Aluminium Shell Dot Peen Marking Needle

This is our self-developed aluminum shell series marking needle, which is used in our conventional handheld and desktop pneumatic dot-peen marking machine series and can be flexibly customized according to the actual marking needs of customers. The most commonly used model is L4-17.2-65-M26, which means 4mm needle core diameter, 17.2mm base inner diameter, 65mm total length, and M26 thread installation. We choose to use aluminum shell for this series of needles because it has good corrosion resistance and is easy to process.

We use the precise tolerance control of ±0.002mm and the copper inlay on the needle sleeve to avoid needle jamming and improve the disadvantage of aluminum shell’s relatively poor wear resistance. Its weight is less than that of steel shell or copper shell, and the weight and inertia under the module are smaller, achieving more accurate marking effect. The standard needle core uses tungsten steel with a hardness of 92 HRA, which has excellent wear resistance and a typical service life of 2,000 working hours.

It can excellently mark various metal materials with a hardness of less than 60 HRC. In addition, tungsten carbide steel needle cores with a hardness of up to 96 HRA can also be used, which can meet the marking of hard metals such as hardened high-carbon steel with a hardness of less than 65 HRC. In addition, we can also provide our proud enhanced needle tip technology for most standard needles. Whether it is double-angle, titanium-plated or diamond-studded needle tips, they can be customized based on standard needles to achieve higher hardness or wear resistance.

Application Context for Aluminium Shell Dot Peen Marking Needle

This page is part of CNMarking’s Dot peen and scribe marking content library. For buyers comparing similar equipment, the key question is not only whether the sample can be marked, cleaned, welded, or processed, but also whether the final setup can match production speed, fixture stability, marking depth, visual quality, and long-term maintenance requirements. The application is most relevant to permanent identification on metal parts, VIN and chassis numbers, nameplates, flanges, cylinders, rods, and industrial traceability components.

When evaluating a similar project, CNMarking normally checks the workpiece material, available marking area, expected cycle time, required code or logo content, fixture method, safety enclosure needs, and whether the process must connect with an existing line, MES, scanner, or operator workflow. These details help choose between a standard machine, a semi-custom workstation, or a fully automated solution.

How to Choose a Similar Setup

  • Send clear photos or drawings of the workpiece, including the required marking or processing position.
  • Confirm the material, surface coating, required depth or contrast, and any durability requirements after cleaning, painting, heat treatment, or outdoor use.
  • Share the expected production rhythm, such as pieces per hour, operator loading method, fixture constraints, and whether automatic code reading is required.
  • For new applications, request sample testing first so the marking quality, processing speed, and fixture plan can be confirmed before mass production.

FAQ

Can CNMarking test my own samples before quotation?

Yes. For most marking, cleaning, welding, and precision laser processing projects, sample testing is the safest way to confirm process feasibility. A short video, test photos, and recommended configuration can be prepared after the workpiece and target result are confirmed.

What information should I send for a faster recommendation?

Please send the material, dimensions, required content, target cycle time, production environment, and any automation requirements. If the project is replacing an existing process, also share the current pain point, such as low efficiency, unstable quality, consumable cost, surface damage, or traceability requirements.
