Micro Percussion Marking Machines
Industrial Marking Machines

Dot peen marking is an industrial marking technique that uses a controlled impact system to create permanent marks on a variety of surfaces.

This method is based on the use of a punch that strikes the surface of the material at high frequency, generating a series of small impressions that form text, logos, barcodes or serial numbers.

• Durability: Marks made by this method are deep and tough, making them ideal for demanding environments where high resistance to wear, corrosion and abrasion is required.
• Accuracy: Enables fine and clear detail, which is crucial for the precise identification of products and components in industries such as automotive, electronics and machine manufacturing.
• Versatility: It can be used on a wide variety of materials, including metals, plastics and composites, making it a flexible choice for different industrial applications.
• No consumables: Unlike other marking methods, dot peen marking does not require additional consumables, which reduces long-term operating costs.
• Process integration: Dot peen marking machines can be easily integrated into existing production lines, optimizing workflow and improving operational efficiency.

Dot peen marking is a versatile technique that can be applied to a wide range of materials, including:

1. Metals

• Steel: Including stainless steel and carbon steel, which are common in the manufacture of tools and machinery.
• Aluminum: Ideal for lightweight components and structures in various industrial applications.
• Copper and alloys: Used in electrical and electronic components due to their conductivity.

2. Plastics

• Polypropylene (PP): Commonly used in the manufacture of packaging and automotive components.
• Polyethylene (PE): Present in consumer products and industrial applications.
• Polycarbonate: Used in applications where high impact resistance is required.

3. Compounds

• Fiberglass and composites used in aeronautical and automotive applications, where lightness and strength are essential.

Dot peen marking is suitable for a wide variety of materials, making it a versatile option for many industrial applications. Its ability to create durable, high-quality marks on metals, plastics and other materials allows companies to effectively meet their identification and traceability needs.

This method of marking stainless steel and other materials is also known as micro percussion or dot marking and consists of making many consecutive impacts that generate a succession of dots. The result is the direct engraving of characters, logos or codes on various surfaces.

In addition, it offers the benefits of being very safe, easy to use and non-polluting. There is also no need to use consumable materials, as the only replaceable part is the punch that performs the dot peen marking.

Some of its advantages are:

• Deep and adjustable markings can be made on a variety of materials.
• It is a technique that allows the marking of parts on both smooth and curved surfaces.
• The high-speed work and the automatism of the machines that perform dot peen marking are two of its major strengths.
• These devices can mark a wide variety of characters, logos and codes.
• They also stand out for their ease of use and, as mentioned above, because the only periodic replacement that needs to be carried out is that of the punch.

In short, they are exempt from any maintenance operation.

Selecting the right choice among the dot peen marking machines to suit your needs depends on several factors related to your processes, materials, workspace and marking requirements.

Here is a practical guide to make the best decision:

1. Type of application

• Fixed or portable marking: If you need to mark large, heavy parts or in remote locations, a portable marker is the best option.

For smaller parts or production processes in a fixed space, a tabletop marker may be ideal.

• Integration into production lines: If you want to automate the marking process in your production line, integrable markers are the perfect solution, as they easily adapt to the workflow.

2. Material to be marked

Consider the type of material to ensure that the marker generates accurate and durable marks. Dot peen markers work well with a variety of materials, such as:

• Metals (steel, aluminum, copper, etc.).
• Plastics.
• Compounds.

If you work mainly with hard materials such as hardened steels, make sure you choose a machine with a strong and powerful punch.

3. Size and weight of parts

• Small and light parts: Table-top machines are often ideal for this type of work.
• Large or heavy parts: A portable marker allows more flexibility to work directly on the component.

4. Content of the marking

• Mark types: Determine whether you need to mark text, serial numbers, barcodes, logos or QR codes.
• Size and depth: If you need deep or visible marks in adverse conditions (such as on wear parts), make sure the machine has the necessary power.

5. Volume of production

• Low volume: If you do occasional marking, a portable machine may be sufficient.
• High volume: For mass production, an integrated or benchtop machine that can run efficiently and continuously is recommended.

6. Ease of use

Choose a machine with intuitive controls and user-friendly software. This reduces training time and improves operational efficiency.

7. Budget

Evaluate the initial cost and long-term savings. For example, dot peen machines do not require consumables such as ink or lasers, making them a more economical solution in the long run.

8. Technical support and maintenance

Opt for a manufacturer like COUTH, which offers reliable technical support, personalized advice and maintenance to ensure that your machine performs optimally for years to come.

For all these reasons, when choosing between dot peen marking machines, you must consider factors such as the type of application, the material to be marked, the size of the parts, the volume of production and your budget. At COUTH, we offer a wide range of solutions (portable, tabletop, integrated or mixed) to suit different industrial needs.
