Hydraulic Press For Coin &Bar Minting .Customized Design Available
CDOCAST specializes in manufacturing high-precision hydraulic minting presses designed for creating sharp, detailed designs on gold and silver bars and coins
At the heart of our machine is a powerful hydraulic system. The process begins when a hydraulic pump converts mechanical energy into hydraulic energy. This energy is then transmitted via specialized hydraulic oil to a hydraulic cylinder, which converts it back into controlled mechanical force. This force is applied with high precision to stamp your custom designs onto workpieces, ensuring every detail is captured perfectly.
① Economical Logo Stamping Machine: Ideal for clients who require a simple, cost-effective solution for pressing custom patterns onto gold bars. This model is compact, user-friendly, and perfect for applications where a basic, high-quality stamp is sufficient without the need for an automatic ejector.
② Advanced Hydraulic Coining Press: Necessary for minting high-relief coins and complex bars. This robust press is designed for demanding production environments and can be equipped with automatic features for enhanced efficiency and output quality.
③ Robust Structural Options: Our presses are available in two primary structures to suit your technical requirements:
④ Four-Pillar Hydraulic Press: Offers exceptional stability and alignment under high tonnage, ideal for the most critical minting applications.
⑤ Frame-Type Hydraulic Press: Provides superior rigidity and guiding accuracy, ensuring consistent performance and prolonged die life. Furthermore, they can be configured with the cylinder positioned above or below (C-frame style), providing flexibility for various production line setups.
⑥ Tailored to Your Minting Needs: Each of our hydraulic presses can be equipped with an automatic control panel for simple operation, allowing for easy adjustment of pressure and speed. The required press tonnage is determined by the material thickness, coin size, and design complexity of your pattern. As a complete solution provider, CDOCAST also offers professional custom logo and mold design services to bring your unique vision to life.

Q1: Your Hydraulic Presses range from 100 to 1000 Ton. How do I select the right one for my production?
A: Selecting the correct press tonnage is critical for quality and efficiency. We recommend the optimal model based on a thorough analysis of three key factors: the raw material of your product, the final product dimensions, and the intricacy of the design/pattern to be stamped. This ensures you get a press that delivers flawless results without under or over-investing.
Q2: In a Coin Minting Line, there is both a Hydraulic Punching and a Hydraulic Press Machine. Can one machine replace both?
A: Generally, we do not recommend combining these functions into a single machine. The primary reasons are:
*Different Dies & Process: Each process requires dedicated dies, and frequent die changes in production are impractical and inefficient.
*Different Technical Requirements:
The Hydraulic Punching Machine requires an extreme, instantaneous impact force with a very short stroke. It operates like a paper hole puncher, demanding “speed, precision, and power,” with high requirements for machine rigidity and the hydraulic system’s burst pressure.
The Hydraulic Stamping Machine requires stable, continuous, and uniform pressure, often with a pressure-holding function. It works like a precision printing press, needing even pressure across the entire mold to ensure sharp, consistent, and deep-struck details. It demands extremely high precision and stability in pressure control.
Q3: What is the difference between a Servo Motor-driven Hydraulic Press and a Standard Motor-driven one?
A: The servo motor drive offers significant advantages:
*Energy Efficiency & Noise: Servo-driven presses are remarkably quieter and more energy-efficient, creating a better working environment and reducing operating costs.
*Precision Control: The servo motor allows for infinite and highly precise pressure adjustments, whereas standard motors have limited control. For products like 1g-200g gold bars, where exquisite detail is critical, we strongly recommend a servo-driven press for its superior pressure precision.
Q4: What is the difference between a Frame Type (C-Type) and a Four-Column Hydraulic Press?
A: Both have their merits for specific applications:
*Four-Column Press: Offers superior structural stability and excellent pressure distribution, making it ideal for high-precision tasks. It typically comes at a higher price point.
*Frame Press (C-Type): A robust and cost-effective solution for many applications.
We will recommend the most suitable structure based on your specific product and technical process requirements.
Q5: If I produce gold bars from 1g to 500g, can one COINING PRESS MACHINE handle all weights?
A: We do not recommend using a single press for such a wide weight range. Here’s why:
*Initial Pressure: Every press has a minimum initial pressure (e.g., 50 Ton for a 300T press). A 1g bar may only require 10 Ton, meaning the machine’s minimum is still excessive, leading to premature mold wear and damage over time.
*Energy Efficiency: Using a large-capacity press for small products is highly inefficient. The energy consumption (electricity/hydraulic oil) is significantly higher than using a appropriately sized machine, leading to substantial long-term operational waste.
Q6: Why do your minting line presses come with upper and lower bolster plates?
A: The bolster plates are a critical protective feature. During long-term operation, the press’s bed and slide can develop minor deformations. These installed bolster plates absorb this wear, protecting the main machine’s critical surfaces from damage and ensuring long-term accuracy.
Q7: Why is a sub-Die holder (die set) necessary for the press?
A: The sub-Die holder is essential for safety, efficiency, and quality:
*Pressure Distribution: It helps distribute pressure evenly, which is crucial when using small molds for lightweight bars on a larger press.
*Integrated Ejection System: Our bolster plates and sub-mold holders are designed together with an **automatic ejection system**, making production safer and more efficient.
*Safety & Durability: In case of operator error causing excessive pressure and mold breakage, the sub-mold holder contains the fractured pieces, preventing injury and equipment damage. This also reduces downtime. Furthermore, it supports the mold structure, enhancing rigidity and prolonging the overall mold life.
Q8: Is a water chiller necessary for the hydraulic press?
A: A water chiller is only necessary if your operation involves continuous, uninterrupted work cycles exceeding 10 hours. For standard shift operations, the built-in cooling system is sufficient.
Q9: Can we purchase your automatic ejection sub-mold holder for our existing press?
A: This is generally not feasible. The installation height and stroke of the ejection system must be precisely matched to your press’s shut-off height. A mismatch will prevent the automatic ejection from functioning and could lead to severe equipment damage or safety hazards.
Q10: Why are light curtains important on a hydraulic press?
A: Light curtains are a vital operator safety feature. They create an invisible infrared barrier around the pressing area. If a worker’s hand breaks this light beam during operation, the press will immediately stop, preventing potential accidents and ensuring a safe working environment.
