Pin Marking Applications For Permanent Marking

About Pin Marking 

Pin Marking (or pin stamping) is the common phrase referring to a permanent, direct part marking process using a carbide pin to indent the marking surface with text, logos and 2D Data Matrix barcodes. Pin marking machines engrave data deeply into the surface of a material, delivering a durable mark, even in the harshest of manufacturing environments. These marks are also readable after painting or galvanizing.

Their versatility allows them to mark on a wide range of substrates from plastics to hardened steel up to 65Hrc.

Benefits of Pin Marking

MECCO’s high-powered pin marking machines help you create branding, traceability, anti-counterfeiting, and a number of other critical mark types.

The benefits of pin marking include:
  • Durable permanent marks that can withstand tough environments
  • High-speed operations
  • Electric or pneumatic options
  • Portable design
  • Marks metals and some hard plastics
  • Cost effective

Pin Marking and Traceability

An increasingly complex supply chain and regulatory environment has made traceability an essential part of manufacturing. Our pin marking machines deliver deep, permanent, readable marks, ensuring traceability information is in tact no matter the conditions. 

With MECCO’s EtherMark technology, pin marking systems can integrate directly into factory automation networks, connecting operations with invaluable track and trace data. This valuable information enables you to make more informed decisions in real time. 

Pin Marking Materials

Thanks to its power and versatility, pin marking technology is well suited for a range of materials, including:

  • Aluminum
  • Brass
  • Copper
  • Nickel plated/galvanized
  • Plastics
  • Powder coated/painted
  • Stainless
  • Steel

Types of Pin Marking Applications

Deep Marking

Deep Marking

Providing marks that are fast and deep, dot peen marks are readable even after painting, galvanizing, or plating. This application is ideal for pipes, tubes, flanges, and all parts used in indoor and outdoor manufacturing.

Dot Peen

Dot Peen

Dot peen marks are the least intrusive impact mark method and can be produced by either electric or pneumatic systems. Manufacturers across industries can add permanent part information, such as date/time stamping, part serialization, logos, 2D Data Matrix bar code, and operator identification for improved tracking and traceability.

Low-Stress Pinning

Low-Stress Pinning

In order to maintain a part’s strength and durability, dot peen machines can add low-stress marking that avoids compromising a part’s strength. This type of pin marking can be done on a number of materials across a variety of industries.

Scribing machines are a pneumatic system that presses down and drags across the part material. An X,Y stepper motor-driven machine, the depth is controlled by air pressure and the size of the marking head. This system produces a high-quality mark at a reduced noise level.

Vibra Peen

Vibra Peen

Unique to MECCO’s line of COUTH dot peen products, Vibra Peen™ technology improves upon the quality and readability of your marks by increasing the pulsing of the carbide pin to form continuous lines.

Because of these valuable benefits, 97% of our customers use Vibra Peen over dot peen due to its enhanced speed, appearance, and depth of mark.

Choosing a Pin Marking System - Pneumatic or Electric Dot Peen Marking System?

Pneumatic Pin Marking Systems

Pneumatic systems allow for deeper, smoother looking marks at a much faster marking speed. They can produce traditional dot peen marks or the more continuous Vibra Peen™ type marks. 

Pneumatically driven systems use air pressure to drive the stylus/pin down into the material, which offers more force than electric driven solenoid systems.

Adjusting the amount of air pressure entering the system increases or decreases the marking depth. The use of air pressure allows for the stylus to travel up and down between 80 and 100 times per second. This is what creates the smooth looking mark.

Marking Depths on Mild Steel:

  • N-07: .001" - .003" deep
  • N-14: .003" - .008" deep
  • N-20: .005" - .012" deep
  • N-34: .008" - .020" deep

Electric Pin Marking Systems

Electric systems are best for low stress marks and can only produce the dot peen type. The stylus does not cycle up and down fast enough to produce the more continuous marks of the Vibra Peen™ machines.

If you lack an air compressor or are unable run air lines to the area for part marking, then choose an electric system to produce a dot pattern that can easily create text, characters, and 2D Data Matrix.

Mark Depths on Mild Steel:

  • S-02: .003" - .008" deep
  • S-06: .005" - .012" deep
