What is the Difference Between Pin Marking and Scribe Marking?
Both pin marking and scribe marking are methods used for marking various materials, components, or products. These marking techniques serve to engrave identifying information, such as serial numbers, batch codes, dates, logos, or other important data, to aid in tracking, identification, quality control, and traceability throughout the manufacturing process and the product's lifecycle. However, they achieve this in different ways, each with its own set of advantages and considerations.
PIN MARKING
Pin marking (also referred to as stylus marking and dot peen marking) is the use of a carbide pin assembly that oscillates pneumatically or electrically to strike the surface of a part in a sequence of dots to produce a permanent mark. Depending on the type of pin assembly, power settings, and marking speed parameters, pin marking can create light, moderate or deep marks on the surface of parts.
Advantages:
- Fast and efficient marking process with high-speed capabilities.
- Suitable for marking a wide range of materials, including most metals and some hard plastics.
- Can achieve finer more detailed marks due to variety of stylus options.
Considerations:
- Can be noisier than scribe marking depending on mark parameters and type of material.
- Stylus assemblies wear out faster
SCRIBE MARKING
Scribe marking also uses a pneumatic or electromechanically controlled carbide tip assembly. However, instead of striking the part, it uses a drop-and-drag technique to drag the pin across the surface of the part, quietly creating a continuous mark. Scribe marking is often used for harder materials and provides a more deeply etched mark compared to pin marking.
Advantages:
- Best for environments where normal impact marking would exceed acceptable decibel levels.
- Creates a continuous mark with extremely clear character definition.
- Suitable for marking harder materials like metals, glass, and ceramics.
Considerations:
- Not as well-suited for high-speed production lines.
- Less stylus pin sizes to choose from.
- Scribing pin has less throw than with pin marking.
Is Pin Marking or Scribe Marking Better For You?
The choice between pin marking and scribe marking depends on factors such as material type, required marking depth, marking speed, precision, and the specific production environment. Manufacturers need to evaluate these factors to determine which method is best suited for their application to ensure clear, accurate, and durable markings that meet their needs.
