Industrial Marking: Techniques, Applications, and Materials
Industrial marking plays a critical role in modern manufacturing by ensuring product traceability, compliance, and branding. In this guide, we explore key marking techniques, materials, and applications—helping manufacturers choose the right solution for durable and efficient identification.
Industrial marking is the process of applying permanent identifiers—such as serial numbers, barcodes, logos, or batch codes—on manufactured parts or products. This process ensures reliable traceability, compliance, and quality control across various industries, including automotive, aerospace, medical, and electronics.
Unlike simple labeling or printing, industrial engraving offers long-lasting, resistant, and precise results that withstand harsh environments like high temperatures, abrasion, and chemical exposure. Depending on the material and application, manufacturers can choose from several techniques like laser, dot peen, impact, and electrolytic marking, each offering unique advantages in terms of speed, depth, and durability.

Industrial marking encompasses several technologies, each with unique advantages based on the material, production speed, and durability requirements. Below is an overview of the most prominent marking methods used today.
Laser industrial marking
Laser marking is one of the most precise and versatile methods. It uses a focused beam of light to etch or discolor the material's surface, making it ideal for high-resolution logos, serial numbers, and barcodes.
Key benefits:
Non-contact process
Suitable for metals, plastics, and coated materials
Dot peen marking works by striking the surface with a carbide or diamond stylus to create a series of small indents. It’s widely used for deep, durable marks, especially on metal parts.
Impact marking involves a mechanical force applied through a punch or stamp. It’s a reliable solution for straightforward and cost-effective marking operations.
Advantages:
Simplicity and speed
Great for high-volume applications
Suitable for robust materials like steel and aluminum
Roll marking applies pressure through a rolling motion, ideal for cylindrical or flat metal parts. This method is commonly used for batch numbers, logos, and specifications.
Electrolytic marking uses electrochemical reactions to create marks on conductive materials. It’s popular in the medical and tooling industries for clean and corrosion-resistant results.
Hot marking combines heat and pressure to imprint materials like leather, plastic, or wood. It’s particularly suitable for branding and decorative purposes.
Industrial marking is compatible with a wide variety of materials. According to Automator's materials guide, the most commonly marked materials include:
Metals: steel, aluminum, titanium, brass
Plastics: ABS, polycarbonate, polypropylene
Glass and ceramics
Rubber and silicone
Wood and leather
The marking method is selected based on the material’s hardness, conductivity, and required finish.
