Hydraulic Logo Stamping Machine

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

Yes, the machine supports precision pressure adjustment.

(1) 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.

(2) 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.

(1) Precision Alignment: We customize branding dies (stamping dies) based on your specific casting bar dimensions.

(2) 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:

(1) Pressure Precision: Minting requires extreme precision for intricate relief; this stamping machine is optimized for hallmarking and logo identification.

(2）Action Logic: Minting requires a "Fast Down — Slow Pressing — Slow Return" cycle to ensure full metal flow into fine details.

（3）Speed vs. Aesthetics: This machine is designed with a "Fast Up/Fast Down" logic to maximize stamping speed. While excellent for logos, it may not meet the aesthetic requirements of proof-like minted coins.

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 machine 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 optimised to operate at under 75 decibels24. Its compact footprint, 110 *85 *135 cm, 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:

（1）Light Curtains: High-sensitivity infrared sensors stop the machine instantly if a foreign object enters the stamping zone.

（2）Dual Start Logic: In semi-automatic mode, the operator must press two buttons simultaneously with both hands to prevent injury.

（3）Flexible Controls: Choose between manual or semi-automatic modes, with the option for dual-button or foot-pedal control.

（4）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.

(1) Warranty: CDOCAST provides a 2-year quality guarantee, including free replacement of non-wear parts.

(2) 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:

（1）Guide Pillar Lubrication: Regularly apply lubricant to the four chrome-plated guide pillars to minimise friction and prevent corrosion.

(2) Hydraulic Oil Management: Periodically check the hydraulic oil levels and ensure the fluid remains clean according to the operation manual.

(3) 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.
