Applications & Finished Products
Our Metal Forming Solution is widely used for:
• Gold & Silver Sheets
• Jewelry Wires and Chains
• Bracelets & Bangles
• Metal Strips for Stamping
• Hollow and Solid Beads
Process of Making Gold Coins
Principle: Gold or silver is melted and cast into uniform sheets or plates using vertical continuous casting technology.
Supporting Equipment: Induction power supply, cooling system, crystallizer.
Advantages:
• Produces high-purity, defect-free gold sheets.
• Continuous production with stable thickness.
• Saves material and improves efficiency.
Principle: The cast gold sheet is rolled into thinner plates with precise thickness control.
Supporting Equipment: Annealing furnace (for softening metal before further rolling).
Advantages:
• Achieves uniform thickness with ±0.005 mm accuracy.
• Mirror-like surface finish.
• Prepares material for accurate coin blanking.
Principle: High-speed stamping press punches out round blanks from rolled gold sheets.
Supporting Equipment: Coin blank molds, trimming tools.
Advantages:
• Fast production of consistent coin blanks.
• Minimal material waste.
• Suitable for large-scale minting.
Principle: Coin blanks are pressed under high tonnage using engraved dies to imprint detailed designs, logos, or text.
Supporting Equipment: Custom coin dies, hydraulic system.
Advantages:
• Produces sharp and durable impressions.
• Adjustable pressure for different coin sizes and patterns.
• Ensures consistent weight and fine detail reproduction.
