cdocastBuy the Most advanced Hydraulic Logo Stamping Machine For Types Of Metals Bar
CDOCAST compact four-column hydraulic stamping press is designed for gold bar logo stamping, silver bar hallmarking, platinum ingot marking, serial number stamping and custom bullion brand embossing. It is suitable for mints, bullion bar factories, precious metal refineries and jewelry production workshops that need stable pressure and repeatable stamping quality.
For precious metal bar logo stamping, pressure tonnage is only one part of the decision. Buyers should also check frame rigidity, die positioning, working table size, stroke control, pressure repeatability and whether the machine can match custom logo dies for different gold, silver or platinum bar sizes.
Both models can be used for bullion bar logo stamping. The difference is mainly in machine structure, operating comfort, pressure stability and how often the customer needs to change dies for different gold and silver bar sizes.
| Item | Economic 100 Ton Stamping Press | Advanced Four-Column Hydraulic Press |
|---|---|---|
| Suitable use | Logo stamping, simple hallmarking and small-batch bullion bar marking. | Higher frequency stamping, cleaner alignment and more stable production. |
| Recommended buyer | Small gold shop, jewelry workshop or starter bullion bar production line. | Minting factory, bullion brand, precious metal refinery or professional bar producer. |
| Die positioning | Basic die positioning depends more on operator adjustment. | More stable frame and better support for customized positioning die sets. |
| Long-term production | Good for lower budget and moderate production volume. | Better for repeated stamping, consistent depth and long-term production use. |
A good bullion bar stamping result depends on both the hydraulic press and the stamping die. If the pressure is too low, the logo depth may be shallow. If the pressure is too high, the bar surface may deform and the die life can be reduced. For 1 oz, 100 g, 1 kg and larger bullion bars, the press model and die structure should be selected according to the bar size and required logo depth.
This model is suitable for customers who need a compact and cost-effective gold bar logo stamping machine. It can be used for silver bar hallmarking, simple bullion brand marking and small-batch precious metal stamping work.
The advanced model is designed for customers who need better machine rigidity, more stable pressure and cleaner stamping results. It is more suitable for professional bullion brands, refineries and minting factories that produce gold bars, silver bars and platinum bars regularly.
For gold bar logo stamping and silver bar hallmarking, the press provides the force, but the die decides the final detail. CDOCAST can design custom logo dies according to bar size, logo drawing, required depth and production volume. This helps reduce misalignment, uneven pressure marks and repeated die adjustment.
Send us your bar size, material, logo drawing and expected production volume. CDOCAST can help recommend the suitable 100 ton hydraulic stamping press and custom logo die solution.

Purpose-Built for Gold: Designed specifically for stamping characters and logos onto gold bars, ensuring clean and permanent marks.
Simple & Space-Saving: Features a simple structure and compact design, making it an easy-to-operate and space-efficient solution for any workshop.
Affordable Power: A highly cost-effective press that delivers immense value, generating tens of tons of pressure for high-quality results.
Ideal for Small Batch Production: Perfectly suited for small studios and factories looking for a reliable, low-maintenance stamping solution.
Streamlined Operation: The process is simplified and typically requires no additional pad formwork, getting you from setup to production in no time.
The stamping capacity depends primarily on the surface area (cross-section) and the thickness of the metal bar. In standard production, this model is fully capable of hallmarking casting bars up to 12.5kg (400 oz standard gold delivery bars) and smaller.
Easy Operation: A pressure control valve is located on the front of the machine, allowing you to flexibly adjust the force based on the bar size and the required depth of the stamp.
Real-time Monitoring: A pressure gauge on the right side allows operators to monitor the exact tonnage during the process, ensuring consistent stamping quality across every batch.
Yes, we offer complete custom tooling solutions.
Precision Alignment: We customize branding dies (stamping dies) based on your specific casting bar dimensions.
Integrated Die Sets: Our dies feature an integrated frame design with built-in positioning. Operators simply place the bar into the fixture for perfect alignment, and the bar can be removed smoothly after pressing, significantly increasing production efficiency.
We do not recommend this specific model for high-relief “minted” products (Minting Bars & Coins) for the following reasons:
Pressure Precision: Minting requires extreme precision for intricate relief; this stamping machine is optimized for hallmarking and logo identification.
Action Logic: Minting requires a “Fast Down — Slow Pressing — Slow Return” cycle to ensure full metal flow into fine details.
Speed vs. Aesthetics: This machine is designed with a “FastUp/Fast Down” logic to maximize stamping speed. While excellent for logos, it may not meet the aesthetic requirements of proof-like minted coins.
For high-quality coin production, please inquire about our Hydraulic Minting Press series
This machine is specifically engineered for precious metals, including Gold, Silver, Platinum, and Palladium bars of varying hardness.
Absolutely. By using interchangeable die inserts, you can simultaneously stamp your brand logo, weight (e.g., 1kg), purity (e.g., 999.9), and unique serial numbers
Our die features a “Quick-Change Tooling” design. No complex tools are required; a single operator can complete a die change in under 30 seconds, making it ideal for small-batch production of various bar sizes.
The dies are made from high-hardness alloy steel and undergo specialized heat treatment. Under normal operating conditions, a single set of dies can perform tens of thousands of stampings while maintaining sharp edges.
The hydraulic system is optimized to operate at under 75 decibels. Its compact footprint 110 *85 *135cm makes it perfect for small-to-medium factories or urban jewelry workshops.
We have implemented a four-tier safety protection system to ensure operator security:
Light Curtains: High-sensitivity infrared sensors stop the machine instantly if a foreign object enters the stamping zone.
Dual Start Logic: In semi-automatic mode, the operator must press two buttons simultaneously with both hands to prevent injury.
Flexible Controls: Choose between manual or semi-automatic modes, with the option for dual-button or foot-pedal control.
Emergency Stop: A prominent red E-Stop button provides millisecond-level power cutoff in emergencies.
The machine uses an energy-efficient 4KW motor, which saves approximately 20% more energy compared to traditional hydraulic presses. We offer custom configurations for both single-phase and three-phase power.
Warranty: CDOCAST provides a 2-year quality guarantee, including free replacement of non-wear parts.
Setup: No complex installation is required. The machine is fully calibrated before shipping; you only need to connect the power and add anti-wear hydraulic oil to begin. We provide detailed operation videos and manuals
No complex installation is required. The machine is fully commissioned and tested before leaving the factory; you only need to connect the power supply and add anti-wear hydraulic oil to begin operations. We provide comprehensive instructional videos and operation manuals to guide you.
The four-column design is the preferred choice for stamping gold and silver bars due to its superior stability, ensuring the die maintains a perfectly vertical press without deviation. To maintain high-precision performance over time, we recommend the following maintenance routine:
Guide Pillar Lubrication: Regularly apply lubricant to the four chrome-plated guide pillars to minimize friction and prevent corrosion.
Safety System Inspection: Regularly test the sensitivity of the light curtain guards and the emergency stop button to ensure the four-tier safety protection system is functioning at its best.
