Core Features of Coin and Medal Imprinting Hydraulic Presses

Unlike traditional hydraulic presses used for forging, coin and medal imprinting hydraulic presses belong to the category of precision pressing, with high precision, high stability, and perfect surface treatment as their core requirements. Below are its six core features, shared by Jianlong Hydraulic Technology.

1. Extremely High Precision and Control Capabilities

1.1 Positional Accuracy: Employing precision displacement sensors and a servo control system, the repeatability of the slider can reach ±0.01 mm or even higher. This ensures that the imprinting depth of each coin and medal is completely consistent, eliminating inconsistencies.

1.2 Pressure Control: Achieving extremely precise pressure control, typically within ±1%. This is crucial for protecting expensive molds and ensuring perfect pattern formation. Too little pressure results in a blurry pattern; too much pressure can damage the mold and cause excessive metal flow, producing flash.

2. Unparalleled Stability and Rigidity

2.1 Machine Structure: Utilizing an integral casting or prestressed frame structure, it boasts extremely high rigidity. The goal is to ensure minimal deformation of the machine body when subjected to impact loads of hundreds or even thousands of tons. This is fundamental to guaranteeing consistent thickness and uniform patterns on the embossed products.

2.2 Fatigue Resistance: Designed for long-term, high-frequency continuous embossing operations, all core components possess extremely high fatigue strength, ensuring the equipment maintains its initial accuracy over years or even decades of use.

3. Advanced Process Control and Flexible Production

3.1 Multi-Stage Embossing Process: Programmable control allows for multi-stage embossing processes such as "light pressure - venting - heavy pressure - holding pressure." For example, when embossing commemorative badges with colored paint, a light pressure is applied first to initially position the paint, then the pressure is slowly increased, effectively preventing the paint from being squeezed out.

3.2 Multiple Control Modes: Seamless switching between "constant pressure control" (pressing to a set pressure) and "constant stroke control" (pressing to a set depth) is possible to adapt to the needs of different materials and designs.

3.3 Recipe Storage Function: The human-machine interface allows storage of imprinting parameters (pressure, speed, stroke, holding time, etc.) for hundreds of products. When changing products, simply recall the corresponding recipe, significantly reducing debugging time and human error.

4. Excellent Operability, Safety, and User-Friendly Design

4.1 Human-Machine Interaction: Equipped with a large-size color touchscreen, it displays pressure, stroke, number of cycles, fault information, etc. in real time, making operation intuitive and simple.

4.2 Comprehensive Safety Protection: Standard features include photoelectric safety light curtains, two-hand operation buttons, and fall arrestor safety bolts, maximizing the protection of operator safety and mold assets.

4.3 Convenient Mold Installation: The worktable often features T-slots, hydraulic clamping, or quick mold change mechanisms, simplifying the mold change process and improving production efficiency.

5. Low Noise, Low Energy Consumption, and Environmental Friendliness

5.1 Servo Drive Technology: This is a hallmark of current high-end imprinting machines. Servo motors operate only when needed, reducing energy consumption by 20%-60% compared to the continuous operation of traditional asynchronous motors. They also reduce oil heating and lower cooling costs.

5.2 Low-Noise Design: The precise hydraulic system design and excellent mechanical structure ensure smooth and quiet operation, with noise levels significantly lower than ordinary hydraulic presses, improving the working environment.

6. High Reliability and Long Lifespan

6.1 Core Components: Key components such as hydraulic pumps, valves, and seals typically use internationally renowned brands, guaranteeing the equipment's reliability and durability from the outset.

6.2 Exquisite Manufacturing Process: From casting and heat treatment to precision machining, every process is rigorously controlled to ensure the overall quality and lifespan of the equipment.

In summary, behind every perfect commemorative coin or medal lies a coin and medal stamping hydraulic press that integrates high-precision mechanics, intelligent electronic control, and advanced hydraulic technology. Its core characteristics are not only "powerful" but also "precise, stable, intelligent, and safe," perfectly embodying the concept of precision manufacturing.
