Technical Specifications for Automated Hydraulic Production Lines for Commemorative Coins, Medals, and Badges

Key specifications for automated hydraulic production lines for commemorative coins, medals, and badges vary based on production capacity and product precision requirements. Currently, the core forming units in these lines typically utilize four-column hydraulic presses with tonnages ranging from 50 to over 1,000 tons. By integrating automated feeding systems, they achieve fully automated production—from raw blanks to finished products. The following technical specifications and parameters have been compiled by the Jianlong Hydraulic Technology team based on existing product data to assist with your procurement decisions.

1. Core Machine Parameters (Reference)

The following examples are based on automated hydraulic production lines actually manufactured by Jianlong for clients; equipment of different tonnages offers varying processing capabilities and application ranges.

Note: The parameters above are examples; actual specifications—such as daylight opening and bolster dimensions—can be customized to meet specific process requirements.

2. Key Technical Features

2.1 High Precision and Rigidity: The machine frame and moving bolster feature high precision and rigidity with strong resistance to lateral forces. This makes them ideal for pressing asymmetrical products or those with intricate details, ensuring mold coaxiality errors are kept to a minimum.

2.2 Advanced Drive and Control: Many production lines utilize imported servo motors and hydraulic control systems to ensure rapid response and high production efficiency. Operating stroke, pressing time, and pressure levels can all be adjusted according to process requirements.

2.3 Automated Integration: To boost efficiency, production lines are typically equipped with automated feeding systems (e.g., vibratory bowl feeders combined with robotic arms). These systems ensure precise blank positioning (tolerances within ±0.1mm) and coordinate with the main press to execute processes such as pressing and collection.

2.4 High-Reliability Components: Hydraulic cylinders are manufactured via integral forging and precision grinding, while the four columns are made of high-strength alloy steel with hard-chrome plating, ensuring stable, long-term operation under high-pressure conditions.

2.5 Comprehensive Safety Protection: Multiple safety measures—such as photoelectric safety sensors and protective guards—are standard features, ensuring compliance with modern industrial safety standards. 3. Workflow and Automation

The complete workflow for this production line typically includes: automatic blank feeding → mold closing → high-pressure coining/forming → pressure holding/setting → mold opening → finished product ejection and collection. The entire process enables automated, cyclical operation. For instance, compared to traditional equipment, a large-scale automated production line in the 800-ton class can boost production efficiency by over 30%.

4. Selection Recommendations and Considerations

4.1 Tonnage Selection: Equipment with a capacity of 100–300 tons is generally sufficient for standard commemorative coins and badges. However, for high-volume, high-efficiency production, or for products with larger diameters or higher relief profiles, large-scale equipment rated at 500 tons or higher should be considered.

4.2 Customization: Production lines are typically customized based on the client's specific products (dimensions, materials, and manufacturing processes). The parameters listed above are typical values; please contact us to discuss the actual technical solution in detail.

These parameters cover a wide range of factors. Are you currently evaluating a procurement plan for specific equipment, or do you need a technical solution matched to a particular product (such as large-format commemorative medallions or specific materials)? Let us know your specific requirements, and we can provide a detailed comparative analysis. Currently, Jianlong Hydraulic Technology offers customized hydraulic presses ranging from 10 to 5,000 tons (including supporting automated production lines, chillers, air compressors, etc.).
