Gold & Silver Coin Minting Equipment – Complete Production Lines
DelmerGroup provides complete coin production lines covering every stage of the minting process—from raw metal melting to finished, packaged coins.
Coin Production Workflow
Our integrated minting systems include:
- Induction Melting & Refining Furnaces : High-efficiency induction furnaces with inert gas or vacuum protection, designed for gold 999.9 and silver 999.9 purity.
- Vacuum & Continuous Casting Machines : Precision casting systems for coin blanks with minimal porosity and excellent metallurgical structure.
- Rolling Mills & Strip Processing : 2-high and 4-high rolling mills delivering thickness tolerances up to ±0.01 mm for consistent blank weights.
- Annealing Furnaces : Controlled-atmosphere annealing improves ductility and strike quality.
- Blanking & Piercing Presses : High-speed hydraulic and mechanical presses (50–1200 kN) for accurate blank production.
- Coining & Upsetting Presses : Heavy-duty coining presses up to 2,500 tons, suitable for bullion coins, proof coins, and high-relief commemorative.
- Edge Marking & Security Features : Reeding, edge lettering, micro-engraving, and laser marking for anti-counterfeiting.
- Polishing, Finishing & Packaging : Automated polishing, inspection, counting, and tamper-evident packaging systems.
Bullion Bar & Continuous Casting Production Lines
DelmerGroup designs bar and caster production lines for investment bars, minted bars, ingots, and industrial precious-metal applications.
Bar & Caster Line Equipment
- Induction Melting Furnaces (Crucible & Channel Type) : Capacities from 10 kg/hr to 2,000 kg/hr, optimized for low oxidation and high yield.
- Continuous Casting Machines (CCM) : Vertical or horizontal continuous casting for gold and silver bars, with adjustable speeds and modular mold systems.
- Ingot & Bar Mold Systems : Standard and custom molds for 100 g to 12.5 kg bars. Cutting,
- Rolling & Surface Finishing : Precision cutting, flattening, brushing, ultrasonic cleaning, and chemical passivation.
- Inline Quality Control : XRF analysis, optical inspection, and automatic weighing for real-time verification.
Quality Control, Compliance & Traceability
All DelmerGroup systems are designed to meet international bullion and refinery standards, including:
- Inline XRF spectrometers for alloy verification
- Automated weight checking with ±0.01 g accuracy
- Vision systems for surface and strike inspection
- Full batch, lot, and serial number traceability
- Environmental controls for fumes, waste, and coolant recovery
This ensures smooth compliance with national mint regulations, refinery audits, and global bullion market requirements.
