys.

• Gold melting, alloy homogenisation and granulation
• Silver melting, alloy homogenisation and granulation
• Copper melting, alloy homogenisation and granulation
• Brass and compatible alloy preparation
• Precious-metal recycling and processing
• Gold and silver refinery operations

• Metal grain and granule production

How the Process Works

1. Charge loading: The selected metal or alloy charge is loaded into the crucible.
2. Induction melting: Induction heating brings the charge to the required molten condition.
3. Digital pulsation stirring: Controlled electromagnetic stirring circulates the molten bath to support temperature and alloy homogenisation.
4. Temperature control: The melt temperature is monitored using the configured temperature measurement system.
5. Bottom pouring: The homogenised molten metal is discharged through the controlled bottom-pour granulation system.
6. Cooling and collection: The metal solidifies into granules which are collected for further processing.

Isostatic Graphite Ingot Mould for Gold and Silver Casting

Delmer Group’s isostatic graphite ingot mould is a casting consumable for professional gold and silver melting, refining, bullion production and jewellery-manufacturing workflows. Molten metal is poured into the mould cavity and allowed to solidify into an ingot or bar shape.

Isostatic graphite is selected for its uniform structure, thermal stability and machinability. A clean, undamaged cavity can help produce repeatable ingot geometry and support metal release when the mould is correctly selected, prepared and maintained. Actual casting results depend on the metal, mould dimensions, heating and pouring procedure, equipment and operator practice.

Need a particular ingot weight or cavity size? Contact Delmer with your metal type, target ingot weight, required dimensions and casting method so the suitable mould configuration can be confirmed.

Key Features

• Isostatic graphite body: uniform material structure for a consistent machined cavity.
• Gold and silver casting: intended for compatible precious-metal ingot and bar casting applications.
• Thermal stability: graphite is suited to high-temperature casting when used within the correct process limits.
• Machined cavity: cavity geometry determines the resulting ingot shape and dimensions.
• Reusable tooling: service life depends on handling, thermal cycling, metal and process conditions, inspection and maintenance.
• Custom requirements: contact Delmer to confirm availability for specific dimensions and ingot-weight targets.

Applications

• Gold ingot and bar casting
• Silver ingot and bar casting
• Precious-metal refining and recycling workflows
• Bullion production and jewellery-manufacturing stock preparation
• Use as casting tooling with compatible melting and casting equipment

Material and Casting Process

Isostatic graphite is formed by applying pressure uniformly from different directions during manufacture. Its material properties can make it suitable for precision-machined casting tooling. Mould selection should account for target ingot weight, cavity volume and dimensions, metal density, pouring method and the capacity of the associated melting or casting equipment.

This mould is a passive tool. It does not provide induction heating, vacuum, or protective-atmosphere control. Where required, these functions must be provided by the associated equipment and process.

Technical Specifications

Important: Do not assume a standard ingot weight from the product image. Gold and silver have different densities; the same cavity volume will not produce the same mass for both metals. Confirm cavity dimensions, capacity, material grade and compatibility before purchase.

How to Choose the Correct Graphite Ingot Mould

1. Specify the metal: gold, silver or another proposed metal/alloy for compatibility review.
2. Specify the target ingot: provide target mass and external dimensions.
3. Check the equipment: confirm the melting furnace capacity and the casting method, such as gravity or tilt pouring.
4. Confirm the mould: obtain the cavity dimensions and material details before placing the order.

Handling and Maintenance

• Inspect the mould for cracks, chips or cavity damage before use.
• Keep the cavity clean and dry; avoid contamination from oil, moisture or debris.
• Handle carefully because graphite can be brittle and may chip if dropped or struck.
• Avoid abrupt temperature changes and follow the process and equipment supplier’s preparation, preheating and cooling instructions.
• Allow the mould and casting to cool according to the approved process before demoulding.
• Replace moulds showing damage or wear that could affect safe operation or casting quality.

Frequently Asked Questions

What is a graphite ingot mould used for?
A graphite ingot mould provides a cavity in which molten metal solidifies into an ingot or bar. This product is intended for gold and silver casting applications, subject to confirmation of size and compatibility.

Can this mould be used for both gold and silver?
The product is intended for gold and silver casting. Confirm the required cavity dimensions and process compatibility before ordering. Because the metals have different densities, the same cavity volume results in different ingot masses.

Does the mould provide vacuum or inert-gas protection?
No. The mould is a passive casting tool. Any vacuum, induction heating or protective atmosphere must be provided by compatible casting equipment.

Are dimensions and ingot capacity standard?
Specific cavity dimensions and capacity should be confirmed with Delmer. Provide the target metal, ingot weight and dimensions when requesting a quotation.

Can a custom mould be requested?
Contact Delmer with the required cavity geometry, ingot dimensions, target mass, metal and casting method. Custom availability must be confirmed.

Request Technical Information

Before ordering, ask Delmer to confirm mould dimensions, graphite grade, cavity capacity, compatibility with your process and availability. For a faster recommendation, include your metal type, required ingot mass, target dimensions and melting/casting equipment.

Contact Delmer Group for technical information →

Choose the Right Casting Equipment

This graphite ingot mould is a passive tool for compatible gravity or tilt-pour ingot casting; it is not the water-cooled die used in a continuous casting system. For suitable batch melting and pouring, explore Delmer static and tilting induction melting furnaces and Delmer gold and silver bar furnaces. If your production requires continuous rods, strips or profiles, compare the process with Delmer continuous casting systems; these systems use process-specific tooling, so do not assume this ingot mould is compatible. Confirm the target metal, ingot weight, cavity dimensions and casting method before purchase.
