Electrochemical marking has long been a cornerstone of part identification and traceability across various industries. At Universal Marking Systems, we've witnessed and contributed to the evolution of this technology, adapting and refining it to meet the changing needs of modern manufacturing.
The Origins of Electrochemical Marking
Electrochemical marking, also known as electrolytic marking, originated in the mid-20th century as a reliable method for marking metal surfaces. It was initially developed as a cost-effective alternative to mechanical engraving and stamping, which were limited by their inability to mark delicate or thin materials without causing distortion.
How does Electrochemical Marking work?
The process involves applying a specially formulated electrolyte to the surface of a metal part, followed by the application of an electric current through a stencil. The current causes a controlled chemical reaction, which etches the desired mark—such as text, logos, or barcodes—into the metal surface. This method was particularly advantageous because it allowed for precise, high-contrast marks without compromising the integrity of the part.
Key Milestones in Electrochemical Marking
Over the years, several key advancements have propelled electrochemical marking from a niche technology to a widely adopted solution across industries such as aerospace, medical devices, automotive, and electronics:
- Improved Electrolyte Formulations: Advancements in chemistry has led to the development of a wider range of electrolytes to suit most metals with an emphasis on health and safety utilising water based solutions.
- Stencil Technology: Initially, stencils for variable information were created with manual data input and were of a relative low quality. Today, with the advent of our POD software and high quality thermal stencil material we can achieve highly detailed and consistent marks quickly, even on complex surfaces. Process improvement has also been achieved with the ability to import data easily to minimise operator error.
- Power Supply Innovations: Modern power supplies are compact, efficient, and offer precise control over voltage and current, allowing for consistent and repeatable results. At Universal Marking Systems, we've incorporated digital interfaces into our power supplies, giving operators greater control and adaptability in their marking processes.
