cdocastHydraulic Press For Coin &Bar Minting .Customized Design Available
CDOCAST hydraulic press for minting is designed for gold and silver coin minting, bullion bar logo stamping, medal forming and commemorative piece production. The machine applies stable, controllable hydraulic pressure to transfer sharp logos, lettering and relief patterns from precision dies onto gold, silver, copper and other metal blanks.
Available from 100 to 1000 tons, our hydraulic coining press machines include economical frame-type presses, precision four-column hydraulic presses and energy-saving servo motor models. Each press can be matched with minting dies, sub-die holders and ejection systems for individual machines or complete gold and silver minting lines.
The correct structure and tonnage depend on product size, metal, relief depth, die area, output and automation requirements.
A practical option for common gold and silver coin minting and small-to-medium bullion bar logo stamping. It balances pressure, footprint and investment for regular production.

A cost-effective press with good access around the die area. Suitable for medium-size coins, medals and precious-metal bars where flexible setup and a compact structure are important.
Watch the frame press →
Four guided columns provide balanced movement and uniform pressure distribution. Choose this structure when parallelism, repeatability and consistent relief depth are priorities.
Watch the four-column press →
A high-tonnage solution for large dies, deep-relief patterns and continuous precision production. Its servo hydraulic system provides controlled forming force with lower energy use and operating noise.
The press converts hydraulic pressure into a controlled forming force so the die transfers a clean design onto the precious-metal blank.
Place the annealed coin blank or bullion bar accurately in the lower die.
The movable table approaches quickly, then changes to a controlled pressing speed.
Preset pressure, stroke and dwell time form the logo, text, edge and relief details.
The ram returns and the product is removed manually or by a matched ejection system.
There is no single structure that is best for every minting application.
Selection note: do not choose tonnage only by product weight. Send us the product diameter or dimensions, material, relief depth, die size and expected output so the press and tooling can be matched correctly.
Four clear advantages over a conventional fixed-speed motor. For selection details, read our hydraulic press buyer guide.
The pump reduces output during pressure holding and standby instead of running continuously at full demand.
Fine control of pressure, speed, position and dwell helps reproduce sharp logos and consistent relief depth.
Less idle running lowers operating noise and hydraulic-oil heat for a better workshop environment.
Saved recipes and smooth pressure build-up improve repeat orders while reducing unnecessary impact on costly dies.
The press, die and blank preparation form one process. A matched die holder supports the dies, distributes force, assists ejection and helps contain fragments if a die fails. This protects the press table and improves tooling life.
CDOCAST can supply bar dies, coin dies and matched tooling according to your artwork, dimensions and production target.

Practical answers for selecting and operating a precious-metal minting press.
Select it according to the product material, diameter or dimensions, design area, relief depth, die size and required output. Product weight alone is not enough to calculate suitable press tonnage.
No. Punching uses fast impact and a short stroke for cutting or blanking, while minting requires stable, continuous and uniform pressure—often with a controlled dwell time—to transfer fine die details.
A servo hydraulic press offers more precise control of pressure, speed and position, with lower noise and better energy efficiency. It is valuable for high-repeatability products, including small precious-metal bars and precision coins.
A frame press is compact, accessible and cost-effective for general production. A four-column press provides more stable guidance and uniform pressure, making it preferable for larger dies or applications requiring better parallelism.
It is usually not recommended. An oversized press can be inefficient at very low operating pressure and may increase tooling risk. Dividing a very wide product range between suitably sized presses generally improves control and efficiency.
Bolster plates absorb localized wear and deformation, support the tooling and protect the main press surfaces. They help preserve machine accuracy and are easier to repair or replace than the main table.
A matched sub-die holder distributes force, supports the dies, may integrate an ejection system and helps contain fragments if a die breaks. It improves rigidity, operating safety and mold life.
For a standard production shift, the built-in cooling system is normally sufficient. A separate water chiller may be recommended for continuous high-frequency operation exceeding about 10 hours, depending on ambient temperature and cycle rate.
Only after technical verification. The holder must match the press shut height, available stroke, die dimensions and control system. An incompatible assembly can damage the tooling or press.
The light curtain creates an infrared safety field near the working area. If a hand or object interrupts the beam during a hazardous movement, the control system stops the press cycle.
Tell us the metal, product dimensions, weight, relief depth, die size and target output. CDOCAST will recommend the press structure, tonnage, tooling and production configuration.
