Technical Specifications for Small-Scale Gold Coin Stamping Presses

There is no single standard model for small-scale gold coin stamping presses; their technical specifications are generally categorized based on tonnage (pressing force), drive mechanism (mechanical or hydraulic), and the level of automation. For the production of small gold coins weighing 1–5 grams, a pressing force of 10–20 tons is typically required, while larger coins or those made from harder materials may necessitate 30–50 tons or more. The following information is provided by the team at Jianlong Hydraulic Technology—please feel free to reach out with any inquiries!

1. Core Technical Specifications

1. Nominal Pressure (Tonnage)

This is the most critical parameter for equipment selection. Small-scale presses cover a broad range:

1.1 Entry-level/Small gold coins: 10 tons, 12 tons, 15 tons, 20 tons.

1.2 General-purpose/Medium-sized commemorative coins: 30 tons, 40 tons, 60 tons, 80 tons, 100 tons.

2. Slide Stroke and Adjustment

2.1 Maximum Stroke: For small hydraulic presses, this is typically around 300mm–400mm.

2.2 Stroke Adjustment Range: Many mechanical or hydraulic presses offer an adjustable stroke—typically between 10mm and 200mm—to accommodate molds of varying thicknesses.

3. Table Dimensions

The table (bed) of a small-scale press must be large enough to accommodate the installation of molds:

3.1 Width × Depth: Common dimensions include 500×400mm, 550×450mm, 600×500mm, etc. Some four-column hydraulic presses may feature a table width of up to 750mm.

4. Motor Power and Power Supply

4.1 Power: Small-scale presses typically utilize motors ranging from 2.25kW to 7.5kW; higher-tonnage units (e.g., 100-ton class) may be equipped with 5.5kW or 7.5kW motors.

4.2 Voltage: Industrial-grade models typically operate on 380V three-phase power.

5. Machine Weight and Dimensions

5.1 Weight: Small-scale machines (10–20 ton capacity) are relatively lightweight, ranging from approximately 280 kg to 860 kg; 40-ton models weigh around 1,300 kg; while 100-ton models can range from 2 to 5.5 tons.

5.2 Dimensions: The height of small-scale machines generally falls between 1.45 meters and 2.8 meters, depending on the structural design (C-frame or four-column type).

6. Selection and Process Considerations

6.1 Drive Mechanism: Common options for small-scale machines include mechanical presses (high speed, suitable for simple, mass-produced coins) and hydraulic presses (stable pressure, ideal for intricate relief work or deep stamping). hydraulic presses typically feature adjustable pressure settings, making them better suited for applications like gold coin production, which require precise pressure control.

6.2 Level of Automation: For small workshops or custom production, manual or semi-automatic models are sufficient (manual operation can yield over 2,000 coins per day). If high output is required, fully automatic models can achieve a daily production capacity of 8,000 to 10,000 coins.

6.3 Die Compatibility: When purchasing, verify whether the machine supports double-sided stamping and allows for easy die changes to accommodate various coin shapes, such as round or non-round (oval, square) gold coins.

In summary, when making a purchase, you should finalize the technical specifications based on the diameter (typically 10–50 mm), thickness (1–5 mm), and material hardness of the gold coins you intend to produce.
